La description
Magnesia Bricks:
Magnesia bricks have passed ISO International Certificate.
1. Eroding resistant and peeling proof.
2. High temperature resistant.
Products technical features:
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 and high temperature dimensional stability. It is
mainly used in glass furnace regenerator.
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 of *5% or more take the secondary-burning dead
burned magnesia or electrofused magnesia as the raw material and
burned under the condition of ultra high temperature.
They have the features of high directly bonded and
corrosion-resistance and are 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.
Magnesia Products:
Magnesia brick, magnesia alumina brick, magnesite carbon brick,
magnesia chrome brick and magnesite-zircon brick, etc. are the main
products of basic refractories. The products have the properties of
bearing high temperature, high refractoriness under load and good
resistance to alkali.
They are widely used in the basic zone of metallurgical furnaces,
nonferrous furnaces and regenerator of glass furnaces.
