During the production process of stainless steel precision casting, the sulfuric acid oxide film is an important factor that affects the high purity and transparency of the stainless steel casting oxide film. The porosity, purity, thickness and sealing quality of stainless steel investment casting precision casting will directly interfere with the mirror effect of the casting.
If there are more impurities in the oxide film of stainless steel precision casting, its purity will be low and transparency will decrease. The impurities in the oxide film are mainly derived from the stainless steel casting itself, and part of it comes from the oxidation bath. Therefore, appropriately reducing the content of alloying elements in the casting can minimize the content of impurities.
The equipment required for the basic process of stainless steel investment casting precision casting is: precision casting wax injection-wax injection machine, ice water machine, air conditioner; slurry dipping-slurry bucket, floating sand machine, air conditioner, dewaxing furnace, dehumidifier, dewatering bucket, standing bucket , The dipping slurry can also choose mechanical arm and automatic centralized wax supply system;
Gold melting-sintering furnace, high frequency furnace, shell vibration machine; post-processing-cutting machine, smoothing machine, sandblasting machine, sand cleaning machine, heat treatment furnace, punching machine; maintenance-pneumatic grinder, argon welding machine, smoothing machine; Quality assurance-spectrometer, three-dimensional, etc. These are relatively common and common, if you need more advanced, you also need a vacuum casting furnace or vacuum heat treatment furnace or X-ray and so on.
The output of stainless steel investment casting precision casting cast steel is relatively stable, and the quality, variety, performance and proportion of alloy steel and special steel of steel castings are continuously increasing. Using various refining processes and technologies to develop new cast steel materials can improve the strength and toughness and special properties of the materials.
