对于壁厚基本均匀的炉围壳体铸钢件,按照均衡凝固理论的铸钢件动态顺序凝固原则进行铸造工艺设计;利用凝固过程自补缩,可使铸件表面质量好,无缩孔、缩松等铸造缺陷,工艺出品率大大提高。 Casting process design for the furnace shell with a uniform wall thickness is based on the principle of dynamic solidification of steel castings based on the theory of equilibrium solidification. Using self-shrinkage during solidification, the surface of the castings is of good quality with no shrinkage and shrinkage Casting defects such as pine, craft production rate greatly improved.
