Title:
METHOD FOR MOLDING OF RESERVE REDUCING ORE INTO MASS
Document Type and Number:
Japanese Patent JPH01116035
Kind Code:
A
Abstract:
PURPOSE: To reduce the using amt. of a binder and to permit the molding of the above ores into a mass at relatively low temp. in a good yield by kneading the charcoal material of powdery reserve reducing ores having specific metallizing ratio thereto and subjecting the same to pressure molding.
CONSTITUTION: The charcoal material such as coal and coke breeze is kneaded to the reserve reducing ore powder having 30W80% metallizing ratio at a high temp. About 3W15% binder such as soft pitch and asphalt is added thereto, is subjected to pressure molding at ≤300°C and is molded into mass. In this way, the molded material having high strength can be manufactured in high yield by using reduced amounts of binder.
