Iindlela zokuphucula ukusebenza kwegesi evuthela ezantsi kweleyidi

DW series ukuqhekeza uhlobo isitena esiphefumlayo

Siye sahlalutya inkqubo ye-argon evuthela phantsi kwe-ladle kunye neemfuno zezitena eziphefumulayo. Eli nqaku ligxininisa kwiindlela zokuphucula ukusebenza kwegesi evuthela ezantsi kweleyile.

1. Khetha umgangatho ongcono izitena eziphefumlayo

Ukuxhatshazwa kwe-corrosion kunye nokumelana nokukhukuliseka kwezitena eziphefumulayo azinakwahlulwa kwisiphumo senkqubo yokuvuthela ezantsi. Kuye kwafundwa ngokusebenza ukuba emva kokusetyenziswa kwexesha elide, izitena zendabuko ze-slit-type-permeable air ziya kuvalwa ngokungena kwensimbi ye-slit kunye nokwakhiwa kwe-slag kwizitena ezinomoya. Ngeli xesha, inqanaba lokuvulwa kwesitena esinokungena emoyeni kunye nenqanaba lokudlula emazantsi elile kunzima ngokwendalo ukuhlangabezana neemfuno zelitha yentsimbi.

Ukukhetha izitena ezinokungena emoyeni kunye nokumelana nokutshatyalaliswa kwe-thermal ephezulu, ukunyanzeliswa kwe-permeability kunye nokumelana nokukhukuliseka linyathelo lokuqala lokuphucula umphumo ophantsi wokuvuthela kwe-ladle.

Ububanzi be-slit, i-geometry ye-slit, kunye nokumanzi kwe-ventilating core material kwintsimbi etyhidiweyo kuchaphazela ukunyanzeliswa kwezitena zokungenisa umoya. Ke ngoko, xa ubomi obude bufuneka, isitena sokungenisa umoya esingenamoya sibe lukhetho olungcono.

2. Misela iiparameters zenkqubo yoxinzelelo lwerhasi efanelekileyo ephantsi

Ngokwedatha, ubuncinci obuphantsi obuvuthela uxinzelelo lwerhasi bulingana nesixa soxinzelelo lwerhasi kumphezulu wolwelo, ilahleko yoxinzelelo lombhobho wonikezelo lwerhasi, uxinzelelo olongezelelweyo olwenziwa ngamaqamza, kunye noxinzelelo olumileyo lwentsimbi etyhidiweyo kunye umaleko we-slag.

Ukuba uxinzelelo lwegesi ephantsi lincinci kakhulu, amaqamza aya kuba nzima ukwenza okanye ukuvuselela kuya kuba buthathaka kakhulu.

Ukuba irhasi ephantsi yokuvuthela iphezulu kakhulu, oko kuya kubangela ukuhla kokudityaniswa kweqamu kunye nokusasazwa, ukuncipha kokusetyenziswa kwerhasi ephantsi ukuvuthela kunye nokushukuma okugqithisileyo kwentsimbi etyhidiweyo, eyenza ukuba intsimbi etyhidiweyo idibane kakhulu nomoya ojikeleze umhlaba. , okubangela ukuba i-oxidation yesibini edibeneyo yentsimbi etyhidiweyo kunye nokwehla okukhulu kweqondo lokushisa.

Umgangatho wamabakala esinyithi ahlukeneyo umisela iinkqubo ezahlukeneyo zentsimbi. Olona xinizelelo lufanelekileyo lokuvuthela ngasezantsi kuhlangabezana neemfuno zenkqubo yokwenza intsimbi yokuqina kokuphithizela kwerhasi, ukuze inqanaba lolwelo lwentsimbi liqengqeleke ngaphakathi kwinqanaba elifanelekileyo, kwaye ezibandakanyiweyo ziya kudada ukuya kuthi ga kumlinganiselo omkhulu. Kwangelo xesha, inokudlala indima ye-ladle yokugubungela, ukuqinisekisa ngcono ukuba iarhente yokugubungela ifunxa ukufakwa okuqhutywa yimibhobho yomoya, kunye nokuphucula ubunyulu bentsimbi etyhidiweyo. Ukwenzela ukumisela ngokuchanekileyo eyona nkqubo ifanelekileyo yokuvuthela kwegesi iparameters zenkqubo yoxinzelelo, igeyiji yoxinzelelo kunye nemitha yokuqukuqela inokufakwa kumbhobho werhasi ovuthelayo osezantsi, kunye noxinzelelo lwerhasi ephantsi evuthelayo kunye nomthamo wonikezelo lwerhasi inokumiselwa ngokweladi eyahlukileyo. iiparamitha kunye neemfuno metallurgical.

ukuququmbela

Ukuphucula impembelelo yokuvuthela igesi ezantsi kwe-ladle, ukukhetha izitena eziphezulu eziphefumulayo ezinokumelana nokutshatyalaliswa kwe-thermal, ukumelana nokunyamezela kunye nokuxhathisa ukukhukuliseka kuyisinyathelo sokuqala. Ubudlelwane phakathi kokusetyenziswa kwenzululwazi kunye nezitena eziphefumulayo ezikumgangatho ophezulu zinokuchazwa njengokuncedisana
