I-cross rolling iyindlela yokugingqa phakathi kwe-longitudinal rolling kanye ne-cross rolling. Ukugingqika kocezu olugoqiwe kuzungeza ku-eksisi yayo, ukonakala kanye nokuthuthuka phakathi kwamaroli amabili noma amathathu ama-ax awo amade ahlangana (noma ahlehle) ohlangothini olufanayo lokuzungezisa. I-cross rolling isetshenziselwa ikakhulukazi ukubhoboza kanye nokugingqa amapayipi (njengokukhiqizwa kwamapayipi angenamthungo anwetshiwe), kanye nokugingqika kwezigaba zamabhola ensimbi.

Indlela ye-cross-rolling isetshenziswe kakhulu ohlelweni lokukhiqiza amapayipi angenamthungo anwetshiwe anwetshiwe. Ngaphezu kwenqubo eyinhloko yokwandisa okushisayo yokubhoboza, iphinde isetshenziselwe ukugoqa, ukulinganisa, ukulinganisa, ukunweba, ukunwetshwa nokuphotha, njll. inqubo eyisisekelo.

Umehluko phakathi kwe-cross rolling kanye ne-longitudinal rolling kanye ne-cross rolling ikakhulukazi ku-fluidity yensimbi. Isiqondiso esiyinhloko sokugeleza kwensimbi ngesikhathi sokugoqa i-longitudinal sifana naleyo ye-roll surface, futhi isiqondiso esiyinhloko sokugeleza kwensimbi ngesikhathi sokugoqa siyafana naso se-roll surface. I-Cross rolling iphakathi kwe-longitudinal rolling kanye ne-cross rolling, futhi isiqondiso sokugeleza kwensimbi ekhubazekile Yakha i-engeli enesiqondiso sokunyakaza kwe-deformation tool roll, ngaphezu kokuya phambili, insimbi ibuye ijikeleze izungeze i-eksisi yayo, okuyi-axis yayo. ukunyakaza okuya phambili. Kunezinhlobo ezimbili zama-skew rolling mill ezisetshenziswa ekukhiqizeni: ama-roll amabili kanye namasistimu ama-roll amathathu.

Inqubo yokubhoboza ekukhiqizeni ipayipi lensimbi engenamthungo elinwetshiwe elinwetshiwe linengqondo namuhla, futhi inqubo yokubhoboza yenziwe ngokuzenzakalelayo. Yonke inqubo yokubhoboza ukuwela ingahlukaniswa ngezigaba ezi-3:
1. Inqubo engazinzile. Insimbi engaphambili ekupheleni kweshubhu engenalutho kancane kancane igcwalisa isigaba sezoni ye-deformation, okungukuthi, ithubhu elingenalutho futhi umqulu uqala ukuxhumana nensimbi yangaphambili bese uphuma endaweni yokuguqulwa. Kulesi sigaba, kukhona ukulunywa okuyisisekelo kanye nokulunywa kwesibili.
2. Inqubo yokuzinza. Lesi yisigaba esiyinhloko senqubo yokubhoboza, kusukela ensimbi ekupheleni kwepayipi elingenalutho kuya endaweni yokuguqulwa kuze kube yilapho insimbi ekugcineni komsila we-tube ingenalutho iqala ukushiya indawo yokuguqulwa.
3. Inqubo engazinzile. Insimbi ekupheleni kweshubhu ingenalutho kancane kancane ishiya indawo yokuguqulwa kuze kube yilapho yonke insimbi ishiya umqulu.

Kunomehluko ocacile phakathi kwenqubo ezinzile kanye nenqubo engazinzile, engabonwa kalula ohlelweni lokukhiqiza. Isibonelo, kunomehluko phakathi kobukhulu bekhanda nomsila kanye nosayizi ophakathi we-capillary. Ngokuvamile, ububanzi bomkhawulo wangaphambili we-capillary bukhulu, ububanzi bomsila womsila buncane, futhi ingxenye ephakathi iyavumelana. Ukuchezuka kosayizi omkhulu wekhanda kuya komsila kungenye yezici zenqubo engazinzile.

Isizathu sobubanzi obukhulu bekhanda ukuthi njengoba insimbi engaphambili igcwalisa kancane kancane indawo yokuguquguquka, amandla okungqubuzana endaweni yokuxhumana phakathi kwensimbi nomqulu akhula kancane kancane, futhi afinyelela inani eliphakeme ekuguqulweni okuphelele. indawo, ikakhulukazi lapho ukuphela kwangaphambili kwe-tube billet kuhlangana nepulaki Ngesikhathi esifanayo, ngenxa yokumelana kwe-axial yepulaki, insimbi iphikisana nesandiso se-axial, ukuze i-axial extension deformation incishiswe, kanye nokuguqulwa kwe-lateral. iyanda. Ngaphezu kwalokho, awukho umkhawulo wokuphela wangaphandle, okuholela kububanzi obukhulu bangaphambili. Ububanzi bokuphela komsila buncane, ngoba lapho ukuphela komsila we-tube blank kungena ipulaki, ukumelana kwepulaki kwehla kakhulu, futhi kulula ukunweba nokukhubazeka. Ngesikhathi esifanayo, ukugoqa kwe-lateral kuncane, ngakho ububanzi bangaphandle buncane.

Ama-jam angaphambili nangemuva avela ekukhiqizeni nawo angezinye zezinto ezingazinzile. Nakuba lezi zinqubo ezintathu zihlukile, zonke zibonakala endaweni efanayo yokuguquguquka. I-deformation zone yakhiwe ngama-roll, ama-plugs nama-discs omhlahlandlela.
