The sulfuric oxide film of stainless steel precision casting is an important factor to influence the high purity and transparency of the oxide film of stainless steel castings. The porosity, purity, thickness and sealing quality of stainless steel precision casting can directly interfere with the mirror effect of casting.

Stainless steel precision casting in the oxide film contains more impurities, its purity is low, transparency will be reduced.

The impurity in the oxide film is mainly result from stainless steel castings, and part of the bath is derived from the oxidation and therefore appropriate to reduce the content of alloy element in casting, you can try to reduce the impurity content.

The equipment required for the basic process of stainless steel precision casting is:

Precision casting wax - jet wax machine, ice water machine, air conditioning; Slurry - slurry bucket, float sand machine, air conditioning, dewaxing furnace, dehumidifier, dehumidifier, bucket and static barrel, the pulp can also choose the mechanical arm and automatic concentration for the wax system; These are common and common, and if more advanced, vacuum casting furnaces or vacuum heat treatment furnaces or x-rays are required.

The steel production of stainless steel precision casting is relatively stable, and the quality, variety, performance and proportion of alloy steel and special steel are constantly improved. With various refining techniques and techniques, the development of new cast steel materials can improve the toughness and special properties of the materials.
