Abstract
The process technology of iron and steel making is undergoing rapid changes
throughout the world. Larger capacity blast furnaces and taller coke ovens are the order
of the day. Basic oxygen steelmaking processes are replacing the conventional method
of steel making in open hearth furnace. Vacuum degassing, continuous casting, slide
gate valves etc are also gaining popularity.
The service conditions required to be met by refractories in the modern iron and
steel making units are very much severe demanding improved quality of materials.
In India, some· of the existing steel plants are on the threshold of expansion and
a few mini steel plants are also being put up. All these units are expected to adopt some
of the latest techniques in iron and steel making requiring improved quality of refractories
which are not available in our country at present. The quality of refractories that would
be required in future are reviewed in this paper with a view to focusing on the possibilities
of manufacturing them indigenously.
