Hauv kev lag luam ntawm cov tshuab tsim khoom thiab cov ntaub ntawv tshawb fawb, kev tsim khoom thiab kev ua haujlwm ntawm cov hlau muaj qhov cuam tshuam tseem ceeb rau nws cov kev ua tau zoo thiab kev siv. Cold rolled steel thiab kub dov hlau yog ob txoj kev ua hlau, uas muaj qhov sib txawv tseem ceeb hauv cov txheej txheem ntws, cov khoom siv, thiab daim ntawv thov. Kab lus no yuav tshawb txog cov yam ntxwv, txheej txheem tsim khoom, qhov zoo, thiab daim ntawv thov scenarios ntawm txias dov steel thiab kub dov hlau los ntawm kev xav ntawm mechanical engineering.
1. Cov txheej txheem ntau lawm:
Kub dov hlau
Cov txheej txheem ntau lawm ntawm cov hlau kub dov yog kom sov cov hlau billet saum toj no qhov kub ntawm recrystallization (feem ntau nyob ib ncig ntawm 1000 degree C), thiab ces yob nws mus rau hauv cov duab los ntawm ib tug dov zeb. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:
· Cua sov:Tshav kub lub steel billet kom kub kom ncav cuag lub xeev yas.
· Rolling:Los ntawm ib tug series ntawm dov mills, lub steel billet yog compressed thiab stretched rau daim ntawv yuav tsum tau thickness thiab zoo.
· Cua txias:Tom qab dov tiav lawm, cov hlau kub-kuav los tiag yog txias los ntawm huab cua los yog dej kom tawv.
Cold dov hlau
Cold dov steel yog ntxiv rau hauv cov duab los ntawm kev txias thiab dov txheej txheem ntawm chav tsev kub. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:
· Pickling:Kub dov steel coils yog pickled kom tshem tawm oxide nplai thiab impurities.
· Txias Rolling:Los ntawm dov ntau zaus ntawm chav tsev kub, nws ntxiv txo qhov tuab thiab txhim kho qhov zoo ntawm qhov chaw thiab qhov tseeb.
· Annealing:Txhawm rau tshem tawm kev ua haujlwm nyuaj thiab kev ntxhov siab sab hauv, txias-dov steel coils feem ntau yuav tsum tau kho annealing.
· Leveling thiab txiav:Tom qab annealing, steel kauj yog leveled thiab txiav kom tau txais cov khoom kawg.
2. Cov yam ntxwv ntawm cov khoom:
Kub dov hlau
• Nto zoo:Lub nto roughness ntawm kub-kuav los tiag steel yog kuj siab, nrog oxide nplai thiab unevenness.
• Dimensional raug:Vim qhov kub-kub dov, qhov qhov tseeb ntawm qhov kub-kuav los tiag steel yog qhov tsawg, uas ua rau muaj qhov tseem ceeb ntawm cov tuab tuab.
• Mechanical zog:Kub dov hlau muaj coarse nplej, tsis tshua muaj zog thiab hardness, tab sis zoo plasticity thiab toughness vim tsis kho annealing.
Cold dov hlau
• Nto zoo:Qhov saum npoo ntawm cov khaub thuas dov steel yog du thiab zoo, haum rau cov ntawv thov uas xav tau qhov zoo ntawm qhov chaw.
• Dimensional raug:Cold rolled steel muaj qhov tseeb qhov tseeb thiab me me thickness kam rau ua.
• Mechanical zog:Tom qab txias dov thiab annealing kev kho mob, txias-kuav los tiag steel muaj zog dua thiab hardness, tab sis kuj qis plasticity thiab toughness.
3. Qhov zoo thiab daim ntawv thov:
Kub dov hlau
Qhov zoo:
• Tus nqi qis:Cov txheej txheem ntau lawm yog qhov yooj yim thiab tus nqi kuj tsawg.
• Zoo plasticity:haum rau kev tsim cov khoom loj loj, yooj yim rau kev ua thiab vuam.
Daim ntawv thov:
• Lub tsev tsim:Kub dov steel yog dav siv nyob rau hauv lub tsev tsim xws li steel beams, txhua, thiab lwm yam.
• Cov tshuab hnyav:siv los tsim thav duab rau ntau yam khoom siv tshuab loj thiab tsheb.
Cold dov hlau
Qhov zoo:
• High precision:haum rau cov khoom uas xav tau high precision thiab zoo nto zoo.
• Siab zog:Tom qab txias ua thiab annealing, nws muaj zog thiab hardness.
Daim ntawv thov:
• Automotive kev lag luam:Cold dov steel yog dav siv nyob rau hauv kev tsim cov tsheb lub cev thiab cov khoom.
• Kev tsim khoom siv hauv tsev:siv los tsim cov casings ntawm cov khoom siv hauv tsev xws li tub yees thiab tshuab ntxhua khaub ncaws.
• Cov cuab yeej Precision:Tsim nyog rau kev tsim cov cuab yeej precision thiab cov cuab yeej siv uas xav tau qhov siab qhov tseeb thiab qhov zoo.
4．Cov ntsiab lus:
Muaj qhov sib txawv tseem ceeb ntawm cov hlau txias thiab cov hlau kub-kuav los tiag hauv cov txheej txheem tsim khoom, cov yam ntxwv ntawm cov khoom siv, thiab daim ntawv thov. Kub dov hlau yog tsim rau cov qauv tsim thiab cov tshuab hnyav vim nws tus nqi qis thiab zoo plasticity; Cold rolled steel yog dav siv nyob rau hauv kev lag luam tsheb, khoom siv hauv tsev, thiab cov cuab yeej precision vim nws qhov siab precision, siab nto zoo, thiab lub zog siab. Thaum xaiv cov hlau, cov kws kho tshuab yuav tsum xaiv cov hlau txias lossis cov hlau kub kub uas tsim nyog raws li cov ntawv thov tshwj xeeb thiab cov kev xav tau ntawm kev ua haujlwm, txhawm rau ua tiav qhov kev ua tau zoo tshaj plaws thiab cov txiaj ntsig kev lag luam.
Txhua qhov kev nug ntsig txog, thov koj xav tiv tauj peb txhua lub sijhawm.
