1. Tus nqi
Cov yam ntxwv zoo: Tus nqi ntawm cov coke koob uas xa tuaj ntawm Tuam Tshoj tau nce siab los ntawm US $ 100 / ton, thiab tus nqi nce siab yuav raug siv rau lub Xya Hli, uas yuav ua rau tus nqi ntawm cov coke koob zoo hauv Tuam Tshoj ua raws li, thiab tus nqi tsim khoom ntawm cov electrodes graphite muaj zog heev tseem siab.
Cov yam tsis zoo: Tus nqi lag luam roj av coke uas muaj sulfur tsawg tau nce sai dhau thaum ntxov, thiab kev lag luam roj av coke uas muaj sulfur tsawg tau ua haujlwm tsis zoo tsis ntev los no, thiab tus nqi tau maj mam rov qab mus rau qhov tsim nyog. Tus nqi ntawm cov roj av calcined uas muaj sulfur tsawg tau qaug zog, ua ke nrog kev xa khoom tsis zoo los ntawm cov chaw ua roj av calcined uas muaj sulfur tsawg, thiab tus nqi kuj tau poob qis, ua rau muaj kev tos thiab pom kev xav hauv kev lag luam graphite electrode.
Tag nrho: Txawm hais tias tus nqi ntawm cov roj av coke uas tsis muaj sulfur tau poob qis, nws tseem muaj 68.12% nce ntxiv rau tib lub sijhawm xyoo tas los; tus nqi ntawm cov coke koob hauv tsev ua cov khoom siv raw rau graphite electrodes yog siab thiab tus nqi ntawm cov coke koob xa tuaj txawv teb chaws tau nce siab. Tam sim no, cov electrodes graphite hauv tsev Tus nqi ntawm cov coke koob yog li 9000-10000 yuan / ton; tus nqi ntawm cov coke koob xa tuaj txawv teb chaws yog li 1600-1800 Asmeskas las / ton. Tus nqi ntawm cov thee pitch hloov pauv ntawm qib siab thiab nyob rau hauv qhov ntau nqaim. Lub suab hloov kho rau cov khoom graphite yog 5650 yuan / ton. , Tus nqi tag nrho ntawm kev lag luam graphite electrode tseem siab.

2. Ntawm sab khoom siv
Nyob rau yav tom ntej no, tseem muaj kev txhawb nqa zoo rau kev muab cov graphite electrodes hauv kev ua lag luam. Cov kev tshuaj xyuas tshwj xeeb yog raws li nram no:
1. Tag nrho cov khoom muag ntawm kev lag luam graphite electrode tseem nyob rau qib qis thiab tsim nyog. Feem ntau cov tuam txhab graphite electrode qhia tias lawv tsis muaj cov khoom muag ntau dhau, thiab kev lag luam graphite electrode tag nrho yeej tsis muaj cov khoom muag thiab kev nyuaj siab.
duab
2. Nws to taub tias qee lub tuam txhab graphite electrode tam sim no qhia tias qee cov lus qhia graphite electrode tsis muaj khoom (feem ntau yog ultra-high power 450mm). Nws tuaj yeem pom tias kev muab cov khoom siv ultra-high power nruab nrab thiab me me tseem tswj hwm lub xeev tsis muaj zog.
3. Raws li cov lus tawm tswv yim los ntawm qee lub tuam txhab graphite electrode tseem ceeb, kev muab cov khoom siv zoo hauv Suav teb tau nruj heev thaum Lub Rau Hli, thiab vim yog kev saib xyuas ntawm lub tuam txhab needle coke hauv United Kingdom txij Lub Ob Hlis mus txog Lub Tsib Hlis, cov needle coke uas tau xa tuaj txog hauv Hong Kong thaum Lub Xya Hli thiab Lub Yim Hli, ua rau Tuam Tshoj xa khoom. Kev muab cov needle coke luv luv. Cuam tshuam los ntawm qhov no, qee lub tuam txhab graphite electrode tseem ceeb tau thaiv kev tsim cov ultra-high-power thiab loj graphite electrodes. Tam sim no, kev muab cov ultra-high-size graphite electrodes hauv kev ua lag luam yog nyob rau hauv lub xeev sib npaug zoo.
4. Cuam tshuam los ntawm kev nce nqi ntawm cov koob coke uas xa tuaj ntawm Tuam Tshoj, qee lub tuam txhab graphite electrode tsis kam muag, thiab sab kev muab khoom ntawm kev lag luam graphite electrode feem ntau tsis muaj zog thiab nruj.
3. Kev thov hauv qab
Cov yam ntxwv zoo
1. Tsis ntev los no, kev ua haujlwm ntawm cov nroj tsuag hluav taws xob hauv qab ntawm cov hluav taws xob graphite electrodes tau ruaj khov, thiab qhov nruab nrab ntawm kev ua haujlwm ntawm cov nroj tsuag hluav taws xob hauv qab yeej ib txwm tswj tau li ntawm 70%, thiab cov hluav taws xob graphite tsuas yog xav tau kom ruaj khov.
duab
2. Kev lag luam xa tawm graphite electrode tau txais kev txhawb nqa tsis ntev los no. Raws li cov ntaub ntawv kev lis kev cai, Tuam Tshoj cov khoom xa tawm graphite electrode yog 34,600 tons thaum lub Tsib Hlis 2021, nce 5.36% txhua hli thiab nce 30.53% txhua xyoo; Tuam Tshoj cov khoom xa tawm graphite electrode tag nrho txij lub Ib Hlis mus txog lub Tsib Hlis 2021 Nws yog 178,500 tons, nce 25.07%. Thiab nws nkag siab tias qee lub tuam txhab graphite electrode kuj tau hais tias lawv cov khoom xa tawm zoo thiab kev lag luam xa tawm ruaj khov.
duab
3. Tsis ntev los no, tus naj npawb ntawm cov cub tawg hauv kev lag luam silicon hlau tau maj mam nce. Txij li thaum Lub Rau Hli 17, tus naj npawb ntawm cov cub tawg hlau silicon tau nce 10 piv rau thaum kawg ntawm lub Tsib Hlis. Tus naj npawb ntawm cov cub tawg hauv Baichuan cov ntaub ntawv yog 652 thiab tus naj npawb ntawm cov cub tawg yog 246. Qhov kev thov rau cov hluav taws xob graphite electrodes tau qhia txog kev nce ntxiv, nruab nrab thiab me me.
Cov yam tsis zoo
1. Hais txog cov hlau fais fab, vim yog lub caij nyoog qeeb hauv kev lag luam tsis ntev los no, kev muag khoom tiav lawm tau raug cuam tshuam, thiab tus nqi ntawm cov khoom tiav lawm tseem tsis muaj zog tsis ntev los no, thiab tus nqi ntawm cov khoom tiav lawm tau poob ntau dua li tus nqi ntawm cov hlau seem nyoos. Cov txiaj ntsig ntawm cov nroj tsuag hlau fais fab tau raug nias, thiab tus nqi ntawm cov roj av coke qis tau poob qis tsis ntev los no. , Cov chaw ua hlau muaj kev tos thiab saib tus nqi ntawm cov electrodes graphite, thiab muaj qee tus cwj pwm txo tus nqi ntawm kev yuav khoom graphite electrode.
2. Tus nqi thauj khoom ntawm cov nkoj xa khoom graphite electrode tseem siab, uas cuam tshuam rau kev xa khoom ntawm graphite electrodes mus rau qee qhov.
Kev Saib Xyuas Kev Lag Luam: Txawm hais tias muaj qee qhov kev tos thiab saib hauv kev lag luam graphite electrode tsis ntev los no, tus nqi tsim khoom tag nrho ntawm kev lag luam graphite electrode tseem siab, thiab kev muab cov graphite electrodes superimposed tseem tsis muaj zog thiab nruj, uas yog qhov zoo rau cov lus hais muaj zog ntawm cov tuam txhab graphite electrode tseem ceeb. Nws xav tias tus nqi ruaj khov tag nrho ntawm kev lag luam graphite electrode yuav ua haujlwm raws li tus Tswv. Tsis tas li ntawd, tus nqi nce ntawm cov koob coke uas xa tuaj txhawb nqa tus nqi ntawm graphite electrodes. Nyob rau hauv kev cuam tshuam ntawm cov tuam txhab graphite electrode tseem ceeb tsis kam muag, lawv tseem muaj kev cia siab rau ultra-high-power loj-loj graphite electrodes.
