Nrog rau tus nqi siab ntawm graphite electrodes thiab qhov kev xav tau qis qis, kev xav hauv kev lag luam graphite electrode tau sib txawv tsis ntev los no. Ntawm qhov tod tes, cov khoom lag luam tsis ntev los no thiab kev xav tau tseem tab tom qhia txog kev ua si tsis txaus ntseeg, thiab qee lub tuam txhab graphite electrode tseem muaj lub siab xav xa khoom thiab ntim khoom; Ntawm qhov tod tes, cov nqi tsim khoom ntawm graphite electrodes yog siab, thiab tag nrho cov txiaj ntsig kev lag luam tsis txaus. Txhawm rau kom tsis txhob muaj tus nqi hloov pauv, Graphite electrode tuam txhab lag luam kuj txaus siab rau tus nqi ruaj khov.
Raws li lub Cuaj Hlis 6, 2021, tus nqi tseem ceeb ntawm graphite electrodes hauv Suav teb nrog lub cheeb ntawm 300-600mm: lub zog zoo tib yam 15000-18000 yuan / tuj; siab zog 17000-20500 yuan/ton; ultra-siab zog 17000-25000 yuan / tuj; Ultra-high-power 700mm graphite Electrode 27000-30000 yuan / tuj. Tus nqi nruab nrab ntawm kev lag luam ntawm cov khoom siv hluav taws xob tseem ceeb hauv Suav teb yog 20,286 yuan / ton, qhov txo qis ntawm 7.49% ntawm tib lub sijhawm lub hli dhau los, nce 29.98% txij thaum pib ntawm lub xyoo, thiab nce 54.10% ntawm tib lub sijhawm xyoo tas los. .
Kev kub siab ntawm tus nqi ntawm graphite electrodes:
1. Tus nqi ntawm koob coke thiab thee pitch nyob rau hauv lub upstream ntawm graphite electrodes yog siab, thiab tus nqi ntawm cov roj av uas tsis muaj sulfur coke tseem nce, tsav lub siab ntawm tus nqi ntawm graphite electrodes kom nce.
2. cuam tshuam los ntawm tej yam xws li lub hwj chim curtailment nyob rau hauv Inner Mongolia thiab dej nyab nyob rau hauv Henan, thiab attracted los ntawm lub siab cov nyiaj tau los ntawm tsis zoo electrode graphitization, ib feem ntawm lub graphite electrode graphitization muaj peev xwm hloov mus rau qhov tsis zoo electrode graphitization muaj peev xwm. Graphite electrode graphitization cov peev txheej nruj, thiab graphite electrode ci, Graphitization cov nqi tau nce.
Tag nrho cov kev xav ntawm graphite electrode kev lag luam yog muab faib. Txij li thaum tus nqi qis-sulfur petroleum coke poob rau lub Tsib Hlis, qee lub tuam txhab me me thiab nruab nrab graphite electrode tau txo qis kev tsim khoom raws li kev lag luam tos-thiab-pom kev xav. Nyob rau hauv Lub Xya hli ntuj-September, lub graphite electrode davhlau ya nyob twg cov khoom tiav ua lag luam yog off-season, thiab tus nqi ntawm superimposed raw khoom tseem nce. Qee lub tuam txhab graphite electrode muaj cov phiaj xwm txo qis kev tsim khoom thiab kev tsim khoom, thiab kev tsim khoom pib ntawm graphite electrode kev lag luam tau maj mam noj.
♦ Cov tuam txhab lag luam tseem ceeb tau ua haujlwm ntau dua nyob rau theem pib ntawm kev tsim khoom, thiab tsis ntev los no tau tso tawm lawv lub peev xwm tsim khoom, tsom mus rau kev xa khoom nquag, tab sis cov neeg siv khoom lag luam tseem ceeb ntawm graphite electrode yog qhov ruaj khov thiab tsis muaj qhov tseem ceeb ntawm kev xa khoom.
♦ Ib feem ntawm cov tuam txhab me me thiab nruab nrab graphite electrode muaj kev lag luam qis. Tsis tas li ntawd, vim yog lub caij tawm ntawm qhov kev thov davhlau ya nyob twg, cov tuam txhab tsom mus rau cov khoom xa tuaj, thiab cov nqi sib pauv ntawm tus neeg txiav txim qis me ntsis ntawm kev ua lag luam.
♦ Ib feem ntawm cov tuam txhab graphite electrode nrog kev tsim khoom ruaj khov thiab kev muag khoom thiab cov khoom muag qis, nyob rau hauv tus nqi siab, lub tuam txhab tsis kam muag yog pom tseeb dua. Txhawm rau kom tsis txhob raug nqi hloov pauv, qee lub tuam txhab tau nce me ntsis tus nqi ntawm graphite electrodes.
Ntawm qhov tod tes, cov graphite electrode cov khoom lag luam yuav los ntawm qee cov hluav taws xob hluav taws xob hluav taws xob steel nroj tsuag nyob rau theem pib yog maj mam depleted. Nws tau tshaj tawm tias qee qhov hluav taws xob cua sov steel cov nroj tsuag muaj kev npaj yuav khoom nyob rau yav tom ntej.
Ntawm qhov tod tes, raws li tus nqi ntawm cov khoom siv raw khoom ntawm graphite electrodes tseem nce ntxiv, qee qhov hluav taws xob rau hluav taws xob steel mills thiab qee cov graphite electrode cov tub lag luam ntseeg tias tus nqi ntawm graphite electrodes nyob ze rau ntawm qhov rov qab, thiab downstream ntawm graphite electrodes yog nquag. yos hav zoov nram qab. Txawm li cas los xij, nyob rau hauv lub siab ntawm tus nqi ntawm graphite electrode tuam txhab uas muag, muaj Reluctant muag cov kev xav.
Tsis tas li ntawd, lub caij ntuj sov huab cua kub yuav dhau mus, lub caij tawm ntawm graphite electrode davhlau ya nyob twg cov khoom tiav tiav kev ua lag luam yuav dhau mus, thiab cov khoom lag luam tsis ntev los no yuav muaj zog, txhawb kev lag luam, kev khiav hauj lwm tus nqi hluav taws xob cua sov steel nroj tsuag. tau rebounded me ntsis, thiab qhov kev thov rau graphite electrodes tau nce.
Tsis ntev los no, cov lag luam downstream ntawm graphite electrode nquag coj cov khoom los ntawm hauv qab ntawm pawg ntawm graphite electrode nqi siab, muaj qee yam tsis kam muag cov lag luam graphite electrode. Raws li qhov xwm txheej ntawm tus nqi siab thiab kev xav tau zoo hauv kev lag luam hauv qab ntawm silicon hlau, tus nqi ntawm cov khoom siv hluav taws xob zoo tib yam thiab siab zog graphite electrode tau coj los ua kom rov zoo dua, thiab cov lag luam graphite electrode uas tsis tshua muaj cov khoom lag luam kuj tau nce me ntsis tus nqi ntawm ultra-siab. lub zog graphite electrode. Nrog rau kev siv ntxiv ntawm graphite electrode kev lag luam cov khoom lag luam, nws xav tias nyob rau nruab nrab ntawm 9 tom qab kawg ntawm kev sib tw steel, graphite electrode cov nqi yuav rov zoo dua.
