电熔镁铝尖晶石

电熔镁铝尖晶石
电熔镁铝尖晶石是以纯度≥98.5%的工业氧化铝和纯度≥96%的轻烧镁并配入适量的高纯菱镁矿(MgO>47%)做配合料,在电弧内经高温熔制合成的耐火原料,其晶粒发育良好,质地致密,结构均匀,是制造高强度,热震稳定性好的尖晶石--方镁石高级耐火制品的一种高档原料。 电熔镁铝尖晶石是制造连铸滑板、水口砖、钢包衬砖的理想原料,也是大型水泥回转窑过度带衬砖、耐火浇注料及高、中温窑具用的基本原料,镁铝尖晶石制品的高温力学性能稳定。

 

Fused Magnesia--Alumina Spinel
The electro fused magnesia-alumina spinel is a synthetic refractory mateeral from commercial alumina (purity over 98.5%),Light fired magnesia(purity over 96%)and sone high purity magnesite (MgO over 47%)by high tempera-ture melting in electricalo arc fumace. the fusedMg-Al spinel consists of well grown crystals and possesses high density and structure honmogenelty.So it is a high quality raw material gor manufacturing spinel-periclase refractories withhigh sttength and good thermal shock resistance .The fused Mg-Al spinel is ideal raw material for the production of continuous casting,Slide gete bricks for casting mozzle,firebricks for lining of ladle,liner bricks for cement kiln,refractory casting,Kiln furniture for mediu and  high temperature applications.
