Stainless steel precision casting process is a general term for casting technology. Stainless steel precision casting products have a long service life and are extremely heat resistant, which can effectively avoid the distortion or ripple effects on parts due to high temperatures. So, do you know the reasons for the high carbon content in stainless steel precision castings?
The setting of pouring conditions for stainless steel precision castings is unreasonable: if the pouring and filling process is set too long, it will cause the temperature of the molten steel to be low during the pouring process, especially for the positions where the casting wall thickness increases, the solidification speed of the molten steel will be slow, resulting in a longer liquid-solid residence time, which promotes the reaction time between the molten steel and the thermal decomposition products of the mold, and increases the amount of carburization and carbon deposition in the steel castings.
The setting of the stainless steel precision casting pouring system is unreasonable, especially the configuration of the vacuum pumping system and the pouring sand box or the casting casting casting process modeling is unreasonable, resulting in uneven and excessive deviation of the vacuum degree in the pouring sand box during the casting process, or insufficient actual vacuum degree, while the true vacuum pressure gauge displays incorrect values that meet the technical parameter requirements.
The main reasons for the high carbon content in stainless steel precision castings are the ones mentioned above. The reasons for the high carbon content in our stainless steel precision castings are the ones mentioned above.
