The State Council is installed appoint can hang out his shingle supervise and direct accident of outflow of Na Gang molten iron

Xinhua net Beijing on October 12 report (reporter Zhu Liyi) national security superintended total bureau to reported Nanjing steely Inc. a few days ago " 10 · 5 " grave accident of molten iron outflow. The basis concerns a provision, the State Council is installed appoint meet what already had an accident to this investigate execute hang out one's shingle supervise and direct, investigate a result to will be announced to the society. On October 5 11 when 40 minutes or so, 5 blast furnace are in ironworks of Nanjing steely Inc. accident of outflow of water of cast iron of the hair in process of preparation stopping furnace, cause scald of 12 people death, 1 person. Steel share is collect ore is collected south choose, the integrated iron and steel works that coking plant, agglomeration, puddling, steel-making, steel rolling is an organic whole, the yield that has 7 million tons of 8 million tons of steel, rolled steel at present can. Ironworks of Na Gang share 5 blast furnace built go into operation 1998, stopped furnace 2006, overhaul hind opened furnace on June 19, 2007. Furnace look is 402 stere, produce per year can be 500 thousand tons, blast furnace sets 14 a place with a draught and a taphole, use structure of hearth of water-cooling of cup of pottery and porcelain of carbolic brick ＋ and PW not to have kind of the stuff on bell roof. On October 5, 2011 7 when 30 minutes, ironworks of Na Gang share 5 blast furnace ask to fall according to plan stopping furnace makings line 9 - undertake wind is operated 10 meters resting beforehand. Rest beforehand during wind, demolished a powerful person of roof big spread and gas sampling canal, installed roof to make water device, rift incomplete iron mouth is in furnace skin, got off incomplete iron mouth is in cooling wall, be opposite at the same time clean, barren is gas inside division of 5 heat group reach the establishment such as blast furnace oxygen boosting to undertake safe processing, cut off with common share cop. That day 11 when make 37 minutes, 5 blast furnace have answer wind. 11 when 40 minutes or so, when spot work staff is installing incomplete iron channel, a large number of molten iron open the position suddenly to pour out of beforehand from incomplete iron mouth, cause the 12 people death on incomplete iron platform, 1 person to get hurt. According to preliminary analysis, because carbolic brick suffers crucible interior,this accident is erode attenuate, detecting to its intensity and argumentation evaluates the rift below inadequate circumstance skin of furnace of place of incomplete iron mouth, answer wind operation makes force of furnace internal pressure elevatory, bring about wall of furnace of molten iron puncture to pour out of. Detailed account is investigating the accident further. The basis concerns a provision, the State Council is installed appoint meet what already had an accident to this investigate execute hang out one's shingle supervise and direct, investigate a result to will be announced to the society. To draw accident lesson, safety superintends total bureau to ask each district builds rigid overhaul system, be on guard serious especially big accident happens; Solid begin hidden trouble platoon to check processing, strengthen job of metallurgy company safe production; Begin safe production to standardize construction deep, foundation of safe production of tamp metallurgy company; Serious accident is investigated, increase responsibility to find out strength, lesson of cogent act reason promotes the work.
