最近,我车间3t/h冲天炉出了一起发渣事故,经分析,产生这次事故的主要原因是:1.在熔化过程中,上料小车发生故障,没有及时停风或者减小风量,底焦烧损严重。上料小车的故障排除后,又未加补焦,使底焦高度降低。2.层焦用量偏少,炉内风量过大。3.铁水氧化严重。发渣事故发生后,没有及时发现,未采取补救措施。 Recently, the 3t / h cupola in my workshop came out with a slag accident. After analysis, the main reasons for this accident are as follows: 1. During the melting process, there was a failure in feeding the car, there was no wind stopped in time or air volume was reduced, End coke burned serious. After feeding the car troubleshooting, they did not add coke, so that the bottom coke height is reduced. 2. Less layer coke consumption, the furnace air volume is too large. 3 serious oxidation of molten iron. Slag accident occurred, did not discover in time, did not take remedial measures.
