Specifications

Characteristic:
1.High-temperature resistance
2.Lower creep rate
3.High strength
4.Good thermal shock resistance

This product is made by superfine calcined bauxite, additive and high-quality combined clay. This product has good performances of hot flue scouring resistance and corrosion resistance. Its apparent porosity is lower,strength is high and its creep rate is lower, so it means that this product can well keep stability under the load and high temperature.

$clay refractory checker brick for hot blast furnance$

Q:What is the difference between corundum and high alumina?: The main components of high alumina brick are high alumina bauxite, mullite and partial corundum sand.The difference between them lies in the content of alumina and the alumina refractory products with alumina content higher than 48%The content of Al2O3 is higher than 90%, which is called corundum brick.

Q:What's the size of the fused zirconia corundum refractories for glass furnace? What are the main kilns? How much is the dosage?: Fused zirconia corundum brick has a strong resistance to glass liquid corrosion!It is better to fuse the furnace with fused zirconia corundum bricks.Fused zirconia corundum brick, regardless of the size of the furnace, the use of small hundreds of kilograms can be used, depending on the design of the kiln!

Q:How to improve the induction furnace campaign, from the promotion of refractory life start: According to the use of atmosphere, choose the appropriate spraying materials, such as infrared radiation paint

Q:Expansion ratio of lightweight corundum refractory bricks: Now with the production of lightweight foam corundum brick, basically still meters with molding casting, moulding after together with die in the drying room drying in 60~70 C 4 days of release, then the appropriate drying, finally after 1300 and 1550 C firing, the total burning time: 50~60h. Light corundum brick after firing is usually not the size and shape of accurate, so that products after the kiln to mechanical or manual cutting, can be made into a density of 0.8 - 1.3g/cm3, 4MPa compressive strength and porosity, the thermal conductivity of 70%~80% 0.17W/ (M - K), light-weight corundum brick use temperature of 1500~1700 DEG C.

Q:High temperature refractory material?: Now the definition of refractory materials, has not only depends on whether the refractoriness at 1580 DEG. Refers to the current refractories used in metallurgy, petrochemical, cement, ceramics and other production equipment with inorganic non-metallic materials.

Q:What is the difference between T3 refractory bricks and high alumina refractory bricks?: The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)

Q:Can the fire clay be reused?: Refractory soil cannot be reused.Clay refractory soil 1, characteristics and uses: Clay refractory brick is a weak acid refractory material, its thermal stability is good, suitable for hot air furnace, all kinds of boiler lining, and flue, smoke room, etc.. 2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.

Q:What are the main constituents of refractory bricks?: Refractory brick composition is mainly composed of a variety of aggregate or aggregate and one or more kinds of sticky agent composed of mixed powder particles, when used, must be mixed with one or more liquids, mixing evenly, with strong liquidity. Different refractory bricks are different, such as silicon, aluminum, clay and so on:According to the composition of refractory bricks, they can be divided into five major categories, namely, silicon aluminum refractory bricks, basic series refractory bricks, carbon containing refractory bricks, zirconium containing refractory bricks and insulating refractory bricks. Any furnace is not made of only one kind of refractory brick, and it needs different fire bricks to match with each other. The following five categories of refractory bricks are described in detail.

Q:Ask for help about the phase of refractory material: Binding phase. The binding phase is the phase outside the main crystal phase or the main crystal phase and the sub crystalline phase. The binding phase can be made up of either a fine crystal or a glass phase or a composite of the two. Such as the combination of magnesia brick, magnesia chrome brick, magnesia brick and other basic refractories in phase is composed of crystal matrix; silica brick, clay brick is made of glass phase in the form. When the matrix is formed at high temperature, the liquid phase is low, and the viscosity of the liquid phase is low and the quantity is large, the production and properties of refractory products are essentially controlled by the substrate.

Q:What refractory materials are used in industrial furnaces?: The working conditions of industrial furnaces should first be investigated thoroughly, and the primary and non essential factors affecting the construction of furnace materials shall be analyzed. Focus on thinking, the temperature change condition, temperature bump slag properties, furnace atmosphere, heat insulation, impact wear and other special requirements, to ensure the quality of the life and product.
