Cold rolling treatment device for high-quality steel preparation

Abstract

The invention relates to the technical field of cold rolling treatment equipment, in particular to a cold rolling treatment device for high-quality steel preparation. A cold rolling treatment device for high-quality steel preparation comprises a machine base, a roll bearing mechanism is rotationally connected between the inner surfaces of the machine base, a cold-rolled steel strip is wound on the surface of the roll bearing mechanism, a dust suction hood, a servo motor and a top frame are fixedly installed on the surface of the machine base, and a rotating shaft is rotationally connected to the inner wall of the dust suction hood; a set of exhaust fans are fixedly installed on the circumferential side face of the rotating shaft, the output shaft end of the servo motor is in transmission connection with the roll bearing mechanism through a chain a, two sets of vertically-arranged elastic pressure exerting pieces are installed on the inner wall of the top frame, and the bottom face of the top frame is connected with a liquid coating mechanism through the two sets of elastic pressure exerting pieces. The device has the beneficial effects that through the design of the wall cleaning mechanism and the liquid coating mechanism, the device can efficiently complete rolling, cleaning and surface anti-oxidation treatment operation in the cold-rolled steel strip treatment process in an automatic mode.

Description

technical field [0001] The invention relates to the technical field of cold rolling treatment equipment, in particular to a cold rolling treatment device for the preparation of high-quality steel. Background technique [0002] Cold rolling, using hot-rolled steel coil as raw material, pickling to remove oxide scale and then cold rolling, the finished product is a hard-rolled coil, and the cold work hardening caused by continuous cold deformation increases the strength, hardness and toughness of hard-rolled coil The plastic index decreases, so the stamping performance will deteriorate, and it can only be used for parts with simple deformation. [0003] Cold-rolled raw coils are relatively brittle and hard, and are not suitable for processing, so usually cold-rolled steel sheets are required to be annealed, pickled and surface smoothed before handing over to customers. The thickness of the cold-rolled steel plate is below 4.5MM; the minimum thickness and width are determined ...
