METHOD OF UTILISING IRON, ZINC AND LEAD CONTAINING RECYCLABLE WASTES |
摘要 |
<p>Evaluating steel works dust containing iron, zinc and lead comprises mixing and/or agglomerating the dust with a finely ground carbon carrier that can react. The amount of carbon compared with all carbon-consuming reactions is present strongly sub-stoichiometrically in the charge and a further amount of finely ground carbon carriers is distributed between the agglomerates. Total amount of carbon is less than 80 % of the amount necessary for the carbon-consuming reactions in the charge at a rolling temperature of less than 1150 degrees C. Preferred Features: The carbon amount is measured so that the rolling slag contains no free carbon (1 %) even without oxidation.</p> |
