Fused
magnesium aluminum spinel of RuiShi Brand is produced by mixing the
industrial alumina with the purity no less than *8.5% and the
caustic-burned magnesia with the purity no less than *6% and an
appropriate amount of high purity magnesite ,and smelting with high
temperature in the electric arcfurnaces ,and can be processed with
different size particle ,fine powder and superfine powder .its
grain is well developed with the features of compact texture and
uniform structure ,which is high-grade raw material for producing
high quality refractory products with high intensity ,good thermal
shock resistance .
Fused magnesium aluminum
spinel of ruishi brand has the characteristics of high temperature
resistance ,high density ,low water absorption ,low thermal
expansion coefficient ,good thermal stability ,and strong corrosion
resistance .it is ideal material to cast sliding plate ,nozzle
bricks ,ladle bricks and open hearth furnace bricks ,as well as the
basic material material for ecotone bricks of large cement kilns
,medium cement kilns ,refractory castable materials and first-class
and medium-class kiln furniture .and it is widely used in iron and
steel smelting ,cement rotary kiln and glass furnace .
