SK32 Fireclay Refractory Brick for Hot Blast Stove High Temperature Resistance
The Descrition:
SK30, SK32, SK34, SK36, SK38, SK40 are more common shaped refractory grades in foreign countries, and the domestic refractory brick indicators are different. Among them, SK-30, SK-32, SK-34, SK-35 represent clay bricks, and SK-36, SK-37, SK-38, SK-40 refer to high aluminum bricks.
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.

Application:
Mainly used in the metallurgical industry, the manufacture of stereotyped refractories (bricks of various specifications) and non-stereotyped refractories, the amount of which is about 70% of all refractories, and the hard clay in the refractory clay is used to manufacture blast furnace refractories, iron furnaces, hot blast furnaces, steel barrel lining bricks, plug bricks, high aluminum clay is used to manufacture electric furnaces, blast furnace lining bricks and high aluminum refractory mud. However, hard clay and high aluminum refractory mud are usually burned at high temperatures (1400-1800ºC).
