Lub tshuab txias dov yog ib qho tseem ceeb ntawm cov khoom siv hauv kev lag luam hlau, lub luag haujlwm rau kev hloov cov nplooj ntawv hlau rau hauv ntau yam khoom, nrog rau cov kav dej, cov ntawv, thiab cov tuav. Lub tshuab no tso cai rau kev tswj xyuas meej ntawm cov duab, kev ntxhib los mos, thiab tuab, ua rau nws yog ib feem tseem ceeb ntawm cov txheej txheem tsim khoom. Ntawm no yog ib qho kev piav qhia ntawm lub tshuab txias dov thiab nws cov haujlwm.
Lub Tshuab Txias Rolling:
Lub tshuab txias dov muaj cov txheej txheem ntawm cov yob los yog yob uas tig ntawm kev kub ceev. Cov ntawv hlau lossis phaj yog pub rau hauv cov yob, uas compress thiab deform cov hlau, maj mam txo nws cov thickness thiab nce nws lub zog.
Kev ua haujlwm ntawm Lub Tshuab Txias Rolling:
Lub tshuab txias dov ua haujlwm ntau yam uas hloov cov ntawv hlau rau hauv cov khoom tiav. Cov haujlwm no suav nrog:
1.Reducing Thickness: Cov tshuab txias dov muaj peev xwm txo tau cov thickness ntawm cov ntawv hlau kom txog li 50 feem pua. Qhov kev txo qis hauv thickness no ua rau muaj zog tensile thiab nruj.
2.Kev Txhim Kho Qhov Nto Zoo: Lub npoo du ntawm cov ntawv txias dov hlau txhim kho nws cov tsos thiab zoo tag nrho. Cov qauv zoo nplej ua tiav los ntawm kev sib tw txias ua kom cov ntawv tsis kam tiv thaiv corrosion thiab hnav.
3.Controlling Shape: Lub tshuab txias dov tuaj yeem hloov kho cov duab ntawm cov ntawv hlau, ua rau cov tuam txhab tsim cov duab nyuaj thiab cov profiles.
4.Controlled Texture: Cov txheej txheem txias dov tswj cov nplej orientation ntawm cov hlau, ua rau anisotropic mechanical zog.
Hom Txias Rolling Tshuab:
Cov tshuab txias dov tau muab cais raws li lawv tsim thiab siv. Qee hom muaj xws li:
1.Single-Stage Cold Rolling Tshuab: Hom tshuab no yog tsim los rau cov khoom me me thiab ua rau muaj qhov txwv ntau ntawm cov duab thiab ntau thiab tsawg.
2.Multi-Stage Cold Rolling Tshuab: Lub tshuab no muaj peev xwm ua tau ntau yam duab thiab ntau thiab tsawg thiab tsim nyog rau cov khoom loj. Nws muaj ntau yam sawv ntsug, txhua tus nrog yob uas maj mam txo cov thickness ntawm cov ntawv hlau.
3.Sendzimir Txias Rolling Tshuab: Hom tshuab no yog tsim los rau kev tsim khoom muaj peev xwm thiab muaj ntau cov yob uas tig ntawm qhov sib txawv kom ua tiav kev tswj xyuas meej ntawm cov tuab, cov duab, thiab kev ntxhib los mos.
4.Mannesmann Txias Rolling Tshuab: Lub tshuab no muaj lub ntsej muag sab sauv thiab sab qis nrog cov yob uas tig rau hauv cov lus qhia rov qab los txhim kho kev tswj xyuas cov hlau ntws thiab ua tiav cov tuab tuab.
Txawm li cas los xij, cov tshuab txias txias ua lub luag haujlwm tseem ceeb hauv kev lag luam hlau, ua rau cov tuam txhab tsim cov khoom lag luam zoo, qhov tseeb ntawm cov khoom siv hlau rau ntau yam kev siv, suav nrog kev tsim kho, kev thauj mus los, thiab kev tsim khoom.
