Electric Arc Furnace

REFRACTORIES FOR ELECTRIC ARC FURNACE

WE SUPPLY VARIOUS REFRACTORIES FOR ELECTRIC ARC FURNACE

The furnace body of the electric arc furnace is in the shape of a teapot, which is a steel-making reaction vessel. The furnace body consists of a furnace body and a furnace cover (furnace top). The outer shell of the furnace body is made of steel plate, and the inside is the furnace lining. The furnace wall is built with magnesia brick (MgO) or chrome magnesia brick (Cr2O3, MgO). The bottom of the furnace is in the shape of a basin, and there is a layer of magnesia burning (playing) on the clay bricks and magnesia bricks. The acid furnace lining is built with quartz brick (SiO2) and quartz sand. In addition to the basic requirements of strength, high temperature resistance and heat insulation, the furnace lining refractory material is also required to withstand chemical erosion of slag, thermal shock of repeated rapid changes in furnace temperature, and collision of charge blocks and operating machinery.
