How to adjust the furnace fire for stainless steel casting

Stainless steel casting is a casting method compared to the traditional casting process. It can achieve higher casting precision. The more common method is: first make the grinding tools according to the product specifications, and then cast them by casting. Wax is used to obtain the initial wax model; the process of coating and sanding is repeated on the wax model, the mold shell is solidified and dried; the internal wax mold is then melted to dewax and the concave mold is obtained; the mold shell is fired to obtain sufficient The strength; the metal composite material required for stainless steel casting; the sand is removed after molting to obtain high-precision finished products, and heat treatment and cold processing can be carried out according to the needs of the product. Let’s talk about the casting process of precision castings How to adjust the stove fire.

It is necessary to moderately increase the casting temperature. Although the liquid shrinkage increases after the casting temperature increases, the additional pouring and shrinkage need to be increased, but it is helpful to clean up the slag inclusions and gas ports. The deep adjustment of the three-corner white openings in the casting sequence is very traditional, but it is good. It is practical, convenient, and is very beneficial to the quick identification of technical personnel and workers outside the furnace. If the size of the three-corner white opening is related to the production results, full-phase structure, thermal analysis curves and physical properties, it will be beneficial to cast iron. Online adjustment of quality. Thermal analysis curve analysis, using sequential supercooling ratio adjustment to achieve results. This method has been used in Germany and is related to the metallurgical industry quality standards, eutectic cluster number, and ductility modulus.

In the detection of elastic molds and internal stress; high carbon equivalent, high toughness, high bending stiffness, and low stress are the key requirements for controlling the material of lathe castings. Using a complete set of processes for machine tool casting production can achieve high carbon Equivalent, high toughness, high bending stiffness, low stress quality standards.
