摘要

建立了废杂铝再生合金化工序的能效理论模型

研究了当调整不同种类合金元素含量时工艺参数对合金化能效的影响

并结合燃气消耗模型得出了不同合金化工艺的最小燃气供给量。结果表明

当调整某元素的相同含量时

补料操作比冲淡操作合金化能效更高

补料使用的中间合金中目标元素含量越高

则合金化工序能效越高

加入同质量的Si元素比任何其他元素的合金化能效都低。通过优化燃气供给方式

使合金化工序完成时熔体温度恰达到要求温度

此时合金化能效最高。

Abstract

The energy efficiency model of scrap aluminum regeneration during alloying process was established.The effects of processing parameters in condition of adjusting different kinds of alloying elements on alloying energy efficiency were analyzed.Combined with the gas consumption model

the minimum amount of gas volume supplied was presented in different alloying process.The results show that when the same content of an element is adjusted

the higher alloying energy efficiency is realized in feeding than that in dilution

and the higher the content of target alloying element in master alloys used in feeding is

the higher alloying energy efficiency is.The highest alloying energy efficiency can be observed with adding Si than any other elements.By optimizing way of gas supplied

when alloying process is completed

melt temperature just reaches the required temperature

where the highest alloying energy efficiency can be realized.
