Combination screw-down system for rolling mill

Abstract

A combined press-down system of rolling mill for improving the rigidity of whole rolling mill is composed of the vertically and symmetrically arranged upper and lower pressing cover bodies with two arc slots on each of their opposite inner surfaces, a press-down mechanism above said upper cover body, the bushes inlaid in said arc slots, upper and lower supporting rollers, and the supporting modules between said bush and supporting roller and consisting of multiple supporting axles, multiple guide rollers and one locating roller.

Description

(1) Technical field [0001] The invention relates to a rolling mill, in particular to a combined pressing system of the rolling mill. (2) Background technology [0002] The pressing mechanism and roll support system are commonly used devices in steel rolling processing equipment. The conventional pressing mechanism acts on the bearing seat on the roll neck, the roll surface cannot be effectively supported, and the roll bends when the roll is stressed. , due to the deflection of the roll, the extension along the strip cross-section during the rolling process is uneven, which deteriorates the flatness of the strip, which brings great problems to the production of high-precision strips. Now solve these The methods to solve the problem are all focused on increasing the diameter of the backup roll, presetting the roll shape, bending the work roll, and stringing the work roll. Although these methods can correct the plate shape to a certain extent, they add a certain amount to produ...

Now solve these The methods to solve the problem are all focused on increasing the diameter of the backup roll, presetting the roll shape, bending the work roll, and stringing the work roll. Although these methods can correct the plate shape to a certain extent, they add a certain amount to production. The difficulty, but also greatly increased the investment in equipment
