Vaned stirrer for use in high temperature atmosphere

摘要

Disclosed herein is a heat resistant vaned stirrer for use in a high temperature atmosphere. To endure stirring operations in high temperature molten metals of 300 DEG -1200 DEG C., the stirrer vanes are formed of a carbon-ceramics composite material which is produced from coke powder blended with 10-50% by volume of ceramics powder and which has a bending strength higher than 200 kg/cm.
