1. Low creep series


The main applications of this series of refractory bricks in hot blast stoves are low creep high alumina bricks and low creep clay bricks.


(1) Low-creep clay bricks for hot blast stoves are made of high-quality clay clinker as the main raw material, which is formed by high-pressure molding and high-temperature sintering. The product has a high load softening temperature, good resistance to creep at medium temperature, and good impact resistance. The main refractory material at low and medium temperature.


(2) Low-creep high-alumina bricks are high-grade refractory materials made of super-grade alumina, fused corundum, and fused mullite as the main raw materials. The products have high refractoriness, high load softening temperature, and strong slag resistance. Features.


2. Silicon brick for hot blast stove


The silicon brick for hot blast stove is a silicon refractory product with crystalline quartz as the main crystal phase.It is mainly built in the high temperature part of the blast furnace hot blast stove.The hot blast stove silicon brick has stable volume, low creep, good thermal shock resistance and resistance. Hot spots such as good chemical attack.

3. Andalusite bricks for hot blast stoves Andalusite bricks for hot blast stoves are high-grade refractory bricks in silica-alumina refractory materials, which have very good thermal shock resistance and creep resistance, and are mainly used for hot air outlets and hot air Furnace door and other key parts.


4. High-alumina insulation brick for hot blast stove


The high-aluminum insulation bricks are manufactured by the foam method, which has the advantages of small volume density, high compressive strength, high load softening, small dimensional tolerances, and excellent thermal stability.It can effectively improve thermal efficiency, reduce energy consumption, and improve working conditions. To improve production efficiency and obtain considerable economic benefits, it is mainly used for hot blast stove insulation layer.


5. Aluminum heat insulation brick


According to the actual working environment of each part of the hot blast stove, selecting the appropriate refractory brick variety is a very effective way to extend the age of the hot blast stove
