Lub lim tiam dhau los, tus nqi ntawm cov khoom siv raw hauv tebchaws tau hloov pauv. Tus nqi hlau ore tau hloov pauv thiab poob qis, tus nqi coke tseem ruaj khov rau tag nrho, tus nqi lag luam coking coal feem ntau ruaj khov, tus nqi alloy ib txwm muaj kev ruaj khov nruab nrab, thiab tus nqi alloy tshwj xeeb poob qis rau tag nrho. Kev hloov pauv tus nqi ntawm cov hom tseem ceeb yog raws li nram no:

Cov nqi hlau txawv teb chaws poob siab ua haujlwm

Lub lim tiam dhau los, kev ua lag luam ntawm cov hlau ore xa tuaj tau hloov pauv, nrog rau tus nqi ntawm cov phaj sab nraud thiab tus nqi ntawm chaw nres nkoj poob me ntsis piv rau lub lis piam dhau los, feem ntau yog vim qhov kev poob qis ib ntus ntawm kev thov hlau ore vim yog qhov txwv tsis pub tsim khoom ntawm cov chaw tsim khoom hlau sab qaum teb. Tib lub sijhawm, cov nyiaj tau los ntawm cov chaw tsim khoom hlau tau raug nias, kev txaus siab rau kev yuav khoom hlau ore tsis siab, feem ntau tswj hwm cov khoom muag qis ib txwm khiav. Vim yog daim ntawv ceeb toom tau txais nyob ib puag ncig cov kev cai txwv tsis pub tsim khoom, xyoo 2021 kev tsim khoom hlau nyoos txhua xyoo yuav tsis siab dua li xyoo tas los, txhais tau tias ib nrab ntawm cov chaw tsim khoom hlau yuav muaj qib loj ntawm kev txwv tsis pub tsim khoom, hauv lub sijhawm luv luv cov chaw tsim khoom hlau tseem tsis tau muaj kev ntsuas tshwj xeeb, kev thov hlau ore tseem siab heev, tab sis hauv lub sijhawm ntev, xws li kev siv txoj cai ntawm kev txwv tsis pub tsim khoom, kev thov hlau ore yuav poob qis heev.

Tus nqi pauv pauv ntawm cov tshuaj coke metallurgy ruaj khov

Lub lim tiam dhau los, tus nqi pauv lag luam coke metallurgical hauv tebchaws tau ruaj khov.

Lub khw muag coking coal ruaj khov

Lub lim tiam dhau los, cov nqi lag luam coking thee hauv tsev feem ntau ruaj khov, nrog rau cov txiaj ntsig sib xyaw hauv qee thaj chaw, thiab feem ntau ntawm cov chaw ua haujlwm thee uas tau tso tseg kev tsim khoom tau npaj txhij los rov pib tsim khoom. Tam sim no, cov chaw ua haujlwm thee uas tau tso tseg kev tsim khoom hauv thaj chaw tsim khoom tseem tab tom rov pib ua haujlwm thiab tsim khoom, tab sis feem ntau cov tuam txhab coking downstream muaj qhov xav tau los rov ua kom muaj chaw cia khoom, thiab cov khoom siv tseem nruj heev yav tom ntej. Nws xav tias tus nqi koom haum coking thee hauv tsev feem ntau yuav nce siab yav tom ntej, thiab tus nqi lag luam thee hauv khw sib xyaw.

Cov nqi Ferroalloy sib xyaw

Lub lim tiam dhau los, tus nqi ferroalloy tau sib xyaw. Tus nqi Ferrosilica, silicon manganese nce siab tas li, tus nqi ferrochrome carbon siab nce siab heev; Tus nqi Vanadium nitrogen alloy nce me ntsis, tus nqi vanadium hlau poob me ntsis, tus nqi ferromolybdenum tseem poob qis me ntsis. Tshwj xeeb:

Cov nqi lag luam Ferrosilicon tau nce siab tas li.
