热芯盒射芯机制芯工

Core ejection mechanism of hot core box

1、工作前穿戴好劳保用品。确认制芯机内无人工作且周边人员均处于安全位置；检查电器、天然气加热系统是否正常;各种连接螺丝是否松动；砂筒、射头、风管、气管有无障碍，待各部位检查正常后，方能开机工作。

1, wear good labor insurance articles before work. Verify that the core machine is not working and the surrounding personnel are in a safe position; check the electrical and natural gas heating system are normal; all kinds of connecting screws are loose; the sand barrel, ejection head, wind pipe, and trachea have no obstacle, and the work will be opened after the inspection of each part is normal.

2、天然气加热系统应按天然气使用规定进行：首先打开通风装置，然后用长棒点火放在气喷嘴上，再放开气阀门由小到大，均匀点火。严禁先放气后点火，以防爆炸或中毒。

2, the natural gas heating system should be carried out according to the use of natural gas: first open the ventilation device, and then use the long rod ignition on the gas nozzle, and then release the gas valve from small to large, uniform ignition. It is forbidden to ignite after deflation to prevent explosion or poisoning.

3、燃气压力低于规定值时，操作者应停止加热操作，经维修人员调整压力后，方可工作。

3. When the gas pressure is lower than the prescribed value, the operator should stop the heating operation and adjust the pressure after the maintenance personnel can work.

4、必须保证射砂筒有足够的液压钢坝  芯砂（一般不少于2／3射砂筒容积）方可射砂，严禁无砂空射。

4, we must ensure that there is enough core sand (usually not less than 2 / 3 shot sand tank volume) to shoot sand, and no sand and air shooting is strictly prohibited.

5、操作时，严禁手触芯盒，从芯盒中拿取砂芯及对射砂板孔通砂孔时必须戴好手套，以防烫伤手。从芯盒中取出的砂芯要堆放整齐，防止倒塌。

5. During operation, it is strictly prohibited to touch the core box by hand, take the sand core from the core box and wear gloves when the sand passes through the hole, so as not to scald the hands. Sand cores removed from the core box should be stacked up to prevent collapse.
