Rolling oil online adjustment method based on hot roller system iron sheet classification

Abstract

The invention discloses a rolling oil on-line adjustment method based on hot roller system iron sheet classification, and relates to the technical field of hot rolling surface on-line detection, the method comprises rolling oil opening degree initial value setting, strip steel roller system iron sheet defect collection, rolling oil opening degree calculation logic, and rolling oil use strategy making according to the surface grade measured by a surface instrument. According to the invention, the use of the rolling oil is combined with the defects of the roller system iron sheet detected by thesurface instrument, and the rolling oil is put into use only when the roller system iron sheet appears and meets certain conditions, so that the roll number of the put rolling oil can be greatly reduced, and the consumption of the rolling oil is reduced; the defect grade is determined according to the grade of the strip steel surface roller system iron sheet and the number of defects, online dynamic adjustment of the rolling oil concentration is achieved, and the effect of rolling oil on improving the strip steel surface quality is further achieved. Rolling oil dynamic adjustment is conductedon the basis of the surface quality of a hot-rolled product, so that the rolling oil using efficiency in the hot rolling process is improved, the product quality is improved, and the rolling oil using efficiency is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of on-line detection of hot-rolled surfaces, and more specifically refers to an online adjustment method for rolling oil based on the classification of iron sheets in hot-rolled rolls. Medium rolling oil usage efficiency and improved product quality. Background technique [0002] The flow direction of hot-rolled strip steel is generally divided into: pickling, cold-rolled feed and steel for construction machinery. Except for the slightly lower surface requirements of steel for construction machinery, other products are basically used in fields such as automobiles and home appliances. The surface quality requirements are relatively high, and the surface is not allowed to have obvious roll-type iron sheet pressing defects, otherwise it will seriously affect the user's use. The iron sheet of the roll is a defect caused by the damage of the roll surface. This defect is closely related to the surface quality of ...

Problems solved by technology

[0004] Problems existing in the existing technology: the above-mentioned hot rolling processes such as temperature control, rolling pass, descaling water and load distribution have been solidified in the product design and model, and there is little room for adjustment

The main function of rolling oil as an auxiliary agent in the rolling process is to improve the surface quality of the roll, and then improve the surface quality of the product. At present, it is used in basically all product specifications, and there is a lot of waste. Moreover, the concentration cannot be adjusted after the setting, making the surface When the quality is abnormal, it cannot play a good role in improving

[0005] Patent CN96191202.2 discloses a method for removing scale from hot-rolled steel strips. When hot-rolled steel strips are rolled by cold rolling mills under large rolling reductions, those that cannot keep up with the elongation of the basic steel Cracks and interlayer detachment in the rolled scale, which impairs the adhesion of the rolled scale to the base steel
