1. Main features: Usually when hot blast temperature is higher than 1200℃, the refractory products for hot blast furnace is very limited. Silica brick has characters of low creep, high strength and thermal shock resistance and etc. under high temperature.
2. Application: Silica brick for hot blast furnace is mainly used in roof , wall and above parts of regeneration zone of the hot blast furnace.
