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, i. e. average tapping liquid amount 141. 2 t; electric power consumption for melting 314. 3 kWh/t; oxygen consumption 41. 0 m3/t; oxygen efficiency 87. 7% ; metal yield 88. 5% and tap-to-tap time 49. 5 min.
