target temperature at end of oxygen blowing(We can thus get the target temperature at end of oxygen blowing by using the endpoint control system of basic oxygen furnace (BOF). 通过使用氧气顶吹转炉终点控制系统,我们就可以得到停吹氧目标温度。)
turndown carbon accuracy(This light meter system has been successful in dynamically estimating carbon levels in low carbon heats (0.06% or less), and adjusting the oxygen blow for improving the turndown carbon accuracy. 光学仪表系统在动态测定低碳钢炉次(含碳量0.06%或以下)含碳量和调整吹氧提高停吹碳精度方面已获得成功。)
residence time distribution(The Residence Time Distribution (RTD) curve shows that at the outlet, a tracer pulse arrives a certain time after the start of the experiment; the signal rises quickly to a peak and then diminishes exponentially to zero. 停留时间分布曲线表明,在试验开始后的某一时刻示踪剂脉冲到达出口处时,脉冲信号首先快速达到峰值,然后按指数曲线衰减至零。)
steel residence time(【技】钢包注流进人中间包到流人结晶器的路程中,钢水在中间包内所经历的时间。单位通常用 min 表示。钢水在中间包内停留的时间越长,钢水中夹杂物上浮的时间就越充分,钢水就越干净。: ① The trial revealed that baffle boards increased the steel residence time and enhanced nonmetallic inclusion floatation. 试验显示:缓冲板提高了钢水停留时间、促进了非金属夹杂物上浮。 ②Baffles, weirs, and dams have long been in use to increase steel residence time and promote inclusion flotation to the tundish slag. 为了延长钢水停留时间、促进夹杂物上浮到中间包渣中,缓冲板、双挡墙已使用了好长时间。)
