A3 Apart from entire Chinese market, the US, Russia, Japan, Korea, Australia and some Southeast Asian Nations.
- Q: Whether the cement kiln refractory bricks belong to hazardous waste or not?
- No, there is no harmful gas produced, and it will not pollute the ground.
- Q: What kind of coal should be used to burn refractory brick? and how many calories smoke is suitable?
- It can't be the surface of coal, at least it is coal seed.
- Q: air-cooled razheng times of magnesia-alumina spinel refractory bricks
- The ingredients are magnesium, oxygen, and aluminum. the components of spinel refractory can be magnesia-alumina spinel with excessive aluminium oxide, or magnesia-alumina spinel with excessive magnesium oxide. excessive magnesium oxide and aluminium oxide can form magnesia-alumina spinel in above 1700 degrees.
- Q: Are there any good improvement measures for the always collapse of the previous vaulted tunnel kiln built by refractory bricks?
- Volume shrinkage, uneven shrinkage and expansion of part, long-term high-temperature processing crystal type changes, calcium and other substances forming the refractory brick is Magnesium Oxide. Also the temperature changes quickly, and belongs to the crystal compound, silicon aluminum, sealing material's selection should be pay attention to
- Q: Shale brick and clay brick? Answer before you know it
- Is the shale as raw material for high temperature baked bricks using shale and coal gangue, shale sintered porous brick, hollow shale brick, shale brick, high insulation, water wall and other types of modular brick.
- Q: What is the refractory brick in silicious model?
- Adding appropriate amount of mineralized agent to promote the transformation of quartz in the body into phosphorus quartz. Smaller coefficient of thermal expansion. Also used in high temperature bearing part of hot blast stove and acid open hearth furnace, refractory materials and ceramic kiln, kiln vault and other load-bearing parts, thermal shock resistance variation. High temperature strength. the glass furnace is burnt in 1430 to 1350 degrees Celsius in the reducing atmosphere. use natural silica as raw materials. True density 2. more than 93% of silica content. generally there is no crystal type transformation above 600 degrees celsius. With acid slag erosion and sediment chamber regenerator performance, soaking furnace, open hearth furnace. there is more crystal type transformation below 600 degrees celsius. mainly used in coking chamer of coke oven and partition of firebox. acid refractory material made of high thermal shock resistance, large volume change, square quartz and a small amount of residual quartz and glass box . Long term use at high temperature without deformation
- Q: The making process of clay brick
- Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks. In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.
- Q: What are the type, location and the physical and chemical effects of the refractory brick used in the cement rotary kiln?
- But most people use high alumina brick or clay brick, G6 refractory brick. The specific masonry location, such as G4 refractory brick, standard brick, T38, OD, T39, according to the length of your rotary kiln, many kinds of refractory bricks are used in cement rotary kiln, the specific size of the inner diameter should be calculated in detail
- Q: What kind of refractory material is used in the furnace when the boiler reaches more than 1200 degrees?
- except refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and so on.
- Q: Can porous clay bricks be made of 12 walls to bear weight?
- Porous brick using cement as binder, and sand, stone (aggregate) by adding water and mixing, molding and maintenance made with a plurality of rows of holes of the concrete products; after ordinary and lightweight aggregate concrete small hollow block and a variety of new wall materials.
