二、杂銅鼓风爐熔炼过程及熔炼产品的特点杂铜鼓风爐熔炼的爐料組成是簡单的,杂銅、熔剂(少許)及高量的焦炭,并以一层焦炭一层銅料层层加入爐內底焦层上。废杂銅从爐頂慢慢下降时,经受予热而至风口中心綫上方1.6～1.8公尺处开始熔化,熔化了的銅水沿底焦往下滴,并不断吸收赤热的焦炭及爐气放出的热量。銅料熔化銅水下降的过程,也正是与其中蒸气压大的金属蒸发和銅分离的过程: Zn(合金液中)→Zn(蒸气↑) Pb(合金液中)→Pb(蒸气↑)金属蒸气(主要是鋅其次是鉛)进入爐气,随后者逸出料面,并被氧化呈ZnO粉进入布袋收尘室中收集,
Second, miscellaneous copper blast furnace smelting process and characteristics of smelting products Miscellaneous copper blast furnace smelting charge composition is simple, miscellaneous copper, flux (a little) and a high amount of coke, and a layer of coke copper layer Add to the bottom of the furnace coke 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 therein: Zn (alloy liquid) → Zn (vapor ↑) Pb (alloy liquid) → Pb (vapor ↑) metal Steam (mainly zinc followed by lead) into the furnace gas, followed by escape from the surface, and was oxidized ZnO powder into the bag collection chamber to collect,
