Alloy cored hlau yog cov khoom siv hlau uas feem ntau siv nyob rau hauv cov txheej txheem steelmaking ntxiv cov kab hlau rhuav tshem cov hlau molten rau lub hom phiaj ntawm alloying, deoxidizing, desulfurizing thiab inclusions kho. Cov tub ntxhais hlau yog cov khoom siv sib xyaw uas nws cov tub ntxhais muaj cov ntsiab lus sib txawv thiab nws sab nrauv yog qhwv nrog steel sawb lossis lwm yam khoom siv hlau.
Alloy Cored hlau muaj pes tsawg leeg thiab qauv
- Cov Txheej Txheem Txheej Txheem: Raws li kev siv sib txawv, cov ntsiab lus tseem ceeb tuaj yeem muaj ntau yam alloying ntsiab lus, xws li calcium, titanium, vanadium, aluminium, silicon, barium, manganese, magnesium, chromium thiab lwm yam.
- Sab nrauv wrapping: Cov ntaub ntawv xws li steel daim kab xev los yog cov tawv nqaij txhuas feem ntau yog siv los ua txheej txheej txheej sab nraud los tiv thaiv cov tub ntxhais alloying Cheebtsam thiab tiv thaiv kom tsis txhob muaj pa oxygen lossis ya raws hauv huab cua.
alloy cored hlau tseem ceeb muaj nuj nqi
Alloy tub ntxhais hlau ua lub luag haujlwm tseem ceeb hauv kev tsim steel, feem ntau suav nrog cov hauv qab no:
- Alloying: Qhov sib ntxiv ntawm cov ntsiab lus alloying xav tau rau cov hlau los hloov cov tshuaj muaj pes tsawg leeg ntawm cov hlau thiab muab nws lub cev thiab tshuaj lom neeg. Piv txwv li, los ntawm kev ntxiv vanadium lossis niobium lub zog thiab hnav tsis kam ntawm cov hlau tuaj yeem nce ntxiv.
- Deoxygenation: Piv txwv li, cored hlau uas muaj cov ntsiab lus xws li txhuas lossis calcium tuaj yeem ua rau cov pa oxygen hauv cov dej steel los tsim cov oxides, yog li ua tiav deoxygenation thiab txhim kho cov purity ntawm cov hlau.
- Desulfurization: Cov ntsiab lus xws li calcium thiab barium tuaj yeem cuam tshuam nrog sulfur los tsim sulfide, yog li txo cov sulfur ntsiab lus hauv cov hlau thiab txhim kho cov ductility thiab tiv thaiv kev tawg ntawm cov hlau.
- Ua kom zoo nplej: Qee cov ntsiab lus alloying xws li titanium, niobium, thiab lwm yam tuaj yeem txhawb cov nplej ua kom zoo ntawm cov hlau thiab txhim kho cov tawv tawv thiab cov khoom siv ntawm cov hlau.
- Kev kho mob suav nrog: Calcium, magnesium thiab lwm yam tuaj yeem ua rau cov hlau tsis muaj hlau nyob hauv cov hlau los hloov cov inclusions 'morphology, txo lawv qhov loj me, thiab txhim kho lub toughness thiab cuam tshuam cov hlau.
alloy cored hlau hom
Raws li qhov sib txawv ntawm cov khoom sib txawv, alloy cored hlau tuaj yeem muab faib ua pawg hauv qab no:
- Calcium cored hlau: feem ntau yog siv rau deoxygenation thiab desulfurization los txhim kho qhov zoo thiab fluidity ntawm hlau.
- titanium cored hlau: siv los kho cov nplej thiab txhim kho qhov hnav tsis kam thiab hardness ntawm hlau.
- Aluminium cored hlau: siv rau deoxidation, suav nrog kev kho mob thiab txhim kho toughness ntawm hlau.
- Vanadium cored hlau: siv los txhim kho lub zog thiab hnav tsis kam ntawm cov hlau, feem ntau yog siv rau hauv cov qauv hlau muaj zog.
- Calcium silicate cored hlau: muaj zog deoxidation thiab desulfurization muaj peev xwm, haum rau siab purity steel ntau lawm.
