椰殼活性在冶金工業中的應用

由于椰(ye)殼(ke)活性(xing)炭(tan)具有還原性(xing)，所以在冶金(jin)(jin)工業可以用(yong)來還原礦石(shi)冶煉(lian)(lian)金(jin)(jin)屬(shu)。椰(ye)殼(ke)活性(xing)炭(tan)在有色金(jin)(jin)屬(shu)生(sheng)(sheng)(sheng)產(chan)中，椰(ye)殼(ke)活性(xing)炭(tan)常(chang)用(yong)作表面(mian)助(zhu)(zhu)熔(rong)(rong)劑(ji)，當有色金(jin)(jin)屬(shu)熔(rong)(rong)融(rong)(rong)(rong)時，表面(mian)助(zhu)(zhu)熔(rong)(rong)劑(ji)在熔(rong)(rong)融(rong)(rong)(rong)金(jin)(jin)屬(shu)表面(mian)形(xing)成保護(hu)層，使(shi)金(jin)(jin)屬(shu)與(yu)氣體介(jie)質分開，既可減(jian)少(shao)熔(rong)(rong)融(rong)(rong)(rong)金(jin)(jin)屬(shu)的(de)飛濺損(sun)失，又可降低熔(rong)(rong)融(rong)(rong)(rong)物(wu)中氣體的(de)飽和度。椰(ye)殼(ke)活性(xing)炭(tan)用(yong)途：椰(ye)殼(ke)活性(xing)炭(tan)冶金(jin)(jin)工業，以前椰(ye)殼(ke)活性(xing)炭(tan)就(jiu)用(yong)來冶煉(lian)(lian)鐵(tie)礦石(shi)，椰(ye)殼(ke)活性(xing)炭(tan)與(yu)焦炭(tan)熔(rong)(rong)煉(lian)(lian)的(de)生(sheng)(sheng)(sheng)鐵(tie)，即使(shi)化(hua)學組成相同，其結構與(yu)機械(xie)性(xing)質仍(reng)不相同。椰(ye)殼(ke)活性(xing)炭(tan)冶煉(lian)(lian)的(de)生(sheng)(sheng)(sheng)鐵(tie)一般(ban)具有細粒結構，鑄件緊密，沒有裂紋的(de)特點，用(yong)椰(ye)殼(ke)活性(xing)炭(tan)生(sheng)(sheng)(sheng)產(chan)的(de)生(sheng)(sheng)(sheng)鐵(tie)含雜質少(shao)，適于生(sheng)(sheng)(sheng)產(chan)優(you)質鋼。

大量椰(ye)殼活(huo)(huo)(huo)(huo)性炭(tan)還用于(yu)結晶(jing)硅生(sheng)產，生(sheng)產結晶(jing)硅用的(de)椰(ye)殼活(huo)(huo)(huo)(huo)性炭(tan)不應(ying)含(han)有(you)生(sheng)炭(tan)頭(tou)和過多(duo)的(de)灰分。椰(ye)殼活(huo)(huo)(huo)(huo)性炭(tan)還可以用于(yu)滲(shen)(shen)碳(tan)(tan)(tan)(tan)(tan)劑(ji)(ji)的(de)制造，凡是(shi)(shi)要(yao)(yao)求表面具(ju)有(you)較高的(de)硬(ying)度和耐磨性，而中心具(ju)有(you)良好韌(ren)性的(de)所有(you)鋼制品都要(yao)(yao)進行(xing)(xing)滲(shen)(shen)碳(tan)(tan)(tan)(tan)(tan)。用來對鋼制品進行(xing)(xing)滲(shen)(shen)碳(tan)(tan)(tan)(tan)(tan)作(zuo)用的(de)含(han)碳(tan)(tan)(tan)(tan)(tan)混合物稱為滲(shen)(shen)碳(tan)(tan)(tan)(tan)(tan)劑(ji)(ji)。單純椰(ye)殼活(huo)(huo)(huo)(huo)性炭(tan)的(de)滲(shen)(shen)碳(tan)(tan)(tan)(tan)(tan)效果較差。因此常用椰(ye)殼活(huo)(huo)(huo)(huo)性炭(tan)作(zuo)為原料，再加入(ru)一定(ding)數量的(de)接觸劑(ji)(ji)，制成滲(shen)(shen)碳(tan)(tan)(tan)(tan)(tan)劑(ji)(ji)。二(er)(er)硫化碳(tan)(tan)(tan)(tan)(tan)生(sheng)產，椰(ye)殼活(huo)(huo)(huo)(huo)性炭(tan)是(shi)(shi)制造二(er)(er)硫化碳(tan)(tan)(tan)(tan)(tan)的(de)最(zui)好原料，用來制造二(er)(er)硫化碳(tan)(tan)(tan)(tan)(tan)的(de)椰(ye)殼活(huo)(huo)(huo)(huo)性炭(tan)，應(ying)當是(shi)(shi)堅硬(ying)、容(rong)積重大、灰分和水分含(han)量小，固定(ding)碳(tan)(tan)(tan)(tan)(tan)含(han)量高。生(sheng)產1噸(dun)二(er)(er)硫化碳(tan)(tan)(tan)(tan)(tan)約需0.5噸(dun)的(de)椰(ye)殼活(huo)(huo)(huo)(huo)性炭(tan)。
