High Temperature Resistance Magnesia Brick For Nonferrous Metal Melting Furnace
Products technical:
1.The products are fused magnesia as main raw material, after a reasonable size distribution,
high pressure forming, high-temperature sintering. The product has strong resistance to slag
corrosion ability and high temperature dimensional stability. Mainly used in glass furnace
regenerator, the upper part.
2.The regular magnesia bricks are made from dense dead burned magnesia that makes the bricks
in good refractoriness, corrosion-resistance, and widely used in checker chamber of glass tank,
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.
They have the features of highly directly bonded and corrosion-resistance and widely used in various
kinds of high temperature kilns and furnaces
Magnesia Brick Features:
Excellent performance of basic slag resistance, high refractoriness, thermal stability, anti-erosion and anti-peeling
Excellent strength of pressure bending, abrasion proof
Excellent performance of high-temperature firing, high rates of associative property, anti-erosion ability
Excellent thermal shock resistance and spalling resistance
Excellent ability of high refractoriness, anti-erosion of alkaline residue;
High temperature load of refractoriness under load. High mechanical strength
High temperature resistance Excellent corrosion resistance
Resistance to spalling
Magnesia products:
Msgnesia brick,magnesia alumina brick,magnesite carbon brick, magnesia chrome brick and
magnesite-zircon brick ect are the main products of basic refractories,the products have
the properties of bearing high temperature,high refractoriness under load and good resistance o alkali.
they are widely used in the basic zone of metallurgical furnaces ,nonferous furnances and regenrator of glass furnaces.
