在钢包冶金设备中用氧燃烧嘴代替电弧加热钢水是可行的。瑞典哈尔姆斯塔德钢公司在50吨钢包冶金设备上进行的大规模试验表明,在氧燃烧嘴单位功率为80千瓦/吨时,钢水温升为1℃/mln左右。在加热开始的12分内,热效率为35％,与电弧加热的热效率相当,预计总热效率达50％。氧燃烧嘴设备投资为电弧加热系统的20％,而操作费用低50％。
In ladle metallurgy equipment, it is feasible to use oxygen burner instead of electric arc to heat molten steel. Large-scale tests carried out by Halmstad Steel of Sweden on a 50-tonne ladle metallurgical plant show that the temperature of the molten steel rises to about 1 ° C / mln at an oxygen burner power of 80 kW / tonne. Within 12 minutes of start of heating, the thermal efficiency is 35%, which is equivalent to the thermal efficiency of arc heating and the total thermal efficiency is expected to reach 50%. Oxygen burner equipment invests 20% of the arc heating system, while operating costs are 50% lower.
