- Q: What's the reason of cracks in refractory bricks?
- If it is made to refractory bricks,dry in the air naturally for 10 days, then put into the drying furnace, which is certainly better than the brick is put to the furnace directly, this is not easy to crack. After all, the moisture of brick will run in the air. See the semi-finished products (not crack is really no crack), but after drying, it has cracks, this is must because moisture runs quickly in a short time. If it cracks after high temperature heat treatment, the reason is very complicated, such as after high temperature burning, temperature decreases too fast, resulting in a large temperature change, then it cracks. Or in the process of high temperature heat treatment, the internal reaction is intense, and generate some volume expanding materials, resulting in cracks and so on. Mullite Petrochemical reaction, spinel reaction and so on, the reactions of a lot of materials are the volume expansion
- Q: Scheme of cement kiln replacing 40 meter refractory brick kiln
- If only replace refractory bricks, it just needs three days under the condition of 200 degrees. It will be simpler if there is only free water in the refractory brick (no pouring material).
- Q: How much is the silica powder in refractory bricks.
- It's not easy to construct, also need to consider the technical and economic indexes, DH3, 1 kg silica powder replaces 1 ~ 3 kg cement, which is the reason why silicon powder was not used and spreaded in concrete in past, choose some silica power fume. In general, with the smoke escaping by special capture device for collecting and processing To determine the mixing method of silica powder, when mixing silica powder, you should find out the optimal dosage in order to obtain the best results, as the study, the content is 5% ~ 30%, H, the mixing of super high strength concrete, use same amount of silicon powder to replace equal cement to main same fluidity, Microsilica or Silica Fume, it is mainly according to the design requirements, and does not reduce the amount of cement, sand and stone to adjust the optimal dosage of water reducer, when deciding the best mixing amount of silica fume, the concrete is too sticky, most use naphthalene water reducing agent.
- Q: Why is the house made of refractory bricks not warm in winter
- Refractory bricks are not used in the house, but used in a large boiler inner
- Q: The advantages of using alkalinty refractory brick?
- Magnesia chrome and other spinel refractories alkalinity refractories; (2) the alkalescent chrome magnesite refractories, alkaline solvent resistance is strong, usually refers to the magnesia refractory material, dolomite brick and calcareous refractory materials, dolomite refractory materials and lime refractory materials, acid flux or acid refractory chemical reaction. Mainly used in alkaline steel furnace and non-ferrous smelting furnace. Alkaline refractory material at high temperature for alkaline slag. Mainly as the following categories, but the acid slag, forsterite refractories and magnalium: (1)strongly alkaline magnesia brick, magnesia carbon brick and cement kiln
- Q: How are shale porous bricks and clay porous bricks distinguished?
- Weathering resistance is better than clay brickDue to differences in clay shale and its performance, the national standard requires shale weathering properties than clay bricks.
- Q: How to wipe off the white paint on the refractory brick (red).
- Cover the wall gap with tape. . Then paint the bricks. Finally, tear the tape off. .
- Q: How many squares of a ton refractory bricks?
- About 2 tons , general one square clay brick is about 2 tons, from 2, one square corundum brick or magnesia bricks can reach 3 tons, it should say one square is how many tons. if it is high aluminum, then see the content of aluminum. It mainly sees what refractory bricks, because the volume and density of refractory bricks are relatively large.2 tons to 2
- Q: Why is the brick instead of solid clay brick
- Shale is a sedimentary rock weathering hard substance, which is relatively hard, mainly from clay minerals and small clay particles into the pressure, cementation, weathering after the formation of hard substances, such substances are relatively hard.
- Q: With what three clay brick clay brick with six holes under what circumstances?
- Local material. The two kinds of pumping rate are different, the thermal resistance is different, the volume density and thermal conductivity have some differences, but also by the designer's habits, and local production, the impact of the market.
