Itekhnoloji entsha yokunyibilikiswa kwe-non-oxidation kwi-ZGMnl3 i-alkaline induction yokunyibilikisa iziko

(1) Ixesha lokunyibilika kweziko lokunyibilikisa induction

Umbane uyanyibilika. Ukubonelela nge-60% yamandla ngaphakathi kwe-6-8min emva kokuqala ukunika amandla, kwaye ngokuthe ngcembe ukwandisa amandla ukuya phezulu emva kokuyeka impembelelo yangoku. Ramming flux. Njengoko intlawulo kwindawo esezantsi ye-crucible inyibilika, nikela ingqalelo kwi-ramming nangaliphi na ixesha ukukhusela “ibhuloho”, kwaye uqhubeke ukongeza intlawulo. Ukuslagging. Emva kokuba ininzi yentlawulo iyancibilika, yongeza izinto ze-slagging (i-lime powder: i-fluorite powder = 2: -1), kwaye ugubungele intsimbi etyhidiweyo ngezinto ze-slagging. Ubungakanani bezinto ze-slagging ezongeziweyo yi-1% ~ 1.5%. Isampuli kunye ne-slagging. Xa intlawulo i-95% inyibilikile, thatha isampuli ukuhlalutya, kwaye ungeze yonke intlawulo kwisithando somlilo. Emva kokuba intlawulo iyancibilika, nciphisa amandla kwi-40% ~ 50%, ulahle i-slag kwisithando somlilo, wenze i-slag entsha.

(2) Ixesha lokunciphisa isithando sokunyibilikisa i-induction

ukukhutshwa kwe-deoxidation. Emva kokuba i-slag iyancibilika, yongeza i-deoxidizer (i-lime powder: i-aluminium powder = 1: 2) kwindawo ye-slag yokusabalalisa kunye ne-deoxidation. Ngethuba lenkqubo ye-deoxidation, i-lime powder kunye ne-fluorite powder ingasetyenziselwa ukulungelelanisa i-viscosity ye-slag ukuze i-slag ibe ne-fluidity enhle. Lungisa izithako. Lungisa ukubunjwa kweekhemikhali zensimbi etyhidiweyo ngokweziphumo zokuhlalutya, kwaye umxholo weSi kufuneka ulungiswe ngaphakathi kwemizuzu emi-5-10 ngaphambi kokubetha.

Ukulinganisa ubushushu kwaye wenze iisampuli zekomityi engqukuva. Ukulinganisa ubushushu bentsimbi etyhidiweyo kwaye wenze isampulu yekomityi engqukuva ukujonga i-deoxidation yentsimbi etyhidiweyo (okanye usebenzise indlela ye-engile yokugoba ukugweba).

Faka i-calcium silicate. Emva kokuba ubushushu bensimbi etyhidiweyo bufikelele kwi-15OO ° C okanye ngaphezulu (umlinganiselo wokushisa), i-0.2% ye-calcium silicate ifakwe ukuqhubela phambili i-deoxidize, kwaye i-deoxidizer yongezwa kwi-slag surface kwakhona. Faka i-aluminium, emva kokuba ubushushu bensimbi bufikelele kwi-1500 ° C okanye ngaphezulu, susa yonke i-slag, uze ungeze i-0.07% ye-cryolite powder (okanye i-agent egubungela i-slagging) kwaye ufake i-aluminium.

(3) Ukucofa intsimbi nokugalela

Intsimbi ngaphandle. Emva kokufaka i-aluminiyam, shukumisa intsimbi etyhidiweyo kwaye ucofe intsimbi emva kokuphela kombane. Emva kokucofa, thatha iisampulu kwi-ladle yohlalutyo lwemichiza yentsimbi etyhidiweyo egqityiweyo. ukugalela. Emva kokucofa, yongeza uthuthu lwengca ukugubungela umphezulu wentsimbi etyhidiweyo ukukhusela intsimbi etyhidiweyo kwi-oxidizing. Emva kokuba intsimbi etyhidiweyo ibulawe imizuzu emi-3-5, iqondo lokushisa kwi-ladle li-1460-1480 ° C, kunye nokushisa okuthululwayo ngu-1340-1380 ° C, okanye ngaphantsi okanye ngaphezulu, kuxhomekeke kwiimfuno zokuphosa.
