carbon steel phaj

Yam khoom yog dab tsicarbon steel phaj?
Nws yog hom hlau uas muaj cov ntsiab lus carbon tsawg dua 2.11% thiab tsis txhob txwm tshaj tawm cov ntsiab lus hlau.Nws tuaj yeem hu ua cov pa roj carbon zoo tib yam lossis cov hlau tsis zoo.Ntxiv nrog rau cov pa roj carbon monoxide, kuj tseem muaj me me ntawm silicon, manganese, sulfur, phosphorus thiab lwm yam khoom hauv.Qhov siab dua cov ntsiab lus carbon, qhov zoo dua qhov hardness thiab lub zog, tab sis cov yas yuav phem dua.
Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm carbon steel phaj
Qhov zoo ntawm carbon steel phaj yog:
1. Tom qab kev kho cua sov, qhov hardness thiab hnav tsis kam tuaj yeem txhim kho.
2. Lub hardness yog tsim nyog thaum lub sij hawm annealing, thiab lub machinability yog zoo.
3. Nws cov khoom siv raw yog ntau heev, yog li nws yooj yim mus nrhiav, yog li tus nqi tsim khoom tsis siab.
Qhov tsis zoo ntawm carbon steel phaj yog:
1. Nws thermal hardness tsis zoo.Thaum nws siv los ua riam hauv nroog cov khoom, qhov nyuaj thiab hnav tsis kam yuav ua phem dua thaum kub tshaj 20 degrees.
2. Nws hardenability tsis zoo.Txoj kab uas hla feem ntau yog khaws cia ntawm 15 mus rau 18 hli thaum dej quenched, thaum txoj kab uas hla thiab thickness thaum nws tsis quenched yog feem ntau 6 hli, yog li nws yog feem ntau deformation los yog tawg.
Carbon steel cais los ntawm cov ntsiab lus carbon
Cov pa roj carbon steel tuaj yeem muab faib ua peb pawg: carbon steel tsawg, nruab nrab carbon steel thiab siab carbon steel.
Mild Steel: Feem ntau muaj 0.04% rau 0.30% carbon.Nws los ntawm ntau yam duab thiab cov ntsiab lus ntxiv tuaj yeem ntxiv nyob ntawm seb cov khoom xav tau.
Medium Carbon Steel: Feem ntau muaj 0.31% rau 0.60% carbon.Cov ntsiab lus ntawm manganese yog 0.060% txog 1.65%.Cov pa roj carbon steel nruab nrab muaj zog dua thiab nyuaj rau tsim dua li cov hlau me me.Vuam thiab txiav.Nruab nrab carbon steel feem ntau quenched thiab tempered los ntawm kev kho cua sov.
High carbon steel: feem ntau hu ua "carbon tool steel", nws cov ntsiab lus carbon feem ntau yog nyob nruab nrab ntawm 0.61% thiab 1.50%.High carbon steel yog nyuaj rau txiav, khoov thiab vuam.

Cov pa roj carbon steel yog qhov ntxov tshaj plaws thiab feem ntau siv cov khoom siv hauv kev lag luam niaj hnub no.Thaum siv zog ua kom cov khoom siv qis-alloy high-strength steel thiab alloy steel, muaj lub teb chaws nyob hauv lub ntiaj teb no kuj tau xyuam xim rau kev txhim kho cov pa roj carbon steel zoo thiab nthuav dav ntau yam thiab kev siv..Tshwj xeeb tshaj yog txij li xyoo 1950, cov thev naus laus zis tshiab xws li oxygen converter steelmaking, kev txhaj tshuaj tawm ntawm lub cub tawg, nruam steel casting thiab nruam dov tau siv dav, ntxiv kev txhim kho cov pa roj carbon zoo thiab nthuav dav ntawm kev siv.Tam sim no, qhov feem pua ​​​​ntawm cov pa roj carbon steel tso tawm hauv tag nrho cov khoom siv hlau ntawm ntau lub teb chaws tseem nyob ntawm 80%.Nws tsis yog tsuas yog siv dav hauv kev tsim kho, txuas hniav, kev tsheb ciav hlau, tsheb, nkoj thiab ntau yam kev lag luam kev lag luam, tab sis kuj tseem nyob hauv kev lag luam petrochemical niaj hnub.﹑ Marine kev loj hlob thiab lwm yam, kuj tau siv dav.

Qhov txawv ntawmtxias dov steel phajthiabkub dov steel phaj:

1. Cold-rolled steel tso cai rau hauv zos buckling ntawm seem, kom cov bearings muaj peev xwm ntawm cov tswv cuab tom qab buckling yuav siv tau tag nrho;thaum kub-dov hlau tsis tso cai rau hauv zos buckling ntawm seem.

2. Yog vim li cas rau qhov seem ntawm kev ntxhov siab ntawm cov hlau kub-kuav los tiag thiab txias-kuav los tiag steel yog sib txawv, yog li qhov kev faib tawm ntawm cov ntoo khaub lig-section kuj txawv heev.Qhov seem ntawm kev ntxhov siab nyob rau hauv seem ntawm cov txheej txheem txias-tsim nyias-walled steel yog nkhaus, thaum seem kev ntxhov siab faib rau ntawm ntu ntu ntawm kub-kuav los yog welded steel yog nyias-zaj duab xis.

3. Qhov dawb torsional nruj ntawm cov kub dov seem steel yog siab dua li ntawm cov khoom txias-kuav los tiag steel, yog li qhov torsional tsis kam ntawm kub dov seem steel yog zoo dua li ntawm txias-kuav los tiag seem steel.Kev ua tau zoo muaj kev cuam tshuam loj.

Lub dov ntawm cov hlau yog tsuas yog ua raws li kub dov, thiab txias dov tsuas yog siv los tsim cov hlau me me thiab cov ntawv.
