Piv nrog rau kev kub dov, kev ua haujlwm txias muaj qhov zoo hauv qab no: nws tuaj yeem tsim cov kab loj loj nyias-walled kav; nws muaj qhov siab geometrical qhov tseeb; nws muaj qhov chaw siab kawg; Nws muaj txiaj ntsig zoo rau cov nplej ua kom zoo, thiab nrog rau cov txheej txheem kev kho cua sov, nws tuaj yeem tau txais cov khoom siv kho tshuab ntau dua: nws tuaj yeem tsim ntau yam khoom tshwj xeeb thiab cov khoom sib txawv, nrog rau qee cov ntaub ntawv nrog nqaim kub ua haujlwm kub, qis siab. kub toughness thiab zoo chav tsev kub plasticity. Qhov zoo tshaj plaws ntawm qhov txias dov yog nws lub zog txo cov phab ntsa. Nws tseem tuaj yeem txhim kho qhov ua tau zoo, qhov tseeb qhov tseeb thiab qhov zoo ntawm cov khoom tuaj. Qhov kev txo qis ntawm qhov txias txias yog qis dua qhov txias dov, tab sis cov cuab yeej siv tau yooj yim dua, cov cuab yeej siv tsawg, cov khoom siv tau yooj yim, thiab cov khoom lag luam cov ntsiab lus tseem loj dua. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum sib xyaw ua ke txias dov thiab txias txheej txheem ntawm qhov chaw. Nyob rau hauv xyoo tas los no, txias nro txo, txias ua welded kav, thiab txias txias txheej txheem ntawm super-ntev kav yuav ua rau kom cov zis ntawm lub tsev, nthuav ntau yam ntawm ntau yam thiab specifications, txhim kho qhov zoo ntawm welds, thiab muab cov ntaub ntawv tsim yeeb nkab. rau txias dov thiab txias kos duab. Tsis tas li ntawd, kev ua kom sov tau txais kev saib xyuas ntau hauv xyoo tas los no. Feem ntau, induction cua sov yog ua rau 200-400 degree los txhim kho lub plasticity ntawm lub raj dawb paug. Qhov siab tshaj plaws elongation ntawm sov dov yog hais txog 2-3 lub sij hawm ntawm txias dov; qhov tawg shrinkage tus nqi ntawm cov duab sov yog nce 30%. Nws muaj peev xwm ua tiav qee cov hlau uas tsis tshua muaj plasticity thiab siab zog.
