Q:What refractory materials are adopted in each part of the blast furnace
The furnace throat is a part of the direct impact and friction when the burden drops, and the high density and high alumina brick is usually adopted. The upper and middle shaft temperature is only 400~800 degrees, the parts with high alumina brick and sillimanite brick.
Q:What's the size of the fused zirconia corundum refractories for glass furnace? What are the main kilns? How much is the dosage?
The fused zirconia corundum brick is made up of 30% ~ 41% zirconia two in the alumina burden. The main mineral compositions are corundum, zircon and glass phase. The main varieties are fused (or cast) zirconium corundum brick (also known as AZS casting brick) and sintered zirconia corundum brick. Generally speaking, zircon corundum brick means sintered zirconia corundum brick. It is made from alpha -Al2O3, partially stabilized zirconia and zircon corundum clinker, which is prepared by proportioning and molding at 1700~1750 DEG C and then sintered at two. The sintered zirconium corundum brick has a strong resistance to molten glass, and its thermal shock resistance is stronger than that of fused zirconia corundum brick. It is mainly used as lining of glass furnace and induction furnace, as well as steel rolling furnace, slide rail, etc..
Q:What's the jade stove for?
Is it a furnace made of corundum or a furnace for smelting corundum?Corundum brick stove is commonly used as a refractory material sintering furnace, can be fired refractoriness in refractories, below 1700 degrees such as brick, corundum brick, brick, alumina hollow ball and so on
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:Can the PE sintering plate dust collector be suitable for dust removal in the coking plant?
The sinter plate dust collector is also called plastic plate dust collector. The utility model has the advantages that the utility model can adapt to various complicated working conditions, the dust removal rate is 99.99%, the utility model has the advantages of long service life, stable operation, high temperature resistance, and the utility model is a leading dedusting equipment in china.
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:Can the fire clay be reused?
Refractory soil cannot be reused.Clay refractory soil 1, characteristics and uses: Clay refractory brick is a weak acid refractory material, its thermal stability is good, suitable for hot air furnace, all kinds of boiler lining, and flue, smoke room, etc.. 2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.
Q:How do corundum bricks bind?
High temperature bonding clay can be used for bonding masonry
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.
