Abstract: As a key equipment for steel continuous casting,The quality of continuous casting mould greatly affects the process of continuous casting.The copper alloy plate and surface treatment technology are generalized and analyzed.Since narrow copper plate is liable to deforming and wearing at high temperature,high strength and high thermal conduction ODSCu material is introduced to prolong the maintenance period and increase the production efficiency,and new alloy electroplated layer and spray coating are developed to further increase the hardness,wear-resisting and corrosion-resisting property.
