The main method of stainless steel precision casting mirror treatment effect

Edit:Xiangyang Liqiang Machinery Co., Ltd.UpDate:2019-10-09

In the whole process of making stainless steel precision casting, the hydrochloric acid air oxide film is a key element that harms the air oxide film of aluminum alloy die castings. The porosity, purity, thickness and thickness of stainless steel precision castings Its sealing quality, etc. all immediately interfere with the actual effect of the mirror glass of the casting

If there are more residues in the air oxide film in the precision casting of stainless steel parts, its purity will be low and the clarity will be reduced. The residue in the air oxide film is mainly derived from the aluminum alloy die casting itself, and some of it comes from the air oxidation bath. Therefore, moderately reducing the water content of the aluminum alloy element in the casting can reduce the residual water content as much as possible.

The necessary machinery and equipment for the basic steps of precision casting of stainless steel parts are: high-precision casting wax injection-wax injection machine, ice water machine, central air conditioning; slurry-slurry bucket, floating sand machine, central air conditioning, dewaxing furnace, dehumidifier, In addition to liquid buckets, static buckets, and slurry dipping, mechanical arms and automatic centralized wax supply system software can be used;

Gold melting-sintering furnace, spiral furnace, shell vibration machine; post-processing technology-cutting machine, grinding machine, sandblasting machine, sand cleaning machine, heat treatment furnace, 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 must be more advanced, also must vacuum pump casting furnace or vacuum heat treatment furnace or x-ray these.

Stainless steel precision castingThe production volume of steel castings is relatively stable, and the quality, type and characteristics 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 characteristics of the raw materials.
