- Q: How to use fire-resistant soil?
- In fact, the refractory soil is not strong. Refractory soil is clinker, there is no strength, also known as "blade mud", he is used as filling materials, the use of thickness generally not more than 3mm. Therefore, the furnace insulation can not be done.Civil boiler interior insulation, you can use "high aluminum cement", also known as refractory cement on it.
- Q: which kind of refractory is used in golden smelting furnace? How about his using temperature
- generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.
- Q: Using what kind of melting aluminium furnace refractories is more appropriate?
- If it's the ordinary, you can use high aluminum refractory brick with general clay, GB/T 3994-2005 clay heat insulation refractory brick. If you need these with good material, there is high alumina thermal insulation refractory brick, GB/T 3995-2006 high aluminum heat insulation refractory brick, models have A13 and material is the alumina, A13 50 u, high insulating brick B5.Intermediate insulating brick B2, etc. Dolomite brick: good hang kiln performance, good erosion resistance, but brick is usually without f - CaO, hydration, and difficult to transport and storage, less used in the production. Magnesia-chrome bricks: good hang kiln, used in calcining zone. The disadvantage is that its thermal shock resistance is poor and plus hexavalent Cr is toxic, the production and use of magnesite chrome bricks in international countries gradually reduce. Now unit using the brick find replacements as soon as possible.
- Q: How to make fire resistant materials for building stoves
- Legend of the old version has been upgraded, or can not enter the server, is not legend stopped?
- Q: Selection of refractory materials?
- Inorganic non-metallic material with a refractoriness of more than 1580 degrees. Refractoriness refers to the temperature of a sample of a refractory cone, which is resistant to high temperature without softening, and does not soften and melt down. Refractory materials are associated with high temperature technology, which originated roughly from the middle of the bronze age. In the Eastern Han Dynasty has made China kiln firing porcelain material and with fireclay refractory sagger. In the early twentieth Century, refractory materials were developed towards high purity, high density and ultra high temperature products. At the same time, unshaped refractory materials and refractory fibers without firing and energy consumption were developed. With the development of modern technology, atomic energy, space technology, new energy technology, refractory material having high temperature resistance and corrosion resistance, thermal shock resistance, erosion resistance and other comprehensive excellent performance has been applied.
- Q: What are the requirements for the performance of refractory materials?
- Refractory materials should have very high refractoriness, high temperature heat load and resistance to softening, melting; with high volume stability, resistance to high temperature and heat load, volume shrinkage and only uniform expansion; high strength at room temperature and high temperature strength, high load softening temperature, under the joint action of heat load and heavy load, no loss of strength, creep collapse; Electric furnace analysis should have good resistance to thermal shock, resistance to rapid temperature changes, no crack, not flaking; with excellent slag resistance.
- Q: What is the difference between the fire?rating and the fire resistant level of the fire-fighting equipment?
- Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. Fire resistance rating of the building is divided into four levels. Standard of fire resistance rating is determined by the combustion performance and fire resistance of the main housing member. Level one or two are in accordance with the Article 1.0.2 in this specification.
- Q: how does the fire endurance of first rate fire resistant window?
- Not less than 1.5 hours
- Q: Fefractory of aluminium oxide.
- Do you mean the alumina hollow ball brick? We can exchange private messages in specific.
- Q: What's the commonly used refractory material for ladle?
- Commonly used types of refractory material for ladle are as follows: high-alumina brick, clay brick, magnesia-carbon brick, aluminum carbon brick, magnesia chrome brick, spinel brick, corundum brick, high alumina castables, aluminum silicon carbide carbon castables, refractory castables for ladles, magnesium castables, magnesia chrome spray coating, dry vibration materials, etc. Hope it's helpful for you!
