Alumina Silicate Lightweight Refractory Brick For Coke Oven and Hot blast stove
Definition:
Alumina Silicate Lightweight Refractory Brick For Coke Oven and Hot blast stove are mainly made from chamotte, being high pressure pressed and sintered in high temperature. Main minerals compositions are mullite phases. These products are widely used in all parts of furnace lining for middle and small capacity blast furnaces because of their excellent physical and chemical properties in high temperature. Alumina Silicate Lightweight Refractory Brick For Coke Oven and Hot blast stove also can be used in lining for other kinds of furnace.
Alumina Silicate Lightweight Refractory Brick For Coke Oven and Hot blast stove is a kind of alkali refractory bricks, the cement kiln block can also be synthetized as spinel, which is made into an amorphous refractory used for integral structures and internal lining. The production process of magnesite refractory bricks is basically in phase with the production process of common magnesia brick, However, each level of granule in the batching component is composed of a sintered synthetic spinel or an electrically fused spinel, or a mixture of the two.
Advantage:
1. Good thermal shock stability,
2. High temperature mechanical strength;
3. High softening temperature under load,
4. Good slag resistance and alkali salt resistance
Application:
Alumina Silicate Lightweight Refractory Brick For Coke Oven and Hot blast stove is mainly used for the partition of coking chamber and combustor of coke making furnace, regenerator chamber and cinder chamber of steelmaking open hearth furnace, soaking pit, refractory material of glass melting furnace and sintering furnace of ceramics and other kiln vault and other load-bearing parts.
ItAlumina Silicate Lightweight Refractory Brick For Coke Oven and Hot blast stove is also used for high temperature load bearing parts of hot blast furnace and acid open hearth furnace top.
