Cooling Process of Die Steel during On-Line Pre-Hardening

Abstract:

Pre-hardening plastic die steel can be directly processed into the mold, and it doesnt need quenching and tempering again, which avoids quenching deformation and ensures the size precision of the mold. On-line quenching of die steel can shorten the production cycle, and it has the advantage of energy saving. In the paper, a new on-line quenching device was introduced, and the temperature field calculation model of 3Cr2NiMo die steel was established. The cooling technology of three typical thickness steel plates was studied. The results provided the theoretical basis for die steel production.
