摘要
采用VRH—CO2 水玻璃砂型工艺生产铸钢阀门 ,因地制宜选择铸造工艺参数 ;讨论了在生产中遇到的诸如铸型强度、表面稳定性、溃散性及阀体裂纹等技术问题 ,成功地生产了
In this paper the application of VRH-CO 2 silicate molding process in steel valve castings was studied. The processing parameters according to the test condition were optimized. In the mean time such as mould strength, surface stability, collapsibility and valve hot tearing, etc., were also discussed.
