The quenching frame is a tool used in the heat treatment process, mainly to hold and transport workpieces. The quenching material frame is usually made of heat-resistant, corrosion-resistant materials, such as stainless steel, carbon steel, etc. Its shape and size are determined according to different uses and process requirements, and generally have good rigidity and durability.
In the heat treatment process, quenching frames are used to place workpieces that need to be heated, insulated, and cooled. The workpiece can be quickly and uniformly heat treated in the quenched material frame to improve the performance and quality of the workpiece. The design and use of quenching frames has a significant impact on the efficiency of the heat treatment process and the quality of the workpiece.
In addition, the use of quenching frames can simplify the production process, improve production efficiency, and reduce damage and deformation of the workpiece during processing. At the same time, the quenching frame can also protect the workpiece from oxidation, contamination and breakage, and improve the service life and reliability of the workpiece.
Therefore, the quenching frame is one of the indispensable tools in the heat treatment process, and its quality and performance have an important impact on the smooth progress of the heat treatment process and the quality of the workpiece.
