Ukudakumba komphezulu we-slab eqhubekayo okanye i-billet

I-slab eqhubekayo okanye i-billet surface ibonisa imingxuma engaqhelekanga, ubukhulu becala imingxunya esecaleni, kunye nemingxuma emi nkqo.Ukuxinezeleka kunye nokunye kwi-austenitic stainless steel (uhlobo lwe-Cr18Ni9) kunye nentsimbi ephantsi kwekhabhoni (i-carbon 0.10 ukuya kwi-0.15%) yendawo ye-slab.Ukudakumba kulula ukuvelisa kwi-lateral surface yobubanzi be-slab okanye inxalenye ye-angle ebanzi kuyo nayiphi na indawo yobuso.Ukudakumba okukhulu kukuqhekeka, ukuqhekeka komphezulu wokungena okunzulu kwentsimbi ebonakala inenxeba, kunye nokugqabhuka kwakhona kolusu.Isizathu sokuba kuveliswe i-slab surface depressions kuninzi.Ekubeni amanqanaba okuqala okuqinisa iqokobhe eliqinisiweyo "elibandayo kakhulu" i-billet yendawo ye-contraction ye-billet yendawo ebangelwa ukukhula okukhulu, okungalinganiyo kuya kukhokelela ekubunjweni koxinzelelo lwezindlu ezimbi;Igobolondo lensimbi ye-billet yokunciphisa i-longitudinal kunye noxinzelelo lwe-static olubangelwa ukusebenzisana phakathi kwe-bend kwakhona xa iphosa ukuvelisa ukudakumba kwecala;Utshintsho lwe-Ling lwenzeka (jonga kwisikwere kunye nokwahluka kwedayimani) kwi-billet kufuphi ne-engile ye-obtuse kufuphi neendawo zokuphumla ze-longitudinal (i-grooves) kunye neziphelo ezinde zobubanzi be-slab umphezulu wemingxuma ekubunjeni obangelwa kukupholisa okungalinganiyo;isizukulwana recessed kwakhona ixhalabele ukubunjwa intsimbi, austenitic stainless steel kunye nentsimbi ephantsi carbon kukukhula iqokobhe lokungunda ngokungalingani lula ukuvelisa imingxuma;ukusebenza okuphezulu kwensimbi engenastainless ukwandiswa kwe-thermal kunye ne-thermal conductivity ephantsi ephantsi koxinzelelo;Mr. low Carbon yaqina ngoko nangoko emva utshintsho austenite ibe ukucutheka umthamo ferrite xa intsimbi enkulu le sethako utyekelo ukwenza imingxuma ubuninzi.Okwangoku, iziganeko zokudakumba nazo zichaphazeleka kwiimeko eziqhubekayo zokuphosa: Ukusebenza njengepowder engafanelekanga yokubumba, ukuguquguquka kwenqanaba langaphakathi lokubumba, utshintsho kwisantya sokuphosa kunye nezinye izinto.Ukolula i-roller encangathi encangathi umzimba wangaphandle wesinyithi, ovelisa ukuhanjiswa kwamaxesha athile kwemingxuma (i-indentations) kwizinto ezibangela umphezulu we-slab.

Izisombululo zezi: umngundo eludongeni practice "okucothayo okupholisa", ukunciphisa indawo engaphezulu kufutshane ngundo ubushushu flux ngamandla, ukukhula ezimile kunye neqokobhe eliqinisiweyo, zingasetyenziswa ukubunjwa eludongeni plating okanye ebizwa ngokuba "hot top ngundo" ukukhuthaza blank iqokobhe ukukhula ngokufanayo;ukuguquguquka kwenqanaba lokungunda kuncinci (ngaphantsi kwe-3mm), usebenzisa i-flux yokusebenza kakuhle, ukulungiswa kwe-viscosity ye-flux ngokuhambelana nesantya sokuphosa, ukuqinisekisa ukuzaliswa okufanayo;umaleko we-slag wobukhulu obufanelekileyo, ukuzinza kwefilimu ye-slag ngokufanelekileyo ngokufanelekileyo ukushisa okuphezulu kunye nesantya sokuphosa;ukusetyenziswa okusengqiqweni iijiyometri umlomo wombhobho kunye nobunzulu obufanelekileyo wofakelo, ukuphepha i-vortex engamanzi kunye nabanye baye babonakala bexhasa ukukhula kweqokobhe iyunifomu, kunye nokunikela ingqalelo ukucoca iirola zokuqondisa, zinokunqanda imingxuma zenziwe.
