A large forging semi-steel vertical roll heat treatment cooling method

Abstract

The application discloses a large-scale forging semi-steel vertical roll heat treatment cooling method, which comprises the following steps: step one, a rapid cooling stage; step two, a stable cooling stage; step three, a core heat penetration stage; and step four, a temperature homogenization stage. The application has the advantages of simple equipment structure, low cost, simple operation, wide application range, different cooling speeds from air cooling to air cooling to mist cooling, convenient adjustment between different cooling speeds, flexible conversion, different product and cooling speed requirements, and small space requirement. The cooling equipment is used together with the cooling process, so that the cooling intensity can be effectively controlled, the target organization transformation is realized, and the semi-steel vertical roll has excellent mechanical properties and use performance.
