- Q: How much is the bending temperature aluminum silicon carbide brick for torpedo car
- The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized hot blast stoves.
- Q: What refractory material does cupola lining use?
- It's made of high quality refractory material: 1770 ~ 2000 centigrade.
- Q: What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?
- All the raw materials adding order, mixing time, material and material moisture trapped. 4, the pressure and the volume density of Pei brick and brick Pei size etc..
- Q: The difference between aluminium refractory and magnesia refractory
- Aluminum refractory belongs to neutral refractory material, usually refers to silicon aluminum refractory materials, such as: high alumina brick, clay brick, high alumina castable and other products, the production of raw materials is mainly bauxite.
- Q: What is the difference between T3 refractory bricks and high alumina refractory bricks?
- High aluminum refractory brick brick is all in one type of material classification, the material is AL2O3 high bauxite content above 55%, refractory brick by material into clay bricks, high aluminum brick brick brick corundum brick
- Q: What materials are used for roof insulation?
- The other one is inorganic insulation materials, such as Portland, rare earth insulation, the thickness should be 5 cm or more, up to the high cost of auxiliary materials of construction, to reinforce, new inorganic insulation material, the material thickness, on the line of 2-3 cm, direct smear on the top of the house, without auxiliary material, than the price of wool, high aluminum silicate cotton.
- Q: Which is faster for heat transfer between corundum bricks and high alumina bricks?
- 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.
- Q: Corundum, high alumina and fireclay refractory difference is what
- In fact, they are not consistent with raw materials, corundum refractories can use white corundum, white corundum, brown corundum corundum material, alumina content of these materials is higher than 90%, while the high aluminum refractory material is bauxite, alumina in 90 to less than 70, and clay raw materials the aluminum content is less than 70..
- Q: How to test the aluminium bricks of high alumina refractory bricks?
- Before making bricks, the raw materials are usually tested and tested to see if the aluminum content is up to standard
- Q: Does the chimney have high acid resistance?
- The acid resistant bricks used for chimney are usually made of custom-made trapezoidal acid proof bricks, and the physical and chemical indexes of acid resistant bricks need to be confirmed according to the chimney's actual emission. At this point, you can consult our kerei refractories.
