How to learn foreign advanced foundry industry technology

Academic research in the field of casting in China is not backward, and many research results in the international advanced level, but less into realistic productivity. Domestic high level of casting production technology is limited to a few key enterprises, the industry overall technology level backward, casting quality is low, the material, the high energy consumption, economic benefit is poor, labor conditions and pollution. In concrete performance, appearance is still in manual or simple mould processing machinery; Casting the supply of raw and auxiliary materials production socialization, specialization, commercialization of gap is big, in such aspects as variety quality far cannot satisfy the needs of the development of new technology new technology; Casting alloy material production level, quality is low; Backward production management; Process design by personal experience more, less computer technology application; Poor casting technology and equipment, etc; Manual operation ratio is high, the production process workers technical quality is low; Only a few large automobile, internal combustion engine group foundry advanced modelling core-making process, most of the foundry enterprises still in shock pressure molding machine and manual, core-making binder such as tung oil, grease and clay sand to give priority to.
Overall casting in the developed countries advanced technology, products of good quality, high production efficiency, less environmental pollution, and commercialization of raw materials has formed series supplies, such as multinational service system has been established in Europe. Production is generally realize mechanization, automation, intelligent computer control, robots (operation). Cast iron smelting the use of large, efficient, dust removal, microcomputer measurement and control, external heat supply without lining water-cooled cupola continuous operation, widely used coke, cupola or with cupola furnace duplex melting, continuous desulphurization using nitrogen or wave packet in desulfurization of iron liquid sulfur content below 0.01%; Melting alloy steel refining multi-purpose AOD and VOD equipment, such as H, O, N in the steel liquid reaches several or dozens of 10-6 levels.
