AOD furnace is mainly used to smelt stainless steel, which has the advantages of simple device, manipulating conveniently, low construction fee and remarkable economic benefits.

　　Within that process of smelting, slag changes from acid to basic, from oxidation atmosphere to reducing atmosphere, and be operated batchwise when smelting in order that the temperature of furnace linings are relatively high and fluctuate tempestuously.

　　Consequently, the working life of the furnace linings are very short. As the the industrial solution leader, Hitech Material provides a comprehensive solution for AOD furnace.

　　Magnesia chrome bricks are generally used for AOD furnace linings. Nevertheless, with complicatedproduction process, high energy consumption and environment pollution, magnesia chrome bricks are gradually superseded by magnesia dolomite bricks.

　　Sintered magnesia dolomite bricks can be used for furnace wall, slag line, trunnion and tuyere, etc.

　　Resin bonded magnesia dolomite bricks are generally used for slag line zone, bottom, etc;

　　Besides, magnesia-dolomite series of gunning mix, joint filler and mortar are also widely used for AOD furnace.
