solidification front(The dissolved oxygen in steel combines with carbon to give carbon monoxide gas, which is released at the solidification front. 钢中的溶解氧与碳结合生成的一氧化碳气体在凝固前沿逸出。)
old grade of steel being cast(In the grade change operation, the tundish containing the old grade of steel being cast is first emptied to a certain depth before pouring the new grade from the ladle. 变钢种操作时，在由钢包浇人下一炉异钢种钢水前，首先将盛有上一炉正在浇注钢种钢水的中间包排空到一定深度。)
furnace operator(With the infra-red slag detection system all furnace operators are able to detect slag in steel stream at tap in a precise way, independent of their skill level or visibility conditions during the tap. 使用红外测渣系统时，所有的炉前工，不论其技术水平高低或出钢时环境能见度状况优劣，都能精确对出钢钢流裹渣进行测定。)
forehearth for continuous tapping of hot metal(① The Smelt Reduction Vessel is equipped with a forehearth for continuous tapping of hot metal. 熔融还原炉装备一个连续出铁前炉。②The forehearth for continuous tapping of hot metal can maintain an optimum bath level within the SRV. 连续出铁前炉能将熔融还原炉内的熔池液位保持在最佳水平。)
