1. operating heating temperature

在開展熱處理工藝時若是不能準確操縱加溫溫度，那麼有可能會造成模具鋼材內(nèi)部存有內(nèi)應(yīng)力和機構(gòu)內(nèi)應(yīng)力。這類內(nèi)部內(nèi)應(yīng)力的出現(xiàn)會造成淬火時加溫溫度過高，進而造成淬火裂紋狀況的發(fā)生，因而cr8模具鋼加工廠家在開展鋼熱處理工藝時盡量減少加溫溫度過高。

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.嚴苛把控冷卻的時間

2. strictly control the cooling time

據(jù)冷作模具鋼生產(chǎn)廠家研究表明嚴苛把控冷卻的時間針對減少淬火裂紋或是十分有優(yōu)勢的。在淬火冷卻時，若是冷卻過度心浮氣躁沒有把控準確的時間，那麼也有很有可能造成鋼內(nèi)部的內(nèi)應(yīng)力隨外部的溫度產(chǎn)生變化，進而促進淬火裂紋狀況經(jīng)常產(chǎn)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.嚴苛把控淬火后的回火

3. tempering after severe control quenching

熱作模具鋼供應(yīng)商提議在開展2344鋼熱處理工藝時要嚴苛把控淬火后的回火。由于生產(chǎn)加工的零件若是淬火后回火不夠或是將來及回火，那麼也有很有可能造成一部分零件的部分產(chǎn)生內(nèi)應(yīng)力，這類內(nèi)應(yīng)力的發(fā)生可能伴隨著冷卻速率、冷卻方法再次產(chǎn)生變化，因而為了更好地減少零件加工時發(fā)生淬火裂紋，零件在淬火后應(yīng)按規(guī)范水平立即回火。既可做為注塑模具，也可做為冷工專用工具運用，許多人們在關(guān)注“哪有好的2344模具鋼材”的與此同時，也十分關(guān)注2344熱處理工藝時發(fā)生的淬火裂紋狀況。據(jù)科學(xué)研究確認根據(jù)操縱加溫溫度、嚴苛把控冷卻的時間及嚴苛把控淬火后的回火等對策可合理減少淬火裂紋狀況

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
