Lub lim tiam dhau los, tus nqi ntawm cov khoom siv raw khoom sib txawv. Hlau ore nqi fluctuated thiab poob, coke cov nqi tseem ruaj khov rau tag nrho, coking thee lag luam nqi tended kom ruaj khov, zoo tib yam alloy nqi yog nruab nrab, thiab tshwj xeeb alloy nqi poob rau tag nrho.Cov nqi hloov ntawm lub ntsiab ntau yam yog raws li nram no. :

Imported hlau ore nqi poob lag luam

Lub lim tiam dhau los, kev ua lag luam ntawm cov khoom siv hlau txawv teb chaws hloov pauv, nrog rau tus nqi ntawm cov phaj sab nrauv thiab cov nqi ntawm qhov chaw nres nkoj poob me ntsis piv nrog rau lub asthiv dhau los, feem ntau yog vim qhov poob qis hauv cov hlau ore xav tau vim yog kev txwv ntau lawm ntawm sab qaum teb steel mills. Nyob rau tib lub sijhawm, steel zeb cov nyiaj tau los yog compressed, hlau ore kev txaus siab ntawm kev yuav khoom tsis siab, feem ntau tuav cov khoom lag luam qis qis khiav hauv xeev.Vim cov ntawv ceeb toom tau txais nyob ib ncig ntawm cov kev txwv ntau lawm, 2021 txhua xyoo cov khoom siv hlau tsis zoo yuav tsum tsis siab tshaj qhov kawg. xyoo, txhais tau hais tias lub thib ob ib nrab ntawm lub steel zeb yuav muaj ib tug loj npaum li cas ntawm ntau lawm txwv, nyob rau hauv lub sij hawm luv luv lub steel zeb tseem tsis tau muaj kev ntsuas tshwj xeeb, hlau ore xav tau tseem kuj siab, tab sis nyob rau hauv lub sij hawm ntev, xws li lub kev siv cov kev txwv ntau lawm, hlau ore thov yuav poob sharply.

Metallurgical coke pauv tus nqi ruaj khov

Lub lim tiam dhau los, kev lag luam hauv tsev metallurgical coke pauv tus nqi kom ruaj khov.

Kev lag luam coking thee yog ruaj khov

Lub lim tiam dhau los, kev lag luam hauv tsev coking thee nqi yog qhov ruaj khov, nrog cov txiaj ntsig sib xyaw hauv qee thaj chaw, thiab feem ntau ntawm cov thee mines uas tau tso tseg cov khoom lag luam tau nquag npaj rov pib tsim khoom.Tam sim no, cov mines cov thee uas tau nres ntau lawm hauv lub ntsiab. Cov chaw tsim khoom tau nquag rov ua haujlwm thiab kev tsim khoom, tab sis feem ntau cov chaw lag luam hauv qab coking muaj qhov xav tau los ntxiv cov khoom cia, thiab cov khoom siv tseem nruj nyob rau yav tom ntej. Nws cia siab tias cov khoom siv hluav taws xob hauv tsev coking thee thawj koom haum tus nqi yuav nce siab nyob rau yav tom ntej, thiab kev lag luam thee nqi sib xyaw.

Ferroalloy nqi sib xyaw

Lub lim tiam dhau los, cov nqi ferroalloy tau sib xyaw.Ferrosilica, silicon manganese nqi tau nce tsis tu ncua, siab carbon ferrochrome nqi tau nce siab; Vanadium nitrogen alloy nqi nce me ntsis, vanadium hlau nqi poob me ntsis, ferromolybdenum nqi tseem poob qis.Tshwj xeeb:

Ferrosilicon cov nqi lag luam tau nce tsis tu ncua.
