| The technological innovations in iron and steel making processes
and development of superior quality refractories have reduced
specific refractory consumption significantly. More than 70% of
refractory consumption in Japanese iron and steel works is in
torpedo ladle cars, converters, electric arc furnaces, ladles and
continuous casters.
This paper highlights the current status of technological
development of the refractories, viz. AI20,-C, AI20,-SiC-C,
MgO-C, spinel castahles and other refractories used for BOF,
electric arc furnaces and ladle furnaces. It also covers the
design aspects of refractories used in various furnaces/vessels
which ultimately result in higher quality, more safety and lower
cost of steel production. |
