Definitions
- Giant! Capable, plastic, carbon-containing, refractory mass
- the invention relates to a free-flowing, plastic, kohlstoff ⁇ containing, refractory mass for lining containers for liquid steel.
- pan linings made of magnesia, magnesia chromite and dolomite stones have prevailed.
- pan delivery devices that are able to automatically insert the delivery masses and to compress them sufficiently. These include the so-called Slinger systems and the automatic pan stacker systems.
- Slinger systems When slinging, the plastic mass undergoes great acceleration at the end of a conveyor belt and is thus removed from the pan crown, i.e. the top edge of the pan, inserted down between a template and the mostly existing permanent or insulating lining of the pan.
- the large mass throughput results in a short delivery time.
- there is no uniform compaction since there is grain rebound and grain segregation and this leads to the formation of coarse grain nests. There is therefore a non-uniform mass build-up.
- Refractory ramming compounds which are provided with a thin tar or pitch additive in order to achieve the required plasticity, also prove unsuitable because the smoke that occurs during the drying of these plasticizing additives prevents the use of tar and pitch for environmental reasons.
- magnesia carbon stones are produced by sintering magnesia with a content of over 90% by weight MgO with carbon, e.g. Graphite, mixed in a ratio of 70 to 95 to 5 to 30, 2 to 6% by weight of novolakphenol resin solution, based on the weight of the magnesia-carbon mixture, and 8 to 20% by weight of a hardener, based on the weight of the Novolakphenolharz admits, forms the mixture into stones and dries them.
- Such a mixture which is only intended for stone production, is not suitable as ramming paste because it is not stable in storage in the unforforced state.
- This mass which has a pulp-like consistency, is not suitable for compaction by means of pounding or the like, because it is not self-supporting and cannot be removed.
- the object of the invention is the development of a free-flowing, carbon-containing, refractory mass which remains storable and processable over a long period of time, for example over two months or more, or the like in pans.
- Containers for liquid steel can be introduced and compacted by manual or automated tamping, by slinging or by shaking or vibrating and, when heated, smoke can be largely avoided.
- This object is achieved according to the invention with a mass, the granular refractory material, 1 to 20 wt .-%, preferably 4 to 10 wt .-%, a solid carbon carrier in the form of graphite, carbon black, ground coke powder, electrode breakage or the like. or mixtures thereof and 2 to 7% by weight of a storage-stable, thermosetting, hardener-free synthetic resin, preferably a phenolic resin of the Novolak type.
- the synthetic resin can be in solid, finely ground form, preferably in a grain size of less than 0.2 mm with a proportion of grain size of less than 0.06 mm.
- a lubricant and plasticizer is recommended in order to bring the mass into a plastic state suitable for compaction by tamping, slinging or shaking.
- liquid aliphatic hydrocarbon namely naphthenic oil or paraffin-based oil, or silicone oil can be considered as such an agent.
- This lubricant can be added to the mass delivered in a dry, granular state before it is introduced into the container to be lined.
- the synthetic resin can be dissolved in an anhydrous solvent, such as ethylene glycol or polyethylene glycol.
- the solvent acts as both a lubricant and a plasticizer.
- the composition according to the invention thus has an organic bond which is achieved by using a storage-stable thermoset, ie a thermosetting synthetic resin, in particular a phenolic resin and preferably one of the novolak type, the addition of a hardener being avoided.
- the phenolic resin can also be modified, for example with natural resins.
- the composition of the invention surprisingly sets in the heat even without a hardener.
- This binding has the advantage that hardly any reactions occur during the storage of the mass, and accordingly a shelf life of at least two to three months and above is achieved.
- liquid synthetic resins e.g. Resoles
- catalysts especially divalent metal ions such as Mg, Ca, Cd, Mn
- Synthetic resin achieves the plasticity required for processing the mass, the mass is free-flowing and has an earth-moist consistency.
- the proportion of plasticizer in the case of compaction by tamping in the lower range of the above amount in In the case of slinging in the middle range of this and in the case of shaking or vibrating in the upper range of this amount. It can be assumed that the mass according to the invention, owing to the addition of oil or glycol, is less prone to grain segregation when slinging than the known masses.
- the composition according to the invention has sufficient green strength so that it can be removed immediately after compression. As a result of this property, it is also suitable for compaction by means of a ramming machine, which is used without a built-in template, in which rather only a local template-like structure that migrates with the ramming device, e.g. in the form of a link belt is provided.
- Sintered and / or melted magnesia is particularly suitable as the refractory base material for the composition according to the invention, preferably with an MgO content of over 85% by weight.
- refractory base materials that have a sufficiently high erosion resistance to melts can also be used. These are, for example, spinel (such as magnesium aluminum spinel), magnesium silicate material (such as forsterite or olivine), irirconium (zirconium silicate), corundum, alumina or andalusite.
- the refractory material is expediently used in a manner known per se in a grain size which ensures a relatively high packing density.
- the mass has a portion of a solid carbon carrier in the form of graphite, soot, ground coke powder, electrode breakage, coal pomace or. the like or mixtures thereof.
- the mass can contain metal powder, such as aluminum, silicon, magnesium or alloys, and / or finely ground carbide, such as silicon carbide or boron carbide, in amounts of 1 to 7% by weight.
- the metal oxides formed during the oxidation of these substances protect those required to maintain the bond and to protect against melt and slag infiltration Carbon before oxidation.
- Such substances are known per se as protection against oxidation. At installation sites not exposed to the oxidizing effect, the oxidation protection can be omitted.
- Example 1 Sintered magnesia with 97% by weight MgO and 0.2% by weight Fe2 ⁇ 3
- Example 3 Zircon ZrSi ⁇ 4 0 - 5 mm 84 wt
