Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to a preparation method of a continuous casting roller crystallizer. Background technique [0002] Thin strip continuous casting technology is a cutting-edge technology in the field of metallurgy and material research, which has changed the production process of thin steel in the traditional metallurgical industry. The thin strip continuous casting technology is adopted, which integrates continuous casting, rolling, and even heat treatment, so that the thin strip produced can be formed into industrial products at one time after a little cold rolling, which simplifies the production process and shortens the production cycle. Line length is only 60m. Its appearance is bringing a revolution to the steel industry. [0003] According to the different crystallizers, the thin strip continuous casting technology can be divided into belt type, roll type, roll belt type, etc. Among t...
