Magnesia Bricks
Magnesia refractory brick is alkaline refractory product that made
of high grade magnesia molding by high temperature, the main
crystalline phase is calcite, it is with properties of high
refractoriness, good anti-alkaline slag performance, high
refractoriness under load, but the thermal shock resistance is a
little week.
Magnesite refractory bricks are mainly used in steel-making alkaline open hearth furnace,
electric furnace bottom and furnace wall, converter permanent
layer, metal mixer working layer, non-ferrous metal smelting
furnace, high temperature tunnel kiln, cement rotary kiln lining,
glass furnace regenerative chamber checker brick etc.
Features of magnesia bricks:
1.Excellent performance of basic slag resistance. 2.High
refractoriness, thermal stability, anti-erosion and anti-peeling
3.Excellent strength of pressure bending, abrasion proof
4.Excellent performance of high-temperature firing, high rates of
associative property, anti-erosion ability
5.Excellent thermal shock resistance and spalling resistance
6.Excellent ability of high refractoriness, anti-erosion of
alkaline residue;
7.High temperature load of refractoriness under load. High
mechanical strength
8.High temperature resistance Excellent corrosion resistance
