Carbon raiser, tseem hu ua carbon additive los yog carburizer, yog ib yam khoom uas ntxiv rau molten hlau (feem ntau thaum lub sij hawm steelmaking) kom cov pa roj carbon ntsiab lus. Nws ua haujlwm rau ntau lub hom phiaj hauv kev lag luam metallurgical, thiab nws qhov sib ntxiv yog qhov tseem ceeb hauv kev ua tiav cov khoom tshwj xeeb hauv cov khoom kawg. Cov pa roj carbon monoxide feem ntau yog tsim los ntawm cov pa roj carbon monoxide thiab tej zaum yuav muaj lwm yam nyob ntawm qhov chaw thiab cov txheej txheem tsim khoom.
Nov yog qee qhov tseem ceeb ntawm carbon raisers:
1. Cov ntsiab lus carbon:Lub hom phiaj tseem ceeb ntawm kev ntxiv cov pa roj carbon monoxide yog ua kom cov pa roj carbon ntau ntawm cov hlau molten. Qhov no yog qhov tseem ceeb tshwj xeeb hauv steelmaking, qhov tseeb ntawm kev tswj hwm cov ntsiab lus ntawm cov pa roj carbon monoxide yog qhov tseem ceeb rau kev ua tiav qhov xav tau cov khoom siv kho tshuab thiab tshuaj lom neeg hauv cov khoom hlau kawg.
2. Tus neeg sawv cev txo qis:Carbon raisers ua raws li txo cov neeg ua haujlwm hauv qee cov txheej txheem metallurgical. Lawv hnov mob nrog oxides hauv cov hlau molten, xws li hlau oxide, thiab pab txo lawv mus rau hauv daim ntawv hlau. Qhov no yog qhov tseem ceeb hauv cov txheej txheem xws li steelmaking qhov twg txo cov hlau ore yog ib kauj ruam tseem ceeb.
3. Kho Alloy Composition:Dhau li ntawm cov pa roj carbon, cov pa roj carbon monoxide yuav muaj lwm cov ntsiab lus xws li sulfur, nitrogen, thiab tshauv. Qhov sib xyaw ntawm cov pa roj carbon monoxide tuaj yeem cuam tshuam rau tag nrho cov khoom ntawm cov hlau.
4. Kev tswj cov txheej txheem melting:Qhov sib ntxiv ntawm cov pa roj carbon raiser tuaj yeem cuam tshuam cov txheej txheem melting los ntawm kev txhawb nqa cov cua sov thiab pab hauv kev tawg ntawm cov ntsiab lus alloying.
Feem ntau qhov chaw ntawm carbon raisers muaj xws li calcined petroleum coke, anthracite thee, thiab graphite. Kev xaiv ntawm carbon raiser nyob ntawm seb cov kev cai tshwj xeeb ntawm cov txheej txheem metallurgical thiab cov khoom xav tau hauv cov khoom kawg.
Hauv cov ntsiab lus, carbon raisers ua lub luag haujlwm tseem ceeb hauv kev kho cov ntsiab lus carbon, txhawb kev txo qis, thiab cuam tshuam cov khoom ntawm cov hlau molten hauv ntau cov txheej txheem metallurgical, tshwj xeeb tshaj yog nyob rau hauv steelmaking.
