Umqulu uyinxalenye ebalulekileyo ye-rolling Mill kwi-ilitye lokusila.Uxinzelelo oluveliswa ngamabini okanye iqela lemiqulu lisetyenziselwa ukugoba intsimbi.Ikakhulu inempembelelo yemithwalo eguquguqukayo kunye ne-static, ukunxiba kunye nokutshintsha kweqondo lokushisa ngexesha lokuqengqeleka.
Kukho iindidi ezimbini zemiqulu: i-hot roll kunye ne-cold roll.
Izinto zemiqulu yomsebenzi kwimiqulu ebandayo ebandayo ziquka i-9Cr, 9cr2,9crv, 8crmov, njl. Imiqulu ebandayo ifuna ukucinywa komphezulu, kunye nobunzima hs45 ~ 105.
Izinto eziqhelekileyo ezisetyenziselwa ukutshisa i-roller rollers yi-55mn2,55cr, 60CrMnMo, 60simnmo, njl. njl. , kwaye i-hot roll isebenza kwiqondo lokushisa eliphezulu, kwaye ivumela ukunxiba kwe-diameter ngaphakathi kweyunithi yomsebenzi, ngoko ayifuni ubunzima bomhlaba, kodwa amandla aphezulu kuphela, ukuqina kunye nokumelana nokushisa.Umqulu oshushu wokuqengqeleka uqhelekile kuphela okanye ucinywe ngokupheleleyo, kwaye ubulukhuni bomphezulu bufuneka ukuba bube yi-hb190~270.Ubunzima bobunzima bubunzima bomzimba obungathanga ngqo, kwaye inqanaba layo lichaphazelekayo yimeko yangaphakathi yombutho we-roll ngokwayo, njengobunzima be-matrix yempahla yomqulu, uhlobo kunye nobuninzi be-carbides kwizinto eziphathekayo, uxinzelelo olushiyekileyo roll, njalo njalo;Kwangaxeshanye, ngenxa yokuba unxweme oluqhele ukusetyenziswa kunye novavanyo lobulukhuni beLeeb lovavanyo lobulukhuni bokutyhutyha luvavanyo lobulukhuni obuphindiweyo, luchatshazelwa kakhulu yimeko yezixhobo zokuvavanya, imiba yezengqondo yabaqhubi kunye nezinye izinto.Ngoko ke, amasebe okuvelisa kunye nokusetyenziswa kwemiqulu kufuneka abele abasebenzi abakhethekileyo ukuba babe noxanduva lokuvavanya ubulukhuni, ingqalelo ekukhethweni komvavanyi wobulukhuni, kunye nobudlelwane bokuthelekisa kunye nobunye ubunzima kufuneka buzinze.Ngexesha elifanayo, qaphela ukungeniswa rhoqo kunye nokulinganisa izixhobo zokuvavanya ubulukhuni kunye neebhloko zovavanyo oluqhelekileyo.Amashishini afanelekileyo anokukhuthaza ukusetyenziswa kwemiqulu esemgangathweni yokulinganisa umvavanyi wobulukhuni.
