ALUMNA-CARBON SLIDING SLATE

摘要

PROBLEM TO BE SOLVED: To provide a sliding plate that makes the embrittlement of alumina-carbon tissue hardly occur in an Al-killed steel casting and is excellent in economical efficiency.;SOLUTION: An alumna-carbon raw material contains a manganese component. A content of the manganese component is 0.3-8.0 weight% by outer percentage relative to the total amount of the alumna-carbon raw material and preferably 0.5-5.0 weight%. Both a burned product and an unburned product are possible, but the case of burning needs a burning temperature of 1400°C or less and preferably 1300°C or less. Even an Al-killed steel prevents the embrittlement of tissue.;COPYRIGHT: (C)2015,JPO&INPIT
