1。每包铁水浇注完毕后,要将事先预制标牌(上面刻有该包次的序号)插入该包浇注的铸件的浇口杯中,用以防止不同包次的混淆。

1 after each ladle of molten iron is poured, it is necessary to insert the pre fabricated label (the number of the package which is engraved on it) into the pouring cup of the ladle casting to prevent the confusion of different packages。

2.每包铁水浇注后期制作抗拉试棒毛坯,作为一个检验批次,做机械性能、金相组织及硬度的检测。

2 each package of hot metal after the production of the tensile test rod blank, as a batch of inspection, mechanical properties, microstructure and hardness testing。

3.每包铁水球化之前要检测一次出炉温度,控制范围1400-1500℃。

3 each ladle hot metal to be detected before the release temperature, control range 1400-1500.

4.每包铁水球化完毕后,需检测一次铁水温度,控制范围在1360℃以上。

4 after each ladle molten iron is finished, it is necessary to detect the temperature of molten iron, the control range is above 1360 degrees celsius。

5.每日进行原铁水1—2个样品的五元素检测,用以控制铸件材质及炉料回收使用的稳定性。

5 the five elements of the original molten iron - 1 - to - 2 samples are tested daily to control the stability of the casting material and the recovery of the charge.

6。每包铁水浇注控制时间更长为10分钟(球化反应后)超过此时间则要报废处理。

6 the casting time of each ladle is 10 minutes (after the spheroidizing reaction), and it will be scrapped。

7.落沙时,需根据号牌分别堆放,不同包次不能混淆,等待试棒及金相的检测结果。

7 when the sand, according to the number of plates were stacked, different packages can not be confused, waiting for the test results and test results.

球墨铸铁井盖试棒机械性能结果合格后,及时通知车间清理。如果发现不合格包次,要依照标志牌号码逐个报废。

Ductile cast iron manhole cover after passing the test results of mechanical properties, promptly notify the workshop cleaning. If the unqualified packages are found, they shall be scrapped one by one according to the number of the signs.
