Problem Counter Measures of the Casting Technology

Casting is a main metal forming method which is the basis of thermal processing. Advanced casting technology in the developed countries in general have good product quality, high production efficiency and low environmental pollution. Raw and auxiliary materials have formed a series of castings exports despite of the growth, but exports account for only 97% of our total production of the world's casting and less than 8% of the liquidity is in the market, the overall growth rate is slow and performance is poor , low price is caused by technological backwardness. Outdated equipment, high energy, raw material consumption and serious environmental pollution are problems. Workers in harsh operating environment and other issues, has become the consensus of the industry.

Its content in terms of mechanical vibration noise, and some still in high temperatures operations such as melting, casting. Some will produce a pungent odor, dust operating environment is even worse. Using high-tech green casting need to focus on resolving these key issues. Basic research and applied research to strengthen the foundry industry and many metal materials are common and critical, and therefore it should focus on technology research , improvement of materials technology and advanced computer simulation technology, while strengthening adopted to stabilize the product quality .

In fact, the domestic over-emphasis on the development of new materials and the neglect of the universal critical materials, process design and quality aspects of research have produced many equipments with many issues, such as the sand washer equipment in the Three Gorges turbine runner and stone production line equipment components. Increase the casting organization and restructuring of enterprises, specialized products need to be made. Gathering localization growth of leading enterprises, SMEs around the industry chain gathers basic supporting special process equipment, testing equipment,...
