Tsheb iav

Muaj ntau qib ntawm iav hlau rau 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 txawv teb chaws advanced tsheb tshuab thaum lub sijhawm ntawd. Nyob rau xyoo 1950, Tuam Tshoj tau qhia los ntawm yav dhau los Soviet Union Rikhachev tsheb Hoobkas tsim cov cuab yeej siv tshuab ntawm Soviet Union lub tsheb nruab nrab (uas yog, tus qauv qub ntawm "liberation" hom) tib lub sijhawm, nws kuj tau qhia txog 20CrMnTi steel. qib ntawm yav dhau los Soviet Union los tsim tsheb iav.
Tom qab kev hloov kho thiab qhib, nrog rau txoj kev loj hlob sai ntawm Tuam Tshoj txoj kev lag luam kev tsim kho, 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 1980s, Tuam Tshoj tau npaj los qhia txhua yam ntawm cov qauv siab heev ntawm cov teb chaws tsim kho, thiab txhua yam ntawm txawv teb chaws advanced nruab nrab thiab hnyav tsheb thauj khoom tau 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 cov cuab yeej siv tsheb ntau lawm, suav nrog cov cuab yeej tsim khoom ntawm lub tsheb iav. Nyob rau tib lub sijhawm, Tuam Tshoj cov hlau smelting thev naus laus zis kuj tseem txhim kho tas li, kev siv cov ladle thib ob smelting thiab muaj pes tsawg leeg zoo-tuning thiab nruam casting thiab dov thiab lwm yam kev siv tshuab siab heev, kom steel mills tuaj yeem tsim cov purity siab, hardenability tuaj yeem nqaim iav. steel, thiaj li ua tiav cov kev taw qhia ntawm lub tsheb iav steel localization, thiaj li hais tias Tuam Tshoj lub iav steel ntau lawm qib nyob rau theem tshiab. Lub tsev siab hardenability steel uas muaj npib tsib xee rau iav ntawm lub tsheb hnyav, uas yog tsim 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 50-60's siv cov roj zoo carburizing rauv mus rau tam sim no kev siv computer-tswj nruam roj carburizing tsis siv neeg kab thiab lub thawv-hom multi-purpose rauv thiab tsis siv neeg ntau lawm kab (nrog rau qhov tsis tshua muaj siab (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 technology. Kev siv cov thev naus laus zis no tsis yog tsuas yog ua rau lub iav carburizing thiab quenching distortion yog tswj tau zoo, lub iav machining precision yog txhim kho, kev pab cuam lub neej txuas ntxiv, tab sis kuj ua tau raws li cov kev xav tau ntawm huab hwm coj ntawm kev kho cua sov niaj hnub ntawm cov iav.
Cov ntaub ntawv tseem ceeb qhia tau hais tias lub neej ntawm lub tsheb iav feem ntau yog ntsuas los ntawm ob qhov ntsuas, ib qho yog kev sib cuag qaug zog ntawm cov iav, thiab lwm qhov yog khoov qaug zog ntawm 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. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum muaj kev nkag siab ntau dua ntawm cov kev xav tau, cov khoom siv thiab cov yam ntxwv ntawm kev kho cua sov ntawm carburized steel rau lub zog tsav tsheb.
