Popis: | Continuous casting of steel with a high sulfur content is difficult due to clogging of the submerged nozzle. Physicochemical calculations and studies of a submerged nozzle inner cavity showed that clogging occurs due to formation of calcium sulfide and a low slag assimilation capacity. With serial melting of steel there is entry of slag into the tundish. Development of a slag forming mixture with whose application in the steel-pouring ladle there is formation of slag of this composition, which enters the tundish without worsening slag assimilation properties. Use of this development makes it possible to reduce submerged nozzle clogging and recycling of melts considerably due to stopping casting. |
