Q:What is the hardness of corundum refractory bricks?
Corundum refractory brick has good stability against acid and alkaline slag, metal and glass solution. It can be used in oxidizing atmosphere at high temperature or in a reductive atmosphere. The basic material of corundum refractory brick is fused alumina or sintered corundum.
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:High temperature refractory material
Acid refractory with silicon oxide (SiO2) as the main ingredient, commonly used are silica brick and clay brick is siliceous. Products containing more than 93% SiO2, the use of raw materials with silica, silica and other waste brick. Acid slag erosion ability is strong, but vulnerable to the erosion of basic slag, its softening temperature is very high that is close to the refractory, the volume does not shrink after repeated burning, or even a slight swelling, but the thermal shock stability. Silica is mainly used for thermal equipment of coke oven, glass furnace, furnace and other acidic silica brick, according to the physicochemical indexes and SiO2 content can be divided into several levels, mainly brick for glass furnaces and used for coke oven two kinds of brick clay brick. With refractory clay or bauxite clinker as main raw material, containing 30% to 46% of alumina, refractory degrees 1580 to 1770 DEG C, weak acid refractory material, heat shock resistance, resistance to acid slag, wide application Pan, clay brick with refractory clay as main raw material is called ordinary clay brick, made with bauxite clinker as main raw material, the porosity in the clay brick below 17% is called low porosity clay brick. Two kinds of clay brick and according to the physicochemical indexes which were divided into several grades, the price difference between ordinary clay brick and low porosity clay brick greatly.
Q:Expansion ratio of lightweight corundum refractory bricks
Light corundum refractory brick, because of its production methods and the introduction of different additives, there are certain differences in the content of Al2O3, just burn add general light corundum refractory brick and foam and gasification method cannot be made, the content of Al2O3 is generally not more than 99%, with alumina hollow ball manufacturing transfer are corundum brick with high content of Al2O3.
Q:What kind of fused corundum corundum brick should be used for each part of the glass furnace?
AZS33 is the casting of AZS series of the largest, most widely used in tea, to prevent the pollution of liquid glass is excellent. Widely used in the glass furnace pool wall, pool bottom, the upper structure and feeding routes and other parts.
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:What material is used in an iron smelting furnace?
Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on.
Q:Application of electric high temperature regulating valve?
Now, the definition of refractories has not only depended on the degree of refractoriness is more than 1580 degrees celsius. At present, refractory materials refer to inorganic non-metallic materials used in metallurgy, petrochemical, cement, ceramics and other production equipment lining.
Q:What is the main component of corundum?
The name of corundum originates from India and is the name of mineralogy. There are three main variants of corundum Al2O3, which are alpha -Al2O3, beta -Al2O3 and gamma -Al2O3 respectively. Corundum is second only to diamond.
Q:What are the refractory materials?
Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 93% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, low thermal shock resistance. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, heat shock resistance, resistance to acid slag, widely used.
