Magnesite Refractory Brick

Dead burned magnesia bricks description

1. High temperature performance and high-density
2. Easy to rapid sintering
3. Good thermal shock stability

Dead burned magnesia bricks application
The regenerative chamber for the ceramic frit kiln, sodium silicate and glass furnace
The furnace lining of iron and steel industry, such as ferroalloys furnace, metal mixer
The non-ferrous metallurgy industrial furnace lining, such as the furnace copper, lead, zinc, tin, etc
Calcining kiln, shaft kiln and tunnel kiln for refractory material industry
The lining for cement rotary kiln

Advantage of  MgO Brick

MgO brick, it is to point to magnesium stone as raw materials, the Israeli magnesium stone as the main crystal phase, MGO style content in 80% ~ 85% or more of the refractory brick. Its products are divided into two categories: Metallurgical magnesia and magnesia products. Magnesia brick is the main products of basic brick, high refractoriness, of alkaline slag and iron slag has good resistance, high refractory brick is a kind of important. Mainly used in open hearth, oxygen converter, electric furnace and non-ferrous metal smelting, etc.
