Abstract
Based on space-time multi-scale structure during material transformation process in melting and its effects
the 150 t electric arc furnace steelmaking process at Tianjin Pipe Co has been studied to realize the trans-scale energy integration of two unit- electric power supplying and oxygen supplying at working-level and to get math model for trans-scale energy integration at working-level. The results of 20 heats commercial test with quaternary charge structure show that better production effect is got by using the trans-scale energy integration's method
