tap stream(① During tap, furnace slag is entrained into the tap stream from the vortex occurring over the tap hole. 出钢期间，炉渣卷人出钢口上方旋涡处流出的出钢钢流。② The amount of slag cany-over into the ladle depends on the ability to detect slag in the tap stream and of the mechanism of shutting off the tap stream. 下渣到钢包的渣量取决于出钢钢流炉渣的检测能力和关闭出钢钢流机构的能力。)
furnace slag entrainment into tap stream(In one practice avoiding furnace slag entrainment into the tap stream, the tapping process is terminated before the slag-metal interface reaches the tap hole, and steel is left in the furnace. 一种避免炉渣卷人出钢钢流的操作方法是在炉渣-钢水界面到达出钢口之前即终止出钢过程；这样，炼钢炉内会存留一定量的钢水。)
video image of tap stream(The major benefits of the infra-red slag detection system are providing a real time video image of the tap stream and giving an audio alarm with low maintenance, high reliability and use with easy. 红外测渣系统的主要优点是能提供出钢钢流的实时视频图像、发出音频警报，且维修量低、可靠度高、使用方便。)
slag entrainment into the tap stream(In the other practice avoiding furnace slag entrainment into the tap stream, the tapping process is terminated when slag is found in the tap stream. 另一种避免炉渣卷人出钢钢流的实用方法是：当出钢钢流中发现有炉渣时即终止出钢过程。)
