Methods for increasing the quality of medium-grain structural graphites
Source abstract
Abstract
Different methods are considered for improving the quality of large-sized medium-grain graphites. Among these methods as very effective it is possible to separate assembly of a needle in the central part of the die making it possible to compact billets with a central hole that markedly reduces internal stresses in the material during heat treatment; use of oleic acid as a surfactant during mixing makes it possible to reduce the pitch content of the mix; elimination of the mixer method of cooling the coke-pitch mix before compaction that increases the temperature uniformity of the compacted material.
