The main method of stainless steel precision casting mirror treatment effect

The hydrochloric acid oxide film in the whole process of stainless steel precision casting is a key element that harms the sweetness and transparency of the oxide film of stainless steel castings. The porosity, purity, thickness and sealing quality of stainless steel precision casting are all It immediately affects the actual effect of the mirror glass of the casting
If there are more residues in the oxide film in stainless steel precision casting, its purity will be low, and the clarity will be reduced. The residue in the oxide film mainly comes from the stainless steel casting itself, and part of it comes from the oxidation bath. Therefore, moderately reducing the content of aluminum alloy elements in the casting can reduce the residue content as much as possible.
The necessary machinery and equipment for the basic steps of stainless steel precision casting are: high-precision casting wax injection-wax injection machine, industrial chiller, central air conditioning; Plastic buckets, static buckets, and slurry dipping can use robotic arms and fully automatic centralized wax supply system software;
Gold melting-sintering furnace, high frequency furnace, shell vibration machine; post-processing technology-cutting machine, grinding machine, automatic sandblasting machine, sand cleaning machine, heat treatment equipment, high-speed punch; maintenance-pneumatic grinding equipment, argon two Welding machine, grinding machine; quality assurance-spectrum analyzer, three-dimensional these. This kind of all is more general and common, if it must be more advanced, it must also be a vacuum pump casting furnace or a vacuum heat treatment furnace or an x-ray.
The production volume of stainless steel precision casting steel castings is stable, and the quality, type and performance of stainless steel castings and the proportion of carbon steel and special steel continue to increase. The use of various refined processing techniques and technologies to develop and design new steel casting raw materials can enhance the strong ductility and unique properties of the raw materials.
