The converter plays the functions of decarburization, dephosphorization, desulfurization, alloying, heating, removal of inclusions, etc. In smelting, the converter does not need external heat and relies on the exothermic reaction of oxidation in the steel. In the converter, the furnace lining, steel outlet, breathable bricks, etc. are composed of refractory materials. Since its development in …
Medium frequency furnace use process, the thickness of the refractory material used for the furnace lining is only 70-110mm, the inner side of the contact with the high temperature metal liquid, the outer side of the water-cooled coils close to the refractory material inside and outside temperature difference is very large, in the use of …
