Ukuqengqeleka komnqamlezo yindlela yokuqengqeleka phakathi kokuqengqeleka kwelongitudinal kunye nokuqengqeleka.Ukuqengqeleka kweqhekeza eliqengqelekayo lijikeleza ecaleni kwe-axis yalo, i-deforms kunye nokuqhubela phambili phakathi kwemiqulu emibini okanye emithathu ene-axes ye-longitudinal edibanisa (okanye incline) kwicala elifanayo lokujikeleza.Ukuqengqeleka komnqamlezo kusetyenziswa ikakhulu ukugqobhoza nokuqengqeleka kwemibhobho (efana nokuveliswa kwemibhobho engenamthungo eyandisiweyo eyandisiweyo), kunye nokuqengqeleka kweebhola zentsimbi ngamaxesha athile.

Indlela yokuwela i-cross-rolling isetyenziswe ngokubanzi kwinkqubo yokuvelisa imibhobho engenamthungo eshushu eyandisiweyo.Ukongeza kwinkqubo yokwandisa i-thermal yokubhoboza, isetyenziselwa ukuqengqeleka, ukulinganisa, ukulinganisa, ukunyusa, ukwandiswa kunye nokujikeleza, njl njl. kwinkqubo esisiseko.

Umahluko phakathi kwe-cross rolling kunye ne-longitudinal rolling kunye ne-cross-rolling ikakhulu kwi-fluidity yesinyithi.Isalathiso esiphambili sokuhamba kwesinyithi ngexesha le-longitudinal rolling ifana neyomgangatho we-roll, kwaye isalathiso esiphambili sokuhamba kwesinyithi ngexesha lokuhamba kwe-cross lifana nelo le-roll surface.Ukuqengqeleka komnqamlezo kuphakathi kokuqengqeleka kwelongitudinal kunye nokuqengqeleka komnqamlezo, kwaye ulwalathiso lokuhamba kwentsimbi egogekileyo lukwenza i-engile kunye nesalathiso sokuhamba komqulu wesixhobo sokuguqula, ukongeza kwintshukumo eya phambili, intsimbi nayo ijikeleza i-axis yayo, eyiyo intshukumo ejikelezayo eya phambili.Kukho iindidi ezimbini ze-skew rolling mill ezisetyenziselwa imveliso: ii-roli ezimbini kunye ne-three-roll systems.

Inkqubo yokubhoboza ekuveliseni umbhobho wensimbi ongenamthungo owandisiweyo oshushu, unengqiqo ngakumbi namhlanje, kwaye inkqubo yokubhoboza yenziwe ngokuzenzekelayo.Yonke inkqubo yokugqobhoza okunqamlezayo inokwahlulwa ibe ngamanqanaba ama-3:
1. Inkqubo engazinzanga.Isinyithi kwisiphelo sangaphambili setyhubhu engenanto ngokuthe ngcembe igcwalisa inqanaba lendawo ye-deformation, oko kukuthi, i-tube engenanto kunye ne-roll iqala ukuqhagamshelana nentsimbi yangaphambili kwaye iphume kwindawo yokuguqulwa.Kule nqanaba, kukho ukuluma okuphambili kunye nokuluma okwesibini.
2. Inkqubo yokuzinzisa.Le yinqanaba eliphambili lenkqubo yokubhoboza, ukusuka kwintsimbi engaphambili kwisiphelo sombhobho ongenanto ukuya kwindawo yokuguqula kude kube yintsimbi ekupheleni komsila wetyhubhu engenanto iqala ukushiya indawo yokuguqulwa.
3. Inkqubo engazinzanga.Isinyithi ekupheleni kwetyhubhu engenanto ngokuthe ngcembe ishiya indawo ye-deformation de yonke isinyithi ishiya umqulu.

Kukho umahluko ocacileyo phakathi kwenkqubo ezinzileyo kunye nenkqubo engazinzanga, enokubonwa ngokulula kwinkqubo yokuvelisa.Umzekelo, kukho umahluko phakathi kobukhulu bentloko kunye nomsila kunye nobukhulu obuphakathi be-capillary.Ngokuqhelekileyo, ububanzi becala langaphambili le-capillary likhulu, ububanzi bomsila womsila buncinci, kwaye inxalenye ephakathi ihambelana.Ukuphambuka kobungakanani obukhulu bentloko ukuya kumsila yenye yeempawu zenkqubo engazinzanga.

Isizathu sobubanzi obukhulu bentloko kukuba njengoko isinyithi esingaphambili sigcwalisa ngokuthe ngcembe indawo yokuguqulwa, amandla okukhuhlana kwindawo yoqhagamshelwano phakathi kwentsimbi kunye ne-roll inyuka ngokuthe ngcembe, kwaye ifikelela kwixabiso eliphezulu kwi-deformation epheleleyo. ummandla, ngakumbi xa isiphelo sangaphambili se-tube billet sidibana neplagi Ngexesha elifanayo, ngenxa yokumelana ne-axial yeplagi, isinyithi sichaswa kwisandiso se-axial, ukwenzela ukuba i-axial extension deformation iyancipha, kunye ne-lateral deformation. iyanda.Ukongezelela, akukho mda wesiphelo wangaphandle, obangela ububanzi obukhulu bangaphambili.Ububanzi besiphelo somsila buncinci, kuba xa isiphelo somsila wetyhubhu engenanto ingena kwiplagi, ukuchasana kweplagi kwehla kakhulu, kwaye kulula ukwandisa kunye nokukhubazeka.Ngelo xesha, i-lateral rolling incinci, ngoko ububanzi bangaphandle buncinci.

Iijam zangaphambili nasemva ezibonakala kwimveliso nazo zezinye zezinto ezingazinzanga.Nangona ezi nkqubo zintathu zahlukile, zonke zibonwa kwindawo enye yokuguqulwa.Ummandla we-deformation uqulunqwe yimiqulu, iiplagi kunye neediski zesikhokelo.
