2024 Tus sau: Howard Calhoun | [email protected]. Kawg hloov kho: 2023-12-17 10:28

Hnub no, kev lag luam dov hlau tau loj hlob ntau heev uas nyob rau hauv nws txoj kev sib txawv ib tus neeg tsis tau npaj tau yooj yim tuaj yeem poob thiab, vim li ntawd, tsis xaiv qhov nws xav tau thaum pib. Nws yog qhov ua tau kom tsis txhob muaj qhov sib xyaw ua ke ntawm qhov xwm txheej. Txhawm rau ua qhov no, koj yuav tsum tsis tu ncua thiab ntev txaus los kawm cov ntaub ntawv ntsig txog, GOSTs thiab lwm yam ntaub ntawv. Txawm li cas los xij, muaj txoj hauv kev yooj yim dua - hauv kab lus no koj yuav tau paub txog cov ntaub ntawv tseem ceeb tshaj plaws thiab tsim nyog txog steel 15HSND, txiav txim siab nws cov npe, daim ntawv thov, muaj pes tsawg leeg, thiab txawm tias hloov hom. Cov ntaub ntawv thov yuav cawm tau txawm tias tus neeg tsis tau npaj siab tshaj plaws los ntawm kev mob siab ntev thiab tsis txaus ntseeg ntawm cov ntaub ntawv kev tshaj lij.

Kev txiav txim lub npe ntawm steel

Rau ib tus neeg tsis tau npaj txhij, cov lus "steel 15HSND" feem ntau yuav zoo li lub ntsej muag khawv koob lossis tsuas yog qhov tsis sib xws, tab sis leej twg tau ntsib metallurgy, txawm tias tsis ncaj, yuav nkag siab tam sim ntawd ib yam dab tsi zais tom qab. cov ntawv thiab cov lej no tseem ceeb dua. Nws yog nrog cov ntawv nocov kws tshaj lij paub txog cov khoom thiab kwv yees li ntawm cov hlau. Yog li lawv ua li cas? Qhov tseeb, txhua yam yog yooj yim:

• Tus lej 15 ua ke nrog tsab ntawv "X" qhia cov ntsiab lus ntawm 0.15% chromium hauv cov hlau.
• Tsab ntawv "C" nyob rau hauv cov khoom siv hlau hauv tsev qhia txog cov tshuaj lom neeg silicon.
• Tsab ntawv "H" qhia meej cov ntsiab lus ntawm nickel hauv cov hlau.
• Tsab ntawv "D" txhais tau hais tias lub ntsiab lus ntawm lub rooj zaum ua tooj liab.
• Thiab txij li tsuas yog chromium muaj tus lej tsim, qhov feem pua raug ncua ntawm tag nrho cov ntsiab lus tom ntej qhia hauv lub npe tsis tseem ceeb.

Daim ntawv thov

Txhua tus neeg qib steel ib txwm muaj nws tus kheej lub xeev tus qauv, lossis GOST, uas tswj hwm txhua yam ntaub ntawv cuam tshuam txog qib steel no. 15HSND, tau kawg, tsis muaj kev zam. Cov npe hauv qab no tau muab rau nws nyob rau hauv GOST sib xws: "tsawg-alloy structural steel rau siv nyob rau hauv welded hlau lug lossis chromium-silicon-nickel steel."

Feem ntau cov hom no yog tsim nyob rau hauv cov ntawv hlau, uas txiav txim siab nws ntxiv siv nyob rau hauv ntau yam lag luam.

Kom meej meej, 15KhSND steel yog muab rau cov lag luam feem ntau cuam tshuam nrog kev tsim cov qauv ua ntej. Piv txwv li, nws yog siv nyob rau hauv choj tsev, mechanical engineering, kev tsim kho thiab ntau lwm yam lag luam, uas qhia tau hais tias ib co muaj koob meej.qib steel no.

Steel composition

Qhov kev txiav txim siab uas muab cov khoom siv hlau yog nws cov muaj pes tsawg leeg. Los ntawm cov tshuaj dab tsi uas muaj nyob rau hauv cov muaj pes tsawg leeg ntawm cov alloy, nws ncaj qha nyob ntawm seb nws puas yuav ua tau ruaj khov, dab tsi ib puag ncig tej yam kev mob nws muaj peev xwm tiv taus, dab tsi sab hauv nws yuav muaj, thiab ntau ntxiv. Tsis tas li qhov tseem ceeb yog qhov feem pua ntawm ib lossis lwm lub ntsiab lus, vim tias nws nyob ntawm seb cov khoom muaj zog npaum li cas uas tib lub ntsiab lus los ntawm lub sijhawm ua haujlwm yog lub luag haujlwm.

Rau steel 15KhSND cov tshuaj muaj pes tsawg leeg hauv qab no yog ib txwm:

• carbon - 0.15%;
• silicon - 0.55%;
• manganese - 0.55%;
• chrome - 0.75%;
• nickel - 0.45%;
• copper - 0.3%;
• nitrogen - 0.012%;
• sulfur - 0.04%;
• phosphorus - 0.035%;
• arsenic - 0.08%;

yam ntxwv

Raws li koj tuaj yeem pom, cov npe ntawm cov ntsiab lus yog qhov dav heev, tab sis feem pua ntawm txhua tus neeg sawv cev tsawg heev, yog li lawv tsis muab qhov tseem ceeb ntawm cov yam ntxwv ntawm lub zog ntawm 15KhSND steel, tab sis lawv txhim kho cov qauv zoo., tiv thaiv cov hlau los ntawm ntau yam kev puas tsuaj sab hauv, yog nws tawg, micropores, pab pawg, kab noj hniav, thiab tseem muaj txiaj ntsig zoo rau nws qhov zoo tag nrho, thiab muab cov ntsiab lus tsis tshua muaj txiaj ntsig zoo, xws li cov hlau yuav muaj txiaj ntsig ntau dua. ntawm tus nqi / zoo piv.

Kev hloov pauv

Yog tias koj tshawb nrhiav zoo, ces txhua yam khoom lag luam hauv khw yuav muaj cov neeg sib tw uas yuav luag tag nrho cov khoom qub lossis tseem dhau ntawm qee txoj kev. Ib txoj cai zoo sib xws siv rau metallurgy, qhov twg rau txhua qib steel muaj tsawg kawg yog ib lossis ob peb lub npe los ntawm qeb ntawm "hloov", uas yog, cov ntaub ntawv zoo sib xws hauv cov khoom thiab muaj pes tsawg leeg.

Rau 15KhSND steel ntawm kev lag luam hauv tsev, cov nram qab no tuaj yeem sib txawv:

• 16G2AF - steel nrog me ntsis loj ntawm silicon nyob rau hauv muaj pes tsawg leeg, nrog rau ntxiv ntawm vanadium, uas txhim kho nws lub zog yam ntxwv.
• 15GF - yuav luag zoo ib yam li qhov kev xaiv dhau los, tshwj tsis yog qhov feem pua ntawm cov ntsiab lus me me hauv cov ntsiab lus.
• 14HGS yog ib qho pheej yig dua, tab sis tsis muaj qhov sib npaug sib npaug haum rau cov qauv me me.
• 16GS - feem ntau, qhov no yog qhov zoo heev, txawm hais tias qee qhov tsis tiav, analogue ntawm 15HSND, haum rau cov qauv uas raug rau cov khoom nruab nrab zoo li qub.

Txawm li cas los xij, yog tias koj muaj kev ua haujlwm ua ntej ntawm koj qhov chaw uas koj yuav tsum tau siv cov hlau rau kev tsim kho ntawm qee yam qauv lossis cladding, nws yog qhov zoo dua tsis txhob muag pheej yig thiab yuav cov qib steel zoo tshaj plaws.
