Product Details

Refractory ALUMINA-MAGNESIA SPINEL LADLE BRICKS kiln refractory brick


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 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

Features:

Magnesium aluminate spinel brick is a new product developed by our company according to the development current situation of building material industry and the performance characteristics of all kinds of lime kilns.

The product has the advantages of good alkali-resistance, good erosion resistance, good thermal stability, high crushing strength,and high refractoriness under load.
