Features of Magnesia Brick
Magnesia 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.
Typical Application of Magnesia Brick
Furnaces of metallurgy industry, heat treatment furnace.
Furnaces of chemical industry and construction industry.
Furnace of incineration of garbage, recirculating fluidized bed furnace .
