热锻模是模锻生产的主要工具。在模锻件生产中,锻模费用所占比例很大,如要降低模锻件成本,就得提高热锻模寿命。影响热锻模寿命因素较多,如:材料选择、锻模的设计、冷热加工质量、锻造工艺以及操作使用等,而热处理质量是锻模寿命高低的关键工序之一。因此,提高锻模热处理质量有着极其重要的意义。热锻模常用材料为5CrNiMo或5CrMnMo钢,一般热处理工艺是加热到淬火温度后,保温一定的时间,出炉后在空中预冷到760～780℃入油冷
Hot forging die is forging production of the main tools. In forging production, the cost of forging a large proportion, if you want to reduce the cost of forging, you have to increase the life of hot forging die. Affect the hot die life of many factors, such as: choice of materials, forging die design, hot and cold processing quality, forging process and operation, etc., and heat treatment quality is one of the key stages of die life. Therefore, improving the quality of forging heat treatment is extremely important. Common materials for hot forging die 5CrNiMo or 5CrMnMo steel, the general heat treatment process is heated to quenching temperature, heat a certain time, baked in the air precooling to 760 ~ 780 ℃ into the oil-cooled
