Q:What are the refractory materials?
Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, there are refractories for special occasions.
Q:What refractory materials are used in industrial furnaces?
Masonry parts using his cooperation because of the repair or overhaul time, labor, materials, fuel consumption is great. Some of the other, a stove overhaul, will inevitably affect the other parts of life. Therefore, the selection of materials should be thinking of various parts of masonry of life, the habit.
Q:How much is a refractory brick?
There are many kinds of refractory bricks, you have to look at what is material, the material is not the same, the price is not the same, clay brick is the cheapest, probably hundreds of dollars a ton, and corundum brick a ton of several money, silicon carbide, silicon nitride, and more expensive. And this thing is generally on t sell, the price is by a single block after conversion.
Q:Is liquid phosphoric acid two aluminum hydrogen flammable?
Liquid phosphoric acid two hydrogen aluminum features: easy mixing, molding, especially suitable for field construction, so liquid phosphoric acid two hydrogen aluminum is not flammable
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:Which is good, glazed brick and whole cast glazed brick?
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:What kind of fused corundum corundum brick should be used for each part of the glass furnace?
In addition to AZS33# and AZS same co crystallization in vitro, 36#AZS due to the increase of chain like zirconia brick more crystals, while the glass phase content is low, so 36# AZS corrosion resistance has been further enhanced, so is suitable for the rapid flow of molten glass or high temperature region.AZS36 s is an excellent product in the AZS series. It has high resistance to glass liquid erosion and low pollution. It is usually used in the key parts of the glass furnace, such as the pool wall near the hot spot.
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: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 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.
