重型灰铸铁工作台的铸造工艺

随着近些年来机床行业的快速发展,超重型高精度立式机床的生产成为我公司的主要产品结构。工作台作为立式车床的主要零件,对导轨及工作台面的质量要求严格,不得有缩松、缩孔、密度差等铸造缺陷,针对这种情况,在生产中采取了高温出炉,低温浇注,多次补浇,同时结合随流孕育和瞬时孕育,以起到加强孕育效果,减少孕育衰退,从而获得了组织致密,质量符合要求的铸件。

Casting Process of Heavy Gray Iron Bench

With the rapid development of machine tool industry in recent years,the production of super-heavy and high-precision vertical machine becomes the main product in my company.As the main parts,the rail and the top surface of the bench is required to have hot shrinkage and density defects.By applying high temperature melting,low temperature pouring and after teeming times combined with stream inoculation and instant inoculation,the high quality castings with compact structure are produced.
