Vim li cas Steel Mills Xaiv Tsawg Sulfur GPC
Rau steel mills, lub recarburizer tsis yog tsuas yog siv los tsa cov pa roj carbon. Qhov kev txhawj xeeb tiag tiag yog seb cov pa roj carbon puas tuaj yeem nqus tau tsis tu ncua yam tsis nqa cov sulfur, nitrogen, tshauv lossis cov teeb meem tsis haum rau hauv cov yaj.
Qhov no yog vim li cas ntau cov nroj tsuag steel xaivTsawg sulfur GPC. Piv nrog cov pa roj carbon monoxide zoo tib yam, graphitized petroleum coke feem ntau muaj cov pa roj carbon ntau dua, qis dua sulfur thiab tus cwj pwm zoo dua. Nws yog qhov tseem ceeb tshwj xeeb tshaj yog thaum cov nroj tsuag siv cov khoom seem siab thiab xav tau coj cov pa roj carbon rov qab rau hauv lub hom phiaj.
HauvEAF steelmaking, carbon tswj ua rhiab heev thaum cov khoom hloov pauv zoo. Yog hais tias lub recarburizer muaj cov sulfur tsis ruaj khov lossis cov tshauv siab, cov nroj tsuag yuav xav tau kev kho ntxiv tom qab. Ib qho ruaj khovsiab carbon recarburizerpab txo qhov kev pheej hmoo.
Hom Specification ntawm Tsawg Sulfur GPC

Rau steel mills, cov khoom tseem ceeb tshaj plaws yog feem ntautsau carbon, sulfur, nitrogen thiab particle loj. Tsau carbon txiav txim siab cov pa roj carbon zoo. Sulfur thiab nitrogen cuam tshuam rau steel zoo tswj. Particle loj cuam tshuam rau kev nqus ceev thiab tuav poob.
Vim li cas Tsawg Sulfur Matters hauv Steelmaking
Sulfur yog ib qho ntawm cov laj thawj tseem ceeb ntawm steel mills xyuas GPC ua tib zoo ua ntej xaj.
Yog hais tias leej faj nyob rau hauv lub recarburizer siab, nws nkag mus rau hauv cov hlau molten ua ke nrog carbon. Tom qab ntawd cov nroj tsuag yuav xav tau kev ua haujlwm desulfurization ntau dua, hloov slag ntau dua lossis ntau lub sijhawm ua kom zoo dua. Rau cov qib nrog sulfur txwv, qhov no dhau los ua qhov teeb meem ncaj qha.
Tsawg sulfur GPC, feem ntau nrogS 0.05% max, muab cov nroj tsuag ntau chav los tswj cov sulfur kawg. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum txoj kev steelmaking twb muaj sulfur siab los ntawm seem, kub hlau lossis lwm yam khoom siv.
Tus nqi qis dua - tus nqi recarburizer yuav zoo li ntxim nyiam thaum xub thawj, tab sis yog tias kev tswj hwm sulfur yuav nyuaj dua tom qab, tus nqi tiag tiag yuav siab dua li qhov xav tau.
Yog vim li cas High Fixed Carbon pab Carbon rov qab
Steel mills siv lub recarburizer los tsa cov pa roj carbon zoo. Rau lub hom phiaj no, taag carbon yog thawj tus naj npawb buyers check.
Tsawg sulfur GPC feem ntau muajTsau Carbon 98.5% min. Qhov no txhais tau tias cov nroj tsuag ntxiv cov pa roj carbon zoo dua thiab tsawg dua uas tsis yog -carbon residue. Piv nrog rau qis dua - cov ntaub ntawv carbon qib, GPC tuaj yeem txo cov hmoov tshauv tawm thiab ua kom cov pa roj carbon hloov tau ntau dua.
Hauv kev ua haujlwm EAF raug siv ntau dua cov hlau, cov molten da dej yuav luv luv ntawm cov pa roj carbon ua ntej kev hloov kho zaum kawg. Ib qho ruaj khov siab carbon recarburizer pab tus neeg teb xov tooj coj cov pa roj rov qab mus rau hauv ntau yam tsis ntxiv cov khoom siv ntau dhau.
Rau cov nroj tsuag uas tsim cov pa roj carbon steel, alloy steel lossis foundry hlau, qhov no txhim kho cov qauv kev suav thiab txo cov kev hloov kho dua.
Particle Loj: Muab nws rau lub qhov cub
GPC particle loj yuav tsum phim txoj kev pub mis thiab qhov cub.
| Loj | Siv dav | Lus Ceeb Toom |
|---|---|---|
| 0-1 hli | Kev kho kom zoo los yog sib tov | Cov tshuaj tiv thaiv sai tab sis hmoov av ntau dua |
| 1-3 hli | Kev siv hluav taws xob induction thiab qhov chaw tsim khoom | Kev sib npaug zoo ntawm kev nqus thiab tuav |
| 1-5 hli | Steelmaking thiab casting | Common loj rau ruaj khov khaws cia |
| 1-10 hli | EAF lossis loj dua qhov cub siv | Haum rau ntau ntxiv |
| Customized | Raws li kev pub mis | Paub meej ua ntej hais |
Cov hmoov ntau dhau tuaj yeem hlawv tawm lossis tsim cov plua plav ua ntej nqus tag nrho. Cov khoom loj loj tuaj yeem yaj maj mam thiab ncua kev hloov pauv carbon. Rau ntau steel mills,1-5mm los yog 1-10mmyog siv tau ntau tshaj cov hmoov zoo heev.
Ib qho lojgraphitized petroleum coke tsumyuav tsum paub meej tias daim ntawv thov ua ntej qhia qhov loj.
Qhov twg Low Sulfur GPC siv
Tsawg sulfur GPC feem ntau siv hauv:
| Daim ntawv thov | Vim li cas GPC thiaj siv |
|---|---|
| EAF steelmaking | Nce cov pa roj carbon thaum cov khoom seem siab |
| Kev kho tus ntaiv | Pab kho carbon kawg |
| Foundry ntau lawm | Txhawb cov pa roj carbon tswj hauv cov hlau grey thiab cov hlau nplaum |
| Alloy steel ntau lawm | Muab cov pa roj carbon ntshiab huv |
| Casting nroj tsuag | Txhim kho cov pa roj carbon monoxide nrog qis impurity input |
Hauv steel mills, kev siv tseem ceeb yog kev hloov kho carbon. Hauv cov chaw tsim khoom, GPC feem ntau raug xaiv vim nws muab cov pa roj carbon ntau thiab qis dua cov sulfur, uas muaj txiaj ntsig zoo rau cov hlau nplaum thiab ntau dua - zoo castings.
