Present Situation and Development of Stainless Steel Casting

China's annual output of 36.5 million tons of castings, is the world's largest foundry, China is a large manufacturing equipment, the future of China will become a casting power, but China's casting industry is generally outdated equipment, technical strength is weak, high cost of pollution. 
Casting is one of the main methods to obtain the roughness of mechanical products. It is an important basic technology of the machinery industry and occupies an important position in the national economy. China's casting industry is the status of large output, with an annual output of about 36.5 million tons of castings, factory outlets, more than 20,000, the foundry industry employees in more than 1.2 million people. China's casting industry is a major feature of the reform and opening up since the rapid development of township enterprises, China's casting industry has become an important force. Township foundry points have exceeded the state-owned foundry, township foundry casting production accounts for about half of the country's total casting production. The following are the same as the "
At present, the development of casting technology in the industrialized countries of the world is summarized as follows: (1) Protecting the environment, reducing and eliminating pollution; (2) Improving the quality and reliability of castings and producing high quality near-end castings; (3) reducing production costs; Shorten lead time. There are gaps in quality, efficiency, energy and material consumption, working conditions and environmental protection compared with the developed countries, in addition to the factory and the number of employees in the casting industry. The reasons for these gaps are the small size of the foundry, poor economic strength, backward technology and equipment, low management level, the quality of employees is not high. In order to eliminate these gaps, in order to meet the needs of China's economic construction, but also to the casting industry's own existence and development of China's casting industry should improve the quality and economic benefits of casting as the center, for domestic and international markets; Improve the quality of enterprises; adjust the industrial structure, rational allocation of resources, to promote appropriate scale of operation; continue to apply advanced production technology and technical equipment transformation casting industry, to achieve clean production, to ensure sustainable development. 
Benefit is the basis for the development of enterprise development is based on efficiency, development is to achieve higher efficiency. China should have a highly efficient foundry industry. There is no benefit to the survival of enterprises is difficult, let alone development. In order to improve efficiency, we should proceed from the following aspects: ① reduce staff efficiency and energy saving. ② to achieve professional production. ③ the use of new technologies to achieve scientific management. 
Quality is the quality of life and efficiency of enterprises sometimes seem contradictory, but the two are unified. Poor quality of products after all, can not be based, not to mention the benefits, it is impossible to sustainable development. Improve product quality from the following aspects: ① reasonable purchase of raw and auxiliary materials, the correct formulation and strict implementation of the relevant technical procedures. ② the use of new technologies, new technology, new equipment, new materials. A. To strengthen the application of computer technology in casting production. B. In the sand casting using high hardness and high uniformity of the mold, the development and promotion of the corresponding technology and equipment. C. Development of near net shape and net casting process of new technology. D. The development of liquid metal processing and purification of new technology and new technology to optimize the material performance. E. Development of mechanization automation to ensure the stability of the casting quality, uniformity, improve working conditions. F. Strengthen the research and application of casting environmental protection equipment. ③ has a stable high-quality practitioners team. 
To achieve clean production Clean production is the basic requirement of sustainable development. Clean production means: to achieve the lowest possible resources (raw materials) and energy consumption; to achieve a pleasant production environment and the lowest or zero pollutant emissions; production of clean products (product energy consumption, less supplies, easy to regenerate And ergonomic requirements). Casting the clean production, mainly the application of new technologies, new technology, new materials, new equipment to achieve low consumption, low pollution or pollution-free and casting production of pleasant environment and so on.
