Summary
Spinel is
a rare mineral in nature, and it must be made by artificial
synthesis. According to a certain proportion of raw materials,
mixing pressing ball molding (to join the right amount of pulp).
The characteristics of electric furnace melting temperature, in the
smelting process, to maintain the redox state, avoid Fe2O3 FeO
oxidation, to prevent the emergence of elemental Fe, after natural
cooling of the hercynite sand. The uniform large crystal (*5%) with
no grain boundary was revealed under the microscope, which was
similar to that of the glassy state. After processing into the iron
aluminum spinel brick, mainly used in large-scale cement rotary
kiln, instead of the current cement kiln used chrome brick, no Cr6+
pollution. Extended lining service life (magnesia chrome brick
****2 months and hercynite brick ****8 months), greatly reducing
the consumption of refractory material and manpower, reduces the
production cost, the full realization of the cement kiln chrome
free production, solve the chromium pollution. Fe Al spinel
represents a new generation of high performance chrome free
refractories for cement rotary kiln.
The two
main methods for the synthesis of spinel are sintering and electric
melting. Most spinel material is made from high purity synthetic
alumina and chemical grade magnesium oxide, namely in shaft kiln
sintering and fused in arc furnace.
Al Mg
spinel is a kind of aluminum magnesium oxide, its main component is
alumina and Magnesium Oxide. Al Mg spinel has two kinds of natural
formation and artificial synthesis. Natural magnesia spinel rarely
found industrial applications of magnesium aluminum spinel are all
artificial synthesis, the two main methods of synthetic magnesia
alumina spinel is sintering and electric melting method. Most
spinel material is made from high purity synthetic alumina and
chemical grade magnesium oxide, namely in shaft kiln sintering and
fused in arc furnace.
Sintering
magnesium aluminum spinel with good erosion resistance, corrosion
resistance, anti stripping ability strong, good slag resistance,
strong abrasion resistance, good thermal stability, resistance to
high temperature. Fused spinel has the characteristics of high
temperature resistance, high density, low water absorption, low
thermal expansion coefficient, good thermal stability and strong
anti erosion ability.
Spinel application
Sintered
magnesia alumina spinel is used for cement rotary kiln, which not
only avoids chromium pollution, but also has good resistance to
spalling. Sintered magnesia alumina spinel is used for making ladle
pouring material, which can greatly improve the anti erosion
ability of steel sheet lining. The preparation of high quality
synthetic spinel provides a new raw material for the production of
amorphous and amorphous high purity refractory
materials.
Electric
melting magnesium aluminum spinel is manufacturing plate, nozzle
brick, open hearth brick material. The high temperature mechanical
properties of aluminum and magnesium spinel products are good,
which are the basic raw materials of the filter belt, refractory
casting material and high. Fused magnesia alumina spinel used in
iron and steel smelting and glass industry furnace.
