- Q:How to improve the induction furnace campaign, from the promotion of refractory life start
- According to the workpiece, choose the appropriate hardware castable, corundum brick or refractory bricks, etc.
- Q:What is the difference between corundum and high alumina?
- The main component of high purity 99 corundum brick is corundum sand,90 corundum brick is mainly composed of corundum sand and a small amount of Suzhou soil, mullite.
- Q:Wave tile and throwing glaze, tile which good?
- Vitreous tile is all ceramic tile, the material is hard, strong wear resistance, smooth finish is very good, in general, looks very bright. Microcrystalline brick, corundum brick Market said, they really mean bohuazhuan. Because of its low water absorption and high strength and hardness, glazed tile has been widely used. Many hotels, shopping malls and office space are widely used glass tile.
- Q:Application of electric high temperature regulating valve?
- Now, the definition of refractories has not only depended on the degree of refractoriness is more than 1580 degrees celsius. At present, refractory materials refer to inorganic non-metallic materials used in metallurgy, petrochemical, cement, ceramics and other production equipment lining.
- Q:Which is good, glazed brick and whole cast glazed brick?
- The main advantages of all glazed glazed tiles are that they can be very rich and beautiful in texture and pattern, and they are suitable for family decoration, and can choose patterns according to their own family decoration style. Compared to the glazed tile, it has better pollutant discharge performance, and many pollutants are difficult to penetrate into it.
- Q:What are the advantages of refractories?
- The castable refractory is a refractory product with a certain shape after being melted at high temperature by a certain method. Neutral refractory is refractory material which is difficult to react with acid or alkaline slag at high temperature, such as carbon refractory and chrome refractory. Some of the high alumina refractories are also attributed to this category.
- Q:What is the blast furnace ceramic cup called by the refractory factory?
- The refractory bricks, which are suitable for blast furnace conditions, are vitrified by high temperature sintering. They are like a huge cup, so they are called ceramic cups. The name was taken by the French, and the technology was handed down from france!
- Q:What kind of refractory material will be used in the glass kiln?
- High temperature & glass corrosion performance of the brick is slightly lower than that of chromium oxide, also by isostatic pressing forming method, its technical indicators ZrO2>65%, <2.0% porosity, volume density of about 4.25g/cm3, the temperature in E glass is higher than 1370 DEG C have erosion. Used in the E glass melting pool unit kiln glass temperature slightly lower at the end of the transition path, forming the bottom of the pool and forming path path flow tank and bushing support brick etc.. In addition, the dense zirconia brick is used as the backing brick of the dense chrome brick.
- Q:What are the refractory materials?
- Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 93% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, low thermal shock resistance. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, heat shock resistance, resistance to acid slag, widely used.
- Q:What is the hardness of corundum refractory bricks?
- Such as zirconium corundum refractory brick, chrome corundum refractory titanium corundum refractory brick.
