Product Description

Fused Magnesite Brick 98% Sintered

Magnesia Bricks was prepared with hercynite as raw materials. The application results showed that the kiln coating formed rapidly and stability when using magnesia-hercynite brick. The magnesia-hercynite brick had low thermal conductivity and long service life, and its overall performance was better than magnesia-chrome brick.

Material and Technique: fused magnesia, shaped under high pressure, fired under ultra high temperature and finished with post technical treatment. Property: high bulk density, good high-temperature performance and strong hydration resistance. Application: used in the tapping hole of the convertor with severe slag corrosion and wear, the slag line of non-ferrous furnaces, the tapping hole of metal mixer furnaces, and chimney block of glass tank regenerator.

Refractory Magnesia Bricks

1.High refractoriness,usually the refractoriness is above 2000°C.
2.Refractoriness under load about 1500-1550°C because of poor high-temperature intensity.
3.Strong ability to resist basic (alkaline) slag,can not contact with acid refractory material.
4.Poor Thermal shock resistance,so keep the temperature of furnace stabilized.
5.Poor Volume stability at high temperature,must set aside appropriate expansion joint when laying brick.
6.Strong ability of thermal conductivity,sometime need insulating material.
7.Hydrability, keep product away from moisture during storage.
