Quality standards for precision cast heat-resistant steel pans:
The quality inspection of heat-resistant steel trays for precision casting is an indispensable part in the production process of castings. Its purpose is to ensure that the quality of heat-resistant steel trays for precision casting is in line with the technology of delivery acceptance. The main quality inspection of heat-resistant steel trays for precision casting is mainly The basis is: casting drawings, quality standards for investment castings, or casting delivery acceptance contracts or agreements signed by supply and demand parties.
The use of precision cast heat-resistant steel trays will also find that the quality standards for investment castings are the same as the parts drawings. They are all important criteria for judging the quality of castings. From a worldwide perspective, there is no unified investment casting. International standards. Different countries have different standards, and only a few countries in the world have national standards for investment casting.
The status quo of precision cast heat-resistant steel pans:
The development of precision-cast heat-resistant steel feed plates also requires attention that since the reform and opening up, with the demand of the market, China's steel output and consumption have been continuously increasing. The quantity and variety of iron and steel materials produced in China can basically meet the domestic economic development and national defense needs.
After that, with regard to the development of precision-cast heat-resistant steel feed plates, it is necessary to pay attention to the fact that the production technology level of steel materials has also been significantly improved, and in-depth research and development, introduction and digestion, and secondary development have been carried out in continuous casting and rolling technologies. The work has reached or approached the international advanced level. Make the technical and economic indicators of steel production significantly improved. For example, the continuous casting and rolling technology and related processing equipment used on precision cast heat-resistant steel feed plates have been rapidly developed, resulting in a significant increase in the overall product yield of steel.
Finally, regarding the development status of the national heat-resistant steel feed trays for precision casting, it should be noted that the overall technical level and production level of iron and steel materials are still at an intermediate level and there is still a certain gap from the advanced level in the world, especially high value-added steel. The gap in product production is even greater. However, the restrictions on this aspect have obviously hampered the healthy and sustainable development of the downstream processing industry and even the entire industry chain, but these aspects can be improved.http://www.dmgcastings.com/
