Dab tsi yog melting taw tes ntawm hlau?
Hlau yog ib qho ntawm cov muaj ntau tshaj plaws thiab cov hlau siv dav hauv ntiaj teb. To taub nws cov khoom thermal - tshwj xeeb yog nwsmelting point-Yog tseem ceeb hauv Metallurgy, kev tsim khoom, thiab engineering.
Melting taw tes ntawm hlau
TusMelting taw tes ntawm hlauyog kwv yees li1,538 degree (2,800 degree f)Cov. Qhov no zoo melting kub ua rau cov hlau ib qhov zoo tshaj plaws hauv paus rau kev tsim khoomhlauthiab lwm yamKev kub-alloys.
Vim li cas thiaj li melting point ntawm hlau tseem ceeb?
Hlau ntau lawm: Hlau lub siab pom zoo tso cai rau nws yuav tsum tau txuam nrog carbon thiab lwm yam ntawm cov kub kom ua cov qib sib txawv.
Casting & Forging: Hauv kev siv hlau ua haujlwm, paub qhov tseeb melting point pab tswj cov txheej txheem cua sov thaum lub sijhawmsmelting, chaw ua casuming, thiabkev zam.
Kev Siv Cov Tshuab: Hlau thiab nws cov alloys tau siv nyob rau hauv cov chaw ib puag ncig uas muaj kev kub hnyav heev - xws liAutomotive Xyaw, Aerospace Cheebtsam, thiabMuaj Cov Furnaces.
Yam uas cuam tshuam rau cov yas suab nkauj melting
Kev coj dawb huv: Impurities xws li carbon lossis leej faj tuaj yeem hloov me ntsis hloov cov kub yaj.
Nyem: Raws li nyob rau hauv kev kub siab, lub ntsiab lus melt yuav hloov, txawm hais tias qhov sib txawv yog tsawg kawg ntawm cov huab cua.
Sib ntxaws: Thaum hlau ua ke nrog cov ntsiab lus xws li npib tsib xee lossis chromium, lub txiaj ntsig ntawm txoj kev tuaj yeem muaj kev sib txawv yaj.
