The feature:
Firebrick refers to the selection of refractory raw materials made of shaped refractory products, can withstand I580ºC above the high temperature products. The primary raw material is refractory clay (bauxite) mixed with clinker (calcined and destroyed clay), stirred, pressed by a strong machine, dry after more than 1000 degrees of high temperature calcination made.
Firebrick SK30, SK32, SK34, SK35 refers to clay bricks, AL2O3%(≥)30%, 35%, 38%, 45%, made of refractory clay and its clinker by destruction, mixing, molding, boring and acetylization and other processes. Refractory products classified as weakly acidic are enhanced with the addition of SiO2 content. It has certain corrosion resistance to acid, but poor resistance to alkaline corrosion.
SK36, SK37, SK38, SK40 firebricks refer to high aluminum bricks with alumina content of 55%, 65%, 70%, 82%, the selection of high bauxite as the primary raw material, with soft raw clay as a binder, after forming and burning at about 1500ºC. High aluminum bricks contain Al2O3 greater than 48%, its refractoriness, load softening point and reburning shorten indicators are higher than clay bricks, and the resistance to acute cooling and acute heat is worse than clay bricks. High aluminum bricks belong to neutral refractory materials, and the slag resistance is enhanced with the increase of Al2O3 content.
Company main products and profile:
Our total annual production capacity is about 100,000 tons of dense-shaped refractory product, and 100,000 tons of monolithic refractory product.
We have three tunnel kilns for silicon-aluminum dense bricks and one new plant for the monolithic refractory.
We're sure our custom-made products and professional services will bring you a stable quality supply and more profit.
