Ukuqhekeka okuphambene kuzothinta izinga lomkhiqizo oqediwe ngemva nje kokugingqika.Khulisa isikhathi sokuhlanza i-billet, kokubili ukulimala okukhulu.Izinga lokushisa le-slab liyi-brittle zone engu-700-900 ℃.Isizathu sokuqhekeka kwendawo ephansi ngu-1050-1100 ℃, imifantu ephambanayo ebusweni besizathu ingaphezulu le-billet ngengxenye enkulu yokuqondisa ingcindezi yokuqondisa.I-Niobium nitride emingceleni yokusanhlamvu ye-austenite inciphisa amandla okubopha, imvula yomngcele wokusanhlamvu.Kuleli qophelo engxenyeni egobile ye-slab junction i-arc impofu, okuholela ekuqhekekeni kwendawo ephansi.Imifantu eqondile kanye nokwakheka kwamakhemikhali, izinga lokushisa kwamanzi okupholisa isikhunta, okokusebenza kwesikhunta, ukwakheka kwamakhemikhali e-slag, umshini wokuphonsa oqhubekayo wokunemba wesistimu yokupholisa yesibili ehlobene.Izinyathelo zokuvimbela ezihlobene:
1. Lawula ukwakheka kwensimbi.Zama ukuvimbela i-wC ingu-0.12% -0.16% okuqukethwe kwekhabhoni yensimbi engu-D36 endleleni yokulawula inqubo yokuncibilika ngokomkhawulo ongaphezulu.Inganciphisa ngempumelelo imifantu.Indawo yokusabela ye-Peritectic.
2. Control crystallization lokushisa lokushisa njalo isikhunta, izinga lokushisa isikhunta kushintsha indlela ephumelelayo ukuthuthukisa iwukuba ukwandisa isikhunta ukupholisa idivayisi preheating amanzi.Ukucindezela ukwenzeka kwemifantu lapho isimo sezulu sishintsha.Ingasetshenziswa futhi emva zonke stop ukuthulula futhi ethela isikhathi ayivulwanga lapho izinga lokushisa kwamanzi ingaphansi 20 ℃ isikhunta isikhunta ukupholisa amanzi, ukuqinisekisa ukuthi izinga lokushisa ukubunjwa isikhunta fashion.
3. Lungisa imingcele yenqubo ye-crystallization ukuze ulungise inani lamanzi usayizi wesikhunta, ngokusho kogqinsi lwethusi oluhlukene.Ngokulungisa inani lamanzi ukuqinisekisa ukuthi izigaba ezahlukene zokupholisa kwesikhunta esifanayo.
4. Ukuthuthukisa isistimu yokupholisa yesibili, ukuthuthukisa izinga lokushisa lendawo yokuqondisa, ngokuthuthukisa isistimu yokupholisa yesibili.Vimbela i-brittle zone billet straightening, kunganciphisa kangcono amathuba okuqhekeka kwe-slab transverse.
5. Ukuhlanzwa kwe-strand ngokubukeka kwe-strand nokususwa kwekhona le-slab scarfing, kuyindlela ephumelelayo yokuhlanza isiqinisekiso sekhwalithi sokugcina se-slab billet.Singakwazi ukuthuthukisa ikhwalithi yokugcina ye-slab.
