Abubuwan da ke biyo baya sun bayyana gazawar gama gari na Rolls da gabatarwar hanyoyin magani.
1.Roller wear ya kasu kashi uku.
Lalacewar injina yana faruwa ne sakamakon gogayya tsakanin bayyanar nadi da sassan birgima.
Thermal lalacewa yana faruwa ne ta hanyar sakamako na laushin zafin jiki, narkewa ko ƙafewar saman saman.
Lalacewar lalacewa yana haifar da tasirin sinadarai, tasirin electrochemical, tasirin iskar shaka, da dai sauransu na danshi akan saman mirgina, yana haifar da asarar da ƙaura na kayan waje.
2.Roll cracking rolling a cikin samar da tarin karfe, karfe na katin, wutsiya da sauran abubuwan da suka faru, wanda ya haifar da karuwa mai yawa a cikin zafin jiki na sashinsa, sakamakon yanayin zafi da damuwa na tsari ya wuce iyaka, yana haifar da fashewar thermal.
Tsawaita mirgina ya ƙunshi harshe, zafinsa ya yi ƙasa da tsakiyar sassan birgima, zai haifar da damuwa na thermal da kuma jujjuyawar damuwa ba zato ba tsammani, yana haifar da fashewar tasiri, jujjuyawar, saboda jujjuwar tari na ƙarfe oxide, ɓarke tsararrun jagora da sauran dalilai. Har ila yau, ya zama fasa.
3.Roll kashe abun da ke ciki da kuma fadada fashewar hanzari, kaiwa wani tsayi da zurfi, zai haifar da fadi.

1) Roll simintin shortcomings mirgine centrifugal simintin gyare-gyare, saboda centrifugal vibration samar da abun da ke ciki da kuma tsari na laminar segregation, concenting da m fadada fasa, haifar da yi fatattaka.
2)MirgineShirye-shirye shortcomings sinadaran abun da ke ciki ba m, rashin dacewa sanyaya kudi zai kai ga bangaren segregation, carburization jiki ma high shortcomings, kawai inji Properties ƙi, kuma a karshe kai ga fatattaka.
3) aiki tsari Rolls a cikin ƙirƙira matsa lamba ne ma kananan ko m nakasawa lalacewa ta hanyar core na Rolls ba a ƙirƙira ta, constitutioning wani crack ta cikin crystal.Hanyoyin magani.
