铸造生产是机械制造工业的重要基础,具有悠久的历史,在国民经济中占有相当重要的地位。随着当今科学技术的迅猛发展和市场竞争的日趋激烈,铸造企业为求生存必须不断地开发新产品,提高产品质量,降低铸件成本缩短产品研制的生产周期。 凝固过程是决定铸件质量的一个关键过程,各种铸造缺陷如缩孔、缩松、裂纹、变形和尺寸精度偏离等都与凝固过程
Casting production is an important foundation of the machinery manufacturing industry, has a long history and occupies a very important position in the national economy. With the rapid development of science and technology and the increasingly fierce competition in the market, foundry enterprises must constantly develop new products, improve product quality, reduce the cost of casting and shorten the production cycle of product development in order to survive. Solidification process is to determine the quality of castings a key process, a variety of casting defects such as shrinkage, shrinkage, cracks, deformation and dimensional accuracy deviations and the solidification process
