FAQ

What's the maximum temperature that the refractory ceramic fiber cloth can endure?

While the refractory ceramic fiber cloth is different in high temperature resistance, and in general it can endure the high temperature of more than 1000℃. Ceramics in daily use and art ceramics: Bone china and Guangdong chinaware can generally endure the highest temperature of 1100℃. Jingdezhen porcelain and ceramics: They can generally endure the highest temperature of 1280℃-1340℃, and some special ones can endure the highest temperature of 1400℃. Industrial ceramics: Some of them can endure the highest temperature of about 2600℃. (alumina ceramics: their melting point is 2050℃, and boiling point is 3000℃).

The classification of fire-resistant material

There are various refractory materials classified according to the chemical properties of material: Min< manufacturing technique: neutral refractory materials, pipes, etc. Standard model: baidu.hiphotos;8 simatic carbon composite refractory material zirconia based refractory material special fire-proof material 6; or a acute angle of 50～70° and material forms. 3.

What are the specifications of refractory kilns ?

Rotating equipment is widely used in mechanical, physical or chemical treatment of solid materials in building materials, metallurgy, chemical and environmental protection industry. Such equipment is called rotary kiln. The best materials are magnesia-chrome bricks, unfired magnesite-chrome bricks, silmo bricks, magnesia-alumina spinel bricks, magnesia calcium zirconate bricks, iron magnesia bricks and castables.

What's the refractoriness and how to measure the refractoriness?

Bottom each side length is 8 mm and upper side length is 2 mm. Under a certain temperature-rising speed, when heating, refractory's resistance to high temperature from melting is called refractoriness. The properties of cross section into an equilateral triangle and height is 30 mm. When it bends down until the vertex and chassis contact temperature is the refractoriness of sample. It bends due to the influence of its weight. Make the will-measured material into standard pyrometric cone.
