The invention relates to the technical field of
metal material
processing, and discloses an automatic
rolling mill roll gap level adjusting method. Pressure measuring heads arranged below the two sides of a
rolling mill are included and used for detecting the rolling pressure and conducting difference value calculation on the detection value, and accordingly, the rolling pressure deviation basis reference is obtained; and the pressure measuring heads are further used for conducting real-time detection on the rolling pressure on the two sides of the
rolling mill when a rolling piece enters thetail throwing stage, difference value calculation is conducted, and the real-time rolling pressure deviation is obtained. According to the automatic rolling mill roll gap level adjusting method, in the rolling piece
tail throwing process, the rolling piece deflection direction is automatically recognized according to the roll gap deviation adjusting amount, the roll gap deviation adjusting amountis transmitted to an AGC
control system, the roll gap deviation AGC cylinder stretching-out amount is added on the basis of the original AGC cylinder stretching-out amount, accordingly,
automatic control over deflection in the rolling piece
tail throwing process is achieved, rolling breakage,
tail throwing, rolling waste and other accidents caused by rolling piece deflection are reduced, the operation rate of the rolling mill is increased, meanwhile, the yield of a rolling line is increased, and the production cost is greatly reduced.
