日本Chubu 钢板公司的Nagoya 工厂的200t 电弧炉,由于使用40MVA 变压器,生产率受到限制。在该电弧炉上采用三个双喷嘴煤油燃烧器后,得到以下效果:(1) 提高了能量输入强度;(2) 通过双喷嘴宽燃烧的应用加速了熔炼;(3) 增加燃烧器数量后达到有效预热作用;(4) 采用附加燃烧器后可以在炉门附近区域选择熔炼;(5) 易于进行废钢切割及放渣操作;(6) 生产率提高14%;(7) 当使用的燃烧器的效率大于80%电功率时效果最佳;(8) 有效利用补充燃烧能后,在难以提高输入电功率的大型电弧炉中,可以得到类似采用超高电功率的效果。
The 200t electric arc furnace at the Nagoya plant in Chubu Steel Co., Japan, is limited in productivity due to the use of 40MVA transformers. The use of three dual-nozzle kerosene combustors on the electric arc furnace results in the following effects: (1) increased energy input strength; (2) smelting accelerated by wide dual-nozzle combustion; (3) increased number of burners (4) the use of additional burners can be selected in the vicinity of the furnace door smelting; (5) easy to cut scrap and slag operation; (6) the productivity increased by 14%; (7) when the use of combustion The efficiency of the device is greater than 80% of the best when the electric power; (8) the effective use of supplementary combustion energy, it is difficult to increase the input electric power in large electric arc furnace, you can get the same effect of using ultra-high electric power.
