Analysis of Basic Oxygen Furnace’s Temperature by the Flame’s Emission Spectrum Lingfei Xu1,a, Wusen Li1,b, Shixue, Xu1,c, Jia Li1,d, Yongqing Wang1,e 1Group 432 Department of Optical Engineering Nanjing University of Science and Technology, Nanjing, Xiao Ling Wei 200 China ajsj900@hotmail.com，bliwusen@mail.njust.edu.cn, cete_corner@yahoo.com.cn, dlijiafeifei@sina.com , esyusqing@163.com Keywords: emission spectrum, FES, spectrometer, BOF Abstract: The flame of basic oxygen furnace is the most important evident in the steel making process.
In the combustion of material with high concentration of carbon, there exists the emission peak in its flame spectrum at 527nm to 616nm which is the Na.The emission line could be treated as the atomic transition between two energy levels.

In order to verify the simulation results are consistent with the calculated values,the force of five points of crank were selected analyse.As shown in Table 2, Table 2 Comparison Table Selected Point Crank Angle(°) Center Piston Angle(°) Simulation Result(N) 1 133.6 37.12 1.268 2 170 47.24 1.4 3 193 53.36 3.758 4 206.5 57.36 3.998 5 287 79.72 13.46 The gravity accelerate and material property of components were sited in simulation enveriment. which caused that Crank have inertia. a certain angle of center piston and pendulum bar should be maintained.
