1.操纵加温温度
1. operating heating temperature
在开展热处理工艺时若是不能准确操纵加温温度,那麽有可能会造成模具钢材内部存有内应力和机构内应力。这类内部内应力的出现会造成淬火时加温温度过高,进而造成淬火裂纹状况的发生,因而cr8模具钢加工厂家在开展钢热处理工艺时尽量减少加温温度过高。
If the heating temperature cannot be accurately controlled during the heat treatment process, there may be internal stress in the die steel and internal stress in the mechanism. The appearance of such internal stress will cause the heating temperature to be too high during quenching, which will lead to the occurrence of quenching cracks. Therefore, CR8 die steel manufacturers try to reduce the heating temperature to be too high when carrying out the steel heat treatment process.
2.严苛把控冷却的时间
2. strictly control the cooling time
据冷作模具钢生产厂家研究表明严苛把控冷却的时间针对减少淬火裂纹或是十分有优势的。在淬火冷却时,若是冷却过度心浮气躁没有把控准确的时间,那麽也有很有可能造成钢内部的内应力随外部的温度产生变化,进而促进淬火裂纹状况经常产生。
According to the research of cold working die steel manufacturers, it is very advantageous to strictly control the cooling time to reduce quenching cracks. During quenching and cooling, if the cooling time is not controlled accurately due to excessive impulsivity, it is also likely to cause the internal stress of the steel to change with the external temperature, thus promoting the frequent occurrence of quenching cracks.
3.严苛把控淬火后的回火
3. tempering after severe control quenching
热作模具钢供应商提议在开展2344钢热处理工艺时要严苛把控淬火后的回火。由于生产加工的零件若是淬火后回火不够或是将来及回火,那麽也有很有可能造成一部分零件的部分产生内应力,这类内应力的发生可能伴随着冷却速率、冷却方法再次产生变化,因而为了更好地减少零件加工时发生淬火裂纹,零件在淬火后应按规范水平立即回火。既可做为注塑模具,也可做为冷工专用工具运用,许多人们在关注“哪有好的2344模具钢材”的与此同时,也十分关注2344热处理工艺时发生的淬火裂纹状况。据科学研究确认根据操纵加温温度、严苛把控冷却的时间及严苛把控淬火后的回火等对策可合理减少淬火裂纹状况
The supplier of hot work die steel proposes to strictly control the tempering after quenching when carrying out the heat treatment process of 2344 steel. If the tempered parts after quenching are not enough or will not be tempered in the future, it is likely to cause internal stress in some parts of the parts. The occurrence of such internal stress may change again with the cooling rate and cooling method. Therefore, in order to better reduce quenching cracks during part processing, the parts should be tempered immediately after quenching according to the standard level. It can be used not only as injection mold, but also as special tools for cold work. Many people are paying attention to "where is a good 2344 mold steel". At the same time, they are also very concerned about the quenching cracks during 2344 heat treatment process. According to scientific research, it is confirmed that the quenching cracks can be reasonably reduced according to the control heating temperature, the time of severe controlled cooling and the tempering after severe controlled quenching
