1. Kub dov seamless steel yeeb nkab
Kub dov yog hais txog cov cua kub ntawm cov hlau billet rau qhov tsim nyog kub thiab tsim cov yeeb nkab steel seamless los ntawm kev nruam casting thiab dov. Kub dov seamless steel yeeb nkab muaj cov yam ntxwv ntawm lub zog siab, zoo plasticity thiab vuam kev ua tau zoo vim yog lub zoo meej yas deformation ntawm cov nplej hauv cov yeeb nkab steel tom qab ntau cov txheej txheem dov. Nyob rau hauv cov nqe lus ntawm kev xa khoom, cov kav dej kub dov seamless steel tau muab faib ua peb lub xeev: daim tawv nqaij dub, daim tawv nqaij du thiab sib tsoo ntawm daim tawv nqaij. Cov tawv nqaij dub yog lub xeev tsis muaj kev kho mob saum npoo, daim tawv nqaij du yog lub xeev tom qab kev kho deg, thiab kev sib tsoo ntawm daim tawv nqaij yog lub xeev. Kub kub polished xeev.
2. Thaum tshav kub kub kho seamless steel yeeb nkab
Kev kho cua sov ntawm seamless steel yeeb nkab hais txog cua sov, rwb thaiv tsev thiab cua txias ntawm seamless steel yeeb nkab kom nws muaj qee yam khoom siv thiab lub cev. Lub xeev tus me nyuam ntawm tshav kub-kho seamless steel kav yog feem ntau annealed los yog normalized. Lub xeev annealing yog hais txog cua sov cov yeeb nkab steel mus rau qhov kub thiab txias, tuav nws rau ib lub sijhawm, thiab maj mam txias nws mus rau chav sov; lub xeev normalizing hais txog cua sov cov yeeb nkab steel rau ib qho kub, tuav nws rau ib lub sij hawm, thiab tom qab ntawd dej-txias los yog roj-txias kom nws muaj zog dua thiab hardness.
3. Qhov sib txawv ntawm kub-kuav los tiag thiab kub-kho seamless steel kav
Kub dov thiab kev kho cua sov yog ob txoj kev sib txawv hauv kev tsim cov kav dej seamless, thiab cov xwm txheej xa khoom kuj muaj qee qhov sib txawv. Kub dov seamless steel yeeb nkab muaj cov yas zoo, vuam kev ua tau zoo thiab lub zog siab, thiab tsim nyog rau qee qhov kev ua haujlwm siab, kub tsis kam, corrosion kuj thiab lwm yam. Thaum tshav kub kub-kho seamless steel kav muaj zog dua hardness, lub zog thiab lwm yam mechanical zog tom qab annealing los yog normalizing kev kho mob, thiab yog haum rau engineering teb uas yuav tsum tau tiv taus siab dua thiab hnyav loads.
Nyob rau hauv luv luv, thaum xaiv seamless steel kav, kev xaiv yuav tsum tau raws li cov kev xav tau ntawm kev siv tiag tiag thiab kev xa khoom ntawm seamless steel kav. Nyob rau tib lub sijhawm, xyuam xim rau kev yuav khoom tsim los ntawm cov tuam txhab ua lag luam niaj hnub los xyuas kom meej tias lawv qhov zoo thiab kev ua tau zoo raws li qhov yuav tsum tau ua.
