STEEL CONTINUOUS MELTING METHOD

STEEL CONTINUOUS MELTING METHOD

In a process for continuous melting of steel from at least largely pre-reduced iron carriers, such as, for example, crude iron and/or scrap, wherein the melt is poured over into a ladle for subsequent metallurgical steps, the metallurgical slag is adjusted by the addition of fluxes to… 20-77.2% of F...
