Wazi kangakanani malunga nezigaba ezithathu zenkqubo yokunyibilika kwe Iziko lokunyibilikisa intsimbi?

Namhlanje, masiyiqonde inkqubo yokunyibilika kweziko lokunyibilikisa intsimbi. Inkqubo yokunyibilika kwesithando sokunyibilikisa intsimbi ibandakanya amanqanaba amathathu: ukunyibilika kwentlawulo, ukunyibilika kwe-homogenization, kunye nokufudumeza kwentsimbi etyhidiweyo:

(1) Inqanaba lokunyibilika kwentlawulo. Intlawulo kwiziko lokunyibilikisa intsimbi iqala itshintshe ukusuka kwimo eqinileyo ukuya kwimo yeplastiki ethambileyo. Emva kokuba intlawulo ifakwe kwisithando somlilo, ukwenzela ukukhusela i-furnace lining, umzimba wesithando somlilo uqala ukujikeleza ngokukhawuleza kwaye ngokuthe ngcembe kumacala omabini. Ngaphantsi kwesenzo samandla omatshini kunye nobushushu, intlawulo enkulu yetsimbi ichithwa ngokuthe ngcembe kwiibhloko ezincinci. Xa iqondo lobushushu kwisithando somlilo liphakama ukuya kwindawo yokunyibilika kwesinyithi, indlela enye-indlela eqhubekayo yokujikeleza komzimba wesithando somlilo iphucula umphumo wokudlulisa ubushushu phakathi kwesithando somlilo kunye nentlawulo.

(2) Inqanaba le-homogenization yezithako. I-FeO kunye ne-slagging materials (isanti kunye ne-limestone) eyenziwe kwinqanaba lokunyibilika ifom yokuqala ye-slag, egubungela kwaye ikhusele isinyithi esityhidiweyo. Intlawulo iyatshintsha ukusuka kwimeko yeplastiki ukuya kulwelo, izinto ezidibeneyo ziqala ukunyibilika kwintsimbi etyhidiweyo, kwaye ikhabhoni kwi-recarburizer iqala ukunyibilika kwintsimbi etyhidiweyo. Ngeli nqanaba, umzimba wesithando somlilo uyaqhubeka ujikeleza kwicala elinye, elikhuthaza ukubunjwa kwensimbi etyhidiweyo, kwaye izinto ezifana nekhabhoni, i-silicon kunye ne-manganese zichithwa ngokukhawuleza kwintsimbi etyhidiweyo.

(3) Ukutshisa kakhulu kwentsimbi etyhidiweyo. I-iron etyhidiweyo ishushu kakhulu kwiqondo lokushisa lokucofa, kwaye i-carbon inyibilika ngokupheleleyo kwintsimbi etyhidiweyo. I-slag kunye ne-recarburizer enganyibilikiyo igubungela isinyithi esinyibilikisiweyo, esigqithiswa ngubushushu obuqhutywe ngumbane wesithando somlilo kwaye sifikelele kwiqondo lokushisa.

Umgaqo wokufudumeza intsimbi enyibilikisiweyo kwiziko lokunyibilikisa intsimbi uyafana nowamanye amaziko oshishino. Umgangatho ophezulu wesithando somlilo unobushushu obuphezulu kunye nobushushu obuninzi obuqokelelwe kwisithando somlilo. Xa umzimba wesithando somlilo ujikeleza, ngokuqhubekayo uzisa ubushushu obuqokelelwe kwisithando somlilo esiphezulu kwintsimbi etyhidiweyo ukufezekisa injongo yokutshisa isinyithi esityhidiweyo.
