冷模钢实际上是指模具零件的热处理。冷冲裁模、冷扎模、冷挤压模、冷拉深拉模等冷拉模具种类繁多。在形状结构的巨大差异下，操作条件和功能规定也有所不同。除选择合适的数据外，还应选择Z佳的热处理方法，以适应模具的使用，提高磨具的使用寿命。
In practice, cold work die steel refers to the heat treatment of die parts. There are many kinds of cold working dies, mainly including cold blanking die, cold heading die, cold extrusion die, cold drawing die, etc. Due to the great differences in shape and structure, the operating conditions and functional requirements are also different. In addition to selecting suitable materials, we should also select z-best heat treatment process to meet the functional requirements of the die and improve the service life of the die.
球化退火冷加工模具煅烧后，充分准备Z终热处理，清除锻坯的铸造应力，改善显微布局，降低强度，便于加工。
The cold working die needs spheroidizing annealing after forging, cleaning the casting stress of the forging blank, improving the microstructure arrangement and reducing the hardness, so as to facilitate machining and prepare for Z final heat treatment.
淬火是冷加工模具终热处理的主要操作。应注意模具的使用。应注意以下几点：
Quenching is an important operation in the final heat treatment of cold working die. It has a great impact on the use function of the die, which should be paid special attention to. The following points should be noted:
1)应识别磨具数据，并检查磨具表面是否有划痕和裂纹。
1) Acknowledge the mold data and check whether there are scratches, cracks and other defects on the mold surface.
2)根据模具外观，模具文学和武术的趋势可能会导致各种阻塞、相关或绑定，以便均匀地加热和制冷。
2) According to the shape of the mold, estimate the trend of mold literature and martial arts, and make a variety of blocking, binding or binding to make uniform heating and cooling.
3）合理选择淬火加热温度的马氏体，不仅需要与一些合远素和碳固溶，还需要过多的渗碳体来细化晶粒，以保证模具的淬火、硬化水平和强度，提高模具的耐磨性，确保磨具有一定的耐久性。同时，应注意磨具温度对加热环节变形和加热的影响。
3) Reasonable selection of quenching heating temperature austenite not only needs solid solution with some alloying elements and carbon to ensure the hardenability, hardening ability, strength and thermal hardness of the die, but also needs appropriate excess carbide to refine the grain, improve the wear resistance of the die and ensure that the die has certain resistance. At the same time, the influence of mold temperature on deformation and preheating during heating should be considered.
4)合理选择淬火、加热和保温时间-磨具淬火和加热，根据加热设备选择的经验公式换算保温时间。但在具体的热处理操作中，应注意模具零件的实际情况。但在具体的热处理操作中，应注意模具零件的实际情况。但在具体的热处理操作中，应注意模具零件的实际情况。特别是对于复杂的磨具，应充分考虑各种相关因素，并确认淬火和绝缘时间。
4) Reasonable selection of quenching, heating and heat preservation time for the quenching and heating of general molds, the heat preservation time can be calculated according to the experience formula selected by the heating equipment. However, the specific conditions of die parts should be considered in the practical heat treatment operation. Especially for complex molds, various influencing factors should be comprehensively considered, and the quenching and holding time should be confirmed through tests.
