Slip phenomenon inoitika panguva yekukunguruka, kureva, iyo hama inotsvedza pakati pemutsetse neiyomill rolls, muchidimbu, iyo deformation zone yemutsetse inotsiviwa zvachose neyekumberi kana kumashure inotsvedza zone.Slip phenomenon inoitika zvishoma inokanganisa kunaka kwepamusoro uye goho remutsetse, kana kukonzera kutsemuka murwi wetsaona dzesimbi, mutsvakiridzo yakapfuura, vanhu vanowanzongoita pamberi pekutsvedza kukosha kana saizi yeukoshi hwakakwana hweiyo isina kwayakarerekera. hwaro hwekuona mukana wekutsvedza, kuti diki kukosha kwekutsvedza kwemberi kana kona isina kwayakarerekera, ndiko kunowedzera mukana wekutsvedza chiitiko.Muchokwadi, izvi hazvisi zvesainzi zvakanyanya.Somuenzaniso, kunetandem inotonhora inokunguruka, kona yekusarerekera kwechigadziko chekupedzisira, kukosha kwakakwana kwekutsvedza kwepamberi kunofanirwa kunge kuri kudiki pane yekutanga miitiro, asi izvi hazvireve kuti chigadziko chinogona kutsvedza.
1. Kumhanyisa kumhanya
Nekuwedzera kwekumhanya kwekumhanyisa, kuwanda kweiyo lubricant firimu kunowedzera, iyo coefficient of friction inoderera, mukana wekutsvedza unowedzera, uye nzira yekutenderera inova isina kugadzikana.Asi nekuda kwekugadzirwa kwemazuva ano, nzira yekuvandudza kugadzirwa kwekugadzira, kumhanyisa-kumhanya kwakave chinangwa chemutsara wekugadzira, saka mukudzivirira uye kutonga kwekutsvedza hakufanirwe kunge kuri kudhura kwekumhanya semutengo.
2. Lubrication system
Kusanganisira iyo yakasiyana-siyana yekuzora fluid, concentration, tembiricha, zvichingodaro, zvinokanganisa ukobvu hwefirimu remafuta kuburikidza nekuchinja kwe viscosity.For theTandem Cold Mill, sarudzo yekuzora sisitimu inoita basa rakakosha mukudzivirira uye kutonga kwekutsvedza ndeimwe yenzira huru.Kuburikidza nekuongorora, tinogona kuziva kuti nekuwedzera kwemafuta ekuzora viscosity, kukora kwemafuta ekuzora firimu kunowedzera, iyo friction coefficient inoderera, uye, sezvo kusungirirwa kunowedzera uye tembiricha inoderera, iyo yekuzora fluid viscosity inowedzera.Nenzira iyi, kunechando chinokungurukainogara ichitsvedza rack (kazhinji iyo penultimate rack), unogona kudzivirira kutsvedza nekudzikisa zvakakodzera kuwanda kwemafuta ekuzora uye nekuvandudza tembiricha yemafuta ekuzora.
3. Tension system
Nekuwedzera kwemashure-tension, deformation zone lubrication layer ukobvu unowedzera, saka kuti ive nyore kutsvedza rack, inogona kuderedzwa nemazvo ne-post-tension kudzivirira kutsvedza.
4. Mill Rollroughness
Roll roughness inonyanya kukanganisa friction coefficient, sezvo roll roughness inoderera, iyo friction coefficient inodererawo, kutsvedza kuri nyore kuitika.Kazhinji kutaura, roughness uye rolling tonnage ine hukama zvakanyanya nekutsiviwa nenguva kwema rolls kubatsira kudzivirira kutsvedza.
