General Information
Modern hot stoves hot blast average temperature is up to 1,250 ℃- 1,300 ℃, so there are higher requirements on refractories quality, like checker chamber upper area, combustion chamber where are key areas for stoves campaign life. Therefore, some clients and experts have proposed the goal that campaign life of hot stoves should be twice as much as the life of blast furnace. Obviously, this is a challenge to refractories quality. It has become an important task for the refractory industry to select one kind of refractory with good thermal stability, high resistance to high temperature compression creep, high refractoriness under load and reasonable price to use in the hot stove with high blast temperature. The excellent performance silica brick has the following characteristics. The low creep, high refractories under load and low residual quartz contents, silicon bricks for hot stove of our company has been successfully applied to various types of hot stoves of major steel companies at home and abroad and the quality has been recognized by the clients.


Superior resistance to acids (including oxidizing)
Resistance to chlorine
Resistance to thermal shock and pressure changes
Low thermal and chemical expansion
