Abstract: The main types of tundish nozzle clogging in continuous casting were introduced, mechanism of Al₂O₃ adhesion and research status of preventing measures at home and abroad were analyzed and summarized, and research direction of preventing measures was discussed.In view of the problem of tundish nozzle clogging, research of preventing measures were carried out, and the certain effect had been obtained, but problem of nozzle clogging still had not been solved thoroughly.Predecessors' research showed that it had obviously improved the effect through improving nozzle material.Presently, single material could not meet the demands of the development of continuous casting, material of basic spinel and low infiltration would be important direction. Inclusion transmiting to nozzle inner wall was the control link of nozzle clogging, due to the high temperature liquid steel invisible, numerical simulation method was usually used to study.Method based on coupling with EDEM-FLUENT could describe the flow behavior of liquid steel and movement of inclusion particles, so this simulation method would be the direction of numerical simulation research for mechanism of high melting particle adhesion.
