摘要
介绍了梅山钢铁公司2号LF的主体设备及工艺参数，以及在生产使用中对温度、脱硫、脱氧、增氮控制的效果。经过一段时间的生产，设备运行正常，平均升温速度为3～4℃／min，温度控制精度为±5℃；能稳定批量生产成品叫（S）≤20×10^-6的超低硫钢，最低出站叫（S）可达4×10^-6左右；出站w（0）≤35×10；氮质量分数增量Aw（N）≤8×10^-6；各项工艺技术指标均达到设计要求。
The present paper introduces briefly the main equipments and technological parameters of No. 2 LF refining furnace at Meishan Iron and Steel Company and describes its production effects in controlling temperature, desulfurization, deoxidation and nitrogen pick-up. Through a period of production the equipments are running normally, the average rate of temperature rise reaches 3-4 ℃/rain and the temperature control accuracy attains ±5℃ and the lowest w（S） is about 4 ×10^-6 and large quantity of ultralow sulfur steel with w（S）≤20 ×10-^6 could be produced steadily. The targets of w（O）≤35× 10^-6 and the increased w（N）≤8 × 10^-6 are realized and each technological index arrives at the designed specification.
