- Q: What is the name of the white clay refractory brick
- Kaolin
- 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: What's the difference between a high aluminum brick and a clay brick, two?
- Lightweight high alumina bricks are usually made of high alumina bauxite clinker with a small amount of clay. After grinding, the bricks are poured and shaped in the form of slurry by gas or foam method. They are fired at 1300~1500 DEG C. Sometimes industrial alumina can be used instead of some bauxite clinker. Used for lining and insulation of masonry kilns, as well as for areas where there is no strong, high temperature molten material erosion and erosion. When contacting the flame directly, the surface contact temperature shall not be higher than 1350 degrees centigrade.
- Q: What are the main raw materials of refractory brick and runner brick?
- Types of refractory bricks are divided into low-grade and high-grade. generally, siliceous, semi siliceous and high aluminous runner brick brick have higher requirements. If it needs to contact melting in high temperature molten steel directly, then it is high alumina(the main raw material is clinker of bauxite with high alumina, corundum( brown corundum and white corundum), the refractoriness is high, lower than 1580 DEG C temperature, but the actual using temperature reaches 1630 DEG C
- Q: Are buildings allowed to use red bricks?
- Clay brick is forbidden to be used by the state, whether red or green. Red and cyan are just the difference between making techniques. Now also produces appearance and clay sintering, red brick like silicate sintered brick can be used.
- Q: Can thick steel plate be used instead of the furnace inside the refractory brick?
- It depends on the temperature. The steel plate is a kind of heat conduction material which hasn't heat insulation, which should be based on the working environment.
- 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: Do refractory bricks insulate heat?
- It can not be generalized, generally, the insulation performance of clay is not good, but the hollow is good, such as light mullite bricks have good insulation. it depends on what kind of refractory brick
- Q: What is the perservation method for refractory bricks used for cement kiln?
- The hydration resistance ability is better than the alkaline materials, 1 years will be no problem if the environment is good, alkali-resistant bricks used in cement kiln brick refractory brick (magnesia-chrome brick, the preservative time will be longer, the remaining products should also be moistureproof. No matter what refractory materials, phosphate brick. If the package is complete, it must be stored in a dry and rain-proof environment, silmo brick. Anti-stripping alumina brick, if is not immediately used, it's necessary to take measures of moisture proof, such as spinel brick must be moisture-proof
- Q: What is the raw material for the production of refractory bricks?
- Refractory raw material, sodium silicate as a binder, and lightweight aggregate, magnesium sand, magnesia calcium. Magnesium Oxide, bauxite, and then lightly burn: Hard refractory clinker
