Vim txoj kev loj hlob tsis tu ncua ntawm nroog loj, cov khoom siv hauv cov khoom siv hauv tsev lag luam tau tshwm sim nyob rau qhov kawg. Txawm hais tias cov ntaub ntawv no feem ntau tshwm sim hauv peb lub neej niaj hnub, cov neeg uas feem ntau tsis khiav hauv cov khoom siv hauv tsev yuav tsis paub cov kav dej carbon steel. Peb yuav tsis nkag siab nws qhov zoo thiab qhov tsis zoo, thiab tej zaum yuav tsis quav ntsej nws lub neej. Tom ntej no, hnub no kuv yuav piav qhia rau koj seb cov khoom siv carbon steel yeeb nkab yog dab tsi? Dab tsi yog nws qhov zoo thiab qhov tsis zoo?

1) Cov khoom ntawm carbon steel yeeb nkab yog dab tsi?

Cov pa roj carbon steel feem ntau yog hais txog cov hlau uas nws cov khoom siv kho tshuab nyob ntawm cov ntsiab lus carbon hauv cov hlau. Feem ntau, ntau cov ntsiab lus alloying tsis ntxiv, thiab qee zaum hu ua cov pa roj carbon zoo tib yam lossis carbon hlau. Carbon steel, tseem hu ua carbon steel, hais txog cov hlau-carbon alloy nrog cov ntsiab lus carbon tsawg dua 2% WC. Ntxiv nrog rau carbon, carbon hlau feem ntau muaj me me ntawm silicon, manganese, sulfur, thiab phosphorus. Feem ntau, qhov siab dua cov ntsiab lus ntawm carbon steel, qhov hardness ntau dua, lub zog siab dua, tab sis cov yas qis dua.

Carbon steel yeeb nkab (cs yeeb nkab) yog ua los ntawm cov pa roj carbon steel ingots los yog cov khoom puag ncig steel los ntawm perforation rau hauv capillary hlab, thiab ces ua los ntawm kub dov, txias dov los yog txias txias. Cov yeeb nkab carbon steel plays lub luag haujlwm tseem ceeb hauv kuv lub teb chaws cov yeeb nkab steel kev lag luam.

2) Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm cov pa roj carbon steel kav?

Qhov zoo:

1. Cov pa roj carbon steel yeeb nkab tuaj yeem tau txais hardness dua thiab hnav zoo dua tom qab kev kho cua sov.
2. Lub hardness ntawm carbon steel yeeb nkab nyob rau hauv lub annealed lub xeev yog heev nruab nrab, thiab nws muaj zoo machinability.
3. Cov khoom siv raw ntawm cov yeeb nkab carbon steel yog ntau heev, yooj yim kom tau, thiab cov nqi tsim khoom kuj tsawg.

Qhov tsis zoo:

1. Qhov kub hardness ntawm carbon steel yeeb nkab yuav tsis zoo, vim hais tias thaum ua hauj lwm kub ntawm lub cuab tam yog siab tshaj 200 degrees, nws hardness thiab hnav kuj yuav poob sharply.
2. Lub hardenability ntawm carbon steel yog tsawg heev. Txoj kab uas hla ntawm cov hlau tsis muaj zog yog feem ntau txog 15-18 hli thaum dej quenched, thaum txoj kab uas hla lossis tuab ntawm cov hlau tsuas yog li 6 hli thaum nws tsis quenched, yog li nws yuav yooj yim rau deform thiab tawg.

3) Kev faib tawm ntawm cov khoom siv carbon steel yog dab tsi?

1. Raws li daim ntawv thov, cov pa roj carbon steel tuaj yeem muab faib ua peb pawg: carbon steel hlau, carbon cuab yeej steel thiab dawb-txiav cov qauv hlau.
2. Raws li txoj kev smelting, carbon steel yuav muab faib ua peb pawg: qhib hearth rauv steel, converter steel thiab hluav taws xob rauv hlau.
3. Raws li cov txheej txheem deoxidation, carbon hlau tuaj yeem muab faib ua cov hlau npau npau, tua steel, semi-tua steel thiab tshwj xeeb tua hlau, uas yog sawv cev los ntawm cov lej F, Z, b, thiab TZ raws.
4. Raws li cov ntsiab lus carbon, carbon hlau tuaj yeem muab faib ua peb pawg: carbon steel qis, nruab nrab carbon steel thiab siab carbon steel.
5. Raws li cov ntsiab lus ntawm leej faj thiab phosphorus, carbon hlau tuaj yeem muab faib ua cov pa roj carbon zoo tib yam (cov ntsiab lus ntawm phosphorus thiab sulfur yuav siab dua), cov pa roj carbon zoo (cov ntsiab lus ntawm phosphorus thiab sulfur yuav qis dua), siab. -zoo hlau (muaj phosphorus thiab sulfur tsawg cov ntsiab lus) thiab super high-zoo hlau.

4) Dab tsi yog kev faib tawm ntawm carbon steel kav?

Carbon steel kav yuav muab faib ua seamless kav, ncaj seam steel kav, kauv kav, high zaus welded steel kav, thiab lwm yam.

Kub dov seamless steel yeeb nkab (extruded): round tube billet → cua sov → tho → peb-yob cross dov, nruam dov los yog extrusion → stripping → sizing (los yog txo) → txias → straightening → hydraulic test (los yog Flaw detection) → marking → khaws cia

Cold drawn (dov) carbon steel seamless steel yeeb nkab: round tube blank → cua sov → tho → taub hau → annealing → pickling → oiling (tooj liab plating) → multi-pass txias drawing (txias dov) → blank raj → tshav kub kho → straightening → Hydrostatic kuaj (kev kuaj pom qhov tsis haum) → Mark → Cia

Cov pa roj carbon steel seamless steel kav tau muab faib ua ob hom: kub dov (extruded) seamless steel kav thiab txias-draw (dov) seamless steel kav vim lawv cov txheej txheem tsim khoom sib txawv. Cold drawn (dov) raj tau muab faib ua ob hom: cov raj puag ncig thiab cov raj tshwj xeeb.
