Abstract

The invention discloses reversible cold-rolling equipment, which comprises a main rolling mill, and a front tension device (9), a front alignment device (8), a rear tension device (11) and a rear alignment device (12) positioned on front and rear sides of the main rolling mill. The middle roll of the eight-roll rolling mill is a transmission roll, the transmission side of two lower supporting rolls (10-7) is provided with a lower rolling wire adjusting device connected with an eccentric shaft thereof, and the lower rolling wire adjusting device comprises a box body (20), a driving mechanism and two sets of worm gear transmission mechanisms placed in the box body. The invention also discloses a production method for the reversible cold-rolling equipment, which comprises working roll opening adjustment before rolling, low-speed direct bite of a to-be-rolled strip steel head, high-speed rolling operation and tensioned low-speed rolling operation of a to-be-rolled strip steel tail. The method can meet the bite condition of the rolling mill, realizes a reversible cold-rolling process without leading strip, has high rolling stability and high production efficiency, and is particularly suitable for reversibly cold-rolling thin specification strip steels.

Description

technical field

[0001] The invention relates to a reversible cold-rolling equipment, in particular to a reversible cold-rolling equipment for cold-rolling strip steel and a production method thereof. Background technique

[0002] The existing reversible cold rolling equipment consists of main rolling mill and uncoiler, straight head straightening machine, coiler, steering device, hydraulic shear, thickness gauge, degreasing device, tension roller device, centering device, feeding roller Auxiliary equipment such as guide plates, lubrication, hydraulic pressure, degreasing and other auxiliary equipment connected to these equipments and their electrical control systems. Wherein: the main rolling mill is a four-high rolling mill or a six-high rolling mill, and the tension device and centering device are arranged on the front side of the main rolling mill. The biggest disadvantage of this reversible cold rolling equipment is low yield and high energy consumption. Among them: th...
