Maitiro ekugovera iwo ekuwedzera coefficients ega ega slot yeSingle Stand Multi-Groove Reducing Rolling Mill zvine musoro.

        Mamiriro ose aSingle Stand Multi-Groove Reducing Rolling Millgovana zvakafanana roll set, stand uye main drive. Machubhu akawanda anokungurutswa panguva imwe chete. Kusiyana neakawanda-akamira anoenderera saizi mill, haina yakazvimirira yekumira yekumhanyisa gadziriso kutsiva kuyerera musiyano pakati pemagrooves. Naizvozvo, musimboti wemusimboti wekugovera elongation ndeyekuchengeta simbi inoyerera inoyerera kune yega yega groove. Kusaenzana elongation kugoverwa kunotungamira mukutsemuka kwechubhu, murwi-up, kukwenya uye mativi kunze kwekushivirira.

Basic allocation musimboti

       Equal volumetric flow rate ndiwo mutemo wekutanga. Panguva imwe chete yekumhanyisa roll, chigadzirwa cheinouya chemhiri-chikamu nzvimbo uye elongation coefficient ichave padhuze kune yega yega groove.

       Iyo elongation coefficient yegroove yega yega haifanirwe kusiyana zvakanyanya. Yakaganhurirwa nekusimba kwekumira, roll elastic deformation uye isina kuenzana groove kupfeka, mutsauko uripo pakati pema grooves uchachengetwa uri mudiki. Magrooves ane deformation yakaoma anowana kureba kwakadzika, nepo magroove ari pasi pemamiriro akanaka anogona kutora kurebesa zvishoma.

       Elongation yegroove yega haigoni kudarika muganhu wekugadzira wezvinhu. Kune simbi isina tsvina uye alloy simbi ine yakakwirira deformation kuramba, single-pass elongation inofanira kuderedzwa. Carbon simbi machubhu anogona kutora hunhu hwepamusoro. Kupararira kweiyo pass profile kunofanirwawo kutariswa kudzivirira zvimbi uye mapete.

Zvinhu zvinofanirwa kutariswa pakugovera

       1. Nzvimbo yeGroove: Grooves pakati uye mativi ose echigadziko ane mitoro yakasiyana uye mamiriro ekutonhora. Side grooves inowanzoitika kune isina kuenzana mutoro, saka elongation yavo haifanirwe kuiswa yakakwira zvakanyanya.

       2. Kupinda kwezvinhu kushivirira: Kana iyo inopinda chubhu yeimwe groove ine urombo hwemadziro ukobvu kana ovality, ayo elongation coefficient inofanira kuderedzwa kudzivirira kubhuroka uye kupeta kwemukati.

       3. Roll kupfeka tendency: Outer grooves inowanzopfeka nekukurumidza. Allowance ichachengeterwa mupass design. Roll gap kugadzirisa inosarudzwa kuti muripo pane shanduko huru yekugovera elongation.

       4. Equipment load: Rolling load kubva kune ese magrooves anoita pane imwechete stand uye spindle. Yese torque inofanirwa kutariswa kunze kweimwe groove mutoro kudzivirira mota kuwandisa uye kumira kutsauka.

Matambudziko chaiwo anokonzerwa nekugovewa kusina musoro

       Kuwedzeredza kurebesa pane imwe groove: Iyo chubhu yakatambanudzwa-yakanyanya, inotenderera kumutsipa, kuputsika uye mutete madziro.

       Kusakwana kurebesa pagomba rimwe chete: Kuyerera kwesimbi kunononoka kunokonzeresa mirwi, kukwenya kwechubhu, kumaka roll uye dhayamita rekunze.

       Kutsauka kwakakura pakati pemagirovhosi: Kupindirana kwekunetsana pakati pemachubhu, kusarongeka kwema dimensional kuenderana uye kusagadzikana batch mhando.

Pasaiti kugadziriswa kwemazano

       Elongation inotangwa yakagovaniswa panguva yekupasa dhizaini. Mushure mekuedza kutenderedzwa, dhayamita rekunze, ukobvu hwemadziro, mamiriro ekunze uye mota ikozvino yegroove yega yega inorekodhwa. Kune ma grooves ane high current uye anogara achitsemuka, kuderedza kureba. Kune ma grooves ane yakaderera ikozvino uye oversized chubhu, zvishoma kuwedzera elongation kana kugadzirisa roll gap.

       Fine tuning ye roll gap inosarudzwa. Iyo yekutanga elongation yekugovera chirongwa chedhizaini yekupasa inofanirwa kuchengetwa kusvika pazvinogoneka.
