Magnesium-calcium brick/Used for used in stainless steel converter, smelting, AOD,VOD/Alkaline slag resistance
Product description:
Dolomitic sand, magnesia dolomitic sand and magnesia are used as
raw materials, mixed with anhydrous binder, high-pressure forming
and fired at high temperature.
Category of Refractory Brick/Fire Brick:
magnesium-calcium brick/Magnesium-dolomite brick
Magnesia dolomite brick and magnesia calcium brick main composition
are MgO and CaO, just have a few distinction, magnesia calcium
brick that magnesia dolomite brick is MgO content is tall, exceeded
the magnesia calcium ratio of dolomite brick kind, dolomite brick
is the brick that the magnesia calcium ratio in normal dolomite
(1:1), main chemical composition is MgO and CaO are collectively
referred to as magnesia calcium brick.
Features:
Magnesia dolomite brick is more stable than magnesia brick and
magnesia chrome brick under vacuum, it has good high temperature
performance, strong corrosion resistance, high softening
temperature under load (above 1700℃), and has the function of
purifying molten steel.Mainly used in stainless steel converter,
smelting, AOD,VOD.
