一、杂铜鼓风炉熔炼过程及熔炼产品的特点杂铜鼓风炉熔炼的炉料组成是简单的,杂铜、熔剂(少许)及高量的焦炭,并以一层焦炭一层铜料层层加入炉内底焦层上。废杂铜从炉顶慢慢下降时,经受予热而至风口中心线上方1.6~1.8公尺处开始熔化,熔化了的铜水沿底焦往下滴,并不断吸收赤热的焦炭及炉气放出的热量。铜料熔化铜水下降的过程,也正是与其中蒸气压大的金属蒸发和铜分离的过程:Zn(合金液中)→Zn(蒸气↑)Pb(合金液中)→Pb(蒸气↑)
First, the copper melting furnace blast furnace smelting process and the characteristics of melting products mixed copper blast furnace smelting charge composition is simple, miscellaneous copper, flux (a little) and high amount of coke, and a layer of coke layer of copper added to the furnace layer The bottom of the focal layer. Scrap copper slowly descends from the top of the furnace, subject to heat and to the center of the tuyere 1.6 to 1.8 meters above the start of melting, molten copper water along the bottom coke down and continue to absorb red hot coke and furnace Gas released by the heat. The process of copper material melting copper water descending is also the process of metal evaporation and copper separation with large vapor pressure: Zn (alloy liquid) → Zn (vapor ↑) Pb (alloy liquid) → Pb (vapor ↑)
