flying tundish exchange(The two most common practices used to minimize the length of the transition bar are flying tundish exchanges and the insertion of separator plates. 将过渡坯长度减少到最短的两个最通常做法是快速更换中间包和插人钢种隔离板。)
flying tundish change(Unlike grade casting may be performed by one of two methods: either a "flying" tundish change, together with a grade separator plate, or a lowered tundish practice and grade separator plate may be used. 异钢种多炉连浇可以采用以下两种方法中的一种进行：采用飞包同时使用钢种隔离板的方法，或者采用降低中间包液位和使用钢种隔离板的方法。)
nozzle quick change(As mentioned previously, the ability to do nozzle quick changes (NQC) has been included in the tundish design in order to extend the number of heats in a sequence. 如前所述，为了提高连浇炉数，已将水口快速更换能力项目列人中间包设计。)
