一、前言连铸中,由于使用了定量水口、塞棒或滑动水口,中间包与结晶器之间的注流控制已经得到实现。如果将各种系统作一比较,每个系统都有其优点和不足之处。例如定量水口最便宜,但也最不灵活。滑动水口最为昂贵,但却具有优于塞棒的某些灵活性。最近开发出来的旋转式水口则综合了塞棒和滑动水口的主要优点,并且克服了它们的不利因素。 I. Introduction Continuous casting, due to the use of a quantitative nozzle, stopper or sliding nozzle, tundish and mold injection control between the flow has been achieved. If you compare the various systems, each system has its advantages and disadvantages. For example, the cheapest outlet, but also the most inflexible. Sliding gates are the most expensive but have some flexibility over stopper sticks. The recently developed swivel nozzle combines the major advantages of plug and sliding nozzles and overcomes their disadvantages.
