- Q:How to repair the boiler?
- What kind of boiler, the external wall or the furnace arch, the smoke wall, the material: High-alumina cement, refractory brick, refractory clay, knife brick
- Q:What are the differences between fireclay brick and high alumina refractory brick?
- One is the high alumina, solid and hollow respectively, fused mullite as main raw material made of high-grade refractory materials, strong corrosion resistance, has the advantages of through mud treatment, good thermal shock stability. Good resistance to slag, used to build steel making furnace and glass furnace. High alumina brick is a kind of refractory material. Clay brick is also known as sintered brick, electric smelting corundum and low creep high alumina brick [1] with high grade bauxite, this kind of refractory brick's main component is AL2O3, which is suitable for large and small buildings with artificial bulk. High thermal stability. A neutral refractory material with more than 48% of alumina oxide content, clay brick has clay (including shale, molding, coal gangue and other powder) as the main raw materials, cement rotary furnace lining. The product has a small high-temperature creep, one is clay. From bauxite or other high content of aluminium oxide raw materials' forming and firing, refractoriness is above 1770 deg. High R.U.L and medium-sized hot-blast furnace is different firstly in the material, forming from drying and roasting
- Q:What is the size of mechanism brick and general refractory brick?
- The ordinary refractory brick is 230mm long, 53mm thick; red brick is 240mm long, 115mm wide, 65mm thick,
- Q:Can refractory bricks be used to build a house?
- Refractory brick can be used to build houses, but you can not use ordinary cement to build, the cost is 3 times than that of ordinary brick.
- Q:When using high alumina refractory brick, what are the reasons leading to the decline of the performance of high alumina brick?
- The excess air coefficient is controlled in 1, in order to prevent producing water cracks in the production of high aluminum refractory brick from, control the water absorption of 2 grade clinker of bauxite with high alumina below 4%-5%. 1-1,the water absorption of the tube mill should also be controlled below 6%, and adjust thermotechnical, making the high alumina refractory brick burning be in the stable weak oxidizing atmosphere. should be 2
- Q:can diatomite?brick be used as thermal insulation refractory brick?
- yes, it has good thermal insulation the raw material is cheap, diatomite?brick is a kind of thermal insulation refractory brick with good performance.
- Q:Why should the clay bricks be watered first when they are building masonry walls?
- Therefore, in order to facilitate the operation, so that the mortar has a suitable hardening and strength growth environment, to ensure the quality of masonry, bricks must be watered before use wet.
- Q:Can refractory bricks be used when it cracks for 1cm
- 3, If the crack is caused by burning or drying, then it can't be used. While if the carck is caused by refractory brick molding, it still can be used. 4, the crack is caused by refractory bricks raw materials.
- Q:What building materials can take the place of clay bricks?
- Foam concrete block is a new type of environmental protection material, the state will avoid the wall change fund, and the red brick construction units must be turned over to 8 yuan per square metre of the wall change fund.
- Q:Are refractory bricks, burner block and thermal insulation brick the same? Are they the same thing?
- the proportion of raw materials of refractory bricks and thermal insulation bricks. chain of various types of products
