Title: Method for deciding amount of axial shift in 4-roll rolling mill
Inventor: KANO AKIRA
IPC: B21B31/16
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To provide a method for deciding the optimum amount of axis shift in a 4-roll rolling mill for enabling highly accurate sizing rolling of a round bar material is enabled. SOLUTION: In the 4-roll rolling of the round bar material, the upper limit of the amount L of axial shift in the rolling direction of nondriven rolls 1C, 1D to the driving rolls 1A, 1B of a 1st stand is set so that the value of the increment ΔT of rolling torque which is increased in accordance with the increase of the amount L of axial shift becomes 10-20% of the difference ΔTm between rolling torques at the time of 2-roll/2-stand rolling and at the time of 4-roll rolling without axial shift. Or, the upper limit is set so that the rolling load of the driving roll that is changed in accordance with the amount of axial shift is minimum. Like this, by setting the amount of axial shift based on the rolling torque or rolling load which is easily measured, the round bar material good in the accuracy of sizing is greatly efficiently manufactured.
