采用偏心炉底垂直出钢技术的电炉，能否真正实现无渣出钢，与电炉的回倾速度有决定性的关系。抚钢从德国引进的５０ｔ超高功率电炉回倾速度慢，经常引起“下渣”、“跑钢”事故，每年造成经济损失百万余元。为提高电炉回倾速度，应用比例控制技术理论；对倾动液压系统进行全面分析计算，结合现场测试，提出对系统不做任何改造，不增加投资，只须用提高比例阀控制电流，加大比例阀开口度，将电炉回倾速度由原设计的１．５°／ｓ提高到３°／ｓ。实践证明，这是一种十分有效的方法，实现了无渣出钢。这对解决同类问题有一定的实用价值。
The use of vertical eccentricity bottom of the electric furnace technology, whether or not the real slag without tapping, and the furnace tilt rate decisive relationship. Fushun introduced from Germany, 50t ultra-high power electric furnace back to slow, often causing “slag”, “running steel” accident, resulting in annual economic loss of more than 1 million yuan. In order to improve the rate of electric furnace rollback, the theory of proportional control technology is applied. The hydraulic system of tilting is analyzed and calculated comprehensively. Combined with the field test, the system is proposed without any modification, no increase of investment, just increasing the proportional valve to control the current, Valve opening degree, the furnace back to the tilt rate from the original design of 1.5 ° / s increased to 3 ° / s. Practice has proved that this is a very effective method to achieve a slag free steel. This has certain practical value for solving similar problems.
