美国伯利恒钢厂碱性吹氧转炉车间从一九七○年九月十五日开始采用一种监控转炉炼钢终点含碳量和终点温度的传感枪装置。用了该装置后,无需重吹或冷却而准确出钢的次数百分比由31%上升到62%;加热时间平均缩
Bethlehem Steel Bauxite Oxygen Oven Plant in the United States has adopted a sensing gun device for monitoring the carbon content and the end temperature of the converter steelmaking end since September 15, 1970. With this device, the percentage of accurate tapping without re-blowing or cooling rose from 31% to 62%; the average heating time was reduced
