摘要： PURPOSE:To increase the amt. of a lubricating oil to a contact part and to permit high-speed and high-draft rolling by subjecting a hard-to-work material to rolling at a prescribed draft with rolls having prescribed roughness, then to ordinary rolling with rolls having small roughness. CONSTITUTION:The hard-to-work material which consists of stainless steels, titanium, titanium alloy, etc., and is descaled is subjected to rolling at 1-5% draft by the dull rolls 1 having 0.5-2.0mum surface roughness Ra in the first one pass at the time of cold working said material. Roughness is imparted to the surface of the rolled stock 2 by such rolling, by which the amt. of the lubricating agent to be introduced to a roll bite is increased. The rolled stock is then subjected to ordinary rolling by the bright rolls having

摘要： PURPOSE:To stably manufacture a stainless steel strip having good surface quality by hot rolling a stock by supplying a dispersion liquid, whose friction coefficient is adjusted by addition of iron oxide, etc., onto the surface of a rolling roll in a position corresponding to the strip edge rolling part. CONSTITUTION:At the time of hot rolling a stainless steel strip, a dispersion liquid whose friction coefficient is adjusted to be 0.2-0.4 by addition of >=1vol% of >=1 kind of iron oxide, silica, and alumina is supplied onto the surface of a rolling roll in a position corresponding to the strip edge at least. In that situation, continuous rolling does not cause insufficient biting or slips and stainless steel stips having the good surface quality are stably manufactured without generation of seizing flaws.

摘要： PURPOSE:To prevent slip between rolls during accelerated and decelerated rolling and to enable the rolling mill to make stationary rolling at a high speed and high draft by controlling the supply rate of a rolling mill lubricant so as to increase or decrease said rate according to the rolling speed. CONSTITUTION:The rolling speed is detected by a tachometer 3 connected to a roll driving motor 2 of a rolling mill 1 of a backup roll driving system. The supply rate of the rolling mill lubricant discharged from a feed pump 5 for the rolling mill lubricant is controlled by a speed control device 4 of the pump 5 and the rolling mill lubricant is injected to the mill 1 and a strip 9 from nozzles 8. The strip is thus rolled without generation of a slip owing to the excessive lubrication during accelerated and decelerated rolling and a heat scratch owing to the deficient lubrication in the stationary rolling stage at a high speed.

摘要： PURPOSE:To enhance the cleaning effect of hot water, to apply an evaporation promotor, and to lower its consumption amount, by mixing a rolling oil-evaporation promotor into hot water to be injected under a pressure onto a thin steel sheet near the final rolling stand of a continuous cold rolling mill. CONSTITUTION:The thin steel sheet 2 is rolled by a five-stand tandem mill, for instance, using a rolling oil composed of mineral oil and about 20% beef tallow in its first to fourth stands. Between the fourth and fifth stands, washing water 3 kept at a temperature of about 50 deg.C under a pressure of about 100kg/cm and containing an evaporation promotor (a special high molecular compound: polyisobutylene having a molecular weight of 10,000) is injected onto the steel sheet 2, to diminish the rolling oil and iron powder adhered onto the steel sheet 2 and to apply the evaporation promotor onto the steel sheet 2. Thereafter, the steel sheet 2 is carried to an annealing step. In this case, the running speed of the sheet 2 at the fifth stand is about 1,000m/min, the residual adhesion amount of the rolling oil between the fourth and fifth stands after washed is about 25mg/m , and the apply amount of the evaporation promotor at the fifth stand is about 15mg/m .

摘要： PURPOSE:To enable annealing without undergoing cleaning and provide the clean surfaces free from carbon stains by coating the material which exhibits a minimum azeotropic phenomenon with the rolling oil deposited on steel plate surfaces and annealing the steel plate. CONSTITUTION:The material which exhibits a minimum azerotropic phenomenon with the high-lubricity rolling oil deposited on the surfaces of the steel plate after cold rolling is coated by a ameans such as spray coating provided within the rolling line or in an other simple line and the steel plate is annealed in that state. An azeotropic phenomenon occurs with the high-lubricity rolling oil and coated material in the high-temperature atmosphere during annealing, by which the remaining of the rolling oil on the steel plate surfaces is prevented and the cold rolled steel plate having clean surfaces is obtained. The coating material is at least one kind of hydrocabons, alcohols, ketones, amines, and esters of fatty acids or dibasic acids.
