Uhlalutyo olufutshane lweendlela zokunyusa izinga lokuvuthela i-ladle (2)

(Umfanekiso) Uluhlu lwe-GW lwe-slit uhlobo lwesitena esiphefumlayo

Isantya esisezantsi sokuvuthela kweleyidi sisiqinisekiso sokuveliswa okugudileyo. Isitena esinomoya obude obude sisiqinisekiso sokuvuthela okuphezulu. Ngokubhekiselele kwindlela yokuphucula isantya sokuvuthela i-ladle, siye sahlalutya kwimbono yokulungiswa kwezinto zezitena zokuphefumula umoya ophantsi, (jonga inxalenye yangaphambili ngeenkcukacha), kweli nqaku, sihlalutya kwimbono yokwandisa i-ladle. ubomi besitena sokungenisa umoya.

1. Sebenzisa kakuhle yonke into ukwandisa umsebenzi wezitena eziphefumulayo

Ukuhamba okukhulu kwerhasi ephantsi kuya kukhawulezisa ukhukuliseko lwezitena zokungenisa umoya eziphantsi. Ngoko ke, xa izitena zokungenisa umoya ezisezantsi zisetyenziselwa, kufuneka ukuba ulawule ngokungqongqo ukuhamba kwegesi kwizigaba ezahlukeneyo.

Ngoko ke, ngexesha lenkqubo yokucofa, umthombo wegesi kufuneka uvulelwe ukuvuthela ngasezantsi, ukwenzela ukuba intsimbi ebandayo ingene kumjelo womoya inyibilikiswe phantsi kokuntywiliselwa kwentsimbi enyibilikisiweyo yobushushu obuphezulu, ukwenzela ukuba kuthintelwe ukuvaleka okutsha komjelo womoya. ngenxa yobushushu obuphezulu kunye noxinzelelo lwe-static lwensimbi etyhidiweyo. Ukukhuthaza inkqubela phambili egudileyo yokuvuthela emazantsi;

Vuthela ngoxinzelelo oluphezulu, oko kukuthi, sebenzisa i-1.5-1.8 MPa igesi ephezulu yoxinzelelo ukuvuthela intsimbi edibeneyo kwi-slit ephuma kwi-passage yomoya ngaphakathi kwe-3-5 s (ngokuphindaphindiweyo amaxesha angama-2-3) xa uvuthela ezantsi. Izinga lokuvuthela kungenzeka kakhulu ukuba linyuke nge-2.5% -3%.

Ngethuba lokusetyenziswa, hlala uqaphela ukudibanisa kombhobho wegesi. Ukuba ukuvuza okudibeneyo, kufuneka kujongwe ngokukhawuleza ukukhusela uxinzelelo kumbhobho ukuba luncitshiswe ngenxa yokuvuza kwegesi kunye nokusilela kokuvuthela okuphantsi.

Rekhoda ubukhulu obushiyekileyo be isitena esinokungena emoyeni emva kokukhupha nayiphi na ixesha, ukwenzela ukuba isitena esinomoya ophantsi-ovuthuzayo sisetyenziswe kwinqanaba elikhulu kwaye ubomi balo benkonzo bunokwandiswa phantsi kwesiseko sokusetyenziswa ngokukhuselekileyo.

2. Ukugcinwa ngokufanelekileyo

Ngethuba lenkqubo yokuthululela, i-ladle ayikwazi ukubethelwa phantsi, ngoko ke inani elikhulu lokungena kwensimbi kwenzeka kweli nqanaba. Emva kokuthulula, iqondo lokushisa lomgca wangaphakathi we-ladle liyancipha ngokukhawuleza, kwaye isitena esinomoya ophantsi ophantsi-ovuthwe umoya siba yi-concave emva kokugqwala. Ukuze ugweme ukuqina ngokukhawuleza kwentsimbi eqokelelweyo, i-ladle kufuneka ilahlwe ngokukhawuleza kwaye umthombo wegesi ongenayo igesi efana ne-nitrogen okanye i-argon kufuneka ivulwe ngexesha elifanayo. Lawula uxinzelelo lomthombo womoya ngaphakathi koluhlu lwe-0.8-1. I-MPa ye-0 (ubuninzi beentsimbi zetsimbi), kwaye uvuthulule intsimbi engaqinisekanga kwi-air duct kunye nentsimbi eqokelelwe kwindawo edibeneyo yesitena esisezantsi esivuthela umoya. Umphumo wokucoca kunye nokugcinwa kwendlela yomoya yesitena sokungenisa umoya kunokukhuthaza ukusebenza kakuhle kwesibetho esilandelayo. Ukuya

Ngamanye amaxesha ngenxa yesingqisho semveliso kunye nezinye izizathu, ixesha lokulinda lide, okanye umgangatho osebenzayo wesitena ovuthela umoya ophantsi ugqunywe nge-slag yensimbi eseleyo, kwaye umphezulu kufuneka ucocwe. Sebenzisa ioksijini okanye umxube we-oksijini kunye negesi yamalahle ukutshisa i-slag yensimbi eseleyo phezu komhlaba, kwaye kwangaxeshanye uvule umthombo wegesi ukuba uvuthele umva, uvuthulule i-slag ye-steel seepage kwi-passage yomoya kunye neendawo ezihlaziyiweyo, kwaye kwakhona uphephe intsimbi eshiyekileyo kunye nentsalela ngexesha lokucoca Yavuthelwa kwindlela yomoya kwakhona. Olu hlobo lwamanyathelo olondolozo luyimfuneko kwinkqubo yokusulungekiswa okuyimfuneko.
