Iintanda ezinqamlezileyo ziya kuchaphazela izinga lemveliso egqityiweyo emva nje kokuqengqeleka.Ukwandisa ixesha lokucoca i-billet, zombini umonakalo omkhulu.Ubushushu be-slab yi-brittle zone ye-700-900 ℃.Isizathu sokuqhekeka komphezulu osezantsi yi-1050-1100 ℃, iintanda ezinqamlezileyo kumphezulu wesizathu ngumphezulu webillet ngecandelo elikhulu lokuqondisa uxinzelelo lokuqondisa.I-Niobium nitride kwimida yengqolowa ye-austenite inciphisa amandla okubopha, imvula yomda weenkozo.Kweli nqanaba kwicandelo eligobileyo le-slab junction i-arc ihlwempuzekileyo, ebangela ukuba kubekho iintanda ezisezantsi.Ukuqhekeka okuthe nkqo kunye nokwakheka kweekhemikhali, ubushushu bamanzi okupholisa ngundo, izixhobo zokubumba, ukwakheka kweekhemikhali ze-slag, umatshini oqhubekayo wokugalela uchanekileyo inkqubo yokupholisa yesibini enxulumene.Amanyathelo okuthintela anxulumeneyo:
1. Lawula ukubunjwa kwentsimbi.Zama ukuthintela i-wC yi-0.12% -0.16% i-D36 yensimbi ye-carbon content kwindlela yokulawula inkqubo yokunyibilikisa ngokomda ophezulu.Inokunciphisa ngokufanelekileyo iintanda.I-Peritectic reaction zone.
2. Control crystallization lobushushu ubushushu ngundo rhoqo, ubushushu ngundo utshintsho olusebenzayo indlela yokuphucula kukwandisa umngundo ukupholisa isixhobo preheating amanzi.Ukucinezela ukwenzeka kweentanda xa imozulu itshintsha.Inokusetyenziswa kwakhona emva zonke stop ukugalela kunye nexesha lokugalela ayivulwanga xa ubushushu bamanzi ngaphantsi 20 ℃ ngundo ukungunda ukupholisa amanzi, ukuqinisekisa ukuba ubushushu ukugalela fashion ngundo.
3. Lungisa iiparitha zenkqubo yecrystallization ukulungelelanisa ubungakanani bamanzi ubungakanani besikhunta, ngokuhambelana nobukhulu obuhlukeneyo bobhedu.Ngokulungelelanisa ubungakanani bamanzi ukuqinisekisa ukuba izigaba ezahlukeneyo zokupholisa ngundo efanayo.
4. Ukuphucula inkqubo yokupholisa yesibini, ukuphucula ubushushu bendawo yokuqondisa, ngokulungisa inkqubo yokupholisa yesibini.Thintela i-brittle zone billet straightening, kunokunciphisa ngcono ukubakho kweentanda ezinqamlezileyo ze-slab.
5. I-Strand ngokucoca imbonakalo ye-strand kunye nokususwa kwekona ye-slab scarfing, yindlela esebenzayo yokucoca i-slab billet yokuqinisekisa umgangatho wokugqibela.Sinokuphucula umgangatho wokugqibela we-slab.
