Cov yam ntxwv uas cuam tshuam rau Melting Point ntawm Aluminium

Ntau yam tuaj yeem cuam tshuam qhov melting point ntawm aluminium thiab nws cov alloys:

  • Alloying Elements: Lub xub ntiag ntawm alloying ntsiab xws li tooj liab, magnesium, silicon, thiab zinc tuaj yeem nce lossis txo qhov melting point, nyob ntawm lawv cov kev cuam tshuam nrog txhuas.
  • Cov impurities: Txawm tias muaj pes tsawg tus ntawm impurities tuaj yeem cuam tshuam qhov melting point. Piv txwv li, hlau, uas feem ntau tam sim no raws li impurity, tuaj yeem txo qhov melting point.
  • Thermal History: Lub thermal keeb kwm ntawm aluminium, suav nrog kev kho cua sov yav dhau los lossis kev ua tiav, tuaj yeem kho cov qauv nplej thiab cuam tshuam rau lub melting point.
  • Cov txheej txheem ua haujlwm: Cov txheej txheem sib txawv, xws li sai solidification los yog hmoov metallurgy, tuaj yeem ua rau cov microstructures tsis sib npaug nrog cov ntsiab lus sib txawv.

Kev siv ntawm Aluminium's High Melting Point

Lub siab melting point ntawm aluminium thiab nws cov alloys ua rau lawv haum rau ntau yam kev siv kub:

  • Vuam thiab Brazing: Aluminium lub siab melting point tso cai rau muaj zog vuam thiab brazing cov txheej txheem, uas yog ib qho tseem ceeb nyob rau hauv fabrication ntawm complex qauv thiab cov khoom.
  • Thaum tshav kub kub Exchangers: Lub siab melting point ntawm tej aluminium alloys ua rau lawv zoo tagnrho rau siv nyob rau hauv tshav kub exchangers, qhov twg lawv tuaj yeem tiv taus qhov kub ua haujlwm siab yam tsis muaj melting.
  • Cookware: Aluminium lub siab melting point kuj tseem muaj txiaj ntsig zoo hauv kev tsim khoom noj khoom haus, kom ntseeg tau tias cov lauj kaub thiab cov lauj kaub tuaj yeem tswj tau qhov kub ua noj tsis muaj kev pheej hmoo ntawm melting.

Yuav ua li cas Aluminium lub Melting Point piv rau lwm yam hlau

Thaum piv nrog lwm cov hlau, lub melting point ntawm aluminium tsis siab. Ntawm no yog kev sib piv ntawm cov ntsiab lus melting ntawm txhuas nrog ob peb lwm yam hlau:

Hlau Melting Point (°C) Melting Point (° F)
Aluminium 660.32 1220.58
Tooj 1085 1981
Hlau 1538 2800
Zinc 419 776
Hlau 1370 – 1520 (txawv) 2502 – 2760 (txawv)

Qhov kev sib piv no qhia tau hais tias thaum aluminium muaj qhov qis qis dua li cov hlau xws li hlau thiab hlau, nws yog siab tshaj zinc thiab ntau lwm yam hlau. Qhov no tso aluminium rau hauv txoj haujlwm zoo rau cov ntawv thov uas yuav tsum muaj qhov sib npaug ntawm qhov kub thiab txias thiab kev ua haujlwm.

Hauv kev xaus, lub melting point ntawm txhuas yog ib qho tseem ceeb cov cuab yeej uas cuam tshuam nws siv nyob rau hauv ntau yam lag luam. Nkag siab txog yam uas cuam tshuam rau cov cuab yeej no thiab nws piv rau lwm cov hlau li cas yog qhov tseem ceeb rau kev xaiv cov khoom thiab cov txheej txheem optimization. Aluminium lub siab melting point, ua ke nrog nws lwm yam khoom muaj txiaj ntsig, ua rau nws muaj ntau yam khoom siv rau ntau yam kev siv.
