PRODUCTION OF SLAG FOR ROCK WOOL AND PRODUCTION OF ROCK WOOL

摘要

PROBLEM TO BE SOLVED: To produce rock wool having an optimum wool diameter in high yield. ;SOLUTION: The producing method includes a process for forming molten slag in which molten metal is dispersed by melting incineration ash in a reducing atmosphere to reduce iron portion in the incineration ash to metal iron and a process for settling the molten metal in the molten slag by keeping the formed molten slag in a melted state for ≥2 hr.;COPYRIGHT: (C)2000,JPO
