Q: Zirconium corundum 25 content and 40 content, how to distinguish in appearance?: Fused zirconia corundum brick is pure alumina and zirconia containing silica 65%, about 34% of the zircon sand in electric furnace melting after internalization into moulds cooling and the formation of the white solid, the petrographic structure by zirconium corundum and plagioclase eutectoid and glass phases, from the phase is eutectoid zirconium corundum and plagioclase phase, glass phase filling between their crystallization.

Q: What does refractory consist of?: According to the shape of the product is shaped and unshaped refractory materials two categories, according to the chemical properties of acidic, neutral and alkaline refractory materials three categories, commonly used as refractory material of alkaline and neutral, such as magnesia, alkaline burned magnesia brick, magnesia chrome brick, magnesia calcium brick, high alumina brick, corundum neutral brick, clay brick, including: unshaped castable, ramming material, gunning material, coating material, dry vibration material etc..

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: High temperature refractory material?: Acid refractory with silicon oxide (SiO2) as the main ingredient, commonly used are silica brick and clay brick is siliceous. Products containing more than 93% SiO2, the use of raw materials with silica, silica and other waste brick. Acid slag erosion ability is strong, but vulnerable to the erosion of basic slag, its softening temperature is very high that is close to the refractory, the volume does not shrink after repeated burning, or even a slight swelling, but the thermal shock stability. Silica is mainly used for thermal equipment of coke oven, glass furnace, furnace and other acidic silica brick, according to the physicochemical indexes and SiO2 content can be divided into several levels, mainly brick for glass furnaces and used for coke oven two kinds of brick clay brick. With refractory clay or bauxite clinker as main raw material, containing 30% to 46% of alumina, refractory degrees 1580 to 1770 DEG C, weak acid refractory material, heat shock resistance, resistance to acid slag, wide application Pan, clay brick with refractory clay as main raw material is called ordinary clay brick, made with bauxite clinker as main raw material, the porosity in the clay brick below 17% is called low porosity clay brick. Two kinds of clay brick and according to the physicochemical indexes which were divided into several grades, the price difference between ordinary clay brick and low porosity clay brick greatly.

Q: How do corundum bricks bind?: Each refractory brick is provided with corresponding refractory mud, and corundum bricks are bonded with corundum mud.

Q: What is the difference between T3 refractory bricks and high alumina refractory bricks?: The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)

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 kind of rock is corundum produced?: Aluminum oxide (Al2O3) mineral. Due to Mohs hardness of up to 9, mainly used as high-grade abrasives. The crystal belongs to the three party system, a dolioform six square column, some are needle or plate. Aggregates are massive or columnar. Usually white, gray, yellow and other colors. If a small amount of Cr3+ is red, a ruby is called;

Q: What problems should we pay attention to in the use of fused zirconia corundum brick (fused zirconia corundum brick) in glass furnace?: Casting, casting mouth often appear shrinkage, brick porosity more, the density is lower, so in the brick wall of glass melting, the shrinkage in the kiln direction, if the nozzle outward, when the brick to erosion is very thin, can cause leakage of liquid glass accident. When the flame space is used in the upper part of the bath furnace, the service life is long, and the glass liquid problem can not happen, so the casting mouth is used outwards, and the service life is prolonged.

Q: What can zirconium sponge do for those industries?: Uses: aerospace, military, nuclear reactions, atomic energy, and metal superhard materials, the manufacture of bulletproof alloy steel, can also be used in the reactor uranium fuel coating alloy; zirconium at high temperatures easy to launch electronicProduct characteristics: zirconium metal has very strong corrosion resistance, ultra high hardness and strength
