Hlau VS Hlau: ib qho kev sib piv ntawm cov khoom
Hlau thiab cov hlau yog ob ntawm cov feem ntau siv cov hlau hauv ntiaj teb, nrog txhua tus muaj cov khoom sib txawv uas ua rau lawv haum rau cov ntawv thov sib txawv. Thaum lawv qhia qee yam sib xws, qhov sib txawv tseem ceeb ntawm lawv yog rooted hauv lawv cov lus thiab txoj kev uas lawv sib cuam tshuam nrog lwm cov ntsiab lus. Hauv tsab xov xwm no, peb yuav sib piv cov khoom ntawm hlau thiab hlau kom nkag siab zoo dua li lawv txawv li cas lawv yuav nyiam dua lwm cov kev siv.
1. Muaj pes tsawg leeg
Liv: Cov hlau ntshiab, nrog cov tshuaj lom neeg cim FE, yog lub ntsiab muag yog xim hlau uas yog ib txwm muaj tshwm sim. Nws yog feem ntau ua los ntawm cov hlau atoms thiab feem ntau pom nyob rau hauv cov ores zoo li hematite thiab magnetite. Cov hlau ntshiab yog tus mos mos kuj mos thiab muaj lub zog qis tensile.
Hlau: Hlau yog ib qho alloy ntawm cov hlau uas feem ntau muaj cov pa roj carbon uas yog qhov me me ntawm lwm cov khoom xws li manganese, npib chromium, thiab Vanadium. Qhov sib ntxiv ntawm carbon (feem ntau nruab nrab ntawm 0. 02% rau 2.1% ntxiv ulertical ntawm hlau, txhim kho nws lub zog, tawv ncauj, thiab lwm yam khoom siv mechanical, thiab lwm yam khoom siv mechanical.
2. Lub zog thiab durability
Liv: Ntshiab hlau yog tus kuj mos muag piv rau cov hlau. Nws muaj lub zog tensile, uas txhais tau tias nws tsis tuaj yeem tiv thaiv ntau dua lossis ncab lub zog ua ntej tawg. Qhov no ua rau cov hlau ntshiab tsis haum rau cov kev thov uas feem ntau ntawm nws tus kheej.
Hlau: Steel, vim yog cov ntsiab lus carbon thiab cov khoom siv alloy, muaj zog dua thiab nyuaj dua li cov hlau ntshiab. Cov pa roj carbon hauv cov hlau ua cov ntawv hlau carbide, uas txhim kho nws lub hardness. Cov hlau tuaj yeem ntxiv dag zog los ntawm cov txheej txheem kho cua sov xws li tempering, ua rau nws zoo tagnrho rau ntau yam kev lag luam siv, los ntawm kev tsim kho rau kev tsim kho tsheb.
3. Corrosion Kuj
Liv: Hlau yog heev nquag mus rau corrosion thaum raug rau noo noo thiab oxygen, tsim cov hlau oxide lossis xeb oxide lossis xeb. Cov txheej txheem xeb tsis muaj zog cov hlau thiab degrades nws kev ua tau zoo dhau sijhawm.
Hlau: Hlau tiv thaiv kom corrosion txawv nyob ntawm nws cov muaj pes tsawg leeg. Carbon Steel, piv txwv li, tuaj yeem corrode, tuaj yeem zoo li hlau ntshiab. Txawm li cas los xij, alloy steels xws li stainless hlau, uas muaj chromium, yog siab tiv taus corrosion. Stainless hlau ua cov txheej txheem tiv thaiv oxide txheej rau ntawm nws cov npoo, uas tiv thaiv xeb thiab txhim kho nws qhov kev ua haujlwm tsis tu ncua nyob hauv ib puag ncig hnyav.
4. Kev ua haujlwm
Liv: Ntshiab hlau yooj yim rau kev ua haujlwm nrog vim nws lub mos muag. Nws tuaj yeem ua tau zoo li, hammered, thiab forged yam tsis xav tau kev quab yuam ntau dhau, ua rau nws tsim cov khoom xws li cov cuab yeej lossis cov cuab yeej yooj yim. Txawm li cas los xij, nws lub zog qis txwv nws siv nyob rau hauv cov ntawv thov ntau dua.
Hlau: Steel kuj tseem ua haujlwm tau yooj yim tab sis yuav tsum tau siv zog ntau dua rau cov duab kom haum rau cov hlau ntshiab vim nws hardness. Cov hlau tuaj yeem welded, forged, thiab machined, tab sis theem ntawm kev ua haujlwm yog nyob ntawm hom hlau. Piv txwv li, cov hlau me (cov hlau tsis muaj roj) tau yooj yim dua ua haujlwm nrog ntau dua cov hlau hluav taws xob, uas yog nkig ntau.
5. Qiv thiab mallability
Liv: Cov hlau ntshiab yog cleatile (nws tuaj yeem ua kom ncav tau mus rau hauv ib lub xaim) thiab malleable rau hauv cov nplooj ntawv nyias), tab sis nws tsis muaj cov hlau nyuaj thiab yooj yim ntawm cov hlau. Raws li qhov tshwm sim, cov hlau ntshiab yog cov muaj peev xwm ua kom muaj txiaj ntsig lossis tawg rau hauv kev ntxhov siab.
Hlau: Steel feem ntau tsawg dua ductile dua li cov hlau ntshiab, tshwj xeeb tshaj yog cov pa roj carbon hlau. Txawm li cas los xij, kev ducility thiab kev ua haujlwm ntawm cov hlau tuaj yeem tswj tau los ntawm kev kho cov ntsiab lus carbon thiab alloy. Piv txwv li cov hlau me me yog cov ductile thiab malleable, ua rau nws haum rau cov ntawv thov uas xav tau kev siv tsheb thiab kev lag luam kev lag luam.
6. Tus nqi thiab muaj
Liv: Ntshiab hlau yog cov pheej yig los tsim thiab muaj ntau nyob hauv lub ntiaj teb crust. Txawm li cas los xij, nws cov khoom siv tsawg dua ua rau nws tsis zoo rau cov ntawv thov niaj hnub no, yog li txo nws cov kev xav tau tag nrho.
Hlau: Steel yog kim dua li cov hlau ntshiab vim yog cov nqi ntxiv ntawm kev siv alloy thiab kev ua. Ntau yam ntawm cov hlau muaj (carbon hlau, hlau steel, allloy steel, thiab lwm yam) txhais tau tias cov hlau tuaj yeem ua rau aerospace, ua rau muaj ntau yam khoom siv thiab dav siv.
7. Kev thov
Liv: Cov hlau ntshiab tau txwv nyob rau hauv cov ntawv thov niaj hnub vim nws qhov muag muag thiab ntxim nyiam rau kev xeb. Txawm li cas los xij, nws tseem siv nyob rau qee cov ntawv thov tshwj xeeb xws li cov khoom siv hluav taws xob (hauv nws daim ntawv purest) thiab ua cov khoom siv ua kom tau siv rau hauv cov tshuab, cov khoom lag luam, thiab lwm yam khoom lag luam.
Hlau: Steel siv nyob rau hauv cov ntawv thov suav tsis tau vim nws lub zog zoo dua, tawv tawv, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility. Nws yog siv nyob rau hauv kev tsim kho ntawm cov tsev, choj, nkoj, thiab tsheb, thiab kev ua lag luam xws li Machinery, thiab khoom siv khoom siv. Cov hlau tshwj xeeb, xws li stainless hlau, yog siv rau hauv cov ntawv thov uas yog qhov tseem ceeb, zoo li hauv kev lag luam khoom noj, thiab ib puag ncig kho mob.
8. Kev kho cua sov
Liv: Cov hlau ntshiab muaj qhov tsawg dua ntawm 1538 degree f), tab sis nws tsis tau txais txiaj ntsig ntau ntawm kev txhim kho nws cov khoom siv tshuab, raws li nws tsis tshua mos.
Hlau: Steel tuaj yeem ua tau kub ua rau muaj ntau txoj hauv kev los txhim kho nws lub hardness, lub zog, thiab lwm yam khoom. Kev kho kho kom sov xws li quenching, Tempering, thiab annealing, thiab kev tso cai tswj kom meej, ua rau nws tsim nyog siv rau ntau yam qauv hlau los ua cov cuab yeej hlau.
9. Kev cuam tshuam ib puag ncig
Liv: Kev rho tawm thiab kev ua cov hlau tuaj yeem muaj qhov cuam tshuam tseem ceeb ib puag ncig, suav nrog kev rhuav tshem ib puag ncig tseem ceeb, suav nrog kev rhuav tshem, kev puas tsuaj, thiab ua qias tuaj. Txawm li cas los xij, hlau nws tus kheej yog 100% siv dua tshiab thiab tuaj yeem siv tau siv hauv ntau hom ntawv.
Hlau: Steel ntau lawm siv lub zog-ua kom muaj zog, tab sis zoo li hlau, nws yog siv tau yooj yim. Qhov tseeb, cov hlau ub hlau yuav tsum muaj lub zog tsawg dua li ua cov hlau tshiab los ntawm cov khoom siv raw. Cov hlau kev lag luam ua haujlwm rau kev txo nws txoj kev ib puag ncig los ntawm kev siv hluav taws xob muaj zog thiab siv ntau dua ntawm cov hlau rov ua haujlwm.
Xaus: Qhov sib txawv ntawm cov hlau thiab hlau
Thaum ob qho tib si hlau thiab hlau yog cov ntaub ntawv tseem ceeb hauv ntiaj teb niaj hnub, lawv cov khoom sib txawv. Hlau yog mos, nquag mus rau corrosion, thiab txwv nyob rau hauv nws cov ntawv thov vim nws tsis muaj lub zog thiab kav ntev. Hlau, ntawm qhov tod tes, muaj zog dua, ntau ntau yam ntxiv, thiab tuaj yeem ua kom cov ntawv thov tshwj xeeb los ntawm kev sib ntxiv thiab kev kho kom sov.
Hlau txhim kho cov khoom ua rau nws cov khoom siv ntawm kev xaiv rau feem ntau cov ntawv thov kev lag luam, los ntawm kev tsim kho kom raug. Txawm li cas los xij, hlau tseem ua lub luag hauj lwm tseem ceeb hauv kev tsim cov hlau pov thiab qee yam tshwj xeeb.
Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm cov hlau thiab cov hlau dag hauv lawv cov muaj pes tsawg leeg, muaj zog, nrog rau cov hlau ua kom muaj zog dua thiab cov kav ntev rau cov ntawv thov dav.
