ALPHA STAR®
Description:
Alpha Star®
is a homogeneous calcined high alumina
aggregate. Specially selected high purity ores are custom processed and
calcined to obtain a dense, volume stable aggregate with low apparent
porosity. The combination of lower impurities and unique processing results
in a consistent high quality aggregate.
Applications:
Alpha Star®
is an ideal aggregate to resist abrasion and hot metal erosion in blast
furnace troughs and ladles. Its consistent physical and chemical properties
make it ideally suited for low cement castable applications.
