I-High-Speed ​​Steel Rolls

I-Roll iyingxenye ebalulekile ye-umshini wokugayaphakathi kuinsimbi rolling mill, kusetshenziswa ipheya noma iqembu lamaroli ukuze kuginqike ingcindezi ekhiqizwa lapho kuginqika insimbi.Ibhekene kakhulu nomthwalo oguquguqukayo kanye no-static, ukuguga kanye noshintsho lwezinga lokushisa.

I-Rolling Mill Rollsihlukaniswe yaba izinhlobo ezimbili zama-hot rolls nama-cold rolls.

Izinto ezisetshenziswa kakhulu zamaroli abandayo zifaka i-9cr, 9cr2, 9crv, 8crmov, njll. Ama-Cold rolls adinga ukucishwa kwendawo kanye nobulukhuni be-hs45~105.

Izinto ezijwayelekile zama-hot rolls yi-55mn2,55cr,60crmnmo,60simnmo, njll.Imiqulu eshisayo isetshenziswa ekucubunguleni amabhilidi avulekile, amapuleti awugqinsi, izigaba nokunye.Ingaphansi kwamandla anamandla okugoqa, ukugqoka okukhulu kanye nemiphumela yokukhathala okushisayo, futhi ama-hot rolls asebenza emazingeni okushisa aphezulu futhi avumele ukugqoka kwe-diameter ngayinye yeyunithi yomsebenzi, ngakho-ke ayidingi ukuqina kwendawo, amandla aphezulu kuphela, ukuqina nokumelana nokushisa.Amaroli ashisayo asebenzisa kuphela ukujwayelekile konke noma ukucisha, izidingo zokuqina kwendawo hb190 ~ 270.

Ukusetshenziswa kwehigh-speed steel imiqulukuyingxenye ebalulekile yokuthuthukiswa kokukhiqizwa kwensimbi yesimanjemanje, okuwushintsho olukhulu ekuthuthukisweni kwemboni yensimbi kulandela ubuchwepheshe be-micro-alloying, ukugingqika okulawulwayo kanye nokupholisa.Imiqulu yensimbi enesivinini esikhuluziye zasetshenziswa kabanzi emkhakheni wokukhiqiza ipuleti, isigaba, ibha kanye nenduku yocingo, hhayi nje kuphela emigqeni yokusebenza, kodwa futhi nasekusekeleni imiqulu.Ukumelana okuhle kokugqokwa kwamaroli ensimbi anesivinini esikhulu akunakuhlukaniswa nezici zawo ezihluke kakhulu kumaroli wendabuko.
