Magnesite brick
Magnesite brick description
Magnesite
brick is one of common basic refractories,Basia refractory materials
means the refractory brick major raw materials are basic oxide such as
MgO and CaO.Basic refractory bricks include magnesia brick, magnesite
silica brick, magensite chrome brick, magnesite alumina brick, dolomite
brick, forsterite brick and so on. From the characters of chemical, they
are all basic refractories, Strong resistance to erosion of basic slag.
so the basic steel & iron furnace/kiln, aways use this type
refractory bricks, at the same time, magnesite brick is widely used for
the Non-ferrous metal smelting industry, such as blast furnace for
producing copper,nickel, lead..., reverberatory furnace, converter.
Magnesite brick characters and application
Magnesite
brick is the major basic refractory brick, with the character of high
temperature of refractories,strong corrosion resistance for basic slag.
so magnesite brick widely used for metallurgical furnace,The firing
temperature of magnesia bricks is higher, reaching 1550-1650, and the
firing temperature of high purity magnesia bricks is as high as 1750 ℃
or even higher. Since the main matrix binding component of magnesite
brick is cms-m2s, magnesite brick softening temperature under load is
not high and its thermal shock resistance is not very good. The
properties of magnesia bricks are mainly determined by the properties of
raw materials, The mineral composition and microstructure formed in the
product.
Magnesite brick types
Magnesite
brick can be divided into sintered magnesite brick and non-sintered
magnesite bricks according to whether burned in the tunnel kiln.Non -
burnt magnesite brick is divided into chemically bonded magnesite brick
and asphalt bonded magnesite brick,sintered magnesite brick can be
divided into common magnesite brick, direct-rebonded magnesite brick,
semi-rebonded magnesite brick, fused rebonded magnesite brick.
