关于提高电弧炉炼钢生产率和降低生产成本的新工艺技术,象泡沫渣、炉底偏心出钢、底喷吹和废钢高温预热等,都在不断地得到发展。同时,也因此导致现代电弧炉的设计装配有水冷炉壁、燃烧器、多功能喷枪以及利于采用高功率因素操作的串联电抗的超高功率变压器和采用可减少电耗损失、利于设备维修的“热臂”。因而AC炉(交流电弧炉)已成为具有很大竞争力的炼钢工具,目前最重要的是要进一步降低设备运行成本。
New process technologies that increase EAF steelmaking productivity and lower production costs continue to evolve, such as foaming slag, eccentric tapping at the bottom of the furnace, bottom blowing and preheating of scrap at high temperatures. At the same time, this has resulted in the design of modern electric arc furnaces equipped with water-cooled furnace walls, burners, multi-function spray guns and ultrahigh-power transformers for series reactance that operate with high power factor and ultra-high power transformers that reduce power loss and facilitate maintenance of equipment. Hot arm. " AC furnace (AC electric arc furnace) has become a very competitive steelmaking tool, the most important thing is to further reduce equipment operating costs.
