Product Overview

Description

Magnesium zirconium checker brick for glass furnace and regenerative chamber

Specifications

 Magnesia Zircon Brick

1. HIgh refractoriness 

2. Good alkali resistance 

3. Superior refractoriness under load 4. Long service life

Product description

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.

3:The bricks with MgO 92% 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

Applications

Magnesia brick is characterized by high refractoriness ,good alkali resistance and superior refractoriness under load, and it is mainly applied to the regenerators of glass kilns and other high tempeature furnaces.
