| Abstract: | In February 2010, the redueerg high speed sheft of the lance hoist was fractured when it was working ,that is part of NO.2 120t converter of Masteel＇s NO. 1 steelmaking and Roiling Group. The reasons for causing the accident was analyze and judged by Macro observation,Spectrum,Analysis of hardness and low times,Tensile and metallogTaphic analysis, Chemical composition test, Hardness testing and observation of the low times pickling,Tensile Properties and other methods. |
