Abstract |
Investigations undertaken at the National Metallurgical Laboratory on forsterite
refractories have been reviewed. Relevant process details as developed on a
laboratory scale have been discussed. ·Pilot Plant studies on the production of
these refractories from basic rock, utilising two alternative processes, have been
described. The results indicate that it is possible to process serpentine to make
forsterite refractQries by a one stage process provided serpentine powders are
properly graded and blends of high packing densities are used. Magnesite additions
in such bodies, should preferably contain certain proportions of light calcined
magnesia. Fabrication pressure of the order of 10,000-14,000 p.s.i. appears to be
optimum for these mixes. The results confirm that on a large scale, the
two stage process developed earlier also yields good compacts of satisfactory
properties although the process is expensive both in initial capital outlay as well
as in process costs. |
