Q:What is the blast furnace ceramic cup called by the refractory factory?

The peak of new materials in various coal, metallurgy, mines, ports, electricity, building materials and military industry, a lot of workpiece and affect production equipment due to wear, wear resistant materials although rarely cause disasters metal workpiece disaster, but the resulting economic loss is immeasurable.

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's the size of the fused zirconia corundum refractories for glass furnace? What are the main kilns? How much is the dosage?

Fused zirconia corundum refractory material of glass fiber kiln quantity is little, generally used in the kiln feed arch furnace flue, where large amount of places are currently using dense zirconium Zr, dense chromium

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:What is the price of concrete self insulation bricks?

Insulation brick prices also have a great relationship with the material and workmanship, such as clay brick price is much lower than high alumina brick, mullite and corundum brick prices will be higher.

Q:What problems should we pay attention to in the use of fused zirconia corundum brick (fused zirconia corundum brick) in glass furnace?

The expansion curves of fused cast AZS brick at 1000 DEG C near a crystal anomaly, its internal changes of ZrO2 crystal are reversible, with large volume change, therefore, products containing ZrO2, should not be used in the temperature of 1000 DEG C, often have sharp fluctuations in the position. When baking the kiln, the temperature can not be too large at 900~1150 degrees centigrade. Generally, the temperature can not exceed 15 degrees /h, and the temperature should be raised steadily. Some parts to prevent the cold, with other brick protection, to prevent explosion.

Q:Ask for help about the phase of refractory material

Binding phase. The binding phase is the phase outside the main crystal phase or the main crystal phase and the sub crystalline phase. The binding phase can be made up of either a fine crystal or a glass phase or a composite of the two. Such as the combination of magnesia brick, magnesia chrome brick, magnesia brick and other basic refractories in phase is composed of crystal matrix; silica brick, clay brick is made of glass phase in the form. When the matrix is formed at high temperature, the liquid phase is low, and the viscosity of the liquid phase is low and the quantity is large, the production and properties of refractory products are essentially controlled by the substrate.

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

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:What is the hardness of corundum refractory bricks?

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