Prevention of stomata in Precision Steel Castings

Precision steel casting, because of their strong wear resistance and good corrosion resistance, do not need to worry about the performance problems at all when they are in use, but there will also be some problems when such steel casting are used, especially some steel casting are prone to stomata, so for enterprises in need, corresponding preventive work should be done to ensure the quality of this part.

 

Today's precision steel casting, the reason for the occurrence of stomata, mainly because of these major reasons. First of all, it is because in the production, the combustion is not enough, resulting in a large amount of gas during pouring, which will lead to no way to discharge the gas, but it will lead to the invasion of liquid and the emergence of stomata. In addition, there is its own material, the quality is not up to standard, especially leading to the gas can not be discharged, it will lead to the generation and formation of stomata.

 

If we want to avoid the occurrence of stomata in the production of precision steel casting, we still need to do a good job of prevention. In general, if conditions permit, we must pay attention to adding exhaust holes in some parts with more complex mechanisms, which can be conducive to the discharge of gas, especially if we need to pour this part, we still need to consider whether exhaust is needed, and we should pay attention to taking into account the combustion temperature, it must be sufficient to avoid the emergence of gas.

 

The current precision steel casting have been well applied because of their good performance, but if you want to avoid pores, you must do the corresponding prevention work. Only in this way can the quality of this part be guaranteed.
