What are the properties and uses of different high alumina bricks?

2019-11-12

In the refractory industry, high alumina bricks can be divided into the following categories depending on their performance and use:

 
1. High alumina bricks and general high alumina bricks for rotary kiln.
 
Raw materials and processes: Generally, high-alumina bricks are made of high-quality bauxite clinker, supplemented with clay and additives.
 
Characteristics: The product has the advantages of high refractoriness, good resistance to acid and alkali corrosion, high temperature strength and good thermal shock stability.
 
Uses: Widely used in the thermal equipment of metallurgy, petroleum, chemical, building materials, machinery, processing and other industries.
 
2. High alumina brick for blast furnace
 
Raw materials and technology: The high alumina brick used in blast furnace is made of high quality bauxite clinker as the main raw material. It is formed by high pressure molding and high temperature sintering. The main mineral composition is mullite and corundum.
 
Features: The product has excellent high temperature mechanical properties and chemical resistance.
 
Uses: Used in various parts of blast furnace lining.
 
3. High alumina brick for steelmaking electric furnace top
 
Product features: High-aluminum brick for steelmaking electric furnace top is made of selected super-grade bauxite clinker as main raw material, which is formed by high-pressure molding and high-temperature sintering. The main mineral composition is corundum and mullite phase, with excellent high temperature mechanical properties and chemical corrosion resistance. In particular, it does not burn products, the dimensions are more precise, and the thermal shock stability is better.
4. High-aluminum bricks for steel drums
 
Product features: The high-aluminum brick used in Shenggang is made of selected bauxite as the main raw material. It is formed by high pressure molding and high temperature sintering. The main mineral composition is corundum and mullite phase, which has good high temperature mechanical properties and chemical resistance. Erosion performance.
 
5. Low creep series high alumina brick for hot blast stove
 
Raw materials and technology: Low-creep series high-alumina bricks for hot-blast stoves are made of corundum mullite and Yangquan high-quality bauxite clinker as high-pressure molding and high-temperature sintering.
 
Characteristics: The product has a high softening temperature, good high temperature creep resistance and excellent thermal shock resistance.
 
Uses: It is the material of choice for large and medium-sized hot blast stoves.
