Silicon carbide yog siv dav hauv kev lag luam steel raws li kev ua tau zoodeoxidizer thiab carburizing additive. Vim nws cov pa roj carbon ntau thiab silicon cov ntsiab lus, silicon carbide pab txhim kho steel zoo, txo cov slag tsim, thiab txhim khu kev ua tau zoo.
Nyob rau hauv niaj hnub steel ntau lawm, ntau steel mills siv silicon carbide ua lwm yam los yog ntxiv cov ntaub ntawv rau cov tsoos carburizers thiab deoxidizers.Silicon carbide plays ib tug tseem ceeb luag hauj lwm nyob rau hauv steelmaking raws li ib feem ntawm kev dav.silicon carbide siv nyob rau hauv metallurgy.
Dab tsi yog Silicon Carbide siv rau hauv Steelmaking?
Hauv steelmaking, silicon carbide ua haujlwm ntau yam hauv cov txheej txheem metallurgical.
Nws lub luag haujlwm tseem ceeb suav nrog:
- Deoxidizing molten hlau
- Nce cov ntsiab lus carbon
- Txhim kho steel purity
- Txo cov slag tsim
Thaum ntxiv rau molten hlau, silicon carbide reacts nrog hlau oxide thiab pab carbon rau cov hlau da dej.
Hom tshuaj tiv thaiv:
SiC + 2FeO → SiO₂ + 2Fe + C
Cov tshuaj tiv thaiv no pab tshem tawm cov pa oxygen los ntawm cov hlau molten thiab txhim kho tag nrho cov metallurgical efficiency.
Qhov zoo ntawm kev siv Silicon Carbide hauv Steelmaking
Cov pa roj carbon ntau dua
Piv nrog cov tsoos carburizers xws li graphite lossis roj av coke, silicon carbide muabsiab dua carbon rov qab efficiency, feem ntau ncav cuag80–95%.
Qhov no pab cov neeg tsim khoom steel tswj cov qib carbon zoo sib xws thaum tsim khoom.
Txo Slag tsim
Silicon carbide txo qhov tsim ntawm ntau tshaj slag hauv qhov cub.
Lower slag tiam txhais tau tias:
- huv si molten steel
- txhim kho hlau tawm los
- txo nqi refining
Txhim kho Steel Zoo
Qhov sib ntxiv ntawm silicon carbide tuaj yeem txhim kho:
- hlau purity
- mechanical zog
- kev ua haujlwm casting
Qhov no ua rau silicon carbide tshwj xeeb tshaj yog pab tau rau hauvsiab - zoo steel ntau lawm.
Silicon Carbide nyob rau hauv txawv Steelmaking txheej txheem
Feem ntau siv steel millsmetallurgical silicon carbide khoom tsim tshwj xeeb rau kev siv steelmaking.
Silicon carbide tuaj yeem siv rau hauv ntau cov txheej txheem steelmaking, suav nrog:
Electric Arc Rauv (EAF)
Hauv EAF steelmaking, silicon carbide yog siv los ua ob qho tib sideoxidizer thiab carburizer, txhim kho carbon rov qab thiab txo cov ntsiab lus oxygen.
Induction rauv
Induction furnace steel nroj tsuag feem ntau siv silicon carbide kom stabilize cov ntsiab lus carbon thiab txhim kho melting efficiency.
Hloov Steelmaking
Hauv kev hloov pauv cov txheej txheem, silicon carbide tuaj yeem pab ua kom rov ua kom zoo dua qub thiab txhim kho kev tswj cov hlau.
Hom Specifications ntawm Silicon Carbide rau Steelmaking
Cov txheej txheem steel sib txawv xav tau cov qib sib txawv thiab qhov ntau thiab tsawg ntawm silicon carbide.
| Yam khoom | Tus nqi |

Vim li cas Steel Mills Xaiv Silicon Carbide
Ntau tus neeg tsim khoom steel xaiv silicon carbide vim nws muab ob qho tib sisilicon thiab carbon nyob rau hauv ib tug additive.
Qhov kev ua haujlwm dual no ua rau nws muaj txiaj ntsig zoo rau cov txheej txheem metallurgical.
Cov laj thawj tseem ceeb suav nrog:
- txhim kho melting efficiency
- txo zog noj
- tus nqi tsim khoom qis dua
- ruaj khov metallurgical cov tshuaj tiv thaiv
Yog li ntawd, silicon carbide tau dhau los ua cov khoom tseem ceeb hauv kev tsim cov hlau niaj hnub.
