Ngokukhiqizwa kwensimbi, ingxenye ngayinye enqubweni idlala indima ebalulekile ekuqinisekiseni ikhwalithi nokusebenza kahle komkhiqizo wokugcina. Enye yezakhi ezisemqoka yi-roller yensimbi eshisayo, eyaziwa nangokuthiI-Chromium yensimbi ephezulu or cast iron roller, isetshenziswe kumamitha okugoqa insimbi.

Ama-roll e-hot rolled yensimbiyingxenye ebalulekile yenqubo yokugoqa insimbi njengoba ithinta ngqo ikhwalithi nezakhiwo zensimbi ekhiqizwayo. Lawa ma-roll anenjinizo ukumelana nengcindezi enkulu nokushisa kwenqubo yokugoqa, okwenza ukuba kube yingxenye ebaluleke kakhulu yanoma yisiphi isigayo sensimbi.

Ukusetshenziswa kwe-chromium yensimbi ephezulu kakhulu kuma-rolling mills kunezinzuzo eziningi ezihlukile. Lawa ma-rolls ayaziwa ngamandla abo ahlukile nokuqina, okubavumela ukuba abekezelele amazinga okushisa aphezulu nezingcindezi zenqubo yokugoqa ngaphandle kokulimala noma ukuqhekeka. Ngakho-ke, banikela ekukhiqizweni kwensimbi ezizinzile, ezisezingeni eliphakeme.

Ngokwengeziwe, okuqukethwe okuphezulu kwe-chromium kwalawa ma-roller kwandisa ukumelana kwabo, ukunweba impilo yabo yenkonzo kanye nokunciphisa imvamisa yokubuyiselwa esikhundleni. Lokhu akugcini nje ngokunciphisa izindleko zokulungiswa kepha futhi kuqinisekisa ukukhiqizwa okungaphazanyiswanga, ngaleyo ndlela kwandise ukusebenza kahle kwesigayo esigoqisayo.

Ama-roll e-hot rolled yensimbiyingxenye ebalulekile yenqubo yokugoqa insimbi njengoba ithinta ngqo ikhwalithi nezakhiwo zensimbi ekhiqizwayo.

Ngakho-ke, banikela ekukhiqizweni kwensimbi ezizinzile, ezisezingeni eliphakeme.

Ngokwengeziwe, ukusetshenziswa kwama-castron rolls kuma-rolling mills kunikeza ukuqedwa okuhle kwendawo kanye nokunemba okubucayi kokucutshungulwa kwensimbi. Ingaphezulu elibushelelezi futhi elifanayo lama-roller linikeza insimbi lezi zinto ezifiselekayo, okwenza lilungele izinhlelo eziningi zezicelo ezimbonini ezahlukahlukene.

Empeleni, ama-roller ensimbi ashisayo akayona nje ingxenye eyisisekelo yesigayo esigoqisayo; Bangumgogodla wayo yonke inqubo yokukhiqiza insimbi. Amandla abo ahlukile, ukuqina nokumelana nokugqoka kubenza bahlangene ekuqinisekiseni ikhwalithi, ukusebenza kahle kanye nokwethenjwa kokukhiqizwa kwensimbi.

Kodwa-ke, naphezu kwesimo esisemaphethelweni emilobi eshisayo esongwe yensimbi, isadinga ukulungiswa njalo kanye nokuxhaswa ukuqinisekisa ukusebenza kahle. Ukuthambisa okufanelekile kanye nokuhlola okujwayelekile kubalulekile ekuvimbeleni ukugqoka ngaphambi kwesikhathi nokunweba impilo yalezi zinto ezibucayi. Ama-auptors ensimbi angenayo kumele futhi aphapheme ekutholeni noma yiziphi izimpawu zokugqoka noma ukulimala kuma-roll ukugwema noma yikuphi ukuphazamiseka kokukhiqiza okungaba khona.

Ukufingqa, ama-roller ensimbi agoqiwe, ama-roller aphezulu we-chromium, futhi ama-cast rolling ama-roller ayizinto ezisemqoka zokugaya amalunga. Amandla abo ahlukile, ukuqina kanye nokumelana kokugqoka kubenza babe balulekile ekuqinisekiseni ikhwalithi, ukusebenza kahle kanye nokwethenjwa kokukhiqizwa kwensimbi. Ngokutshala imali kuma-rolls wensimbi esezingeni eliphakeme kakhulu futhi unikeze ukulungiswa okujwayelekile, amalambu ensimbi angakhulisa izinqubo zawo zokukhiqiza futhi athole imiphumela emihle ngensimbi abayikhiqizayo.
