(1)为防止不锈钢铸造时产生白口,除从工艺上采取措施外,必须使其壁厚不能过薄(有些资料指出,壁厚在15mm以上时,用金属型铸造铸件的转角处都必须采用圆角,对于铝合金、镁合金金属型铸造铸件的铸造圆角不应小于3-4m,对于铸铁、铸钢、铜合金金属型铸造件的铸造圆角可参见表1.1-32选取;
(1) generating white cast stainless steel to prevent, in addition to taking measures in the process, must make the wall thickness is not too thin (some sources indicate that casting round the corner wall thickness above 15mm, metal type casting must be in the corner, for Aluminum Alloy, magnesium alloy metal mold casting should not be less than 3-4m, for casting round cast iron, copper alloy mould casting can see table 1.1-32 selection;
(2)由于金属型和芯无让性,为便于取出铸件和抽出型,不锈钢铸造铸件的铸造斜度应比砂型铸造件的适当大一些,一般应大30%-50%,应该指出:铸造斜度大小除与合金种类、壁的高度有关外,还与铸件表面的位置有关,凡在铸件冷却收缩时与金属型表面有脱离倾向的铸件表面可设计较小的斜度,而在铸件收缩时趋向于压紧在金属型上的铸件表面应给予较大的斜度,各种合金的不锈钢铸造的铸造斜度;
(2) because of the metal type and the core that, for the convenience of the casting is taken out and the draw out type, slope casting casting should be suitably large than sand casting some cast stainless steel should be 30%-50%, it should be pointed out that in addition to the height of the slope of casting size and alloy type, wall, is also related to the casting surface the position, where the cooling and contraction and metal surface of casting surface can be designed from the tendency of small inclination, while casting shrinkage tend to be pressed on the surface of metal casting type should be given greater inclination, casting alloy casting stainless steel of various slope;
