Method for recovering residual matter accumulated in the production and machining of steel |
摘要 |
A method of recovering particulate matter having a high metal content and including dust resulting from production of steel and chips from machining of steel. The method includes selecting the chips that have a length of 7 to 30 mm; mixing the dust and the selected chips in the ratio of about 70:20 to 30:60 pts/pts; wetting the dust, before or after it has been mixed with the chips, to a moisture content of 3 to 8% by weight to hydrate free lime in the dust; and mixing the dust and selected metal chips with a suitable binder; and forming the mixture into briquettes.
