Abstract：
The characteristics of sand-lined metal mold for steel casting process were described from the aspects of high melting point,poor fluidity of molten steel and large shrink,etc.The film coated sand for sand-lined metal mold sand casting and its requirements for higher refractoriness and lower gas generation in the production of casting steel were introduced.Taking cast steel brake shoe holder as an example,the parting and core-taking methods were determined from the product structure,and the pouring process of one mould and six pieces was designed by sequential solidification method.The results show that the feasibility of the process is verified by computer simulation,and the product mass production is finally realized.
