Abstract

According to structure and operation parameters of a 32 t tundish for 150 mm X 150 mm 6-strand concasting billet at steelmaking workshop

Shuicheng Steel

the effect of gas curtain technology on characteristics of liquid flow in tundish and removal rate of inclusion particles in steel has been studied by using mathematical simulation method

and the commercial test for casting HPB235 and 65 C steel is carried out. Results show that the gas curtain weir is available to improve flow situation of liquid

balance residence time at each outlet

effectively prolong the residence time of liquid in tundish

decrease dead zone volume and increase removal rate of inclusion particles. This technology is suitable to meet the requirement for cleanliness steel steelmaking with tundish for multi-strand casting.
