Title: Set-up method of rolling mill
Inventor: NAKANISHI TOSHINAGA
IPC: B21B37/00
Filed: 1982-08-31
Abstract: PURPOSE:To set up a roll with an accurate adjustment immediately when a rolling speed or roll diameter changes by establishing an equation for calculating the eoefft. of friction having versatility in cold rolling and predicting rolling characteristics by using said equation. CONSTITUTION:It is a known fact that the coefft. of friction between a cold rolling roll and a material to be rolled decreases with and increase in a roll diameter and rolling speed. The coefft. of friction mu is expressed by the equation  I where the constants determined by a rolling mill oil and roll surface are designated as a1, a2, the reference values of a work roll diameter and roll speed as DO, DRO, and the actual values of a work roll diameter and roll speed as D, VR. The coefft. of friction mu is incorporated into the known calculation equation, by which the rolling load, rolling torque, power and forward slip are calculated. The accuracy in the forward slip is improved by about 2% error in a mass flow ratio if the conditions are set in the above-mentioned way. A calculation for correct adjustment are made possible even when the roll diameter changes and therefore the accuracy of products and working efficiency are improved.
