METHOD FOR MELTING PROMPT INDUSTRIAL SCRAP, WEIGHT FOR MELTING, AND COMPRESSED LUMP FOR MELTING PROMPT INDUSTRIAL SCRAP

摘要

PURPOSE: To improve the reduction rate of aluminum, to simplify the process, and to shorten reduction treatment time. CONSTITUTION: In this method, the prompt industrial scrap of aluminum is melted by forming the prompt industrial scrap of aluminum into compressed lumps A and then melting them, and a molten metal 11 of molten aluminum is stored in a crucible 10. The compressed lumps A are put into the crucible 10 in which the molten metal 11 is stored, and these compressed lumps A are heated in the crucible 10. In the course of melting, a lid-like weight 14 is placed on a compressed mass A' to embed the compressed mass A' in a molten metal 13.
