Introduction

In the heat treatment process, different cooling methods are used depending on the material type, size, structural characteristics and performance requirements of the workpiece. The steel immersion quenching cooling method is the most widely used, so the heat treatment cooling technology specified in this standard is only for the steel immersion liquid. Quenching and cooling process. The rigor of the formulation and implementation of the quenching and cooling process will directly affect the performance and mass dispersion of the workpiece. Correct selection of quenching cooling Medium, quenching and cooling equipment, quenching fixtures and performing a reasonable quenching and cooling process are prerequisites for the performance of the workpiece, while quenching the cooling medium The composition, concentration, temperature, flow rate and uniformity, as well as the control accuracy of the quenching and cooling process determine the dispersion of the workpiece quality. The implementation of this standard will help to ensure the quenching and cooling quality of the workpiece, reduce the mass dispersion of the batch processing parts and achieve product quality. Traceable. Heat treatment cooling technical requirements

1 Scope
