Abstract The wear situation on copper plate lower side was heavy serious in one domestic CCM mould. After the amount of casting steel was only 30，000 ton through wide and narrow copper plates， the copper material had emerged because of the coating on copper plate completely wearing out. After analysis on wear situation and mould structure， some measures can be adopted to improve the wearing problem obviously， for example， to increase the strength of coating material， such as using Ni - Co high-resistant coating material and optimize the alignment between copper plate and rollers and aligning in rollers assembly， optimize the structure of narrow copper plates， which will promote the CCM productivity and enterprise economic benefit.
