present invention discloses a process for the pelletization of graphite powder. The process essentially uses natural starch in a proportion in a range of 4-5% of graphite as binder to facilitate in pelletization. The affinage of the pellets so formed is in the range of 15-30% and thus helps in reducing the dust poll...
The present invention is related to making improved graphite nipple i.e. connecting pin used in graphite electrode column in arc furnaces. Graphite nipple is a crucial component of electrode column and has to meet very stringent specifications. Along with other properties, performance of nipple is mainly governed by...
Phenolic resin spheres are obtained by adding 2-4 times of water by weight of phenolic resin, 0.5 to 5 % of polyvinyl alcohol (PVA) by weight of phenolic resin, 0.5 to 7 % of hexamethylenetetramine (HMTA) by weight of phenolic resin to the reaction vessel and stirring the mixture at suitable tanperature. Thus obtain...
