Slip Prevention And Control Izinyathelo For Tandem Cold Rolling Mill

Isimo sokushelela senzeka phakathi nenqubo yokugingqa, okungukuthi, ukushelela okuhlobene phakathi komugqa kanye neimiqulu yokugaya, empeleni, indawo yokuguquguquka yomugqa ithathelwa indawo ngokuphelele indawo yokushelela yangaphambili noma yangemuva.Isenzakalo sokushibilika senzeka kancane sithinte ikhwalithi engaphezulu kanye nesivuno somucu, noma sibangele inqwaba ephukile yezingozi zensimbi, ocwaningweni oludlule, abantu bavame ukumane babe ngaphambi kwenani elishelelayo noma usayizi wevelu ephelele ye-engeli emaphakathi njenge isisekelo sokunquma amathuba okushelela, ukuthi incane inani langaphambili lokushelela noma i-engeli emaphakathi, maningi amathuba okuba isenzeko slip.Eqinisweni, lokhu akuwona neze isayensi.Ngokwesibonelo, for thei-tandem ebandayo yokugaya, i-engeli engathathi hlangothi yesitendi sokugcina, inani eliphelele lesiliphu sangaphambili kufanele libe lincane kakhulu kunezitendi ezimbalwa zokuqala, kodwa lokhu akusho ukuthi ukuma kungenzeka kushelele.

1. Isivinini sokuginqika

Ngokukhula kwejubane lokugoqa, ukushuba kwefilimu yokugcoba kuyanda, i-coefficient of friction iyancipha, amathuba okushelela ayanda, futhi inqubo yokugoqa iba ingazinzi.Kodwa ngenxa yokukhiqizwa kwesimanjemanje, indlela yokuthuthukisa ukusebenza kahle kokukhiqiza, ukugoqa ngesivinini esikhulu kuye kwaba umgomo womugqa wokukhiqiza, ngakho-ke ekuvimbeleni nasekulawuleni ukushelela akufanele kube ngezindleko zejubane njengentengo.

2. Uhlelo lokuthambisa

Kubandakanya ukuhlukahluka koketshezi lokugcoba, ukugxila, izinga lokushisa, njll., kuthinta ukushuba kwefilimu yokugcoba ngokushintsha kwe-viscosity.OkweI-Tandem Cold Mill, ukukhethwa kwesistimu yokugcoba kudlala indima ebalulekile ekuvimbeleni nasekulawuleni ukushelela kungenye yezinkomba eziyinhloko.Ngokuhlaziya, singakwazi ukwazi ukuthi ngokwanda kwe-viscosity yokugcoba uketshezi, ukushuba kwefilimu kawoyela wokugcoba kuyanda, i-coefficient ye-friction iyancipha, futhi, njengoba ukugxila kukhula kanye nezinga lokushisa liyancipha, i-viscosity yokugcoba i-lubricating iyanda.Ngale ndlela, ku-umshini wokugaya obandayoijwayele ukushelela i-rack (imvamisa i-rack penultimate), unganqanda ukushelela ngokunciphisa ngokufanelekile ukugcwala koketshezi lokuthambisa kanye nokwenza ngcono izinga lokushisa loketshezi lokuthambisa.

3. Uhlelo lwe-tension

Ngokukhula kwe-post-tension, ukujiya kongqimba lwe-deformation zone lubrication kuyanda, ukuze kube lula ukushelela, kungancishiswa ngokufanelekile yi-post-tension ukuvimbela ukushelela.

4. I-Mill Rollubulukhuni

I-roll roughness ithinta kakhulu i-coefficient ye-friction, njengoba ukuqina kwe-roll kuncipha, i-coefficient ye-friction nayo iyancipha, ukushelela kulula ukwenzeka.Ngokuvamile, ukugwedla kweroll kanye nethoni eginqikayo kuhlobene eduze nokushintshwa okufika ngesikhathi kwamaroli ukuze kuvinjwe ukushelela.
