Abstract
An improved design of tundish which has chambers for the plasma heating of liquid steel has been developed and tested. The design of the tundish improves heat and mass transfer processes inside it. The new design elements of the tundish accelerate the entry of the metal into zone occupied by the high-temperature plasma in order to improve the conditions for its heating and making the metal’s temperature uniform throughout the volume of the tundish. Two tundishes of the new design were made and the plasma heating unit was factory-tested during the casting of steel on continuous caster No. 4 in the oxygen converter shop at the Magnitogorsk Metallurgical Combine.
