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:What are the main constituents of refractory bricks
High alumina refractory brick, high alumina refractory brick mineral composition for corundum, mullite and glass phase, its content depends on AL2O3/, SiO2 ratio, as well as the kind and amount of impurities, AL2O3 content can be divided into refractory brick grade. The raw materials are high alumina and sillimanite natural ore. They are also made of fused alumina, sintered alumina, synthetic mullite and calcined alumina in different proportions with clay. It is produced by sintering process. But the products are casting brick, brick, brick fused grain and unshaped refractory brick. High alumina refractory brick is widely used in iron and steel industry, non-ferrous metal industry and other industries.
Q:How much is a refractory brick?
This question is too general, refractory bricks according to the use of the environment and industry, there are a variety of materials, a variety of specifications, prices vary greatly.
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.
Q:What kind of refractory material will be used in the glass kiln
High temperature & glass corrosion performance of the brick is slightly lower than that of chromium oxide, also by isostatic pressing forming method, its technical indicators ZrO2>65%, <2.0% porosity, volume density of about 4.25g/cm3, the temperature in E glass is higher than 1370 DEG C have erosion. Used in the E glass melting pool unit kiln glass temperature slightly lower at the end of the transition path, forming the bottom of the pool and forming path path flow tank and bushing support brick etc.. In addition, the dense zirconia brick is used as the backing brick of the dense chrome brick.
Q:What refractory materials are adopted in each part of the blast furnace
Bosh temperature reaches 1600~1650, high alumina brick, corundum brick or silicon carbide brick. The upper hearth tuyere zone near the temperature at 1700~2000 Deg. C, the use of sillimanite brick, corundum and silicon carbide refractory filler, Shi Mozhi. Bottom temperature at 1450~1500 Deg. C, the use of graphite bricks and microporous carbon brick, now also used corundum brick, Gang Yumo brick and synthetic mullite brick.
Q:How do corundum bricks bind?
High temperature bonding clay can be used for bonding masonry
Q:What are the advantages of refractories?
The castable refractory is a refractory product with a certain shape after being melted at high temperature by a certain method. Neutral refractory is refractory material which is difficult to react with acid or alkaline slag at high temperature, such as carbon refractory and chrome refractory. Some of the high alumina refractories are also attributed to this category.
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?
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.
