摘要： PURPOSE:The ingredient of milling oil is examined on specified tests and the results are compared with the calclutation values derived from experimental equations to evaluate correctly the milling oil suitable for cold rolling, thus preventing the heat scartch and increasing the productivity of rolling. CONSTITUTION:The ingredient of milling oil before made into emulsion or obtained by extracting the emulsion is subjected to Bouden test to derive the sliding number until galling occurs n from the relationship between the sliding number and the friction coefficient. Then, the sliding number in is compared with the value derived from the experimental equation satisfying the desired rolling conditions and judged if the oil is suitable as the milling oil.

摘要： PROBLEM TO BE SOLVED: To prevent development of edge cracks, fluctuation of the rolling load, chatter marks, and breakage of steel plates by specifying the temperature of the steel plate on the inlet side of the first pass when a hot rolled austenitic stainless steel plate in which the total draft and the draft of each pass are specified, is cold rolled. SOLUTION: When a hot-rolled austenitic stainless steel plate in which the total draft is >=50%, and the draft of each pass is >=15% is cold rolled, edge cracks and generation of chatter marks of the steel plate during the cold rolling are prevented by controlling the temp. of the steel plate at the inlet side of the first path to 25 to =10% working- induced martensite is generated, and chatter marks are generated. In particular, the fluctuation in load at acceleration/deceleration part, generation of chatter marks, and breakage of the plate can be prevented, and the rolling can be stabilized even when emulsion oil is used, and the rolling is achieved at high rolling speed of >=300 m/min, using reverse type rolling mill during the winter time when the outside temperature is low, and the temperature of the inlet side steel plate is low.

摘要： PROBLEM TO BE SOLVED: To execute high speed rolling of a steel sheet required for high gloss even when a new liquid is supplied to adjust concentration and a liquid level by using a uniform solution prepared through previous addition of a prescribed amount of water to a stock solution of a rolling mill lubricant as the rolling mill lubricant of an oil-in-water type emulsion. SOLUTION: Water of 1-10 vol.% is previously added to the stock solution of a rolling mill lubricant used as an oil-in-water type emulsion to get a uniform solution, then the solution is used as the emulsion of concentration-in-water of 1-10 vol.% and thus cold rolling of a steel sheet is executed at a high speed of >= 400 mpm. Above all, by making the amount of the upper limit of water added to the stock solution of a rolling mill lubricant equal or less than the amount of blending of the emulsion in the stock solution of the rolling mill lubricant, the required time for the particle size of the emulsion to become a stationary state is shortened. Further, when the making-up supply is made after solubilization by previous addition of water to the stock solution of the roling mill lubricant, the average particle size of the oil in the water of emulsion is made into a fine particle size of

摘要： PURPOSE:To obtain the subject product effective for preventing the seizure in hot-rolling, increasing the draft and the rolling speed and enabling the rolling of stainless steel in high efficiency by adding a specific dialkyl polysulfide and a phosphorous acid ester to a base oil. CONSTITUTION:The objective product having a viscosity of 100-500cst at 40 deg.C is produced by compounding (A) a base oil having a molecular weight of >=500 with (B) 20-70wt.% of a dialkyl polysulfide having a sulfur content of >=30wt.% (preferably 6-13C compound) and (C) 3-10wt.% of a phosphorous acid ester (preferably an alkyl phosphite having 6-18C alkyl group). The adjustment of the viscosity of the product is carried out e.g. by using a mineral oil having a molecular weight of 500-1,000 and a synthetic ester having a molecular weight of 724-892 as the base oil and varying the mixing ratio of the components. The product is applied generally at a rate of 0.5-30g/m .
