Apakah bahan mentah utama untuk meleburkan logam silikon?
Bahan mentah peleburan silikon:
Bahan mentah meleburkan logam silikon terutamanya termasuk silika dan ejen mengurangkan karbonaceous. Kerana sekatan ketat terhadap kandungan aluminium, kalsium dan besi dalam logam silikon, keperluan untuk bahan mentah sangat ketat. SiO2>99.0%, Al2O3<0.3%,><0.15%,><0.2%,><0.15%; the="" particle="" size="" is="" 15="" ~="" 80mm.="" the="" principle="" of="" choosing="" carbonaceous="" reducing="" agent="" is:="" high="" fixed="" carbon,="" low="" ash="" content,="" good="" chemical="" activity.="" usually="" petroleum="" coke="" or="" asphalt="" coke="" with="" low="" ash="" content="" is="" used="" as="" reducing="" agent.="" however,="" due="" to="" the="" two="" kinds="" of="" coke="" resistivity="" is="" small,="" poor="" reaction="" ability,="" so="" must="" be="" matched="" with="" low="" ash,="" high="" resistivity="" and="" strong="" reaction="" ability="" of="" charcoal="" (or="" wood)="" instead="" of="" part="" of="" the="" petroleum="" coke.="" in="" order="" to="" make="" the="" charge="" sintered,="" some="" low="" ash="" bituminous="" coal="" should="" be="" added.="" must="" point="" out,="" overmuch="" or="" all="" use="" charcoal,="" not="" only="" can="" raise="" product="" cost,="" and="" still="" can="" make="" furnace="" condition="" disorder,="" if="" because="" of="" material="" surface="" sintering="" is="" poor="" and="" cause="" prick="" fire="" to="" collapse="" material,="" form="" high="" temperature="" reaction="" area,="" bottom="" of="" furnace="" is="" easy="" to="" open="" into="" sic="" layer,="" give="" iron="" difficulty="">
