Abstract
A solidified product (B) is produced by charging a dust (11) generated in a steel making process and containing iron and an oxide thereof as a principal component into a mold (7) and by subjecting it to a pressure molding. A raw material charged to the mold is a mixed granulated product (11p) prepared by mixing the dust and a powder containing carbon as a principal component and by granulating the resultant mixture.
Claims11
A steelmaking dust solidified product comprising a dust containing, as a principal component, iron and its oxides, produced during a steelmaking, and molded under pressure within a mold with a raw material supplied thereinto, in which the raw material to be charged into the mold comprises globular granulated particles of the dust and a powdery material including carbon as a principal component, the raw material being mixed together and granulated.
A method of making a steelmaking dust solidified product, which comprises:
- supplying a dust containing, as a principal component, iron and its oxides, produced during a steelmaking, into a mold;
- molding under pressure and solidifying the dust within the mold assembly to solidify such dust to thereby provide the steelmaking dust solidified product;
- wherein as a raw material to be supplied into the mold, globular granulated particles of the dust and a powdery material including carbon as a principal component, which are mixed together and granulated, are employed.
