Inzira nyamukuru yisoko
Kongera umusaruro wibyuma ukoresheje tekinoroji ya Arc Furnace
- Itanura ryamashanyarazi arc rifata ibyuma, DRI, HBI (icyuma gishyushye gishyushye, gikomatanya DRI), cyangwa icyuma cyingurube muburyo bukomeye, hanyuma kigashonga kugirango kibyare ibyuma. Mu nzira ya EAF, amashanyarazi atanga imbaraga zo gushonga amatungo.
- Graphite electrode ikoreshwa cyane cyane mumashanyarazi ya arc (EAF) mugukora ibyuma, kugirango bishongeshe ibyuma. Electrode ikozwe muri grafite kubera ubushobozi bwayo bwo guhangana nubushyuhe bwo hejuru. Muri EAF, isonga rya electrode irashobora kugera kuri 3000º Fahrenheit, ni kimwe cya kabiri cyubushyuhe bwubuso bwizuba. Ubunini bwa electrode buratandukanye cyane, kuva kuri 75mm z'umurambararo, kugeza kuri 750mm z'umurambararo, no kugera kuri 2.800mm z'uburebure.
- Kwiyongera kw'ibiciro bya electrode ya grafite yazamuye ibiciro bya EAF. Ugereranyije EAF igereranya gukoresha kg 1.7 za electrode ya grafite kugirango itange toni imwe yicyuma.
- Kuzamuka kw'ibiciro biterwa no guhuriza hamwe inganda, ku isi hose, guhagarika ubushobozi mu Bushinwa, nyuma y’amabwiriza y’ibidukikije, no kuzamuka kw’umusaruro wa EAF, ku isi hose. Ibi bivugwa ko bizamura igiciro cy’umusaruro wa EAF ku kigero cya 1-5%, bitewe n’imikorere y’amasoko, kandi ibyo birashoboka ko byagabanya umusaruro w’ibyuma, kuko nta cyasimburwa na electrode ya grafite mu bikorwa bya EAF.
- Byongeye kandi, politiki y’Ubushinwa mu kurwanya ihumana ry’ikirere yashimangiwe n’igabanuka rikomeye ry’amasoko, atari urwego rw’ibyuma gusa, ahubwo n’amakara, zinc, n’izindi nzego zitera umwanda. Kubera iyo mpamvu, umusaruro w’ibyuma mu Bushinwa wagabanutse cyane mu myaka yashize. Ariko, ibi biteganijwe ko bizagira ingaruka nziza kubiciro byibyuma ninganda zicyuma mukarere, kugirango zishimire ibyiza.
- Ibintu byose bimaze kuvugwa, byitezwe gutwara isoko ya grafite ya electrode mugihe cyateganijwe.
Agace ka Aziya-Pasifika Kuganza Isoko
- Agace ka Aziya-Pasifika yiganjemo umugabane w isoko ku isi. Ubushinwa bufite umwanya munini mubijyanye no gukoresha no gutanga umusaruro wa electrode ya grafite mu isi yose.
- Inshingano nshya za politiki i Beijing no mu zindi ntara zikomeye mu gihugu zihatira abakora ibyuma gufunga ubushobozi bwa toni miliyoni 1.25 z’ibyuma byakozwe binyuze mu nzira yangiza ibidukikije hagamijwe kubyara ingufu nshya za toni miliyoni imwe y’ibyuma. Politiki nkiyi yashyigikiye ihinduka ryabakora muburyo busanzwe bwo gukora ibyuma muburyo bwa EAF.
- Umusaruro ugenda wiyongera ku binyabiziga bifite moteri, hamwe n’inganda ziyongera mu iyubakwa ry’imiturire, biteganijwe ko bizashyigikira icyifuzo cy’imbere mu gihugu ku bicuruzwa bitarimo fer na fer ndetse n’ibyuma, kikaba ari ikintu cyiza cyo kuzamuka kwa electrode ya grafite mu myaka iri imbere. .
- Ubushobozi bwo gukora ubu bwa UHP grafite electrode mu Bushinwa ni toni metero ibihumbi 50 ku mwaka. Icyifuzo cya electrode ya UHP mu Bushinwa nacyo giteganijwe kuzamuka cyane mu gihe kirekire kandi n’ubushobozi bw’inyongera bwa toni zirenga ibihumbi 50 za metero za UHP grafite electrode biteganijwe ko buzabonwa n’icyiciro cya nyuma cy’igihe giteganijwe.
- Ibintu byose byavuzwe haruguru, biteganijwe ko byongera ubushake bwa electrode ya grafite mu karere mugihe cyateganijwe.
