摘要/Abstract

摘要： 用CFX5.7.1 软件对电弧炉炼钢用集束射流氧枪和普通氧枪的射流特征进行了数值模拟和冷态试验。结果表明，集束射流氧枪比普通超音速氧枪射流长，射流集中、衰减慢。在鄂钢70 t Consteel电弧炉上应用表明，使用集束氧枪后平均电耗由338 kWh/t降低到219 kWh/t,电极消耗未变，为1.86 kg/t,氧耗由 51.6 m³/t提高到60.3 m³/t。

Abstract: Numerical simulation and cold status test of jet flow of coherent jet oxygen lance and common oxygen lance for arc furnace steel making have been carried out by CFX5.7.1 Software. Results showed that the jet flow length,concentration and anti-attenuation of coherent jet oxygen lance were better than that of common oxygen lance. The application to a 70 t Consteel arc furnace at Ezhou Steel indicated that after using coherent jet oxygen lance,the electric power consumption decreased to about 219 kWh/t from 338 kWh/t,the electrode consumption was no-change (1.86 kg/t)and the oxygen consumption increased to 60.3 m³/t from original 51.6 m³/t.
