Title: Method for rolling tapered steel plate
Inventor: OTAKE KOICHI
IPC: B21B37/24
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To efficiently execute multipass/taper rolling without bringing damage of equipment by downward camber of the tip and without spoiling the flatness of materials by specifying an approach angle to the top surface of a transporting table for steel plates to a rolling mill. SOLUTION: The approach angle to the rolling mill of materials in the case that the steel plate is bitten from the side of small thickness of the steel plate is calculated by a formula. In the formula, αis the approach angle, (i) is a pass number, S is a separated distance of the upper end of the lower work roll to the top surface of the transporting table at the end of each pass, H is the thickness before rolling in each pass, (h) is thickness after rolling in each pass, (l) is the length of the back surface of the plate before rolling in each pass, appended letters 1, 2 respectively show a thin part and the thick part.  In the pass that the calculated approach angle is smaller than the reference approach angle, rolling is reversely executed while elevating and lowering the lower work roll and, in the pass that conditions are not satisfied, rolling is executed in the ascending direction of the lower work roll.
