| Description |
An appraisal of raw materials for the blast-furnace --
THE blast-furnace operators at Jamshedpur face a pecu-
liar set of problems arising from the qualities of
the available raw materials. The basic problem is the
high alumina content of the blast-furnace slag ; attempts
to overcome it involve increases in coke and flux requirements with consequent loss of productivity. The
details can be analysed completely by a set of nomograms.
Turning to ore quality, a study of the varieties of ores reveals a wide divergence in reducibility. Moreover,
some of the ores are prone to disintegration during
handling and decrepitation by heating or exposure to
carbon monoxide. Details of test results show that the
quality of ores can be appraised only from a large number
of different tests. Similar tests are also required
for limestone. The quality of coke is best judged by
ash content as fluctuations in ash present the most
important problem.
