Ekukhiqizeni insimbi, ingxenye ngayinye kule nqubo idlala indima ebalulekile ekuqinisekiseni ikhwalithi nokusebenza kahle komkhiqizo wokugcina.Enye yezingxenye ezibalulekile yi-hot roll roll steel, eyaziwa nangokuthihigh chromium iron roller or i-cast iron roller, esetshenziswa ku-Steel Rolling Mills.

Imiqulu yensimbi egoqiwe eshisayoziyingxenye ebalulekile yenqubo yokugoqa insimbi njengoba zithinta ngokuqondile ikhwalithi kanye nezakhiwo zensimbi ezikhiqizwayo.Lawa ma-roll akhiwe ngendlela yokuthi amelane nokucindezela okukhulu nokushisa kwenqubo yokugingqika, okuwenza abe ingxenye ebalulekile kunoma iyiphi indawo yokugaya insimbi.

Ukusetshenziswa kwamaroli e-iron e-chromium aphezulu kuma-rolling anezinzuzo eziningana ezihlukile.Lawa maroli aziwa ngamandla awo akhethekile nokuqina kwawo, okuwavumela ukuthi amelane nezinga lokushisa eliphezulu nezingcindezi zenqubo yokugingqika ngaphandle kokonakala noma ukuqhekeka.Ngakho-ke, bafaka isandla ekukhiqizeni insimbi ezinzile, ephezulu.

Ukwengeza, okuqukethwe okuphezulu kwe-chromium kwalawa marola kukhulisa ukumelana nokugqokwa kwawo, kunwebe impilo yawo yesevisi futhi kunciphisa imvamisa yokushintshwa.Lokhu akunciphisi nje kuphela izindleko zokulungisa kodwa futhi kuqinisekisa ukukhiqizwa okungaphazamiseki, ngaleyo ndlela kwandise ukusebenza kahle okuphelele kwesigayo.

Imiqulu yensimbi egoqiwe eshisayoziyingxenye ebalulekile yenqubo yokugoqa insimbi njengoba zithinta ngokuqondile ikhwalithi kanye nezakhiwo zensimbi ezikhiqizwayo.Lawa ma-roll akhiwe ngendlela yokuthi amelane nokucindezela okukhulu nokushisa kwenqubo yokugingqika, okuwenza abe ingxenye ebalulekile kunoma iyiphi indawo yokugaya insimbi.

Ukusetshenziswa kwamaroli e-iron e-chromium aphezulu kuma-rolling anezinzuzo eziningana ezihlukile.Lawa maroli aziwa ngamandla awo akhethekile nokuqina kwawo, okuwavumela ukuthi amelane nezinga lokushisa eliphezulu nezingcindezi zenqubo yokugingqika ngaphandle kokonakala noma ukuqhekeka.Ngakho-ke, bafaka isandla ekukhiqizeni insimbi ezinzile, ephezulu.

Ukwengeza, ukusetshenziswa kwamaroli ensimbi okusansimbi ezigayweni eziginqikayo kunikeza isiphetho esihle kakhulu esingaphezulu kanye nokunemba kobukhulu ensimbi ecutshungulwayo.Ubuso obushelelezi futhi obufanayo be-rollers bunikeza insimbi lezi zakhiwo ezifiselekayo, okwenza ifaneleke ezinhlobonhlobo zezicelo ezimbonini ezihlukahlukene.

Empeleni, ama-rollers ensimbi ashisayo awayona nje ingxenye eyisisekelo yomshini wokugoqa;Ziwumgogodla wayo yonke inqubo yokukhiqiza insimbi.Amandla abo angavamile, ukuqina nokumelana nokugqoka kwenza kube yingxenye yokuqinisekisa ikhwalithi, ukusebenza kahle nokuthembeka kokukhiqizwa kwensimbi.

Kodwa-ke, naphezu kwemvelo eqinile yamaroli ensimbi agingqiwe ashisayo, asadinga ukunakekelwa okujwayelekile kanye nokunakekelwa ukuze kuqinisekiswe ukusebenza kahle.Ukugcotshwa okufanele kanye nokuhlolwa okuvamile kubalulekile ekuvimbeleni ukuguga ngaphambi kwesikhathi nokwelula impilo yalezi zingxenye ezibalulekile.Abaqhubi bemishini yokugaya insimbi kufanele futhi baqaphe ukuze bathole noma yiziphi izimpawu zokuguga noma ukulimala kwamaroli ukuze bagweme noma yikuphi ukuphazamiseka okungenzeka kokukhiqiza.

Ngamafuphi, amarola ensimbi agingqiwe ashisayo, amarola ensimbi ane-chromium ephezulu, namarola ensimbi ayizici ezibalulekile ezigayweni.Amandla abo angavamile, ukuqina kanye nokumelana nokugqoka kubenza babaluleke kakhulu ekuqinisekiseni ikhwalithi, ukusebenza kahle nokuthembeka kokukhiqizwa kwensimbi.Ngokutshala imali kumaroli ensimbi aginqike ngekhwalithi ephezulu kanye nokuhlinzeka ngokulungiswa okuvamile, izigayo zensimbi zingathuthukisa izinqubo zazo zokukhiqiza futhi zithole imiphumela emihle kakhulu ensimbi eziyikhiqizayo.
