Uhlalutyo lwezizathu zeengozi kwindawo yebhloko yokungena kwamanzi e-ladle

Umsebenzi webhlokhi ye-ladle nozzle kukukhusela i-vent core. Ukuba iqhekezwe ngokungaqhelekanga ngexesha lokusetyenziswa, ayiyi kuphumelela kuphela ukuyikhusela, kodwa iingozi zingenzeka phantsi kweemeko ezinzima. Esona sizathu siphambili sokuqhekeka kwibhloko ye-ladle nozzle kukuba ukongeza kumgangatho ongafanelekanga webhloko ngokwayo, izinto ezahlukeneyo kwindawo yokusetyenziswa komenzi wentsimbi nazo ziya kuchaphazela uzinzo lwebhloko ye-ladle nozzle.

Uyilo olungenangqiqo lwebhloko ye-nozzle ye-ladle lubonakaliswa ngokukodwa kwizibonakaliso ezibonakalayo kunye neekhemikhali. Umlinganiselo wezinto ezingenangqiqo wenza ukuba ukuxhathisa ukutshitshiswa kwe-thermal kuphantsi kakhulu, ukuqhekeka kunye nokuphuka ngexesha lokusetyenziswa, okubangelwa ukugqabhuka. Ukusombulula enye yeengxaki, kuyimfuneko ukulungelelanisa umlinganiselo wezinto eziphathekayo zebhloko ye-nozzle kwi-ladle ukuphucula ukusebenza kokutshatyalaliswa kwe-thermal; ukongeza, ukunyuka okufanelekileyo kwefiber yensimbi kunokuphucula amandla ebhloko ukuya kumlinganiselo othile kunye nokuphucula ukuzinza.

Umfanekiso 1 Ibloko yomlomo weLadle

Kuyo yonke imveliso enkulu yasekhaya yentsimbi, xa ufaka izitena eziphefumlayo, uninzi lwezitena lufakwe ngokuthe ngqo kwigobolondo yensimbi, kwaye abambalwa baya kubeka uluhlu lwezinto eziphathekayo kwi-shell shell. I-Ke Chuangxin Material icebisa ukusebenza kokugqibela. Oku kungenxa yokuba intsimbi Iqokobhe linokukhubazeka kwaye lingalingani ngenxa yezinto ezifana nobushushu obuphezulu, impembelelo yokuphakamisa, impembelelo yokukhupha kunye nezinye izinto emva kokusetyenziswa kwexesha elide. Emva kokuba kufakwe isitena somoya, i-bottom ye-ladle nozzle block kunye ne-shell shell point phantsi kwe-ladle ayikwazi ukudibanisa ngokusondeleyo. , Kuya kubakho izikhewu ezingaphezulu okanye ezincinci, ezinokukhokelela ekuqhekekeni phantsi kwesiseko sezitena eziphefumulayo, kunye nokuvuza kwentsimbi. Ukusuka kumbono womatshini, umzantsi ongalinganiyo wesitena sesihlalo ulingana nokongeza i-fulcrum kuyo. Ngaphantsi kwesenzo soxinzelelo lwe-hydrostatic kunye nokutshatyalaliswa kwe-thermal yensimbi, isitena sokuhlala sixhomekeke ekuqhekekeni. Ngoko ke, xa ubeka ibhloko yezitena ezinokungena emoyeni, sincoma ukugudisa iqokobhe lentsimbi nge-chromium corundum enokulahlwa kwaye ubuyisele ipleyiti yokuxhasa eyonakele kakhulu ngexesha.

Ukuze kube lula ukufakwa kunye nokususwa kwezitena zesiseko se-ladle nozzle, abavelisi be-steelmaking ngokubanzi bagcina i-gap ye-40-100mm phakathi kwezitena zesiseko kunye nezitena ezisezantsi ze-ladle, kwaye ekugqibeleni zizalise nge-castables. Sincoma ukuba i-castable ifanele ibe yi-corundum enomgangatho ophezulu kunye neyona nto iphezulu, enenzuzo yobuninzi be-fluidity kunye nokumelana nokubola. Umgangatho we-joint filler uhluphekile, kwaye uya kudliwa ngokukhawuleza emva kokutshatyalaliswa yintsimbi etyhidiweyo, okubangelwa ukuvezwa kunye nokuqhekeka kwesiseko sezitena esiphefumulayo, esichaphazela ukusetyenziswa kwezitena eziphefumulayo.

Umzobo 2 ipleyiti ephantsi yeqokobhe lentsimbi

Namhlanje, ngophuhliso olukhawulezayo lwetekhnoloji yokunyibilikisa isinyithi, inkqubo yokucoca ngaphandle kwesithando somlilo ibe yinxalenye ebalulekileyo yenkqubo yokunyibilikisa intsimbi, kwaye ukusetyenziswa ngokuchanekileyo kwezitena eziphefumulayo kuhambelana ngokusondeleyo nokhuseleko lwemveliso.
