Study on Chemical Composition Prediction in Regeneration Process of Scrap Aluminum

在废杂铝重熔再生过程中,由于原料化学成分波动较大,加剧了成分含量预报与调控的难度。本文对铝合金化学成分的等级标准进行数字化表征,并确定了各质量等级的评价标准,便于检验铸件优质程度。针对废杂铝再生过程各工序的化学成分变化特点,制定了配料工艺调控、保温过程成分预报和精炼工序成分调控等优化方案。

In the process of remelting and recycling of scrap aluminum, because of the large fluctuation of the chemical composition of the raw materials, it is difficult to predict and control the content of the composition. The grade standard of the chemical composition of aluminum alloy was digitally characterized, and the evaluation standards of each quality grade were determined, which is easy to test the quality grade of castings. Aiming at the characteristics of chemical composition change of the each procedure in regeneration process of scrap aluminum, optimization schemes of the burdening process control, component prediction in heat preservation process and the composition regulation in refining procedure were constituted.
