Essay

The research is carried out on velositi field and structure of flows in tundish with the use of water model. Ratio of circulation and Pekle number for tundish of various design were established. Mathematical model of coagulation and removal nonmetallic inclusions in tundish is developed. The results of modelling are confirmed by industrial experiments. On the basis of research the secondary oxidation in tundish the dependence of decrease aluminium concentration in steel is established for the case of pouring by method "heat on heat" from heat number in series. Method of calculation the adjusting addition of aluminium in tundish at the beginning of heat is offered and tested in industrial conditions and realised in industry.
