电弧炉炼钢过程受炉料、加热方式、炉形、供氧条件等的限制,其搅拌程度与转炉相比相去甚远。因而在金属熔体中存在着较大的温度梯度和浓度不均匀性。因此,强化搅拌是提高电弧炉生产率、降低消耗的重要手段。进入80年代,顶底复吹转炉的成功,使电炉工作者受到启发,很快将底吹惰性气体的技术移植到电弧炉上来,并获得成功。 Electric arc furnace steelmaking process by the charge, heating mode, furnace shape, oxygen conditions and other restrictions, the degree of mixing with a far cry from the converter. Thus, there is a large temperature gradient and concentration unevenness in the metal melt. Therefore, strengthening the mixing is to improve the productivity of electric arc furnace, an important means to reduce consumption. Into the 80’s, the success of the top and bottom double blown converter, electric furnace workers inspired, and soon will be blowing inert gas technology to the electric arc furnace, and success.
