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。
The general law of forming the smooth casting surface was studied by the plate sample. The reasonable paint layer structure and pouring and cooling conditions were put forward. The trial production of several typical castings showed that the surface roughness of the castings could easily reach 0.8 ~ 1.6μm and was satisfied the result of.
