COAGULATION SLAG PRODUCTION APPARATUS, PRODUCTION APPARATUS OF COARSE AGGREGATE FOR CONCRETE, COAGULATION SLAG PRODUCTION METHOD, AND PRODUCTION METHOD OF COARSE AGGREGATE FOR CONCRETE
Document Type and Number:
Japanese Patent JP2014131950
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a coagulation slag production apparatus that can produce a coagulation slag in which breaking efficiency and a yield are excellent; a production apparatus of a coarse aggregate for concrete; a coagulation slag production method using the coagulation slag production apparatus; and a production method of a concrete coarse aggregate using the production apparatus of a coarse aggregate for concrete.SOLUTION: A coagulation slag production apparatus 1 is the coagulation slag production apparatus that includes two or more metallic casting molds 5 that have an excavation part 5a in which a molten slag is made to flow, and produces a coagulation slag by flowing the molten slag in the excavation part 5a, and is characterized in that a convexity bar part 5d having at least 5 mm of a height for forming a groove part 18a in the coagulation slag 18 on a back surface of the casting mold 5.
