金属型复砂造型是目前铸造战线上的一项新工艺,并在不断发展应用。这项新工艺对铸钢、铸铁能获得精度较高,光洁度较好的铸件。特别对铸造球墨铸铁更显出它的优越性,由于铸型刚度高、冷却速度快,可以不用胃口浇注出致密完整的铸件,并在同样的铁水条件下,其机械性能指标比砂型铸 Metal-type sand molding is the casting front of a new technology, and continue to develop and apply. The new technology on cast steel, cast iron can get higher precision, better finish castings. Especially for casting ductile iron shows its superiority, due to the high stiffness of the mold, cooling speed, you can not cast an appetite dense and complete castings, and in the same hot metal conditions, the mechanical properties than the sand casting
