摘要
分析煤矿 1 0 0 0mm带式输送机连接减速机和带式输送机联轴器中圆盘铸件产生缩孔、缩松的原因。采用平造立浇铸造工艺 ,消除了铸件中的缩孔、缩松等缺陷 。
Analyze the causes producing stressed holes and cracks on the disk cast between the velocity translator and the coupler in a one metre-long belt conveyor, by azimuthal manufacturing and vertical casting,erase the defects such as stressed holes and cracks on casts,so as to produce qualified disk cast steel pasts.
