Abstract

Insulation coating can effectively improve the corrosion resistance of silicon steel sheet,such as corrosion,magnetic,insulation performance,thus oriented silicon steel insulation coating is the important part of oriented silicon steel production process.In this paper,the inorganic insulation coating oriented silicon steel containing chromium and chromium nitride coating performance advantages and disadvantages are introduced.In addition,the research status of insulation coating and chromium nitride coating on inorganic chromium oriented silicon steel in China is reviewed.Finally,the future research and development direction of inorganic insulation coating containing chromium is prospected.
