Lub melting point ntawm steel

Ua ntej peb yuav tham txog steels, qhia rau peb txhais lub cev lub ntsiab lus ntawm cov qeb ntawm lub melting kub. Nyob rau hauv lub scientific thiab muaj teb tswvyim no yog siv kuj raws li qhov kub ntawm solidification. Lub cev lub ntsiab lus ntawm pawg no yog hais tias qhov no qhia tau hais tias cov kub uas nws muaj nuj nqis yog ib tug kev hloov ntawm lub sau ua ib pawg xeev ntawm lub substance, i.e. nws txoj kev hloov mus los ntawm cov kua rau khoom hauv lub xeev. Nyob rau hauv lub heev taw tes tib yam kub kev hloov tej yam khoom uas yuav ua tau yog nyob rau hauv lub qub los yog nyob rau hauv ib tug txawv lub xeev. Thaum ua ntawv thov ntxiv thaum tshav kub kub ib tug kwv los yog tshuaj yeeb dej caw ua ib tug kua hauv lub xeev, thiab thaum twg lub tshav kub abduction - solidifies. Qhov no Performance index yog xam tau tias yog ib tug ntawm cov tseem ceeb tshaj plaws nyob rau hauv lub system ntawm lub cev thaj chaw ntawm tej yam khoom uas, li no nws yog tsim nyog los noj mus rau hauv tus account (qhov no yog tshwj xeeb yog ib qho tseem ceeb kom nkag siab txog nyob rau hauv relation mus steel), hais tias cov solidification kub yog txaus sib npaug zos rau cov melting kub xwb nyob rau hauv lub rooj plaub thaum peb tham txog txig ntshiab substance.

Raws li yog lub npe hu los ntawm cov ntaub ntawv kawm, cov melting kub ntawm lub steel rau ntau hom kev alloys yog cov sib txawv. Qhov no yog txiav txim los ntawm lub alloy qauv ntawm nws cov constituent Cheebtsam, qhov xwm ntawm tus txheej txheem ntawm zus tau tej cov hlau thiab lwm yam.

Piv txwv li, lub melting kub ntawm steel, muaj raws ntawm ib tug tooj liab-npib tsib xee hlau yog hais txog 1150 ° C. Yog hais tias peb yog nyob rau hauv xws li ib alloy ua rau kom cov npib tsib xee cov ntsiab lus, cov kub yuav sawv, vim hais tias ntawm lub melting point ntawm lub npib tsib xee yog ntau tshaj li uas ntawm tooj liab. Feem ntau, nyob ntawm seb cov tshuaj muaj pes tsawg leeg ntawm lub alloy thiab tus piv ntawm Cheebtsam tam sim no nyob rau ntawd ua tus melting kub yuav ua tau nyob nruab nrab ntawm 1420-1525 ° C, Yog hais tias xws li yuav ua lub steel casting tsim tau ib steel ntau lawm, qhov kub thiab txias yuav tsum tau khaws cia txawm nyob rau hauv 100-150 degrees saum toj no. Ib qho tseem ceeb uas influences melting kub yog theem ntawm carbon cov ntsiab lus nyob rau hauv lub hlau. Yog hais tias nws cov ntsiab lus yog high, qhov kub thiab txias yuav qis thiab, ntsig txog, vice versa - nrog zuj zus lawm kub tus nqi ntawm cov carbon qab.

Ib tug ntau nyob rau hauv cov nqe lus ntawm kev txiav txim qhov muaj nqis ntawm ib tug txheej txheem ntsuas kub melting nyob rau hauv stainless steels. Yog vim li cas rau qhov no yog lawv txoj tshuaj nyob tus yeees. Piv txwv li, steel 1X18H9 hom kheev siv nyob rau hauv kev kho hniav thiab hluav taws xob engineering, yog muaj li, apart hlau, txawm carbon, npib tsib xee, chromium, manganese, titanium thiab silicon. Lawm, lub melting kub ntawm lub stainless steel ntawm no muaj pes tsawg leeg yuav tsum tau txiav txim los ntawm cov khoom ntawm txhua tivthaiv muaj nyob rau hauv nws. From xws li ib tug steel hlau ua hniav, crowns, hniav cuav ntau hom, thiab lwm yam hluav taws xob Cheebtsam. Nws yog ua tau los muab ib daim ntawv teev ntawm ib co ntawm cov khoom muaj los ntawm no stainless steel, nws melting kub ntawm 1460-1500 ° C, yog li ntawd, raws li nyob rau hauv no parameter thiab cov tshuaj nyob tus yeees ntawm cov hlau siv rau nws tshwj xeeb soldering nyiaj solders.

Ib qho ntawm feem high-tech nyob rau hauv niaj hnub raug ntau hom alloys yog hlau, nrog rau lawv cov muaj pes tsawg leeg ntawm titanium ntsiab. Qhov no yog vim lub fact tias cov tau ua yuav luag tag biologically inert, thiab lub melting point ntawm steel raws li titanium - ib qho ntawm lub siab tshaj plaws.

Feem ntau cov steels muaj hlau nyob rau hauv nws muaj pes tsawg leeg raws li ib tug lub ntsiab tivthaiv. Qhov no yog vim tsis tau tsuas yog rau lub fact tias no hlau - ib qho ntawm feem ntau nyob rau hauv lub cheeb tsam, thiab qhov tseeb hais tias hlau yog zoo universal caij rau zus tau tej cov ntau yam qib ntawm hlau thiab alloys uas nws muaj. Qhov no qhov dav ntawm daim ntawv thov vim lub fact tias cov nqi ntawm melting kub ntawm cov hlau, sib npaug zos rau 1539 degrees, nyob rau hauv ua ke nrog nrog rau lwm cov cim tshuaj zog ua rau cov hlau tivthaiv haum rau ib tug ntau yam ntawm steel qib rau ntau lub hom phiaj.
