- Q: What does refractory consist of?
- According to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.
- Q: What is the blast furnace ceramic cup called by the refractory factory?
- The peak of new materials in various coal, metallurgy, mines, ports, electricity, building materials and military industry, a lot of workpiece and affect production equipment due to wear, wear resistant materials although rarely cause disasters metal workpiece disaster, but the resulting economic loss is immeasurable.
- 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: What refractory materials are used in industrial furnaces?
- Refractory materials use high temperature function to master all kinds of refractory material function, especially high temperature use function. Selection should give full play to its advantages, and from the furnace structure, masonry and protection to overcome its shortcomings.
- Q: What is the standard classification of high alumina bricks and high alumina bricks?
- Refractory brick is non-metallic materials can be classified according to a kind of inorganic material, high aluminum brick, clay brick, magnesia brick, corundum brick, mullite bricks, silicon carbide materials such as brick, high alumina brick is used as a relatively wide range of products in accordance with the refractory brick high alumina refractory materials by high aluminum brick is generally divided into Al2O3 content three: I - II - >75% Al2O3 content; the content of Al2O3 is 60 ~ 75%; III - Al2O3 content from 48 to 60%.
- 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: High temperature refractory material?
- Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, the refractory material used for special occasions.
- 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: 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.
