大宽厚比连续挤压Cu带坯板型的控制

Size Control of Copper Strip Flatness with High Width-thickness Ratio in Continuous Extrusion

研究了大宽厚比连续挤压Cu带坯板型的控制。通过对工装模具、挤压通道等设计和优化,使得大宽厚比Cu带坯连续挤压板型得到了有效控制,满足了连续挤压Cu带坯不铣面直接冷轧的要求。

Flatness control of copper strip with high width-thickness ratio during continuous extrusion was analyzed. Through design and optimization of mould and the extrusion channel, copper continuous extrusion strip is control effectively, which can realize directly cold rolling without scalping.
