【摘要】 用板状试样研究了形成光滑铸件表面的一般规律,提出了合理的涂料层结构及浇注、冷却条件,通过几种典型铸件试制,表明铸件表面粗糙度容易达到0.8～1.6μm,得到了满意的结果。更多还原

【Abstract】 General rules about forming smooth surface on a casting have been investigated with plate samples. Pouring and cooling conditions and reasonable structure of a coating are proposed. Some typical castings have been produced with satisfactory results. The roughness of the castings, with ease, reaches to a level of Ra更多还原
