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: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: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?

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: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 equipment is used for producing diamond blanks? How much is the investment?

You'll have to invest about about one million if you want an electric furnace. A power distribution room is easiest to approach one hundred thousand. Electric furnaces, power distribution cabinets and transformers must be around one hundred and ten thousand.

Q:What are the advantages of refractories?

Basic refractory material generally refers to Magnesium Oxide or Magnesium Oxide and calcium oxide as the main component of refractory materials. This kind of refractory material has higher refractoriness and strong resistance to alkaline slag.

Q:What can zirconium sponge do for those industries?

Zirconium metal, also known as sponge zirconium, silver gray metal, the appearance of steel, shiny; melting point 1852 points, sub points, boiling point 4377 density 6.49. Zirconium is easy to absorb hydrogen, nitrogen and oxygen; zirconium has a strong affinity for oxygen; at 1000 DEG C oxygen dissolved in zirconium can make its volume increase significantly. Zirconium is relatively stable in the air; powder zirconium is easy to burn; fine zirconium wires can be ignited by matches; at high temperatures they can be combined directly with dissolved oxygen, nitrogen and hydrogen.

Q:What refractory materials are used in industrial furnaces?

The working conditions of industrial furnaces should first be investigated thoroughly, and the primary and non essential factors affecting the construction of furnace materials shall be analyzed. Focus on thinking, the temperature change condition, temperature bump slag properties, furnace atmosphere, heat insulation, impact wear and other special requirements, to ensure the quality of the life and product.

Q:What is the hardness of corundum refractory bricks?

Such as zirconium corundum refractory brick, chrome corundum refractory titanium corundum refractory brick.
