SA Great Wall Series Spinel Brick
|
| The
Refractory Materials are patent products owned
by our company, and take lead in performance both
at home and abroad. It is composed of crystal phase
and spinel, and characteristic of mass density,high
specific gravity,less blowhole porosity, high honding
strength, high hardness,high softening point under
load, good |
 |
| abrasion resistance, roding resistance
oxidation resistance, good thermal shock resistance
as well as strong corroding resistance for smelting
slag. They ar e widely used in various smelting
equipments. For top-blown, there ar Ausmelt furnaces,
Kaldo furnaces; for side-blown, Baiyin furnaces
Nolanda furnacs, convertrs; and for bottom-blown,SKS
oxygen botto-blown smelting furnaces, QSL bottom-blown
furnaces; in addition, there are also flash furnaces,
electric dilution furnaces, zinc-volatilizing rotary
kiln,and inside linings of cement rotary kilns
and glass kilns. Their lifespan has been one tims
longer than those of magnesium chromium, magnesium
aluminum and aluminum silicate. |
