- Q: Which thermal stability of clay bricks and high alumina bricks is good?
- High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials. 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: Small size black brick can replace refractory bricks for wood burning fireplace?
- Absolutely not. Refractory brick's color looks like that of stone which is also very antique. Black brick can also be pasted on refractory brick. To cope with the use of refractory cement
- Q: refractory bricks of fireclay
- According to the preparation process, it can be divided into bricks, high alumina brick, magnesia brickand so on, such as refractory clay brick, and ordinary brick; according to the shape and size, it can be divided into standard brick and silica?brick, it can withstand all kinds of physical and chemical changes and mechanical action at high temperature; silica?brick can be used as high-temperature building materials and structural material to build kiln and kinds of thermal equipments. Refractory material and fused brick with a certain shape and size are called refractory?brick for short.
- 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 building materials can take the place of clay bricks?
- Transport labor savings, because the foam concrete block itself light weight, such as floor height, consumption, labor savings, about 30% of wages.
- Q: How to prevent the refractory bricks from burning to crack?
- This may result from formula. Prevent the refractory bricks from being overweight. Firstly, sintering agent should not exceed the standard, when sintering, bricks must be well piled to piled bricks, and the bricks must be dry.
- Q: What matters should be noticed when using clay refractory bricks in a glass kiln?
- There are a variety of products for the production of shaped and unshaped refractory clay, such as blast furnace insulation and high alumina bricks. Brick products include refractory clay bricks, plastic materials for overload, refractory clay and high alumina casting materials, etc.. In the amorphous part, if to support the horizontal induction furnace and the straight induction furnace lining, such as refractory clay and high alumina plastic
- Q: what kind of refractory brick is suitable for 1300 degrees converter?
- magnesia-carbon brick, you can also use MgO-Al2O3 castable, it is good too.
- Q: 1200 degrees inside the furnace, lay a layer of refractory brick, what is the temperature outside?
- 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: How much refractory material is required for 1 million tons of coke oven
- This depends on the number of specific cubic, different factory designs different boiler, we need volume to caculate.
