Das hlau - ib qho txheej txheem tseem ceeb hauv kev lag luam Machinery

Ciajtaws hlau, tseem hu ua codular cam khwb cia hlau los yog spheroid graphite hlau almoy uas tau txhim kho ductility thiab kev nruj vim yog cov kab mob me me. Zas cov hlau feem yog siv ntau nyob rau hauv ntau yam kev thov hla kev lag luam xws li kev lag luam, roj thiab roj av, kev siv ua liaj ua teb. Feem ntau ntawm covTsheb Chassis Qhov ChawthiabKev ncua chawyog hlau hlau. Nws muab lub zog, durability, cuam tshuam kuj, corrosion tsis kam thiab nqi-ua hauj lwm zoo rau cov khoom siv hluav taws xob ntxiv.

Ib qho ntawm cov ntsiab lus tseem ceeb ntawm cov yas zeb av yog lawv lub zog siab thiab kav ntev. Lawv muaj peev xwm tiv thaiv cov khoom siv hnyav thiab kev ua haujlwm zoo tagnrho rau kev siv hauv cov ntawv thov uas xav tau cov khoom siv muaj zog, xeb, thiab cuam tshuam.

Ntxiv mus, zas zeb cov khoom muaj cov khoom siv zoo thiab yooj yim rau kev nrum, uas ua rau lawv raug nqi xws li hlau lossis txhuas. Lawv kuj yog cov tseem siab dua, ua kom nws tsim cov khoom nrog cov duab ua nyuaj thiab tsim qauv.

Zas cov hlau feem tau dhau los ua kev xaiv nrov rau cov ntawv thov uas muaj zog, tshwj xeeb tshaj yog nyob rau hauv cov cuab yeej siv hnyav thiab cov cuab yeej hnyav thiab tshuab siv.

Tus txheej txheem hlau hlau, tseem hu ua Nodular pob zeb cam khwb cia hlau txheej txheem lossis spheroid graphate hlau txheej txheem lossis lwm cov ntaub ntawv zoo sib xws rau molten cam khwb cia hlau. Qhov no tsim cov nodules graphite nyob rau hauv cov hlau, uas muab nws nws cov khoom sib txawv.

Tus txheej txheem hlau hlau feem ntau pib nrog melting ntawm cov hlau nyob rau hauv lub cub tawg, tom qab los ntawm kev ntxiv ntawm cov tshuaj magnesium. Cov tshuaj tiv thaiv magnesium nrog cov pa roj carbon hauv cov hlau, ua rau muaj kev tsim ntawm graphite nodules uas yog spherical nyob rau hauv cov duab.

Cov hlau molten yog tom qab ntawd nchuav rau hauv cov pwm thiab tso cai kom txias thiab ua kom txias. Thaum cov hlau pov cov hlau txias thiab ua tau tawm los ntawm cov pwm thiab undergoes cov txheej txheem ua tiav los tshem tawm cov khoom seem.

Ib qho ntawm cov ntsiab lus tseem ceeb ntawm covZas HlauTxheej txheem yog tias nws tso cai rau kev tsim cov duab thiab tsim qauv. Tsis tas li ntawd, zas zeb cov khoom tuaj yeem tsim kho ntawm tus nqi qis dua lwm cov ntaub ntawv xws li hlau, ua tus txheej txheem no yog cov kev lag luam zoo nkauj hauv ntau yam kev lag luam.
