Method for Processing Aluminum Scraps as Melting Material for Reverberatory

摘要

(Problem) The present invention is directed to a method for treating aluminum scrap so that aluminum scrap can be directly reused in a reflex furnace without undergoing preliminary melting and refining by an induction furnace as a raw material of aluminum material, thereby producing a deoxidizer for steel. Applicable to;(Solution means) The present invention is to heat the aluminum scrap to 480 ~ 530 ℃ to decompose deposits, paints, accompanying organic materials, etc., and then to cool to 100 ℃ or less to crush with an impact crusher to separate the produced oxide Aluminum scrap for the reflection furnace, after removing more than 10 mm of pieces, the press forming body having a maximum weight of 7 kg, an apparent density of 2.4 to 2.65, and a ratio of the volume ÷ surface area of the molded body to at least 1.85 by means of a shoulder press machine. It is a processing method using a melting raw material.
