Product Description

1.Magnesia Brick Brief Description

Magnesia bricks are basic refractory bricks. Its magnesia content is from *2% to *7.7%, and cristobalite is as the main crystal phase.Magnesite bricks are generally divided into bonded magnesia refractory bricks and chemical combination magnesia bricks.Magnesia bricks have excellent performance of resistance to alkaline slag,so this kind firebricks are widely used in glass industry, cement industry,steel and iron industry,etc.

2.Magnesia Brick Catogeries
Magnesite bricks are generally divided into two types:

A） Sintered magnesite bricks

This kind of magnesia refractory bricks include direct combined magnesia bricks and recombined magnesia bricks, and fused magnesia bricks, which are made of natural magnesia sand and fired at the high temperature of ***0 to ***0 ℃, which will be used in high temperature requirement working environment,like the regenerator part of glass furnace. Fused magnesia bricks are taken fused magnesia sand as raw material and fired in the high tempreture tunnel klin. Some people have an incorrect idea the fused magensia bricks are made by casting method.

B) Unburned magnesite bricks

This kind of magnesia bricks include chemical bonded magnesia brick and asphalt bonded magnesite brick, which will be used in low temperature requirement working environment.Chemical bonded magnesia bricks are made with some chemical binders through being shaped and dried.

As a professional magnesia bricks manufacturer, Zhengzhou Shennan Refractroy Co.,ltd can produce different high-quality bonded magnesia refractory bricks according to the customers requirements.

3.Magnesia Bricks Applications:

a) In the glass furnace:

grids and heat exchangers of regenerators in the glass furnace, like magnesia checker bricks

b) In the iron and steel industry: steelmaking furnace linings, ferroalloy kilns, and iron mixing furnaces

c) In non-ferrous metallurgical industry furnaces, such as copper, lead, zinc, and side furnace linings;

d) In the building materials industry, such as magnesia bricks in lime kiln, magnesia spinel bricks in the cement rotary kiln.

e) In high-temperature calcining kilns, shaft kilns and tunnel kilns in the refractory manufacturing industry

4.Magnesia Bricks Advantages:

l High refractoriness
l Good alkali corrosion resistance and slag resistance
l High load softening starting temperature
l High purity Less pollution to glass liquid
l Long service life and high tempreture resistance
