The technology of mould steel for online pre-hardening

摘要：

This article describes a production method of mould steel pre-hardening, and focus on the advantage of this method ,The technical core of method is the variable frequency and variable amplitude pulse uniform high-precision temperature control, which achieved by using strong-medium-weak water cooling, gas-water cooling and gas mist cooling composite cooling control technology. Optimizing the cooling rate path is a good method of optimizing quenched organization and structure.
