The refractoriness of Mullite Jm26 Insulating fire brick can reach above 1790℃. The starting temperature of softening under load is 1400. The compressive strength at room temperature is 3-8MPa. Good thermal shock resistance. There are two kinds of sintered laystone bricks and fused mullite bricks. Sintered mullite brick is made of high alumina bauxite clinker as the main raw material, adding a small amount of clay or raw bauxite as a binder, and is made by molding and firing. Fused mullite bricks are made of high alumina, industrial alumina and refractory clay as raw materials, and charcoal or coke fine particles are added as reducing agents. The crystallinity of fused mullite is larger than that of sintered mullite, and its thermal shock resistance is better than that of sintered products. Their high temperature performance is mainly determined by the alumina content and the homogeneity of the mullite phase and glass distribution.
Mullite Jm26 Insulating fire brick is made of high alumina bauxite clinker and a small amount of clay. It protects clay resources well, so no
The appearance of Laishi thermal insulation bricks is the product of modern technology. In the past, aluminum was something that could only be used, but modern technology has made aluminum a resource that can be used to produce various products.
JM series mullite bricks can be used at a temperature of 1300 degrees to 1600 degrees for different materials, and the body density can be between 0.6, 0.8, 1.0, and 1.2 according to user requirements. It is used in high-temperature kilns to directly contact the flame, with good heat preservation effect and pressure resistance. High strength and low thermal conductivity. It is suitable for heat preservation of electric kilns, various high temperature rotary kilns, tunnel kilns, hydrogen gas kilns, etc. The crystallinity of fused mullite is larger than that of sintered mullite, and its thermal shock resistance is better than that of sintered products. Their high temperature performance is mainly determined by the alumina content and the homogeneity of the mullite phase and glass distribution. Jm26 Insulating fire brick are mainly used for hot blast stove top, blast furnace shaft and bottom, glass melting regenerator, ceramic sintering kiln, dead angle lining of petroleum cracking system, etc.
Mullite Jm26 Insulating fire brick product features
1. Because the mullite thermal insulation brick has the characteristics of low thermal conductivity, it has a good thermal insulation effect, which can make the thickness of the furnace wall thinner. ;
2. The mullite thermal insulation brick has the characteristics of low thermal melting and low thermal conductivity, which makes the light mullite brick series products accumulate little heat energy, and the energy saving effect is obvious in the intermittent operation kiln.
3. Low impurity content has very low oxide content such as iron box alkali metal, so the refractoriness is high, and the high aluminum content makes it maintain good performance under reducing atmosphere;
4. The high temperature compressive strength of mullite insulation brick ensures the strength and stability of the masonry.
5. The appearance and size of mullite insulation bricks are accurate, which can speed up the masonry, reduce the use of refractory mud, and ensure the strength and stability of the masonry, thereby prolonging the life of the lining;
6. Mullite polylight bricks are easy to process and can be processed into special shapes according to the needs of customers, thereby reducing the number of bricks and joints.
