<p>PURPOSE:To make metal scrap stuck thereon with cutting oil easily usable for a remelting process, by adding quicklime to said scrap and allowing the cutting oil to be adsorbed thereon. CONSTITUTION:The metallic scrap adsorbed thereon with cutting oil contains a large amt. of moisture and oily components and even if the same is recovered as scrap, the direct charging into a remelting furnace is prohibitive. Thereupon, about 1.6kg quicklime is added to about 2kg metallic scrap stuck thereon with the cutting oil and both are thoroughly mixed and is allowed to stand. The moisture and oil are absorbed in the quicklime upon lapse of about 24hr and the scrap is chargeable into the melting furnace. The quicklime of about <=10mm. diameter is preferably used.</p> |
