Rapid pickling device and method for cold-rolled strip steel

Abstract

The rapid pickling device comprises a fixed face, a strip steel raw material, a recycling plate, an unwinding roller set, a winding roller set, a main support, a pickling box, a first baffle and a second baffle, the unwinding roller set, the winding roller set, the main support, the pickling box, the first baffle and the second baffle are arranged on the fixed face, a first motor is arranged on the unwinding roller set, a second motor is arranged on the winding roller set, and a control box and an air cylinder are arranged on the main support. A movable frame is arranged on a telescopic rod of the air cylinder, a pressing roller is arranged on the movable frame, a smooth chamfer and a recycling hole are formed in the pickling box, a flow guide groove is formed in the recycling plate, and an air opening and a drying fan set are arranged on the first baffle. The pickling quality of the part of strip steel raw materials moved to the upper portion of the pickling box is improved, the efficiency is improved through assembly line type pickling, the strip steel raw materials subjected to pickling are comprehensively and effectively dried, the rolling quality of the strip steel raw materials is guaranteed, dripped residual pickling liquid is guided and recycled, and waste of the residual pickling liquid is avoided.

Description

technical field [0001] The invention relates to the technical field of cold-rolled strip steel processing, in particular to a rapid pickling device and method for cold-rolled strip steel. Background technique [0002] Cold-rolled strip refers to hot-rolled strip and steel plate as raw materials, which are rolled into strip and sheet by cold rolling mill at room temperature. The general thickness is 0.1~3mm, and the width is 100~2000mm. Cold-rolled strip or sheet has the advantages of good surface finish, good flatness, high dimensional accuracy and good mechanical properties. Usually the product is in coils, and a large part is processed into coated steel sheet. [0003] Pickling will be carried out before cold-rolling the strip raw material, which can remove the oxide scale on the surface of the strip raw material and ensure the quality of the later cold-rolled strip. [0004] However, the pickling quality and pickling efficiency of the existing pickling device for raw m...

Problems solved by technology

[0005] The purpose of the present invention is to provide a quick pickling device and method for cold-rolled strip steel, so as to solve the problem of the low pickling quality and pickling efficiency in the prior art and the direct winding of strip steel raw materials with pickling liquid remaining on the surface Causes the reduction of winding quality and the inability to divert and recycle the dripping residual pickling solution, resulting in waste
