Alloy steel castings to choose suitable investment pattern materials for investment, with repeated on the casting refractory coating and sand and refractory working procedure, sclerosis type shell and dry, then the internal casting melt away, get the cavity, roasting shell in order to obtain enough strength, and burn off the remnants of casting materials, metal materials, casting need cooling and solidification shell after deoxidization, can achieve the high precision finished products.
Technical level of alloy steel castings
1. Develop simulation technology to improve the accuracy of prediction, strengthen process control and improve yield.
2. Combination of production, education and research.In addition to the enhancement of innovation consciousness and the improvement of research and development ability, enterprises' independent innovation also needs to attach importance to and strengthen the combination of "production, study and research" with precision casting enterprises as the main body.
3. Attach importance to material research and development.Materials are the foundation of industry and there is still much work to be done.In the field of aerospace, research on some new materials, such as alloy materials, especially high temperature alloys.
4. Pay attention to the improvement of equipment technology.http://www.wuxiorient.com/
