- Q: I am a student of refractory materials. I would like to know the general rank of national refractory materials company
- GL-60, high temperature daub, rock wool pipe shell, high quality magnesia brick, high alumina castable explosion-proof, high strength steel fiber steel fiber reinforced corundum castable, refractory castable, alkali brick, sillimanite brick, high alumina brick insulation level, wear-resistant castable, refractory castables for large power plant, silicon mullite brick, alkali resistant castable, blast furnace iron trough castable, super high alumina brick, magnesia spinel brick, castable, magnesia chrome brick, high alumina low cement castable, rock wool board, aluminum corundum brick, magnesia brick etc..
- Q: What kind of refractory material will be used in the glass kiln?
- 3. standard zirconium brickThe content of ZrO2 in the brick is about 66%, and the bulk density is 3.7g/cm3, which has better thermal stability and anti stripping property. The use of erosion serious investment outlet area and after the parapet wall in the powder melting furnace, observation hole brick and pathway of flame space and roof parapet wall brick, brick burner. But there are also AZS burner brick with mullite brick for brick kiln and transition two side clearance brick etc..
- Q: Is it good for your cupola to use that kind of refractory, high aluminum brick, clay brick or red silica?
- The high aluminum clay brick is slightly more stable and can be used!
- Q: Sillimanite brick
- After calcination at high temperature, sillimanite transforms to mullite and free silica. Generally use the firing process and production of high temperature mud casting method. Its physical and chemical properties are better than those of aluminum bricks, the refractoriness is 1770~1830 degrees, and the load softening point is 1500~1650 degrees centigrade. The utility model is mainly used for the forming of a liquid hole in a glass furnace, a lining of a blast furnace, a furnace throat and a ceramic industrial kiln tool.
- Q: What refractory materials are adopted in each part of the blast furnace?
- The furnace throat is a part of the direct impact and friction when the burden drops, and the high density and high alumina brick is usually adopted. The upper and middle shaft temperature is only 400~800 degrees, the parts with high alumina brick and sillimanite brick. The lower part of the shaft due to high temperature and dust by scouring and alkali metal vapor erosion, so the requirements for the slag resistance, alkali resistance and high temperature resistance, wear resistance of high quality clay brick, high alumina brick, carborundum brick or corundum brick. Belly temperature reaches 1400~1600, and slag, steam erosion, erosion and corrosion is strong, therefore, the silicon carbide reaction bonded silicon carbide brick.
