Ntau haiv neeg hauv kev lag luam steel feem ntau hem cov neeg uas, vim li cas los yog lwm qhov, yuav tsum xaiv thiab yuav cov qib tshwj xeeb ntawm cov hlau rau cov kev xav tau tshwj xeeb. Ib tus neeg uas tsis tau npaj txhij nrog qhov muaj peev xwm ua tau zoo yuav poob rau hauv qhov kev sib txawv no thiab yuav tsis xaiv dab tsi thaum kawg. Qhov teeb meem no tau daws los ntawm kev tshawb fawb ntev thiab siv lub ntsiab lus, nkag siab txog nws qhov tseem ceeb, ntau qhov kev sib tham thiab ntau ntxiv. Txawm li cas los xij, muaj ib txoj hauv kev los txiav luv luv.

ВPeb tau sim sau rau koj cov ntaub ntawv tseem ceeb tshaj plaws thiab muaj txiaj ntsig ntsig txog steel 09G2S. Kev nyeem ntawv yuav tsis siv sij hawm ntau, thiab cov kev paub uas tau txais yuav pab koj xaiv cov khoom tsim nyog.

Steel 09G2S - transcript

txhawm rau nkag siab tias cov khoom siv hlau muaj dab tsi, nws tsis yog qhov tsim nyog los kawm nws cov qauv molecular uas siv cov cuab yeej kuaj sim. Feem ntau, kom tau txais lub tswv yim dav dav ntawm cov khoomhlau thiab nws lub hom phiaj, nws yog txaus kom decipher lub npe ntawm steel qib. 09G2S nyob rau hauv cov ntaub ntawv no yog decrypted raws li nram no algorithm:

• Tus lej tus nqi 09 sib raug rau cov ntsiab lus carbon hauv cov ntsiab lus ntawm cov hlau. Feem ntau, tus nqi siab tshaj plaws tau qhia, uas txhais tau hais tias qhov feem pua raug tshem tawm ntawm cov khoom no hauv ib chav tsev ntawm cov hlau tsis tshaj qhov pib ntawm 0.9%.
• tsab ntawv "G", raws li Soviet GOST system, qhia txog cov ntsiab lus ntawm xws li cov khoom alloying li manganese.
• Tus lej tom ntej "2" qhia qhov siab tshaj plaws ntawm cov ntsiab lus ntawm cov khoom no, sib npaug li ob feem pua ntawm tag nrho cov huab hwm coj.
• Tsab ntawv "C" hauv Soviet GOST system sib raug rau silicon. Xav tias tsis muaj tus lej ntxiv, nws cov ntsiab lus yog, qhov nruab nrab, tsawg dua ib feem pua.

Steel composition

Yuav kom kawm txog cov khoom ntawm cov hlau no kom ntxaws, nws yuav tsum paub nws zoo dua me ntsis. Ua li no, muaj cov ntaub ntawv tshwj xeeb kev tswj hwm ntawm lub xeev tus qauv, hauv lwm lo lus - GOSTs. Steel 09G2S, raws li nws cov qauv zoo, muaj cov hauv qab no:

• Carbon (txog 0.12%) yog ib qho tseem ceeb tshaj plaws additives uas muab steel qhov tsim nyog hardness thiab lub zog, tab sis, vim li ntawd, brittleness.
• Silicon (0.65%) - lub ntsiab lus uas cuam tshuam rau cov cua sov ntawm cov hlau.
• Manganese (1.5%) - ib qho ntxiv uas ua rau kom muaj zog ntawm cov hlau thiab nws cov hardenability.
• Nickel (txog 0.3%). Cov khoom no nyob rau hauv lub composition sib raugtxhawm rau ua kom cov ductility ntawm cov hlau tsis txo qis nws lub zog zog.
• Sulfur (txog 0.04%) yog ib qho teeb meem impurity uas ua rau lub zog ntawm cov hlau tsis zoo, tab sis nws cov feem pua yog qhov tsis tseem ceeb, uas txhais tau hais tias cov nyhuv ntawm cov khoom tsis tseem ceeb.
• Phosphorus (txog 0.035%) - cov khoom zoo ib yam li sulfur, muaj qhov cuam tshuam loj dua, yog li nws cov ntsiab lus tau tswj hwm tshwj xeeb yog ua tib zoo.
• Chromium (txog 0.3%) ua kom cov hlau tsis kam oxidation thiab xeb.
• Nitrogen (txog 0.008%) yog ib qho kev tsis huv uas tshwm sim los ntawm cov txheej txheem steelmaking.
• tooj liab (txog 0.3%) muaj txiaj ntsig zoo ntawm cov hlau ductility.
• Arsenic (txog 0.08%) yog lwm qhov tsis zoo uas tsis zoo uas ua rau cov tsos mob ntawm sab hauv, tab sis nws cov ntsiab lus txwv.

yam ntxwv ntawm steel 09G2S

Cov hauv qab no yog qhov pom tau zoo heev: muaj ntau cov impurities hauv cov hlau. Kaum hom alloying ntsiab yog ib qho tseem ceeb, tab sis tsuas yog manganese tuaj yeem khav ntawm cov ntsiab lus tseem ceeb. Raws li qhov no, nws tuaj yeem ntseeg tau tias 09G2S steel muaj cov khoom siv hluav taws xob, thiab cov khoom tsis huv tsuas yog ntxiv thiab txhim kho cov qauv hlau, uas muaj txiaj ntsig zoo rau nws cov khoom siv lub cev. Nws tseem yog yas, yooj yim amenable rau lub cev ua, nrog rau kev tig. Hlau, ntawm lwm yam, muaj ib tug heev homogeneous qauv, uas tso cai rau nws tiv taus siab loads thiab pressures.

Analogues

Cov qib steel zoo sib xws tuaj thoob plaws txhua qhov chaw. Qhov no yog vim lawv qhov kev thov tas li. Nws yog feem ntau yuav tsum tau yuav ib feem ua los ntawm steel 09G2S. Yog li ntawd, nws yuav zoo rau muaj nyob ntawm tes ib daim ntawv teev npe ntawm nws cov neeg txawv teb chaws:

• Lub Tebchaws Yelemees - 13Mn6.
• Japan - SB49.
• Tuam Tshoj - 12Mn.
• Russia - 09G2 lossis 10G2S.

Feem ntau, qib steel no muaj ntau heev hauv kev lag luam, yog li txawm tias cov npe me me no ntau tshaj qhov txaus los nrhiav cov qib steel koj xav tau nyob rau txhua lub ces kaum ntawm lub ntiaj teb.
