EAF roof with high alumina bricks, refractory bricks, recommend products industry

 Furnace lining refractories should have requirements? (1) high refractoriness; (2) strong resistance to slag erosion properties; (3) strong resistance to mechanical impact scrap; (4) good resistance to thermal shock performance (5) Load softening temperature; (6) high temperature slight swell. Furnace refractory lining commonly have? (1) Class of sintered magnesia bricks, magnesium carbon, tapping hole brick base, taphole sleeve brick hearth conductive MgO-C. (2) there is brine unshaped refractory magnesia, magnesia dry stripping, magnesia gunning, taphole filler, the conductive fed with cold, heat feeding. Alumina bricks Product performance: a strong high temperature volume stability, excellent thermal shock resistance, abrasion resistance, chemical resistance and other characteristics. Main purpose: Cement kiln transition zone, preheater and other requirements on thermal shock thermal equipment.

E.g., T-3 brick, almost the furnace can be used. 2, can cooperate with each other. Such as T-19, T-20 and T-52 brick arch angle can be used in conjunction with masonry arch and door. T-38, T-39 and T-61 brick arch angle can also be used in conjunction with masonry arch into the door. Not only with the use of common brick, and according to the radius of the situation span accurately calculates the number of silicon numbers and brick used.
