Refractories with a refractoriness of more than 1700 degrees are a kind of high-temperature fire-resistant material, usually made of inorganic non-metallic materials. These materials can withstand extremely high temperatures and pressures, and have good chemical stability and mechanical strength, so they are widely used in high-temperature equipment and furnaces in industrial production. The following are some common refractories with a refractoriness above 1700 degrees.

1, Alumina brick: Alumina brick is a high temperature ceramic material, with excellent wear resistance, corrosion resistance and insulation properties. It is commonly used to make linings and insulation for high-temperature equipment.

2, Silicon carbide brick: silicon carbide brick is a high temperature refractory material, with excellent high temperature resistance, corrosion resistance and mechanical strength. It is usually used in the manufacture of high temperature furnaces, electrolyzers and other equipment.

3, High alumina brick: high alumina brick is a kind of high temperature refractory mainly composed of alumina, with good fire resistance, erosion resistance and mechanical strength. It is commonly used in the manufacture of steel smelting equipment, cement kilns and other equipment.

4, Silicate brick: Silicate brick is a kind of high temperature refractory mainly composed of silicate, with good fire resistance and mechanical strength. It is usually used to make furnace linings, heat insulation materials, etc.

5, Aluminum magnesium carbon brick: aluminum magnesium carbon brick is a high-temperature refractory material composed of alumina, magnesium oxide and carbon materials, with good erosion resistance and thermal stability. It is usually used in the manufacture of electric furnace lining, slag mouth and other equipment.

6, Alumina ceramics: alumina ceramics is a kind of high temperature ceramic material, with excellent wear resistance, corrosion resistance, high temperature resistance and insulation properties, can be used to manufacture high temperature equipment lining, insulation materials, etc.

7, Silicon carbide material: silicon carbide material is a kind of high temperature refractory material, with excellent high temperature resistance, corrosion resistance and mechanical strength, often used in the manufacture of high temperature furnace, electrolyzer and so on.

8, Aluminum borate ceramics: aluminum borate ceramics is a kind of high temperature ceramic material, with excellent mechanical strength, chemical stability and insulation properties, in aerospace, electronic components and other fields are widely used.

9,Silicon nitride ceramics: silicon nitride ceramics is a kind of high temperature ceramic material, has good high temperature resistance and mechanical properties, often used in the manufacture of high temperature furnace, optical devices, etc.

10, Aluminum chromate ceramics: Aluminum chromate ceramics is a high temperature ceramic material, with excellent corrosion resistance, thermal stability and mechanical strength, usually used in the manufacture of aluminum electrolytic cells, petrochemical equipment.

In short, refractories with a refractoriness of more than 1700 degrees are an important class of high-temperature fire-resistant materials, which play a key role in industrial production. Different types of materials are suitable for different environments and applications, and enterprises need to choose and use them according to specific circumstances.
