Ubuchwepheshe obusha bokuncibilika okungeyona i-oxidation ku-ZGMnl3 isithando somlilo esincibilikisa i-alkaline

(1) Isikhathi sokuncibilika kwesithando somlilo sokungeniswa

Ugesi uyancibilika. Nikeza u-60% wamandla phakathi kwemizuzu engu-6-8 ngemva kokuqala ukunika amandla, futhi kancane kancane ukhuphule amandla abe phezulu ngemva kokuma komthelela wamanje. I-Ramming flux. Njengoba inkokhiso engxenyeni engezansi ye-crucible incibilika, qaphela ukugoqa nganoma yisiphi isikhathi ukuze uvimbele “ukufaka ibhuloho”, futhi uqhubeke nokwengeza inkokhelo. Slagging. Ngemuva kokuthi inkokhiso eminingi incibilikile, engeza impahla ye-slagging (i-lime powder: i-fluorite powder = 2: -1), bese uvala insimbi encibilikisiwe nge-slagging material. Inani lezinto ze-slagging ezingeziwe ngu-1% ~ 1.5%. Amasampula kanye slagging. Uma inkokhiso isincibilikile ngo-95%, thatha isampula ukuze lihlaziywe, bese wengeza enye inkokhiso esithandweni somlilo. Ngemuva kokuthi ukushaja kuncibilikile, nciphisa amandla ku-40% ~ 50%, ulahle i-slag esithandweni, wenze i-slag entsha.

(2) Isikhathi sokunciphisa sesithando somlilo sokuncibilika

i-deoxidation. Ngemuva kokuthi i-slag incibilikile, engeza i-deoxidizer (i-lime powder: i-aluminium powder = 1: 2) endaweni ye-slag ukuze isakaze futhi i-deoxidation. Phakathi nenqubo ye-deoxidation, i-lime powder kanye ne-fluorite powder ingasetshenziswa ukulungisa i-viscosity ye-slag ukuze i-slag ibe nomswakama omuhle. Lungisa izithako. Lungisa ukwakheka kwamakhemikhali ensimbi encibilikisiwe ngokuya ngemiphumela yokuhlaziya, futhi okuqukethwe kwe-Si kufanele kulungiswe kungakapheli imizuzu emi-5-10 ngaphambi kokuthepha.

Linganisa izinga lokushisa bese wenza amasampula enkomishi eyindilinga. Linganisa izinga lokushisa lensimbi encibilikisiwe futhi wenze isampula yenkomishi eyindilinga ukuze uhlole ukubola kwensimbi encibilikisiwe (noma sebenzisa indlela ye-engeli egobayo ukuze wahlulele).

Faka i-calcium silicate. Ngemuva kokuthi izinga lokushisa lensimbi encibilikisiwe lifinyelele ku-15OO ° C noma ngaphezulu (isilinganiso sokushisa), i-0.2% ye-calcium silicate ifakwa ukuze iqhubeke i-deoxidize, bese i-deoxidizer yengezwa endaweni ye-slag futhi. Faka i-aluminium, ngemva kokuba izinga lokushisa lensimbi lifinyelela ku-1500 ° C noma ngaphezulu, susa yonke i-slag, bese wengeza u-0.07% we-cryolite powder (noma i-ejenti yokumboza i-slagging) bese ufaka i-aluminium.

(3) Ukushaywa kwensimbi nokuthela

Insimbi ngaphandle. Ngemva kokufaka i-aluminium, gudluza insimbi encibilikisiwe bese ucindezela insimbi ngemva kokuphela kukagesi. Ngemva kokuthepha, thatha amasampula kuladi ukuze uhlaziye ukwakheka kwamakhemikhali ensimbi encibilikisiwe ephelile. ukuthela. Ngemva kokuthepha, engeza umlotha wotshani ukuze umboze ingaphezulu lensimbi encibilikisiwe ukuze uvimbele insimbi encibilikisiwe ekubeni i-oxidizing. Ngemuva kokuthi insimbi encibilikisiwe ibulewe imizuzu engu-3-5, izinga lokushisa ku-ladle liyi-1460-1480 ° C, futhi izinga lokushisa lokuthulula liyi-1340-1380 ° C, noma liphansi noma ngaphezulu, kuye ngezidingo zokuphonsa.
