METHOD FOR PRODUCING BUILDING MATERIALS FROM METALLURGICAL SLAG Russian patent published in 1995 - IPC

FIELD: building materials production. SUBSTANCE: method for producing building materials from metallurgical slag includes introducing diluent and silicon bearing addition into slag melt, mixing slag melt and subsequent cooling. The diluent could be introduced in slag melt jet when discharging in scoop or fairly in empty scoop, and then slag melt is discharged into the scoop. The diluent may be introduced either in empty scoop or in melt slag jet when feeding slag in the scoop. The diluent may be introduced in melt slag jet when discharging from the scoop into the basin. The diluent may be introduced into empty slag basin, and then slag melt is fed into the basin. The diluent may be introduced either in empty slag basin or in slag melt jet when discharging from the scoop into the slag basin. The diluent may be introduced in a mixer either before dumping slag melt in it, or in melt slag jet when dumping slag in the mixer, or in empty mixer and in melt slag jet when dumping it in the mixer. EFFECT: not expensive materials. 10 cl
