Alumina-magnesia-graphite materials are based upon a combination of fu
sed alumina or bauxite with magnesia (AMG + BMG). They are resin bonde
d with 10 % carbon in form of natural lamellar high purity graphite. T
hey also possess the advantageous property of progressive expansion du
ring heat treatment, over and above the reversible PLC behaviour. Stee
l ladle and torpedo ladle applications are examined in detail and the
new products are compared with those currently used in regular use.
