电炉炼钢时，如何确保安全生产？

[ 2011-7-27 15:54:00 | By: 杨远锋 ]

电炉炼钢法是主要炼钢方法之一。它是靠石墨电极和金属料之间所产生的强烈电弧供热。电弧处能产生3000℃～6000℃的高温，一方面能冶炼难溶金属，另一方面也给炼钢工人操作时带来热辐射的危害。在冶炼过程中电炉还产生大量烟尘，直接危害工人的健康。在操作过程中忽视安全操作，易造成伤害事故，为此应该在以下几个方面加以注意，确保安全生产：
（1）电炉装料装料时注意不要加进有害元素，如铜、锌、锡、铅等，这些元素会降低钢的质量。炉料中也不得混有爆炸物，以免造成爆炸事故。加料时人应尽量站在侧面，不能站在炉门及出钢糟的正前方，以免钢渣喷射伤人。炉料全熔后，不得再加入湿料，以避免爆炸。
（2）冶炼操作在冶炼过程中，如操作不当也会造成事故。配电工要了解冶炼过程对配电的要求，加强对变压器的维护和冷却，同时也要注意冶炼过程中氧化期炉内大沸腾时，应及时停电并抬高电极；出钢时必须切断电源并抬起电极。换电极时要先切断电源，操作人员要站稳，拉接时不能用力过猛，还要防止手套及工作服被挂在设备上。吹氧操作时，吹氧压力不能太大，手握部分要离接头远些，不能用吹氧管捅料。停上吹氧时，应先关闭氧气，后取出吹氧管。操作人员站在炉前操作时，应尽量站在门两侧。当炉内发生剧烈沸腾时，应立即切断电源，抬起电极，停止加料和吹氧操作并采取相应措施。准备出钢时，集体操作应密切配合，协调一致,操作人员背后不要站人，炉前应避免加入氧化剂，倾倒钢水时不要过快，以免飞溅伤人或损坏设备。
