Study on Numerical Simulation and Physical Simulation and Metallurgical Effect for Structural Optimization of Four-Strand Tundish in Bloom Casting
The flow field,fluid flow characteristics and heat transfer are studied by numerical simulation and physical simulation in four-strand tundish with different configuration in bloom continuous casting in steel works,and the best control devices are optimized.The results show that in order to meet the demands of flow field and temperature field,compared with the tundish with channel type induction heating equipment,the best control devices optimized in the tundish without it aredifferent.After the best flow control devices(bumper,V retaining wall with deflector hole devices and dam) without are used,peak time and average residence time of closer flow was prolonged,flow pattern of each nozzle was consistent and flow characteristics is improved efficiently;Extremum of temperature difference among each strand is reduced to 0.6K and temperature of the molten steel in the tundish was even ; Practical metallurgical effect was conspicuous, in productive process of 40Cr,continuous casting heats come up to 8 heats,extremum of temperature difference among strands is reduced to 4℃,content of TO of molten steel in the tundish is 10×10-6.
