在设计不锈钢铸造的基本结构单元及其参数选定时，通常应注意：
When designing the basic structural unit of stainless steel casting and selecting its parameters, attention should be paid to:
(1)为防止灰铸铁件产生白口，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;(2)由于金属型和芯无让性，为便于取出铸件和抽出型，金属型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；
(1) In order to prevent the gray iron castings from producing white holes, in addition to taking measures from the process, the wall thickness must not be too thin (some data point out that when the wall thickness is more than 15mm, the corner of the casting with metal mold casting must adopt rounded corners. For aluminum alloy and magnesium alloy metal mold casting, the casting rounded corners should not be less than 3-4m, for cast iron, cast steel, cast steel, cast iron, cast iron, cast iron, cast iron, cast iron, cast iron, cast iron, cast iron, cast iron, cast iron, cast iron, cast iron The casting fillet of copper alloy metal mold casting can be selected according to table 1.1-32（ 2) Because of the non yielding of metal mold and core, the casting inclination of metal mold casting should be larger than that of sand mold casting, generally 30% - 50%. It should be pointed out that the casting inclination is not only related to the type of alloy and the height of the wall, but also related to the position of the casting surface, The casting surface which tends to separate from the surface of the metal mold during the cooling shrinkage can be designed with a smaller slope, while the casting surface which tends to press on the surface of the metal mold during the casting shrinkage should be given a larger slope, and the casting slope of stainless steel casting with various alloys should be the same;
(3)由于金属型散热快，因此不锈钢铸造的最小壁厚应比砂型铸造铸件的要大一些，各种铸造合金、不同大小的铸造最小壁厚;(4)铸件内壁和内肋的厚度一般应取相连外壁厚度的0.6-0.7，否则由于内壁(肋)冷得慢，在铸件收缩时易在内外壁交接处产生裂纹。泥杆 保定空压机 保定古筝 塑料增韧剂 拱形护坡模具 保定空调维修 托辊设备  托辊生产线
(3) Because of the rapid heat dissipation of metal mold, the minimum wall thickness of stainless steel casting should be larger than that of sand mold casting（ 4) Generally, the thickness of the inner wall and the inner rib of the casting should be 0.6-0.7 of the thickness of the connecting outer wall. Otherwise, due to the slow cooling of the inner wall (rib), cracks are easy to occur at the junction of the inner wall and the outer wall when the casting shrinks.
