 電爐熔煉中易發生事故的應急處理

1、停電事故處理——冷卻水的應急處理
1. Emergency treatment of cooling water
(1)電爐控制室的配電總柜中雙電源開關應保持在自切換檔位,當主電源停電時,安保電源會自動切入,然后馬上再次啟動爐體水泵;
(1) The double power switch in the main power distribution cabinet of the electric furnace control room should be kept in the self switching position. When the main power supply is cut off, the security power supply will cut in automatically, and then start the furnace water pump again immediately;
(2)當主電源與安保電源同時停電,必須馬上通知值班電工,并且準備啟動應急發電機,保證爐體的小水泵有電后運行爐體冷卻水。因而柴油發電機必須保證具備一定儲量的柴油,而且與設備共同每月運行一次;
(2) When the main power supply and security power supply are cut off at the same time, the electrician on duty must be informed immediately, and the emergency generator must be ready to start, so as to ensure that the small water pump of the furnace body can run the cooling water of the furnace body after it is powered on. Therefore, the diesel generator must have a certain reserve of diesel oil, and run together with the equipment once a month;
(3)當柴油發電機也無法啟動,馬上對爐體切入自來水;(具體的進出水布置、操作方案由設備部門落實并報安全部門備案)
(3) When the diesel generator fails to start, tap water shall be cut into the furnace immediately; (the specific water inlet and outlet layout and operation scheme shall be implemented by the equipment department and reported to the safety department for record)


(4)由于停電,線圈的供水停止,從鐵液傳導出來的熱量很大。如果長期不通水,線圈中的水就可能變成蒸汽,破壞線圈冷卻,與線圈相接的膠管和線圈的絕緣都被燒壞。
(4) Due to the power failure, the water supply of the coil stops, and the heat transmitted from the molten iron is very large. If there is no water supply for a long time, the water in the coil may turn into steam, damaging the cooling of the coil, and the rubber hose connected with the coil and the insulation of the coil will be burnt out.
2、停電事故處理——爐內鐵液的應急處理
2. Treatment of power failure -- emergency treatment of molten iron in furnace
(1)冷爐料開始起熔期間發生停電,爐料還沒有完全熔化不必傾爐,保持原狀,僅繼續通水,等待下次通電時再起熔;
(1) When the cold burden starts to melt, there is a power failure, and the burden is not completely melted, so it is not necessary to tilt the furnace, keep the original state, only continue to supply water, and wait for the next power to start melting;
(2)由于中頻電源故障,鐵液已經熔化,但鐵液量不多而又無法進行澆注(溫度未到、成分不合格等),可以考慮把爐子傾轉一定角度后自然凝固。若量多,則考慮傾倒掉鐵液;
(2) Due to the failure of medium frequency power supply, the molten iron has been melted, but the amount of molten iron is not enough and the pouring can not be carried out (the temperature is not reached, the composition is not qualified, etc.), so it can be considered to tilt the furnace to a certain angle and then solidify naturally. If the amount is large, the liquid iron should be poured out;
(3)由于突然停電,鐵液已經熔化,設法在鐵液凝固之前在鐵液中插入管子,便于再次熔化時排除氣體,防止氣體膨脹而引起爆炸事故;
(3) Because of the sudden power failure, the molten iron has melted. Try to insert a pipe into the molten iron before it solidifies, so as to eliminate the gas when it melts again and prevent the explosion accident caused by gas expansion;
(4)對已凝固的爐料第二次通電熔化時,最好使爐子向前傾斜點角度,便于底下已熔化的鐵液在傾斜低處先流出一部分,防止爆炸。
(4) When the solidified charge is electrified and melted for the second time, it is better to make the furnace tilt forward, so that the molten iron can flow out at the lower part of the tilt to prevent explosion.
