Definitions

  • the present invention relates to a high-temperature lubricant for the hot forming of stainless and carbon steels, which has a content of graphite, organic blowing agent and inorganic release agent.
  • the invention further relates to the use of the high-temperature lubricant according to the invention.
  • so-called carburizing of the rolling stock may take place in the region of the grain boundaries of the rolling stock upon contact with the lubricant at forming temperatures of the order of 1100 to 1300 ° C., with carbon being diffused into the metal surface and added to it partial embrittlement of the metal and hole formation with penetration depths up to about 300 ⁇ m can occur.
  • the embrittlement of the metal during further processing of the workpiece causes the embrittled material to rupture and the workpiece becomes unusable. Pit formations are rolled in the subsequent Elongierprozeß to Lijnsriefen. These grooves represent a significant, unacceptable quality degradation of the finished rolling, which must be avoided.
  • Lubricants for the application of stainless steel forming are e.g. in EP-A-0 357 508. However, these are optimized for this application and therefore not optimal for the transformation of carbon steels in terms of tool life and power consumption of the rollers.
  • Lubricants for the field of carbon steel forming are described, for example, in the patents EP-A-0 164 637, EP-AO 554 822 and EP 0 909 309. These lubricants can be converted under comparable conditions only higher alloyed materials, if in addition a powdered deoxidizer supports the lubricating effect.
  • EP 0 745 661 discloses a graphitic lubricant having a proportion of one or more clay minerals from the class of smectites. In addition, these lubricants either have a content of silica sol or potassium aluminum silicate. According to EP 0 745 661, such lubricants can largely overcome the disadvantage of carburizing graphite-containing lubricants at relatively high operating temperatures. Although such lubricants containing graphite and phyllosilicate may have less carburization in metalworking, they often require improvement in the friction ratios between the metal surfaces to extend the life of the tooling, such as mandrel bars.
  • the object of the present invention was to provide a usable for a wide range of steel grades for different wall thicknesses and dilations to be rolled high temperature lubricant, which is also temperature stable, consistent rolling results in changing the wall thickness and / or steel quality and not to undesirable carburization of Walzgut leads.
  • a high-temperature lubricant of this type has not been described.
  • a high-temperature lubricant for the hot forming of stainless steels and carbon steels which contains at least the following constituents in% by weight, based on the solids content:
  • organic blowing agent (b) is selected from the group consisting of
  • Mixtures of the aforementioned, and the inorganic release agent (c) is a layered silicate or a mixture of layered silicates.
  • the high-temperature lubricant composition according to the invention surprisingly exhibits outstanding lubricating and separating properties as a lubricant which can be used universally for a wide variety of steel grades during hot forming, in particular in rolling processes for the production of seamless tubes.
  • the lubricant according to the invention is stable at high temperatures, gives consistent rolling results with a wide variety of steel grades and with varying wall thicknesses, and does not lead to a higher degree of carburization, which damages the rolling stock, despite the high carbon or graphite content.
  • the high-temperature lubricant according to the invention has the significant advantage over previously known lubricants for the hot forming of metals that only a single lubricant formulation needs to be used in a rolling mill for a wide variety of steel grades. As a result, longer production interruptions, increased labor costs for the replacement of the lubricant and the provision of various lubricants are avoided when changing the steel grade in the machining process. Furthermore, due to the universal lubricant of the present invention, it is not necessary to provide separate facilities for producing, storing, and applying further lubricants in a rolling mill. As a result, significant costs can be saved.
  • the graphite with its excellent lubricating properties is contained in the high-temperature lubricant according to the invention, based on the solids content, in an amount of 40 to 90 wt .-%.
  • an amount of less than 40 wt .-% graphite the lubricating properties of the high-temperature lubricant according to the invention are insufficient, the driving forces of the outer tools increase and the material to be formed "flows" too little.
  • With an amount of more than 90 wt .-% graphite no sufficient separation effect between rolling stock and mandrel can be guaranteed. In particular, stainless steels tend to adhere to the tools.
  • the high-temperature lubricant contains from 50 to 80% by weight of graphite, based on the solids content.
  • the graphite used in the high-temperature lubricant is crystalline or macrocrystalline graphite, preferably crystalline or macrocrystalline natural graphite.
  • the use of amorphous graphite has proved to be unsuitable, since the lubricating properties of high-temperature lubricant deteriorate when amorphous graphite is used, and this has a direct detrimental effect on the service life of the tool.
  • the use of spheroidal graphite has proved to be totally unsuitable.
  • the graphite has a purity of> 90%, preferably> 95%, based on the carbon content of the graphite.
  • the use of graphite with a purity of less than 90% has proven to be unsuitable, since the impurities and impurities favor the formation of carburization while reducing the lubricity due to the lower graphite content in the composition.
  • a crystalline natural graphite suitable according to the invention usually has a purity of about 96%.
  • the graphite has an average particle size (d50) of 5 to 40 ⁇ m, preferably 10 to 25 ⁇ m.
  • d50 average particle size
  • the use of graphite having an average particle size of less than 5 ⁇ m is unsuitable because there is no longer sufficient platelet structure and this results in a lower lubricating effect.
  • the use of graphite with an average particle size of more than 40 microns is unsuitable, since this brings platelet sizes, which have disadvantages in handling due to strong sedimentation tendency.
  • Natural graphite of the aforementioned purity contains other ingredients as impurities or admixtures, such as u.a. Silicon in the form of silicon carbide (SiC) or silicon oxide (SiC> 2). Since silicon carbide and silicon oxide have a highly abrasive effect, too high a silicon content in the graphite used according to the invention leads to undesirably high abrasion of the tool and / or of the workpiece.
  • the graphite used therefore contains silicon as impurity or admixture in an amount of not more than 2.0% by weight, preferably not more than 1.5% by weight, more preferably not more than 0.2 wt .-%.
  • the high-temperature lubricant according to the invention contains organic blowing agent in an amount of 2 to 50 wt .-%.
  • the organic blowing agent is selected from nitrogen compounds of the above definition.
  • the organic blowing agent consists of 100% by weight of melamine isocyanurate.
  • the organic blowing agent used in the high-temperature lubricant according to the invention releases at elevated temperatures, preferably temperatures> 350 0 C, gas and thus forms a gas cushion between the tool and the workpiece during the forming of the workpiece at the usual forming temperatures.
  • Gas formation occurs either by decomposition of the organic blowing agent, by sublimation or both.
  • An amount of less than 2% by weight of organic blowing agent leads to insufficient gas formation or gas release, so that a sufficient gas cushion can not be formed between the tool and the workpiece.
  • An amount of more than 50% by weight of organic blowing agent is unfavorable, since uncontrolled high gas formation and associated disturbance of the rolling process due to gas expansion can occur.
  • Melamine isocyanurate is particularly suitable for this purpose.
  • the high-temperature lubricant contains organic blowing agent in an amount of 3 to 10 wt .-%, preferably 4 to 6 wt .-%. An amount of about 5% by weight of organic blowing agent has proven particularly suitable.
  • the high-temperature lubricant according to the invention further contains a layered silicate or a mixture of layered silicates as an inorganic release agent in an amount of 5 to 50% by weight.
  • a content of the inorganic releasing agent in an amount of less than 5% by weight is unsuitable because a sufficient releasing effect is not obtained.
  • An amount of more than 50% by weight of organic release agent leads to reduced lubricity.
  • the high-temperature lubricant contains the inorganic release agent in an amount of 10 to 40 wt .-%, preferably 15 to 30 wt .-%.
  • the inorganic release agent is selected from kaolinite, antigorite, hydrohalloysite, serpentine, greenalite, pyrophyllite, talc, margarite, vermiculite, sudoite and chlorite. Particularly preferred are kaolinite and antigorite alone or in admixture.
  • the inorganic release agent is selected from the group of alkali-free hydrous sheet silicates with two-component single-layer, such as kaolinite, antigorite and halloysite. Very particular preference is given among the layered silicates to the clay mineral kaolinite, an aluminum hydrosilicate of the general formula Al 2 [Si 2 O 5 (OH) 4 ].
  • Kaolinite is obtained either by slaking the clay kaolin or synthetically from polysilicic acid and aluminum hydroxide. Since kaolins consist predominantly of the mineral kaolinite (about 88%), in specific embodiments of the present invention kaolin can also be used instead of pure kaolinite. The advantage of using the clay kaolin is the lower cost of the raw material compared to the use of pure or, for example, synthetically produced kaolinite. Kaolin is therefore preferably used according to the invention. On the other hand, however, the higher purity of the mineral kaolinite or the highest possible purity of the synthetically produced kaolinite may be desired for the purpose of a more exact reproducibility of products of uniform quality.

  • d50 average particle size of 0.5 to 15 .mu.m, preferably 1 to 10 .mu.m, particularly preferably 1 to 7 .mu.m.
  • Smaller particle sizes than 0.5 microns have the disadvantage that it comes to agglomeration of the raw material and this can not be sufficiently homogenized well in the powder mixture.
  • Particle sizes of more than 15 microns have the disadvantage that thereby the release effect of the release agent is partially superimposed by an adversely effecting abrasive action and beyond can be produced at very different particle sizes no homogeneous mixture.
  • the high-temperature lubricant contains from 1 to 20% by weight of organic adhesive selected from alkylene homopolymers and copolymers.
  • the adhesive is suspendable in water and forms on the substrate (tool and / or workpiece) a film which helps to maintain the remaining components of the composition of the lubricant.
  • An amount of less than 1 wt .-% of the organic adhesive is insufficient, since thereby reduce the layer thicknesses of the lubricant used to an insufficient level.
  • An amount of more than 20 wt .-% organic adhesive has the disadvantage that the lubricating effect is reduced due to the lack of Graphitanteils and thus reduce tool life.
  • the high-temperature lubricant contains the organic adhesive in an amount of 2 to 10 wt .-%, preferably 2 to 5 wt .-%.
  • the organic adhesive is homopolymers and copolymers of arylalkenes, ⁇ , ßunsaturated acids and esters, ß, ⁇ -unsaturated acids and esters, alkenes, vinyl esters, vinyl alcohols, unsaturated dibasic acids and Esters, alkyl esters and acyclic acids and esters.
  • the organic adhesive is polyethylene, polymethyl methacrylate, polystyrene, polybutadiene, polyvinyl acetate, polyvinyl propionate, copolymer of methyl methacrylate and styrene, copolymer of methyl methacrylate and alpha methyl styrene, polydiallyl phthalate, polypropylene, copolymer of styrene and butadiene, polymethyl methacrylate, copolymer Vinyl acetate and dibutyl maleate, copolymer of vinyl acetate and ethylene and polyisobutylene selected.
  • the high-temperature lubricant further contains from 2 to 15% by weight of inorganic or organic stabilizer, the stabilizer being chosen from polysaccharides, alkylcelluloses, hydroxycelluloses and clay minerals.
  • the high-temperature lubricant according to the invention is often or commonly used in the application as a suspension or dispersion in a liquid, preferably in water.
  • the inorganic stabilizer increases the viscosity in this suspension or dispersion and thus serves as a thickener and prevents or reduces the sedimentation and thus the separation of the other constituents of the high-temperature lubricant.
  • An amount of less than 2 wt .-% of the stabilizer is undesirable, since then the increase in viscosity is not sufficient to prevent sedimentation of the components of the high-temperature lubricant sufficiently and to ensure the homogeneity of the lubricant.
  • An amount of more than 15 wt .-% of the stabilizer leads to an increase in viscosity of the suspension or dispersion, so that it can be applied to the tool only poorly in the spray process. In addition, too high a viscosity can affect the formation of a sufficiently coherent and uniformly thick lubricant film.
  • the high-temperature lubricant contains the stabilizer in an amount of 3 to 10% by weight, preferably 4 to 6% by weight.
  • the stabilizer is particularly preferably an inorganic material which is selected from silicate-based clay minerals or mixtures thereof, preferably bentonites and organically modified bentonites. Most preferably, the stabilizer is under Ton- minerals selected from the class of smectites, preferably the class of montmorrionites.
  • Smectites consist essentially of phyllosilicates and are structurally characterized by a high cation exchange capacity and by high swellability in water. From the class of smectites it is particularly preferred to use montmorrionites which have a swelling capacity (1 g montmorrionite in distilled water) of from 3 to 50.
  • the smectites or montmorrionites can be "modified" with inorganic or organic cations.
  • the clay minerals used with advantage in the high-temperature lubricant according to the invention are distinguished by excellent binding properties and moreover have the advantage that, in contrast to organic stabilizers, they do not
  • the use of said clay minerals leads to a surprisingly fast drying time of the lubricant film on the workpiece and / or the tool within a few seconds.With the use of these stabilizers, it is possible with the lubricant according to the invention on the tool and / or the To produce a uniform and dry lubricating film within a very short time, even before the tool and the workpiece are brought into contact.
  • the high-temperature lubricant according to the invention is expediently provided as a powdery, dry solid. It can also be used directly as such a solid, but it is advantageous in the application as a suspension or dispersion in a liquid, preferably water, having a solids content of 5 to 50 wt .-%, preferably 15 to 40 wt .-% , particularly preferably 25 to 30 wt .-% to use.
  • the high-temperature lubricant can be sprayed evenly on the tool and / or the workpiece. Due to the elevated temperature of the tool and / or the workpiece, the liquid evaporates leaving a uniform solid coating of the lubricant.
  • the high-temperature lubricant according to the invention can also be marketed as such a suspension or dispersion.
  • the solid constituents of the high-temperature lubricant have an average particle size ⁇ 200 .mu.m, preferably ⁇ 150 .mu.m, particularly preferably ⁇ 100 .mu.m. If the solid constituents of the high-temperature lubricant have a higher average particle size, this has the disadvantage of an increased sedimentation tendency in suspended application form. Further advantages, features and embodiments of the present invention will be explained with reference to the following examples.
  • lubricant formulations were tested in longitudinal rolling processes. The formulations were each used as 30% aqueous suspensions. All percentages by weight relate in each case to the solids content.
