High Refractoriness Clinker Magnesia Chrome Brick Refractory Brick
Prices
High chrome bricks use corundum and fused by chromic oxide and
zirconium oxide as the main raw material, match with a variety of
oxide powder additives, through numerical control intelligent
hybrid configuration, molding, drying, in shuttle kiln high
temperature burn becomes. High chrome brick have features of good
thermal shock resistance, volume stability under high temperature,
alkali slags resistance, and high refractoriness under load. high
chrome refractory brick is mainly applied to line the sintering
zone of the new dry processing of cement kilns and glass tank
furnaces as checkers and the other industrial furnaces.
High Chrome Bricks Description
High chrome bricks is made of magnesia (MgO) and chromium oxide
(Cr2O3) as the main ingredient, periclase and spinel as the main
mineral components of refractory products. Such brick high
refractoriness, high temperature strength, resistance to basic slag
erosion resistance, excellent thermal stability, acidic slag also
has some adaptability. The main raw material to manufacture high
chrome refractory brick is sintered magnesia and chromite. Purity
magnesia raw material to be as high as possible, the requirements
of the chemical composition of chromite is: Cr2O3: 30 ~ 45%, CaO1.0
~ 1.5%.
Properties of High Chrome Bricks
.High strength,
.Corrosion resistance,
.Erosion resistance,
.Excellent slag resistance,
.Good thermal shock stability.
Composition of High Chrome Bricks
High chrome bricks are mainly consist of Cr2O3, monoclinic zirconia
and alumina powder. Therefore, the performance of high chromebricks
is closely related to the performance of these substances. High
chrome fire brick contains chromium hemitrioxide 30%, and high
chrome brick is featured with acid and alkali slags resistance, and
are mainly used in the isolation layer, and nonferrous smelting
furnaces, etc.
High Chrome Bricks Manufacturing Process
High chrome refractory brick is made out of high quality magnesite
and chrome ore fine charge mixture. According to different demands,
adjust the content of Cr2O3, The product thermal stability and high
temperature performance are satisfactory. High chrome bricks are
widely used in the cement kiln and nonferrous metallurgical furnace
etc.

Application of High Chrome Bricks
High chrome bricks can be used in the metallurgical industry,
architectural material industry, and other non ferrous smelting
furnace, etc. and also can be applied to line the sintering zone of
the new dry processing of cement kilns and glass tank furnaces as
checkers and the other industrial furnaces.
