带槽轧辊真空密封造型铸造成型工艺

Casting forming of shaped roll with vacuum sealed mould

概述了带槽轧辊的制造工艺 ,提出了带槽轧辊真空密封造型铸造成型新工艺 (V法 ) ,介绍了V法工艺数值模拟软件的特点及功能 ,并通过试验证明了该工艺的可行性 ,及成型的带槽轧辊具有尺寸准确 ,表面光洁、无裂纹 ,轧槽工作面硬度高等优点。

The forming processes of shaped roll are briefly introduced, and a new casting process with vacuum sealed mould is proposed. The feasibility of the process has been invesigated through numerical simulation and experiments.
