杭钢2号高炉是1997年12月28日10∶25送风点火开炉的第四代新炉,名义有效容积为350m~3,实际计算容积Vn为366.16m~3,是我厂最大的一座高炉,自投产三个多月后,于3月18日发生了这起渣口爆炸事故。 1 事故经过事故经过是当天8∶00出第一炉铁前放北渣时,于7∶55发现北渣口带铁烧漏,堵渣口后关小水量,准备出完第一炉铁后更换。但因第一炉铁没有出好,堵铁口较早;渣口清理工作尚未结束,当时未料到其严重后果;炉内作业也未采取减风,控制料速等预防措施。直到9∶40才降压慢风作业,并准备推迟到第二炉铁(10∶00)后更换。值班工长8∶40与铁
Hangzhou Iron and Steel No. 2 blast furnace is December 12, 1997 at 10:25 on the 28th blast furnace blast furnace fourth generation, the nominal effective volume of 350m ~ 3, the actual calculation of the volume Vn is 366.16m ~ 3, is the largest factory A blast furnace, since put into production more than three months later, occurred on March 18 this slag mouth explosion. 1 Accident after the accident is the same day 8:00 out of the first slag before the North Slag, found at 7:55 North slag mouth with iron burning, plugging the mouth after a small amount of water, ready to finish after the first iron replace. However, because the first furnace did not work well, blocking the iron earlier; slag mouth cleaning work is not over, did not expect the serious consequences at that time; furnace operation did not take the wind, control material speed and other preventive measures. It was not until 9:40 that the pressure was slowed down and was to be delayed until the second furnace (10:00). Watchman 8:40 with iron
