Casting Processes| Summary: | Stably compact nature of the outflow of an open metal jet from the tundish to the mould at the billet CCM is one of the conditions for achieving high rates of casting seriality, the quality of billets, minimization of metal losses and production costs. The publication presents the results of industrial studies of causes and factors that affect the hydrodynamics of an open jet, as well as recommendations for its stabilization. It is shown that casting speed is the most significant factor affecting the frequency of occurrence of «harp» jet cases. Therefore, in order to increase the productivity of the billet CCM, due to the maximum possible increase in the casting speed, it is also necessary to implement the proposed recommendations. |
