补充资料:212113浇冒口清理滚筒操作规程
生产率:5吨/时
1、遵守铸造设备通用操作规程。
2、工作前还必须遵守:
a、 检查滚筒内部锰钢板是否松动、如有松动,应及时紧固好;
b、 检查滚筒体入口处是否与滑道相碰,如果相碰应于脱开;
c、 先点动试车,然后空运转2-3分钟,检查传动系统(电动机、联轴节、减速器)和滚筒体的运动是否平稳,确认一切正常后,方可进行生产。
3、工作中还必须遵守:
a、 开车时,先开通风机,后开滚筒。停车时,先停滚筒,后停通风机;
b、 经常注意进料情况,过宽过长的料不得进入滚筒内,以免卡住滚筒,使得滚筒体撬起,甩到地坑内,造成设备事故;
c、 滚筒进料时,操作人员不要在地坑内停留;
d、 设备开动时,如果滚筒压在挡轮上,应通知维修人员调整,以免引起轴瓦发热,甚至烧坏轴瓦;
e、 不许浇冒口积压在滚筒出口处,以免妨障滚筒体动动。
4、工作后滚筒体内的浇冒口应完全卸尽。
