Abstract
PURPOSE:To obtain a three-staged rolling mill capable of controlling shape by small numbers of rolls by providing an upper and lower working rolls bending machine and by providing the upper reinforcing roll exchangeably according to the width of plate. CONSTITUTION:The diameter of the upper working roll 1 of the three-staged rolling mill is made smaller than that of the lower working roll 2, and the diameter of the upper reinforcing roll 8 is also made larger than that of the upper working roll 1. And, the diameter of the upper reinforcing roll 8 is made the same as that of the lower working roll 2, and furthermore the acting point of pressure load is regulated according to the surface length LB as a skirted roll. The reinforcing roll 8 is exchanged according to the plate width of the rolling metal 7 for making optimum shape control. Each of the both working rolls 1 and 2 is provided with the benders 12 and 13 to control effectively the plate crown. Thus, it is possible to roll good quality rolling metals with inexpensive rolling mill.
