Muaj ntau ntau qib steel rau lub zog ntawm nruab nrab thiab hnyav tsheb thauj khoom hauv Suav teb, feem ntau yog ua kom tau raws li qhov yuav tsum tau ua ntawm kev qhia txog kev siv tsheb txawv teb chaws thaum lub sijhawm ntawd. Nyob rau hauv lub 50s, Tuam Tshoj tau qhia txog kev tsim cov cuab yeej ntawm cov tsheb thauj khoom nruab nrab (uas yog, tus qauv qub ntawm "Liberation" hom) los ntawm qub Soviet Union Rikhachev Automobile Plant, thiab kuj tau qhia txog 20CrMnTi steel qib ntawm lub tsheb iav ua nyob rau hauv lub qub Soviet Union.
Tom qab kev hloov kho thiab qhib, nrog rau txoj kev loj hlob sai ntawm Tuam Tshoj txoj kev tsim kho kev lag luam, txhawm rau ua kom tau raws li cov kev xav tau ntawm kev loj hlob sai ntawm Tuam Tshoj txoj kev thauj mus los, txij li xyoo 80s, Tuam Tshoj tau npaj los qhia txhua yam ntawm cov qauv siab heev los ntawm cov teb chaws tsim kho, thiab txhua yam ntawm txawv teb chaws advanced nruab nrab thiab hnyav cargo tsheb kuj tau tsis tu ncua qhia. Nyob rau tib lub sijhawm, Tuam Tshoj cov tuam txhab tsheb loj tau koom tes nrog cov tuam txhab tsheb nto moo txawv teb chaws los qhia txawv teb chaws advanced tsheb tsim tshuab, suav nrog cov cuab yeej siv hluav taws xob ntau lawm. Nyob rau tib lub sijhawm, qib ntawm steel smelting tshuab hauv Suav teb kuj tseem txhim kho tas li, kev siv cov ladle theem nrab smelting thiab muaj pes tsawg leeg zoo-tuning thiab nruam casting thiab dov thiab lwm yam advanced smelting technologies, yog li ntawd steel mills yuav ua tau siab purity, hardened. kev ua tau zoo band nqaim iav steel, thiaj li ua tiav cov kev taw qhia ntawm automotive iav steel localization, thiaj li hais tias Tuam Tshoj lub iav steel ntau lawm qib mus rau theem tshiab. Nickel-muaj siab hardenability steel rau domestic hnyav-duty tsheb gears haum rau Tuam Tshoj lub teb chaws tej yam kev mob kuj tau siv thiab ua tiav cov txiaj ntsig zoo. Kev kho cua sov thev naus laus zis ntawm lub tsheb iav kuj tau tsim los ntawm tus thawj 50-60s siv cov roj zoo carburizing tiv thaiv mus rau qhov tam sim no dav siv computer-tswj nruam roj carburizing tsis siv neeg kab thiab lub thawv-hom multi-purpose rauv thiab tsis siv neeg. Cov kab ntau lawm (xws li lub tshuab nqus tsev (nqus) carburizing tshuab), iav carburizing pre-oxidation kho tshuab, iav quenching tswj cua txias tshuab (vim siv cov roj tshwj xeeb quenching thiab quenching txias tshuab), iav forging billet isothermal normalizing tshuab, thiab lwm yam. . Kev siv cov thev naus laus zis no tsis yog tsuas yog ua rau carburizing quenching distortion ntawm iav tswj tau zoo, cov iav ua kom raug tau zoo dua qub, thiab kev pab cuam lub neej txuas ntxiv, tab sis kuj ua tau raws li cov kev xav tau ntawm cov khoom loj ntawm kev kho cua sov niaj hnub ntawm cov iav.
Cov ntaub ntawv tseem ceeb qhia tau hais tias lub neej ntawm lub tsheb lub zog yog ntsuas los ntawm ob lub ntsiab lus tseem ceeb, ib qho yog kev sib cuag qaug zog ntawm lub iav, thiab lwm qhov yog qhov khoov qaug zog ntawm lub iav. Qhov qub yog txiav txim siab los ntawm qhov zoo ntawm carburizing thiab quenching, thiab tom kawg yog txiav txim siab los ntawm cov khoom siv iav. Txog rau qhov kawg no, nws yog ib qho tsim nyog yuav tsum muaj kev nkag siab ntau dua ntawm cov kev xav tau, cov khoom siv thiab kev kho cua sov cov yam ntxwv ntawm carburized steel rau cov khoom siv tsheb.
