Silica Brick for Hot Blast Stove
1: Silica brick is mainly used for hot-blast stove, tunnel kiln, Coke oven, glass kiln, Acidic furnace non-ferrous metal smelting and some other thermo technical equipment in good furnace building materials.
2: The advantages of CUNSE silica bricks for Hot Blast Stove
high purity, good thermal conductivity, high refractoriness under load and high tridymite content, low true density, low expansion, low creep and low residual quartz content, good dimension and appearance.

AREAS OF APPLICATION:
•Widely used in hot blast stoves.
•Used in high temperature sections of the checker chamber in hot blast stoves.
•Used as low-cost alternative to andalusite and mullite checker bricks in hot blast stoves.
•High refractoriness, average thermal shock resistance makes it suitable in consistent temperature environment.
