Problems solved by technology

But at present, most of the coatings on the surface of the crystallizer are coatings with uniform performance. Even if the upper and lower parts are separated by electroplating technology, the entire production process will be long, complicated and cumbersome, and the production efficiency will be low. Moreover, if the cleaning is not clean, it will directly affect the electroplating layer on the copper plate surface of the crystallizer. It is easy to cause the electroplating layer on the upper area of ​​the copper plate of the crystallizer to fall off, burnt, etc., resulting in a large waste of production costs and affecting the continuous casting production efficiency of steelmaking production

Abstract

The invention belongs to the technical field of surface treatment for a continuous casting crystallizer copper plate. The invention discloses an electroplating method of a continuous casting crystallizer copper plate heterogeneous alloy plating layer, the step is as follows: first, the surface of the continuous casting crystallizer copper plate is preprocessed before plating, then comprehensive electroplating is performed under set technological conditions, when the thickness of the upper plating layer of the copper plate meets the process requirements, a liquid level sensor in a electroplating bath and a PLC servo control system control the electroplating liquid level to drop to a set position, the lower plating layer of the copper plate is electroplated, alloy elements are added into the electroplating liquid, and when the thickness of the lower plating layer meets the process requirements, the electroplating is stopped. According to the electroplating method, plating layers with different thickness and different properties can be flexibly obtained in different horizontal positions of the continuous casting crystallizer copper plate, the material waste can be reduced effectively, the intermediate production process can be eliminated, the production cycle can be shortened, the crystallizer service life and continuous casting efficiency and product quality can be improved.

Description

Technical field [0001] The invention belongs to the technical field of surface treatment methods for continuous casting mold copper plates, and particularly relates to an electroplating method for non-uniform alloy plating of continuous casting mold copper plates. Background technique [0002] As the heart equipment of continuous casting production, the quality of the mold directly affects the quality and operation rate of the slab produced by continuous casting. During continuous casting production, the upper area of ​​the inner surface of the mold copper plate is in direct contact with high-temperature boiling molten steel and molten mold powder. The surface of the sink is cooled by strong cooling water. During casting, the upper surface of the mold copper plate at the molten steel surface is exposed to high-temperature molten steel. Under such an environment, the upper coating of the mold copper plate is required to have good toughness, and have good thermal fatigue resistance...
