Kev Muab Khoom Thiab Kev Xav Tau Tsis Muaj Zog, Cov Nyiaj Tau Los Ntawm Low-sulfur Calcined Coke Txo Me Ntsis

I. Cov nyiaj tau los ntawm cov coke calcined uas muaj sulfur tsawg tsawg dua 12.6% ntawm lub hli dhau los

Txij li thaum Lub Kaum Ob Hlis, cov roj av thoob ntiaj teb tau hloov pauv, kev tsis paub tseeb ntawm kev ua lag luam tau nce ntxiv, cov neeg ua lag luam tau tos thiab saib ntau dua, cov khoom siv raw cov khoom siv qis sulfur coke xa khoom lag luam tau qaug zog, cov khoom muag tau nce ntxiv, thiab cov nqi tau poob qis qee zaum. Kev ua lag luam qis sulfur calcined coke tau ua raws li kev ua lag luam, thiab cov nqi poob me ntsis. Hauv lub voj voog no, qhov nruab nrab theoretical profit ntawm qis sulfur calcined coke hauv Northeast China yog 695 yuan / ton, uas yog 12.6% qis dua lub lim tiam dhau los. Tam sim no, cov nyiaj tau los ntawm cov tuam txhab calcined yog qhov ruaj khov, tswj hwm ntawm qib nruab nrab mus rau siab. Tus nqi ua lag luam ntawm cov khoom siv raw qis sulfur coke tau txo qis qee zaum, thiab kev ua lag luam rau qis sulfur calcined coke tsis muaj zog thiab ruaj khov, nrog rau kev hloov kho qis qis qee zaum.

Lub lim tiam no, tus nqi ntawm cov coke calcined zoo uas tsis muaj sulfur tseem tsis muaj zog thiab ruaj khov. Tus nqi ntawm cov coke calcined siv Jinxi raw coke ua cov khoom siv raw yog li 8,500 yuan / ton, thiab tus nqi ntawm cov coke calcined siv Fushun raw coke ua cov khoom siv raw yog 10,600 yuan / ton. Kev txaus siab ntawm cov neeg siv khoom los yuav yog qhov nruab nrab, thiab kev ua lag luam tsis muaj zog thiab ruaj khov.

II. Cov khoom siv raw uas tsis muaj sulfur ntau, cov nqi roj av coke hloov pauv hauv qhov ntau thiab tsawg thiab poob qis

Hauv lub voj voog no, kev ua lag luam roj av coke uas muaj cov leej faj tsawg hauv Northeast China muaj kev lag luam tsis hloov pauv, kev xa khoom ntawm cov chaw ua roj qeeb qeeb, cov khoom muag ntawm cov tuam txhab lag luam nce ntxiv, thiab tus nqi roj av coke txuas ntxiv poob qis. Tus nqi teev npe ntawm cov roj zoo 1 # coke yog 6,400 yuan / ton, txo qis txhua hli ntawm 1.98%; tus nqi ntawm cov roj zoo 1 # coke yog 5,620 yuan / ton, txo qis txhua hli ntawm 0.44%. Liaohe Petrochemical qhov kev twv tshiab tau txo qis me ntsis, thiab Jilin Petrochemical tus nqi tau ruaj khov ib ntus hauv lub voj voog no. Tam sim no, kev ua lag luam muaj lub siab xav yuav khoom nce thiab tsis yuav khoom nqis. Kev lag luam carbon qis qis feem ntau nyob ntawm ntug, thiab tsis muaj lub siab xav khaws cov khoom. Cov tuam txhab lag luam khaws cov khoom muag qis, thiab lawv txoj kev txaus siab yuav khoom tsis zoo.

III. Cov chaw tsim khoom siv hluav taws xob graphite electrode hauv qab no tsim cov khoom siv tsawg, thiab qhov kev thov hauv qab no tsis muaj zog

Lub lim tiam no, kev ua lag luam graphite electrode tseem ruaj khov thiab kev xa khoom ruaj khov. Feem ntau cov chaw tsim khoom tswj hwm qhov sib npaug tam sim no. Qhov kev thov tom qab tsis muaj zog, thiab tseem muaj kev tawm tsam kom thawb cov nqi graphite electrode nce. Cov chaw tsim khoom graphite electrode muaj cov khoom tsim khoom tsawg, thiab qhov kev thov tom qab tsis tau nce siab heev. Tsis tas li ntawd, cov txiaj ntsig tsim khoom tsis zoo, thiab cov chaw tsim khoom tsis muaj lub siab xav pib ua haujlwm.

Kev kwv yees yav tom ntej:

Nws xav tias lub lim tiam tom ntej no, qhov kev thov ua lag luam rau cov electrodes graphite yuav tsis zoo dua qub, thiab cov chaw tsim khoom yuav tswj tus nqi thiab sib tham txog kev xa khoom. Hauv lub sijhawm luv luv, qhov kev thov hauv qab no hauv kev lag luam coke calcined uas muaj sulfur tsawg tsis muaj zog, thiab tsis muaj cov yam ntxwv zoo pom tseeb. Tus nqi ntawm cov coke calcined uas muaj sulfur tsawg yuav poob qis hauv qhov ntau thiab tsawg, thiab qhov nyiaj tau los tseem nyob ntawm theem nruab nrab.
