Ulwazi oluncane

Umqulu uyingxenye ebalulekile yomshini wokugayaumshini wokugaya.Ukucindezela okukhiqizwa yipheya noma iqembu lemiqulu kusetshenziselwa ukugoqa insimbi.Ithwala ngokuyinhloko ithonya lemithwalo eguquguqukayo kanye ne-static, ukugqoka nokuguquka kwezinga lokushisa ngesikhathi sokugoqa.
Kunezinhlobo ezimbili zemiqulu: i-hot roll ne-cold roll.
Izinto zokwakha zamaroli okusebenza kumaroli abandayo ajwayelekile zifaka i-9Cr, 9cr2,9crv, 8crmov, njll. amaroli abandayo adinga ukucinywa kwendawo, futhi ubulukhuni bungu-hs45~105.
Izinto ezisetshenziswa kakhulu zama-hot roller roller yi-55mn2,55cr, 60CrMnMo, 60simnmo, njll. ama-hot roller rollers asetshenziswa ekucubunguleni i-billet, ipuleti eliwugqinsi, insimbi yesigaba, njll. Ithwala amandla aqinile okugoqa, ukuguga okukhulu nokukhathala okushisayo. , futhi i-hot roll isebenza ekushiseni okuphezulu, futhi ivumela ukugqoka kobubanzi ngaphakathi komthwalo womsebenzi weyunithi, ngakho-ke ayidingi ukuqina kobuso, kodwa amandla aphezulu kuphela, ukuqina nokumelana nokushisa.I-hot rolling roll yenziwa ngokwejwayelekile kuphela noma icinywe iyonke, futhi ukuqina kwendawo kuyadingeka ukuze kube ngu-hb190~270.I-hardness roll hardness iyinani elingokwenyama elingaqondile, futhi izinga layo lithinteka esimweni sangaphakathi senhlangano ye-roll ngokwayo, njengokuqina kwe-matrix yempahla ye-roll, uhlobo kanye nenani lama-carbides ku-roll material, ingcindezi esele ye-roll. roll, njalonjalo;Ngesikhathi esifanayo, ngenxa yokuthi ukuhlola okuvame ukusetshenziswa kogu kanye nokuqina kwe-Leeb kokuhlolwa kokuqina kwe-roll kuwukuhlolwa kokuqina kwe-rebound, kuthintwa kakhulu isimo samathuluzi okuhlola, izici zengqondo zabaqhubi nezinye izici.Ngakho-ke, iminyango yokukhiqiza neyokusetshenziswa kwamaroli idinga ukwabela abasebenzi abakhethekile abazobhekana nokuhlola ubulukhuni, banake ukukhethwa komhloli wokuqina, futhi ubudlelwano bokuqhathanisa nobunye ubulukhuni kufanele buzinze.Ngesikhathi esifanayo, naka ukuhanjiswa okuvamile kanye nokulinganiswa kwamathuluzi okuhlola ubulukhuni namabhulokhi okuhlola ajwayelekile.Amabhizinisi afanelekayo angaphromotha ukusetshenziswa kwamaroli ajwayelekile okulinganisa umhloli wokuqina.
