摘　　要：铸钢皮带轮 ,壁厚不匀 ,热节点多 ,补缩通道狭窄 ,很难用设置冒口的方法给予补缩。生产实践表明 :加大补缩压力 ,放置内冷铁调节各热节段的温度 ,使铸件实现同时凝固等工艺措施可成功地浇注出合格的铸件。Cast steel pulley with wall unevenness, many hot pitch points and narrow feeding channel is difficult to be fed by setting up a head. The practice of production indicates: the qualified cast can be successfully poured by technical measures such as increasing feeding pressure, placing an insert to adjust temperature of the hot junction segments and realizing simultaneous solidification of the casting.

关 键 词：精密铸造 补缩通道 同时凝固
