Q: What is the main component of corundum?: Corundum is the main component of Al2O3, often containing trace impurities such as Cr, Ti, Fe, V and so on.

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: Expansion ratio of lightweight corundum refractory bricks: Now with the production of lightweight foam corundum brick, basically still meters with molding casting, moulding after together with die in the drying room drying in 60~70 C 4 days of release, then the appropriate drying, finally after 1300 and 1550 C firing, the total burning time: 50~60h. Light corundum brick after firing is usually not the size and shape of accurate, so that products after the kiln to mechanical or manual cutting, can be made into a density of 0.8 - 1.3g/cm3, 4MPa compressive strength and porosity, the thermal conductivity of 70%~80% 0.17W/ (M - K), light-weight corundum brick use temperature of 1500~1700 DEG C.

Q: Can the PE sintering plate dust collector be suitable for dust removal in the coking plant?: Do not know where the coking plant do dust treatment, processing conditions are different, the dust collector is not the same

Q: What refractory materials are adopted in each part of the blast furnace?: Bosh temperature reaches 1600~1650, high alumina brick, corundum brick or silicon carbide brick. The upper hearth tuyere zone near the temperature at 1700~2000 Deg. C, the use of sillimanite brick, corundum and silicon carbide refractory filler, Shi Mozhi. Bottom temperature at 1450~1500 Deg. C, the use of graphite bricks and microporous carbon brick, now also used corundum brick, Gang Yumo brick and synthetic mullite brick.

Q: What is the hardness of corundum refractory bricks?: Such as zirconium corundum refractory brick, chrome corundum refractory titanium corundum refractory brick.

Q: Is liquid phosphoric acid two aluminum hydrogen flammable?: Two aluminum liquid hydrogen phosphate using spray paint, cement, refractory castable and binder for foundry industry, mainly used in refractory industry corundum, chromium corundum nozzle coal water slurry gasifier with chromium aluminum zirconium corundum brick production.

Q: What are the refractory materials?: Basic refractories in Magnesium Oxide and calcium oxide as the main ingredient, commonly used is brick. Magnesium Oxide 80% to more than 85% containing magnesia brick, has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and high temperature equipment.

Q: Can the fire clay be reused?: According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, ordinary brick, specific rotation. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature.

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.
