Magnesite chrome block uses quality magnesia and chromic oxide as the raw material, molded through high press and fired in the high temperature. magnesia chrome bricks have features of large crystal and high direct bonding rate. and magnesite chrome fire bricks have good cracking resistance and good acid slag erosion resistance with low alkaline property. magnesite chrome block is the ideal lining brick material for finery out of furnace, electric furnace, glass furnace, melting furnace and
Magnesia bricks for sale are basic refractory bricks materials whose MgO content are more than 90% and adopt periclase as the principal crystalline phase. Generally, this kind of refractory bricks can be classified into 2 types by the two bonded methods, sintered bonded and chemically bonded.
Oct 26, 2015 · As fireclay brick is relatively cheap and its raw materials are widespread, it is the most common type of refractory brick and used widely in most furnaces, kilns, stoves, regenerators, etc.
230x114x65mm Size Magnesia Bricks Common Magnesium Chrome Brick Square Shape . Description: It is made with sintered magnesia and refractory level chrome ore as raw materials. The space between refractory grains is bonded wi
formation in the brick and can subsequently lead to disintegration of the whole brick. The disintegration occurs as the magnesium hydroxide (brucite) consists of powder which additionally has a bigger volume compared to the original magnesia. Generally, magnesia used in lime kiln refractory is either of dead burnt or fused type, which is
Magnesia chrome brick is mainly used in the metallurgical industry, such as the construction of open hearth, furnace top, furnace refining furnace and various non-ferrous metal smelting furnace. The high temperature section of ultra high power electric furnace is made of fused magnesia chrome bricks.
Magnesia-chrome bricks are refractory products containing magnesium oxide (MgO) and chromium oxide (Cr2O3) as the main components, and periclase and spinel are the main mineral components. This type of brick has high refractoriness, high temperature strength, strong resistance to alkaline slag, excellent thermal stability, and certain adaptability to acidic slag.
Magnesia brick is an important high-grade refractory brick and is mainly used in open hearth furnace, oxygen converter, electric furnace and non-ferrous metal smelting. Corundum brick refers to a kind of refractory brick with AL2O3 content of not less than 90% and corundum as main phase, which can be divided into sintered corundum brick and fused corundum brick.
Rebonded Magnesia Chrome Bricks Applications. Rebonded magnesia chrome bricks and semi rebonded magnesia chrome bricks are widely used in parts of metallurgical furnaces where corrosion is severest, such as out furnace refinery equipment, AOD furnace tuyere, RH furnace vacuum chamber lower part groove and dipping pipe, VOD furnace slag line, heavy nonferrous metals converters tuyere zone
Application: They are widely used in the basic zone of metallurgical furnaces, nonferrous furnaces and regenerator of glass furnaces. Description. Magnesia Refractory Bricks,Basic refractory magnesium oxide content in more than 90%, the main crystalline phase to pericase. Magnesia brick have high refractoriness,alkali slag good performance
Magnesite bricks are alkaline magnesite refractory materials. Magnesium oxide content of the magnesia bricks is more than 90%, and the periclase is the main crystal phase, which directly effects the performance. Such magnesite refractory is featured with high refractoriness, alkaline slag resistance, high refractoriness under load.
lime kiln, non-ferrous metallurgical furnaces, open heart furnace, iron mixer and EAF of steel-making, and also ferro-alloy furnace, etc The bricks with MgO 95% or more in content take the secondary-burning dead burned magnesia or electrofused magnesia as the raw material and bured under the condition of ultra high temperature.
