Nce nyob rau hauv kev faib ua feem ntawm loj-sized ultra-siab fais fab graphite hluav taws xob

1. Kev muaj cov saw ntawm graphite electrode kev lag luam

(1) kev lag luam

Lub ntsiab raw cov ntaub ntawv raw rau graphite cov ntawv yog roj coke thiab koob coke thiab koob coke, nrog cov thee tar suab yog lub ntsiab additive. Cov ntaub ntawv raw rau kev faib ua feem loj ntawm cov nqi tsim tsim ntawm graphite electrodes, cov nyiaj txiag rau ntau tshaj 65%. Ntawm lawv, roj av coke yog cov khoom siv tseem ceeb rau cov khoom siv hluav taws xob zoo li cas rau cov khoom siv raw rau ultra-siab lub zog graphite electrodes.

Roj av coke yog los ntawm cov roj ua kom ua kom zoo dua, uas yog cov khoom khov kho uas tsim los ntawm kev txwv tsis pub siv roj av ua cov khoom siv raw. Nws yog dav siv nyob rau hauv teb xws li graphite electrodes, electrolytic txhuas, iav, thiab nws yog xim hlau silicon; Koob coke yog cov coke zoo nrog cov coefficient ntawm thermal expansion thiab yooj yim graphitization. Nws muaj kev ua haujlwm zoo thiab thermal conductivity, thiab yog tsuas yog siv nyob rau hauv high-zog thiab ultra-siab elecite elecite electrodes thiab cov khoom siv hluav taws xob tsis zoo rau cov roj teeb lithium.

(2) ownstream muaj kev lag luam

Graphite cov ntawv hluav taws xob feem ntau yog siv hauv cov liaj zoo li steelmaking, silicon refining, thiab daj phosphorus ntxiv. Ntawm lawv, Ultra-siab Graphite hluav taws xob yog siv nyob rau hauv ultra-siab graphaking, thiab lub zog hluav taws xob hluav taws xob hluav taws xob hluav taws xob fais fab hluav taws xob fais fab fais fab, silicon Refining, Daj phosphorus kho kom zoo nkauj, thiab lwm yam.

Steel SMELING yog lub ntsiab ntawv thov teb ntawm Graphite electrodes, suav rau txog 80% ntawm tag nrho cov kev noj ntawm graphite electrodes. Kev txhim kho ntawm cov hlau smelting kev lag luam yog ze ze rau kev txhim kho ntawm graphite electrode kev lag luam.

Hauv 2022, lub ntiaj teb crude steel tso tawm yuav qis dua vim muaj kev sib tw txuas ntxiv hauv European thiab Tebchaws Meskas, lub siab ntse hauv lub zog tus nqi thiab lwm yam. Raws li cov txheeb cais ntawm lub ntiaj teb hlau thiab Hlau Koom Haum, Lub Ntiaj Teb Crude Cov zis yuav ncav cuag 1.013 billion tons, ib xyoos nyob rau hauv-xyoo txo ​​ntawm 2.1%. Xyoo 2023, tag nrho lub ntiaj teb crude steel ntau lawm yog 1.888 billion tons, uas tseem nyob twj ywm tsis hloov tsis tau unchanged xyoo. Tag nrho cov hlau uas muaj tag nrho cov stude ntawm 71 lub teb chaws thiab cov cheeb tsam muaj nyob hauv qhov chaw ua haujlwm thoob ntiaj teb yog 1.8497 billion tons, txo me ntsis txo qis 0.1% thawm xyoo. Saib rau ntawm thaj chaw sib txawv, cov khoom lag luam nyoos ntau hauv Europe, North America, thiab South America poob xyoo-rau lwm thaj chaw nce xyoo; Nyob rau hauv cov ntsiab lus ntawm cov teb chaws, ntawm sab saum toj kaum steel ua rau cov teb chaws hauv ntiaj teb, Nyiv, lub teb chaws tau pom lawv cov tebchaws tau pom xyoo, tshwj xeeb yog Is Nrias teb, uas cov zis tawm Kev loj hlob mus txog 11.8%. Raws li cov ntaub ntawv los ntawm Tuam Tshoj Steel Hlau Koom Tes, Tuam Tshoj Crude Steel Ntau Lawm hauv 2023 yog 1019.08 lab tons, tsis hloov xyoo-rau-xyoo; Tab sis nyob rau hauv cov kev taw qhia ntawm "ob lub hom phiaj carbon", lub teb chaws muaj zog tsim hluav taws xob me ntsis steelmaking, uas yog nyob rau hauv kab nrog rau kev txhim kho kev txhim kho thoob ntiaj teb.
