Definitions

the present invention relates to a method of supplying lubricant during hot rolling.
a lubricant is provided to the surfaces of the rolling rolls, to reduce the frictional forces acting on the areas between the rolling rolls and the rolled material, or to prevent wear and tear. the gluing of the rolling rolls of the rolling mill, thus producing steel products with a good surface quality.
Lubricants and their methods of supply are known, and in particular (a) a method in which a lubricating oil is mixed with the water and lubricant in emulsion form, and is then supplied by injection or by any other method similar, and (b) a steam atomization process in which a lubricating oil and steam are mixed together and the mixture is supplied by injection, and (c) an atomization method in which a lubricating oil is atomized by using air, gas, etc.
the thickness of the strip of a rolled material is large compared to that obtained after cold rolling and the rolling mill is not equipped with a device which facilitates the commitment of laminated materials. For this reason, tape engagement at the cylinder inlet, as well as during rolling, can occur.
a method can be used in which the amount fed with lubricating oil is reduced and lubricating oil is supplied as long as slip problems do not occur. It is also possible to use a method in which the sliding engagement between the rolls is avoided by not lubricating at all when the start and end ends of the rolled material are engaged in the rolling mill.
a lubricant is obtained by emulsifying a lubricating oil having a high coefficient of friction, and using it to prevent slippage on engagement between the cylinders when the ends The beginning and end of the rolled material are engaged in the rolling mill.
the viscosity of a lubricating oil is increased and its adhesion to the rolling rolls is improved to suppress variations in the amount of adhering lubricating oil, then the lubricating oil adheres to the inner wall of the lubricating oil.
lubricating oil supply piping and fouling, or even the mouth. This clogging of the pipework also generates unexpected variations in the concentration of the lubricating oil.
the interior of an injector in which the lubricating oil is mixed with water has an orifice structure and the lubricating oil passes through a pipe having a small inner diameter. A high capacity pump is required for a high viscosity fluid (the lubricating oil) to pass through this small inner diameter pipe.
the object of the present invention is to provide a method of supplying lubricant which makes it possible to obtain a constant lubricating effect without being affected by the ambient temperature, by emulsifying a lubricating oil of high viscosity without causing fouling of the pipes, and supplying the rolling rolls with lubricant of high viscosity.
the present inventors have solved the above-mentioned problems by a method of emulsifying a lubricating oil by the water injection process, by (a) maintaining the lubricating oil in a relatively low viscosity state up to lubricating oil is injected from a nozzle, to prevent clogging of the lines and (b) changing the lubricating oil to a relatively high viscosity state when the lubricating oil is emulsified and injected from the nozzle, to increase the adhesion efficiency to the rolling mill rolls, said efficiency being defined as the ratio of the amount of the lubricant adhered to the rolling mill rolls with respect to the amount of lubricant supplied from the lubricant supply nozzle.
the object of the invention is constituted by a method of supplying lubricant during hot rolling, in which the surfaces of the rolling rolls are fed with a lubricating emulsion, characterized in that said emulsion lubricant, consisting of a lubricating oil having a viscosity of between 10 cSt and 400 cSt at 40 ° C. mixed with water, is sent to the surfaces of the rolling rolls through at least one lubricant supply nozzle, at a temperature above 0 ° C. and below 25 ° C.
the lubricating emulsion is cooled in the lubricant supply nozzle at a temperature greater than 0 ° C and below 25 ° C, and then sent to the surfaces of the rolling rolls.
the method according to the invention is such that the temperature of the lubricating oil contained in the lubricating emulsion is greater than 20 ° C. before mixing with water.
the process according to the invention is such that the temperature of the water contained in the lubricating emulsion is between 0 ° C. and 25 ° C. before mixing with the lubricating oil.
Figure 1 shows the schematic of a lubricating oil supply piping system, which emulsifies a lubricating oil by water injection mixing and provides the emulsified lubricating oil to the rolling mill rolls.
This system is industrially the most used at the current time.
the invention is based on this system as a prerequisite.
a lubricating oil having a viscosity at 40 ° C. of more than 10 cSt but less than 400 cSt is mixed with water by the use of an injector of an injection system of water to obtain a lubricating emulsion
one of the following methods may be used: (i) after mixing of a lubricating oil and water by the injector, the mixture is cooled to a temperature between 0 0 C and 25 ° C and is then injected, or
a lubricating emulsion which is obtained by mixing a lubricating oil, preferably at more than 20 0 C, is mixed with water having a temperature between 0 and 25 ° C in an injector, and is injected by a nozzle at a temperature between 0 and 25 ° C.
the viscosity changes are of the order of a factor of two to four in the temperature range of 10 to 40 ° C., a temperature range which corresponds to that observed for the temperature of the product. in winter and in summer.
the viscosity of a lubricating oil is less than 10 cSt at 40 ° C.
the viscosity at an injection temperature of between 0 and 25 ° C. becomes insufficient and the adhesion efficiency to the rolling mill rolls (ratio of The amount of lubricant adhering to the rolling mill rolls relative to the amount of lubricant supplied from the lubricant feed nozzle greatly decreases, resulting in the inability to have sufficient lubrication effect.
the lower limit for the viscosity of a lubricating oil is therefore set at 10 cSt at 40 ° C.
the viscosity of a lubricating oil be not less than 100 cSt at 40 ° C.
the viscosity of a lubricating oil exceeds 400 cSt at 40 0 C, it generates clogging and clogging of the pipes.
the lubricating oil becomes semi-solid, which is called a grease state and, therefore, the lubricating oil does not can not be mixed with water even by the water injection process.
lubrication becomes excessive even when mixing is possible and this generates slip problems. Therefore, the upper limit to the viscosity of a lubricating oil is set at 400 cSt at 40 ° C.
the viscosity of the lubricating oil does not exceed 300 cSt at 40 0 C.
the invention utilizes the adhesion properties of lubricating oils, for which the higher the viscosity of the lubricating oil, the greater the adhesion efficiency to the rolling mill rolls.
the viscosity at 40 ° C. is not less than 10 cSt, but not more than 400 cSt, then even the currently used lubricating oils can be used without making investments in heavy equipment (e.g. , increasing the capacity of the pumps, increasing and renewing the piping equipment) and on top of that, it is possible to increase the lubrication effect compared to the current level.
the viscosity changes approximately a factor of two to four in the temperature range of 10 to 40 ° C (corresponding to changes in water temperature in winter and the 'summer).
a heater and a mixer are provided in the lubricating oil reservoir and the maintenance of the lubricating oil temperature is controlled at a constant level.
the temperature of the water with which a lubricating oil is mixed has not been controlled so far, and the situation is such that the water is used at its natural temperature, which changes according to the outside temperature of the air. .
the temperature of the lubricating emulsion is adjusted to a temperature range of 0 ° C to 25 ° C at the time of injection from a nozzle. supply of lubricant, and preferably from 0 to 15 ° C.
the viscosity of the lubricating oil is maintained in a prescribed high viscosity range and the adhesion of the lubricant to the rolls is increased, and at the same time a prescribed amount of lubricant is supplied to the rolling mill rolls without being affected by seasonal factors during the year.
the viscosity of the lubricating oil is adjusted at the moment of ejection of the lubricant supply nozzle and the viscosity of the lubricating oil can be increased without changing the lubricating oil itself. . Therefore, the lubrication effect by the lubricant can be increased without substantially modifying the lubricant supply equipment.
the water having a temperature between 0 0 C and 25 0 C is fed into an injector, a lubricating oil is mixed with this water and the mixture is injected from a feed nozzle lubricant, the temperature of the mixture being maintained (mixing mode (ii) above).
mixing mode (ii) above it is possible to adjust the temperature of the water to not less than 0 ° C., but no more than 25 ° C., to mix the water with a lubricating oil and to inject and supply the water.
the proportion by volume of lubricating oil is from 0.5 to 5 parts per 100 parts of water, and preferably from 0.5 to 2 parts of oil per 100 parts of water.
the temperature of the lubricating oil itself decreases in the piping from the injector to the nozzle, but the mixing ratio of the lubricating oil in the emulsion is very low. So, even when the temperature of the lubricating oil decreases in this area, problems such as clogging of the pipes are less likely to occur.
the lubricant supply nozzle is provided with a cooling function of the lubricating emulsion and the lubricating emulsion emulsion is injected and mixed after being cooled to not less than 0 ° C. but no longer than 25 ° C. (mixing mode (i) above) and preferably not more than 15 ° C.
the lubricant supply nozzle is provided with a cooling function of the lubricating emulsion, which is emulsified with water having a temperature between 15 and 25 ° C, which provides to the rolling rolls after being cooled to a temperature between 0 and 55 0 C (mixing mode (i) above).
the temperature of the lubricating emulsion it is necessary to maintain the temperature of the lubricating emulsion at more than 0 ° C. This is because, if the temperature of the lubricating emulsion is less than 0 ° C., the water contained in the The emulsion freezes and it becomes difficult to supply the lubricant in the required amount to the mill in a stable manner.
a lubricating emulsion was injected and supplied under the conditions indicated below, to test pieces in the form of plates, which were prepared from a rolled material; the lubricating oil mass adhering to the surface of the plate was measured and the effect of the temperature of the lubricating emulsion on the adhesion efficiency was examined.
Lubricating oil a commercially available hot rolling lubricating oil, viscosity of 120 cSt (40 ° C) o Concentration of the emulsion: 0.5% by volume o Nozzle: flat cone type, available commercially o Supply flow: 500 cm 3 / minute o Supply pressure: 0.15 MPa (immediately before injection from the nozzle) o Feed time: 60 seconds o Test piece: Material in high-speed steel for hot rolling, 100 mm wide X 1 mm thick X 100 mm long
the amount of adhering lubricating oil can be considerably increased by adjusting the temperature of the lubricating oil to not less than 0 ° C., but no more than 25 ° C. Therefore, even if uses the same lubricating oil as is usually used, the lubrication effect can be easily increased by controlling the temperature of the lubricating oil according to the invention.
a strip of material was laminated with a lubricating emulsion supplied to the surfaces of the rolling rolls by controlling its temperature, and using an existing lubricating oil supply piping system. These tests were done to check whether the slippage on engagement in the cylinders or fouling of the pipes took place.
Experimental conditions o Lubricating oil: a commercially available hot rolling lubricating oil, viscosity of 140 cSt (40 ° C.)
O Concentration of the emulsion 0.7% by volume
O Nozzle flat cone type, commercially available
O Feed rate 800 cm 3 / minute
O Feed pressure 0.2 MPa (immediately before injection from the nozzle)
Temperature of the lubricant at the time of injection from the nozzle 0 ° C., 5 ° C., 10 ° C., 15 ° C., 20 ° C., 25 ° C., 30 ° C.
Materials Low steel plate carbon (thickness: 10mm, width: 100mm, length: 300mm) o Laminating speed: 10m / minute o Reduction: 20%
the reduction rate of the rolling force is expressed by assuming that the rolling force at a lubricant temperature of 30 ° C. is 100.
