(II) normal inspection and pre prevention standard

1 The foreman of the cast iron machine checked the condition of the molten iron tank recorded by the can manufacturer every day from time to time, and checked the molten iron tank at random to visually check whether the tank mouth, slag raking mouth refractory, and the external brick lining are scattered, and make a record. Check the newly built iron water tank (see Appendix IV), and bake it if appropriate (see Appendix I for baking requirements). Count the utilization times of molten iron tank once a week. For hot metal tanks that have been used for 400 times and can also detect bolts, anchorages, anchor cables, single ring chains, double ring chains, 3-ring chains, conveyor belts, steel strands, etc. in mining equipment, we should pay more attention (focusing on whether the external brick lining is scattered). During the use process, we should check it irregularly every day. If it meets the scrapping standard (see article 4 of Appendix I), we should stop using it immediately

2. In the daytime, the shunter shall visually check whether the brick lining of the molten iron tank is scattered, whether the slag raking nozzle and the refractory of the tank nozzle are thinner and scattered, and make a record. The shunter on the night shift every day stops measuring the temperature of the hot metal tank skin (160 ℃ -260 ℃) with a temperature gun at the desulfurization station, and makes a temperature record

1. During the inspection, it was found that the refractory materials of the tank mouth and slag raking mouth were scattered, which was immediately handled by the tank laying staff. The repairable repair (the tank mouth was not burnt out, but the refractory materials were scattered) could not be handled by the organization offline (the tank mouth was burnt out)

2. If the temperature of a certain part is found to be high (exceeding 260 ℃), immediately tell the train monitor that the group leader will coordinate the converter crane operator to clean the iron in the tank, and then go offline and the can laying manufacturer will check the notice

3. Cast iron team leader and train team leader shall follow the requirements in the inspection standard. If abnormalities are found in the inspection, the cast iron team leader and the can laying manufacturer shall stop confirming the abnormal environment. If it is identified as a serious hidden danger, it must be handled immediately

4. If the mechanic finds that the nozzle, hoop, trunnion and trunnion retaining ring of molten iron tank are desoldered, he shall immediately tell the train monitor to organize the production line, and the mechanic shall be responsible for repair welding

5. The workshop director found that the above staff did not check as required during the inspection, and was assessed according to the regulations, and told them to rectify at the same time
