Cov hlau alloy dav siv hauv kev lag luam thiab kev tsim kho vaj tse, lossis carbon, yog qhov tshwm sim ntawm kev sib xyaw ntawm ob lub ntsiab lus: hlau thiab carbon. Cov khoom siv no yog siv rau hauv kev tsim kho tsheb, tshuab ntxhua khaub ncaws, kho kom zoo nkauj ntawm ib puag ncig thiab ntau lwm yam kev siv. Nkag siab txog nws cov khoom thiab nws qhov kev siv tau yog qhov tseem ceeb rau kev txiav txim siab yuav khoom!
O aço carbon possui um custo acessível, muab ntau hom kev siv thiab kev tawm tsam. Nrog rau qhov ntxhib tiav, cov qauv no yog qhov nrov heev thiab siv tau heev, thaum nws muaj cov khoom siv kho tshuab uas sib txawv raws li cov khoom siv thiab nws cov khoom sib xyaw.
Yog tias koj xav paub ntau ntxiv txog cov pa roj carbon steel, lawv qhov kev siv tau thiab cov hom tseem ceeb siv hauv kev lag luam, xyuas cov ntawv no!
Los yog Aço Carbono yog dab tsi?
Nws cov pa roj carbon monoxide yog ib qho hlau alloy, thiab nws cov kev cai hlau alloy confers nws theem ntawm txhua yam tsis kam, muaj 0.008 feem pua rau 2.11 feem pua ntawm cov pa roj carbon concentration hauv nws cov muaj pes tsawg leeg. Cov hlau gusa, tam sim no cov khoom ntawm kev txo cov hlau ore mining coke los yog carvão thiab calcário ntawm qhov kub thiab txias, yog lub hauv paus siv los tsa ntau hom aço.
Hom carbon aço
Muaj ntau yam khoom uas lav qhov tsim nyog hardness. O carbon yog lub ntsiab hardening. Manganese, silicon thiab phosphorous kuj tswj cov qib ntawm cov kua qaub. Cov pa roj carbon ntau txhais nws cov kev faib tawm hauv: qis, nruab nrab thiab siab. Muaj 3 hom carbon dioxide, txhua tus muaj nws tus yam ntxwv thiab kev siv. Paub meej:
Tsawg carbon (ntawm 0, 30 feem pua ntawm carbon)
Cov pa roj carbon steel hom no muaj qhov tsis zoo, yog li nws yog usinável thiab weldable. Muaj tsawg hardness thiab siab toughness thiab ductility. Feem ntau, nws tsis yog cua sov kho.
Cov pa roj carbon nruab nrab (los ntawm {{0}}, 30 feem pua rau 0.60 feem pua)
Muaj kev tiv thaiv siab dua rau kev kho cua sov, ntxiv rau qhov hardness thiab qis toughness thiab ductility ntawm cov pa roj carbon tsawg. Qhov nruab nrab carbon possui kub zoo nyob rau hauv dej thiab nws yog ib qho ntawm ob hom ntawm aço.
Cov pa roj carbon ntau (siab dua 0,60 feem pua)
Hom no muaj kev tiv thaiv ntau dua rau kev hnav thiab hardness. Tsis ntau, los yog siab carbon possui qis ductility thaum piv rau lwm tus. Feem ntau, lawv yog siv tempered los yog tempered, muaj kev txij nkawm ntawm kev txiav ntug.
Puas yog carbon ferruja?
Nyob rau hauv kev sib piv rau stainless hlau, los yog carbon, lawv muaj tsawg tsis kam mus corrosion. Txawm li cas los xij, nyob ntawm qhov concentration ntawm cov pa roj carbon monoxide, kev tiv thaiv oxidation nce. Ntawm lwm cov kev siv sib txawv, cov pa roj carbon steel raj tau dav siv hauv cov qauv ntawm cov chaw nres nkoj thiab cov superheaters.
Cov kev siv tseem ceeb ntawm carbon steel:
Kev lag luam thiab kev lag luam siv;
Daim hlau rau kev tsim cov raj steel;
kev tsim kho pej xeem;
Rhodes thiab railway khoom;
Iav rau lub tshuab qhov chaw uas yuav tsum tau muaj kev ua haujlwm siab;
Raw khoom rau architectural tej hauj lwm thiab niaj hnub kos duab;
Cov khoom siv gym;
Brinquedos;
Corrimões de escadas;
Cov dej ntws;
Hlau qauv, sawv ntsug, usinagens thiab serralheria;
Cov khoom siv hauv tsev kho mob.
Kev faib tawm ntawm ob lub xyoo carbon
Cov txheej txheem kev faib tawm feem ntau siv hauv kev xyaum yog SAE-AISI, tsis yog ib qho uas siv cov pa roj carbon lossis pab pawg 1xxx, cais raws li:
10xx: Common carbon hlau
11 xx: Resulfurized
12xx: Resulfurized thiab Rephosphorated
13xx: Contém txog 1.75 feem pua ntawm Manganês
14xx: Muaj cov concentration ntawm Niobium
15xx: Carbon steel nrog siab Manganês txoj kev xav
Nco tseg: carbon dioxide uas yuav tsum muaj qhov kub thiab txias ntxiv yuav muaj "H" ntxiv rau kev faib tawm. Lub "xx" sawv cev rau qhov concentration ntawm cov tsis yog-acid carbon. Piv txwv li: O aço 1030 possui kwv yees li 0.30 feem pua ntawm cov pa roj carbon nyob rau hauv nws cov muaj pes tsawg leeg.
Khoom:
txheeb ze hardness;
Kev tawm tsam nce raws li Carbon txoj kev xav;
Diminui ductility raws li Carbon txoj kev xav;
Tiv thaiv qhov kub thiab txias;
Nws tuaj yeem siv rau hauv kev teeb tsa hluav taws xob.
Cov txiaj ntsig:
Tus nqi zoo tshaj / txiaj ntsig;
Kev siv sib txawv;
Siab tsis kam;
High durability;
Versatility;
qis fusion point;
Siab weldability.
Cov pa roj carbon steel raj tuaj yeem pom nyob rau hauv cov qauv sib txawv thiab cov qauv, thiab tau thov zoo tshaj plaws rau cov neeg uas xav nqis peev hauv kev nyab xeeb thiab kev tiv thaiv. Tam sim no koj nkag siab qhov teeb meem, ib tug hais tias: tsis hais txog qhov siv tau, los nqis peev hauv cov khoom ntawm ib txwm nyiam rau cov tuam txhab ntseeg siab, uas ua lag luam 100 feem pua cov khoom pov thawj pov thawj originality, keeb kwm, tsis kam thiab qauv tsim!
