Technological improvement in the manufacturing of iron and
steel has significantly changed the functioning practice. Upsurge in the
capacity of heating system, the temperature on which it is operated, the
temperature through which it acts like hot metal plus the output relative to
inputs are shared to each and every unit. These radical changes along with the
need of improved practices for healthier industrialization and application
environment are demanding a new generation of refractory material with improved
properties, performance and life with eco-friendliness.
Magnesia carbon brick is a non-burning carbon composite
refractory material which is made of magnesium oxide and flake graphite as main
raw materials, various non-oxide additives and carbonaceous binder. Magnesiacarbon bricks are mainly used for the lining of converters and electric arc
furnaces, and slag lines of ladle furnaces.
As a composite refractory material, magnesia carbon brick
effectively utilizes the strong resistance to slag corrosion of magnesia and
the high thermal conductivity and low expansion of carbon, which compensates
for the biggest disadvantage of poor flaking resistance of magnesia.
1. A good struggle against high temperatures
2. A good resistance to oxidation after a scum is being
formed out of the molten metal
3. Good resistance to heat shock waves
4. It is so good at resistance to high temperature that it
prevents itself from being dysfunctional.
It is basic refractory which the main phase is periclase,
the source of magnesium. These merchandises have a good trait and
characteristics, such as high temperature resistance, Good slag resistance. durable deterioration confrontation
and stable measurements at very high temperatures.
The Main Trait which
everyone should be aware of: Application:
Magnesia Carbon brick is written off as by high
refractoriness, good alkali defiance and superior refractoriness under load,
and it is mainly applied to the devices in connections with the hot engines of
crystal furnaces and many kinds of high temperature blast furnaces.
