一、前言国家收缩银根,基建投资压缩,在基建项目中停止使用铝合金门窗装饰,使废铝的回收利用受到了一定限制,废铝合金的价格从每吨13,000元一下子跌到8000元左右,利用废铝易拉罐转化为“6063”铝合金的生产也受到严重的影响,造成金属回收部门销售废铝困难。为此,开辟废铝在工业生产的应用是当务之急。一方面要扩大废铝在工业上的应用范围,另一方面要节省高纯铝资源,其他工业上相应的降低成本,取得一定的经济效益。本文就利用废铝易拉罐、废铝合金门窗切头料、边角料熔铸成炼钢脱氧用铝进行叙述。
I. INTRODUCTION China’s contraction in monetary policy and the compression of infrastructure investment have stopped the use of aluminum alloy windows and doors in infrastructure projects, limiting the recycling of scrap aluminum. The price of scrap aluminum alloy plummeted from RMB 13,000 per tonne to about RMB 8,000 , The use of waste aluminum cans into “6063” aluminum production has also been severely affected, resulting in sales of scrap metal recycling sector difficult. To this end, open up the application of aluminum scrap in industrial production is a top priority. On the one hand, it is necessary to expand the industrial application of scrap aluminum, on the other hand, to save high-purity aluminum resources and to reduce costs in other industries and achieve certain economic benefits. This article on the use of scrap aluminum cans, aluminum scrap doors and windows cut materials, scrap metal casting into aluminum deoxidation described.
