- 结晶器铜板作为连铸设备的关键备件，在使用过程中会出现热裂纹、磨损、腐蚀等问题，因此结晶器铜板需通过表面处理以提高其耐高温、耐磨损、耐腐蚀性能。本文结合其主要失效形式总结论述了连铸结晶器铜板近几年的电镀技术生产实践，主要包括电镀前处理技术、电镀非均一性镍硼合金和电镀镍基陶瓷复合镀技术生产实践。电解刻蚀前处理技术能有效提高铜板表面粗糙度并进一步提高镀层与基体的结合强度，镍硼合金生产实践表明通过控制合适的工艺能够制造出硬度梯度较大的镀层，复合镀生产实践表明能够在铜板表面制造出镍基复合镀层，但陶瓷颗粒的加入对电镀设备连续性有一定影响。
- Abstract:
- As a key spare part of continuous casting equipment ， the mold copper plate will appear hot crack ， wear ， corrosion and other problems in the use process ， so the mold copper plate needs surface treatment to improve its high temperature resistance ， wear resistance and corrosion resistance. In this paper ， the production practices of electroplating technology for copper plate of continuous casting mould in recent years were summarized and discussed combined with the main failure modes ， including electroplating pretreatment technology ， electroplating non-uniform Ni-B alloy and electroplating nickel-based ceramic composite plating technology. Electrolytic etching pretreatment technology could effectively improve the surface roughness of copper plate and further improved the bonding strength between the coatings and substrates. The production practice of Ni-B alloy showed that the coating with larger hardness gradient could be produced by controlling the appropriate process. The production practice of composite plating showed that nickel-based composite coatings could be produced on the surface of copper plate ， but the addition of ceramic particles had a certain impact on the continuity of electroplating equipment.
