所谓低碱度渣还原工艺就是用2:1的石灰与粘土砖(废汤道砖)造低碱度渣快速还原的工艺,它是由五厂二车间通过不断改革Al_2O_3—CaO合成渣洗法演变而成的。为了变革传统的白渣法冶炼工艺,早在六十年代,五厂二车间就采用渣洗GCr_(15)后的废Al_2O_3—CaO合成渣,通称返回渣渣洗20～65~#等优质碳素结构钢,其工艺要点为炉内扒去氧化渣后加入返回渣、Fe—Mn、Fe—Si和插入铝块,随即出钢,同炉渣钢混冲,缩短电炉还原期。后由于物资供应问题,GCr_(15)恢复白渣法冶炼,优质碳素结构钢相应改为,石灰—高铝炉 The so-called low alkalinity slag reduction process is to use 2: 1 lime and clay bricks (waste soup brick) to create low alkalinity slag rapid reduction process, which is the second plant by five plants through continuous reforming Al_2O_3-CaO synthetic slag washing Evolved In order to change the traditional white-residue method smelting process, as early as the sixties, Wuchang No.2 workshop adopted slag-washing GCr_ (15) after the waste Al_2O_3-CaO synthetic slag, known as the return of slag washing 20 ~ 65 ~ # and other quality carbon The structure of steel, the process points for the furnace to remove the oxide residue after adding back slag, Fe-Mn, Fe-Si and insert the aluminum block, then tapping, mixed with the slag steel red, shorten the reduction period. After due to material supply, GCr_ (15) recovery of white residue smelting, high-quality carbon structural steel accordingly, lime - high-aluminum furnace
