摘要
采用喷吹技术连续向熔池喷吹焦粒和提高供氧强度，在150t的电弧炉熔炼过程形成连续稳定、高度500～800mm的泡沫渣，遮蔽了电弧，降低了噪音。经过500炉的实验，其结果节电＞30kWh／t，供电时间缩短3～5．5min。
The technology for continuously injecting coke powder and the measure for increasing oxygenflow rate have been adopted to get steady foamed slag depth of 500-800 mm, by which the electric arc wasshaded and the noise lowered. With 500 heats experience the results shown that the average electric powerconsumption decreased more than 30 kWh/t and the power on time decreased 3-5. 5 min.
