1. High Carbon Silicon yog dab tsi?
High Carbon Silicon yog ib yam khoom los ntawm - khoom tsim thaum lub sij hawm metallurgical txheej txheem ntawm silicon hlau tsim nyob rau hauv smelting furnaces. Nws yog cov khoom sib xyaw ua ke uas sib xyaw ua ke ntawm silicon thiab carbon ntsiab lus, sib koom ua ke deoxidizing thiab alloying peev xwm ntawm silicon nrog cov khoom carburizing ntawm carbon.
2. Cov yam ntxwv tseem ceeb thiab qhov zoo
Tus nqi tseem ceeb ntawm High Carbon Silicon nyob rau hauv nws cov silicon siab thiab siab carbon cov ntsiab lus, kuj tsis tshua muaj nqi, thiab siab economic nqi.
Tus nqi tseem ceeb: Muab piv rau cov txheej txheem ib txwm siv ntawm silicon hlau rau alloying thiab tom qab ntawd ntxiv carburizers (xws li calcined thee lossis graphite), ncaj qha siv High Carbon Silicon ua tiav ob qho tib si alloying thiab carburization hauv ib kauj ruam. Qhov no ua kom yooj yim rau kev khiav lag luam, txo lub sijhawm smelting, thiab txo cov nqi tsim khoom.
Ua tau zoo Carburizer: Cov pa roj carbon hauv High Carbon Silicon muaj nyob rau hauv daim ntawv ntawm cov pa roj carbon monoxide ruaj khov, nrog cov txiaj ntsig siab thiab ruaj khov - feem ntau siab dua 90% - deb tshaj ntawm cov carburizers zoo tib yam. Qhov no ua rau muaj kev tswj xyuas meej dua ntawm cov ntsiab lus carbon hauv molten steel lossis hlau.
Hwj chim Deoxidizer: Silicon nws tus kheej yog lub zog deoxidizing caij. Thaum High Carbon Silicon yog ntxiv rau cov hlau molten, nws tshem tawm cov pa oxygen, txhim kho cov purity ntawm cov hlau.
Txhim kho cov khoom ua tau zoo: Los ntawm kev sib ntxiv ntawm High Carbon Silicon, lub microstructure ntawm cov khoom hlau zaum kawg lossis castings tuaj yeem ua kom zoo, yog li txhim kho lawv lub zog, hardness, thiab hnav tsis kam.
Kev siv hluav taws xob tsawg: Hauv kev lag luam foundry, tshwj xeeb tshaj yog thaum lub sij hawm cam khwb cia hlau smelting, qhov sib ntxiv ntawm High Carbon Silicon txhawb graphitization thiab txhim kho cov fluidity ntawm molten hlau, uas yuav txo tau cov hluav taws xob lub zog uas yuav tsum tau rau melting.
3. Cov cheeb tsam tseem ceeb ntawm daim ntawv thov
High Carbon Silicon feem ntau yog siv hauv cov haujlwm hauv qab no:
Steelmaking kev lag luam:
Raws li ib tug deoxidizer: Siv nyob rau hauv ladle refining rau deoxidize molten hlau.
Raws li ib tug carburizer: Siv nyob rau hauv hluav taws xob arc rauv los yog induction rauv steelmaking kom raug kho cov pa roj carbon ntsiab lus ntawm molten steel, tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov high - carbon steel.
Kev lag luam Foundry (Cast Iron):
Qhov no yog qhov chaw thov tseem ceeb heev rau High Carbon Silicon. Hauv kev tsim cov hlau nplaum thiab cov hlau grey, nws ua haujlwm ua ob qho tib si inoculant thiab carburizer. Nws tsis tsuas yog ua kom zoo dua cov ntsiab lus carbon thiab txhawb nqa graphite nag lossis daus thiab spheroidization tab sis kuj txhim kho qhov kev ua tau zoo ntawm cov hlau molten, txo qhov tsis xws luag, thiab thaum kawg tsim cov castings nrog zoo heev graphite morphology thiab txhua yam khoom.
