In the face of the global information technology, unprecedented high speed development, machinery manufacturing industry especially the modernization level of equipment manufacturing industry of high-speed increase, China foundry industry when a clear understanding of their historical task and the developed countries and the reality gap, bold use of the latest achievements of human civilization. Understand that the "only to realize high-tech industrialization in order to keep pace with the times" the truth, tactfully grasp the development trend of modern casting technology, rational use of advanced and applicable technologies, wise to implement the strategy of sustainable development, based on the reality and look far ahead from a high plane, to the revitalization and development of China's foundry industry fruitful to lay a solid foundation for Chinese modern industrial civilization. 1 developed country casting technology development situation in developed countries generally advanced casting technology, products of good quality, high production efficiency, less environmental pollution, raw and auxiliary materials, has formed a series of commodity supply, such as in Europe, has established multinational service system. The production of the universal realization of mechanization, automation, intelligent (computer control, robotic operation). The 2 China foundry technology development status of domestic foundry production of a high level of technology is limited to only a few backbone enterprises, industry overall technical level is backward, low quality, materials, high energy consumption, economic efficiency is poor, poor working conditions, pollution is serious. Academic research of China foundry technology is not backward, many research achievements have reached the international advanced level, but the productivity of translate into reality the less. The 3 China foundry technology trend of development of wear and corrosion resistance, heat-resistant special alloy new material; development of casting alloy steel (such as new varieties of nitrogen containing stainless steel material with high performance price ratio), improve the material properties, utilization rate, reduce the cost, shorten the production cycle. The development of high quality aluminum alloy materials, especially aluminum matrix composites. Ways of strengthening principle and aluminum alloy of aluminum alloy element. Study on the reduction of Fe, Si, Zn content in the alloy, ways to improve the method of strong toughness of the alloy and alloy heat treatment reinforcement. |
