1998年6月12日和23日,宁夏恒力钢铁集团公司炼钢分厂相继发生了两起电炉爆炸事故。 6月12日零时55分,炉前工将废钢料加进熔池冶炼后,为急于脱碳出钢抢产量,操作人员向炉里投入了大块度的铁矿石,随后将铁锹头朝下架起吹氧枪一个劲的向炉内吹氧。这种习惯性的违章作业行为,使碳氧产生剧烈反应,热量和气体不能迅速扩散,导致钢液在瞬间产生大沸腾。炉前工杜××和岳××见炉况势头不妙,争相上前去按电钮,以提升炉盖泄压,避免爆喷。不慎两人相撞摔倒在地,这时爆喷已经发生,灼红炽热的钢水象固体重物喷溅到他们身上,工作服顿时着起火来。人挣扎着,肌肉燃烧点施放出一股刺鼻呛人的气味。杜、岳二人心里什么都明白,但什么都晚了。躯干、双臂剧疼。另一炉前工孙××在爆喷
June 12 and 23, 1998, Ningxia Hengli Iron and Steel Group Iron and Steel Plant Branch have occurred in two electric furnace explosion accident. At 0:55 on June 12, the front-end workers added waste steel to the melting pool for smelting. In order to rush for decarburization and steel production, operators poured large amounts of iron ore into the furnace and then put the shovel head Stand upwards and blow the oxygen lance out of the oven. This habitual violation of operating practices, the carbon-oxygen produced a violent reaction, heat and gas can not be rapidly spread, resulting in a large liquid steel boiling in an instant. Before the furnace Du × × and Yue × × furnace situation is not good, competing to press the button to enhance the lid pressure relief, to avoid explosive spray. Accidentally the two collided and fell to the ground, when the blasting had taken place, the red hot steel splashed onto them as heavy solids, and the working clothes suddenly caught fire. People struggled, muscle burning point cast a pungent choking smell. Du, Yue two hearts understand everything, but what are late. Torso, arms pain. Before the other furnace × × blast explosion spray
