Iingxaki eziqhelekileyo ekusebenziseni izinto ezichasene neTundish, ezinye zazo ziingxaki zomgangatho wezinto ngokwazo, kwaye ezinye zazo zinxulumene nokwakhiwa kwendawo, zifuna ukujongwa ngononophelo kunye nohlalutyo. Ngoko ke ndilandele uze ufumane iingxaki kunye nezisombululo zolwakhiwo lweTundish oluchasene neTundish.
izinto ezomileyo / Izinto ezomileyo ezinamandla aphantsi
Emva kokungcangcazela nokubhaka, izinto ezomileyo azihlali zinamandla okanye zinamandla aphantsi, nto leyo eya kukhokelela ekuweni kwengxowa kwaye ichaphazele ukuveliswa kwetyala lokuphoswa okuqhubekayo. Emva kokuqwalasela nokuhlaziya ixesha elide, kugqitywe kwelokuba izizathu eziphambili zokungabi namandla okanye izinto ezomileyo zezi zilandelayo:
(1) iingxaki zokubhaka: isixhobo sokubhaka saseTundish esisetyenziswa kwisityalo sentsimbi sisixhobo sokugcada ngegesi, esiya kubangela itha eninzi kumbhobho okanye umonakalo kwisitshisi emva kokusetyenziswa ixesha elide, nto leyo ebangela ukuba isiphumo sokubhaka esibi sendawo kunye nokungabikho okanye ukungabi namandla aneleyo.
(2) ukungena okumanzi kwezinto ezomileyo: izinto ezomileyo zenziwe ngamasuntswana angama-70% kunye namasuntswana angama-30% empuphu ecolekileyo. Umpuphu ocolekileyo uqulethe isanti ye-magnesia kunye ne-ejenti yokubopha. Ngenxa yendawo ephezulu yomphezulu, umpu ocolekileyo ufunxa amanzi ngokulula kwaye umanzi.
Isisombululo: Okokuqala, kuyimfuneko ukuqinisekisa ukuba i-roaster iyasebenza xa itshiswa, ukucoca umbhobho wegesi rhoqo, ukususa i-tar kunye nothuli, kunye nokutshintsha izitshisi ezonakeleyo ngexesha elifanelekileyo; okwesibini, kuyimfuneko ukuqinisekisa ukuba izinto ezomileyo zomile kwaye zixutywe ngokulinganayo.
Iintshukumo Zokudada
Ngamanye amaxesha, i-turbulizer iya kudlula esihogweni phezu kwentsimbi engamanzi kwinkqubo yokwenziwa kwe-multi-furnace continuous casting, engakwaziyo ukuzinzisa ukuhamba kwentsimbi nokukhusela indawo echaphazelekileyo, nto leyo engalunganga kumgangatho nokhuseleko lwentsimbi engamanzi.
Isisombululo: Lungisa ifomula ye-turbulizer kwaye ulawule ukwandiswa phantsi kobushushu obuphezulu.
Intsimbi Eqhekekayo Nengena Kwimingxunya Yamanzi
Ukuqhekeka kwesiseko se-zirconium kwinkqubo yokuthulula kukhokelela ekuphumeni kwentsimbi, nto leyo edla ngokunyanzela ukuba ukuthungwa okuqhubekayo kuthintele imveliso okanye ukucima. Uhlalutyo lubonisa ukuba isizathu esiphambili sokuqhekeka kukunganyamezeli kakuhle kobushushu besiseko se-zirconium.
Isisombululo: Ubuninzi bomthamo we-zirconium core abunakuphakama kakhulu, kwaye ubuninzi bomthamo buphezulu, bube nzima ngakumbi ukumelana nobushushu.
Ukuqhekeka kweCase enkulu
I-casing enkulu iphakathi kwendawo yokungena kwamanzi ye-ladle kunye ne-tundish, kwaye umsebenzi wayo we-metallurgical kukuthintela intsimbi engamanzi ukuba ingatshizi kwaye i-oxidized ngexesha lokuhamba kwentsimbi engamanzi ukusuka kwi-ladle ukuya kwi-tundish. Eyona ngxaki ixhaphakileyo ekusebenzeni kwe-casing enkulu yephakheji kukuqhekeka ngenxa yokuqhekeka.
Isisombululo: Okokuqala, sebenzisa izixhobo ezine-thermal expansion coefficient encinci kunye ne-elastic mold ukuvelisa i-casing ukuphucula ukumelana noxinzelelo lobushushu. Okwesibini, xa i-casing kunye nombhobho wamanzi zingakwazi ukwabelana, amandla angaphandle awakwazi ukusetyenziswa kwinxalenye esezantsi ye-casing.
