| Abstract |
| A comparative study of imported and indigenous nozzles has been made. The
laboratory tests indicated that over-all chemical compositions of the Indian nozzles
are comparable to those of foreign nozzles. Their textural characteristics are such that
Indian nozzles suffer very greatly from non uniformity. The study indicates that fireclay
compositions for nozzles need not be highly refractory. It is .. however, desirable
that alkalis be entirely avoided. The practice of using coarse grog particles of higher refractoriness
in less refractory bonding clay should also as far as possible be avoided.
The fabrication process must be such as to yield a dense product of uniform texture. |
