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?: 5. fused zirconia corundum brick (AZS brick)The chemical composition of the brick is ZrO234%, Al2O349.2%, SiO215.9%. The bulk density is 3.85g/cm3, and the main uses are the melting part, the burner brick and the feeding port brick.6. fused chromium corundum brickThe chemical composition of the brick is Cr2O328.3%, Al2O358.3%, MgO, Fe2O35.2%. The bulk density is about 3.4g/cm3. A flue interface brick that is mainly used at the entrance of the heat exchanger.

Q: Is it good for your cupola to use that kind of refractory, high aluminum brick, clay brick or red silica?: I suggest you go back to learn Chinese at primary school, and then ask questions again.Don't consider the cost, andalusite sillimanite brick well. But I don't have a cupola. It's too expensive to buy.

Q: Sillimanite brick: 1 、 high temperature resistant abrasion resistant coating;2, sillimanite refractory fireball;3, styrene kaolin - sillimanite insulation refractory products;4. High strength unshaped refractory material is used for building high temperature kiln;5 、 rare earth composite silicon carbide material;6, a composite insulation high-temperature refractory coating;7 、 refractory castable with high temperature self strengthening effect.

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.
