One of the greatest contributors to non-uniform hardness, increased thermal stresses, cracking and distortion is non-uniform fluid flow throughout the quench zone in production quench tanks.
造成淬火后工件硬度不均匀、热应力增加、畸变和开裂，主要是因为淬火槽内整个淬火区的液流不均匀。

The process has low cost, simple operation, high thermal efficiency. It can be achieved that parts or components partially quench, and the high performance surface of material is obtain.
