Description of the invention: [Technical field to which the invention pertains] This document is a hot rolling method for hot rolling oil for steel and steel. In particular, the steel is heated in the range of 200 to 12 〇 (the range of rc and hot-rolled processing is performed), so that the coefficient of friction between the roller and the steel is the same as or higher than that in the case of no oil supply, and the heat of the steel can be reduced by the low pressure of the yak. Hot rolling method for rolling oil and steel. [Prior Art] In recent years, carbon steel, stainless steel, tool steel, steel and other steel materials are introduced; μ calendering or hot pressing delay, in order to prevent the surface of the roller from being rough, the system is used high. Use / slick to obtain the effect. As a lubricant, it is generally used for: graphite, glass, boron nitride, mica bismuth molybdenum oxide, fluorinated graphite, carbonic acid, etc. Solid lubricants; petrochemical oils, sulfurized olefins, zinc dialkyl dithiophosphates 0 丨 〇 〇 、 、, scallops and other extremely waste lubricants; mineral oil, oil: substances: synthetic esters and other oily improvement Adhesive improver such as methacrylate copolymer 5, butyl-thin composite, and a reduced-point-down meal may be added alone or in combination of 2 or more types, and bis-cresol or cresol may be added as needed. Antioxidants such as α-naphthylamine. So high The use of lubricants, in the hot rolling of steel, has the effect of reducing the coefficient of friction between Ma Yan's light shoulders and the building's length. ς ς ς 延 间 间 # # # # # # # # # # # # # # # # When the hand 'coefficient' is used in the calender to produce the same material, the calendering load can be reduced and the force is increased. Therefore, the contact pressure between the rolled material and the material is suppressed (the surface of the material is called _ _ 319879 5 200844220 'The skin of the sex is rough and maintains good fortune... Table • The surface quality of the rolled steel is a good two surface, which can be used to press the powerfully sprayed cooling water to flow the flow. However, because it is Effectively attached to the surface of the roller. It is difficult for the hot rolling oil to prevent the influence of the cooling water. The water removal plate is provided with water removal prevention on the Li Kun cylinder of the work roll. Fortunately, the Kunming cylinder cooling water flows into the nozzle to shoot the oily night === contact, in the general oil supply method of hot rolling oil = the same surface. That is, the water film of the cooling water of the water board is removed::, oil mode 'With the work roll sprayed calendered oil emulsion secret', in order to make the work roll Condition. However, in the high-speed rotation work on the surface of the lucky cylinder, the water removal board and the work roll:: The water removal board is difficult to completely form the surface of the working light cylinder =, light cooling water Report II is owed, all, and L, so that the adhesion of the rolling oil C can not achieve sufficient 昼 load reduction effect. Another - square two in the heat = oil, although there is also spray to the support light tube (ba =: but with Compared with the case where the oil is supplied to the work roll, since the calendered oil is interposed between the workpieces on the same surface of the roll, the effect of the same on the surface of the roll of the iron I 乍矣b reaches the roll and the calendering effect is poor.

On the other hand, there is a hot rolling method in which a lubricant is supplied to each of the work rolls and the support rolls in a non-stop pressure-delay manner (Patent Document 5), on the respective surfaces of the upper and lower support rolls and the upper and lower support rolls.
