Because the refractory materials used in the two mechanisms are not universal and correspond to different smelting steel grades, it is necessary to prepare the two mechanisms' tundishes in advance in actual production to cope with the different production steel grades, resulting in a large number of spare tundishes. When the tundishes of a single mechanism are produced continuously, the turnover of the tundishes is difficult, and sometimes the steel grade plan has to be changed, affecting the production plan and order delivery. Therefore, in view of the above problems, a universal mechanism suitable for the quick-change water inlet and emergency gate system is designed to better meet the actual use needs.
