In the production process of stainless steel precision casting, the sulfuric acid oxide film is an important factor affecting the high purity and transparency of the stainless steel casting oxide film. The porosity, purity, thickness and sealing quality of stainless steel precision casting will directly interfere with the mirror effect of the casting.
If there are more impurities in the oxide film in stainless steel precision casting, its purity will be low and the transparency will decrease. The impurities in the oxide film mainly come from the stainless steel casting itself, and part of it comes from the oxidation bath. Therefore, by appropriately reducing the content of alloying elements in the casting, the impurity content can be reduced as much as possible.
The equipment required for the basic process of stainless steel precision casting is: precision casting wax injection-wax injection machine, ice water machine, air conditioner; dipping-slurry barrel, floating sand machine, air conditioner, dewaxing furnace, dehumidifier, water removal barrel, static barrel , the dipping can also choose a mechanical arm and an automatic centralized wax supply system;
Finance - sintering furnace, high-frequency furnace, shell shaker; post-processing - cutting machine, grinding machine, sandblasting machine, sand cleaning machine, heat treatment furnace, punching machine; maintenance - pneumatic grinding machine, argon welding machine, grinding machine; Quality Assurance - Spectrometer, 3D, etc. These are relatively common, and if you need more advanced ones, you also need a vacuum casting furnace or a vacuum heat treatment furnace or X-ray and so on.
The output of stainless steel precision casting is relatively stable, and the quality, variety, performance of steel castings, and the proportion of alloy steel and special steel continue to increase. Using various refining processes and technologies to develop new cast steel materials can improve the strength, toughness and special properties of the materials.
