Ama-Mill Rolls Emishini Yokugoqa: Insimbi Ehlanganisiwe, Insimbi Ehlanganisiwe kanye Nensimbi Ehlanganisiwe Ene-Chromium Eningi
Ama-roll okugaya ayizingxenye eziyinhloko ezithwala umthwalo omningi ezifakwe ngaphakathi kwezindlu zokugaya, ezifakwe izintambo zokugaya ukuze kuxhunywe idrayivu.
Izinto zokwakha:Insimbi eyakhiwe, insimbi ehlanganisiwe, insimbi ehlanganisiwe ene-chromium ephezulu, insimbi esheshayo. Ama-roll agugile angabuyiselwa ngokufakwa kwe-hardfacing.
Umsebenzi:Faka amandla okugoqa kuma-billets ensimbi nasemapuletini ukuze ufeze ukuguqulwa kwensimbi ngepulasitiki, ukunciphisa ukujiya kanye nokwakheka kwephrofayili. Uma imithwalo esindayo igoqa, ukucindezeleka komthelela kanye nokukhathala kokushisa.
Ama-Conveyor Roll (Ama-Table Rolls / Ama-Pinch Rolls)
Ama-conveyor roll ahlelwe phezulu nangezansi kwama-rolling mills. Awahlanganyeli ekuguqulweni kwensimbi, kodwa enza ukuthuthwa kwezinto; ama-pinch rolls aphinde ahlinzeke ngokubamba imicu. Angafakwa njengamayunithi angawodwa noma ahlanganiswe ngamabili ngaphakathi kwezindawo zokugoqa imiqulu.
Izinto zokwakha:Insimbi eyenziwe nge-alloy. Izindawo ezigoqekayo zingaqiniswa ukuze zingagugi; isakhiwo esipholile ngamanzi siyatholakala ukuze sisetshenziswe emazingeni okushisa aphezulu.
Umsebenzi:Dlulisa ama-billets ensimbi namapuleti. Imigqa yokubamba egoqekayo ukuze ivumele ukudla kanye nokulawula ukucindezeleka. Ingaguguleka kakhulu futhi iguguleke ngenxa yokushisa okuphezulu.
Imininingwane kanye Nezimo Zesevisi Ezijwayelekile
Ama-Mill Roll
1. Usayizi ophakathi nendawo omncane φ200-450 mm:Kwezingxenye ezigoqekayo, imigoqo kanye namapuleti amancane/aphakathi. Imelana nomthelela ophakathi; indawo yokugoqeka ifanele ukuqina okuphindaphindiwe kanye nokugaya kabusha. Isetshenziswa ezigayweni zensimbi ezincane neziphakathi, ezigayweni zezingxenye kanye nasezindaweni zokusebenzela zokugoqeka zensimbi ezingenayo i-ferrous.
2. Isisindo esinzima φ450-850 mm:Kumapuleti asindayo aguqiwe ngokushisa, imichilo ebanzi kanye nezingxenye ezinkulu. Amandla okuguqiswa aphezulu kanye nokushaqeka kokushisa okujikelezayo, okudinga ubulukhuni obuphezulu bendawo kanye nokumelana nokukhathala kokushisa. Kusetshenziswa kabanzi ezindaweni ezinkulu neziphakathi nendawo zokulungisa ama-roll.
3. Okukhethekile okukhulu kakhulu φ850-1300 mm:Ukwephulwa kwepuleti elisindayo kanye ne-billet enkulu egoqayo emigqeni eqhubekayo yokugoqa. Imithwalo ephezulu kakhulu; izidingo eziqinile zekhwalithi yokubumba, ukujula kwezingqimba eziqinile kanye nokuhlolwa okungonakalisi. Kusetshenziswa kubakhiqizi bensimbi abaphambili kanye nezisekelo zokukhiqiza amapuleti anzima.
4. Usayizi omncane wokunemba φ80-180 mm:Isetshenziselwa ukugoqa okubandayo okulula, i-copper/aluminium foil kanye nokugoqa okune-thin-plate eqondile. Isidingo sokuqeda okuphezulu; hhayi ukugoqa okushisayo okunzima.
Ama-Conveyor Roll
1. Umsebenzi olula φ80-140 mm:Ukuthuthwa okusheshayo kwamapuleti amancane nama-billet amancane amatafula okupholisa nezingxenye zokulethwa. Umthwalo olula, ukujikeleza okubushelelezi. Kufanelekela imigqa yokukhiqiza yesigaba esincane nesiphakathi nendawo kanye nepuleti.
2. Inhloso ejwayelekile φ140-280 mm:Thutha amapuleti aphakathi kuya kwasindayo kanye nama-billet ahlanganisiwe. Ingasetshenziswa njengemiqulu yetafula yokungena/yokuphuma esithandweni noma imiqulu yokuncinza. Melana nokuguguleka okuphakathi kanye nokuguguleka kwesikali; ukuguquguquka okuphezulu kakhulu. Yamukelwa abakhiqizi bemishini yensimbi kanye nabaphakeli bezingxenye ezisele.
3. Ukushisa okuphezulu okunzima φ280-450 mm:Thutha ama-billet ashisayo ezindaweni zokulahla eziqhubekayo. Ukusebenza okuqhubekayo kwemithwalo esindayo ngaphansi kokushisa okuphezulu kanye nokuguguleka kwesikali. Inketho epholile ngamanzi iyatholakala ezimweni ezinzima. Isetshenziswa emigqeni ehlanganisiwe yokugoqa eqhubekayo yokugoqa eshisayo kanye nemishini emikhulu yokugoqa eshisayo.
4. I-Miniature φ50-75 mm:Kwezintambo zamafilimu namapuleti embonini yokukhanya. Umthwalo ophansi, ukumelana okulinganiselwe kokushisa okuphezulu; akufaneleki isevisi yensimbi esindayo.

Okuvelele Komkhiqizo
Ama-roll okugaya ayizingxenye ezibalulekile ezithwala umthwalo ezidinga amandla aphezulu omzimba ogoqa kanye nesendlalelo esiqinile esijulile, esisekela ukugaya kabusha kanye nokwakhiwa kabusha kwe-hardfacing. Ama-roll okuhambisa agxila ekusebenzeni kokujikeleza, ukumelana nokuguguleka kanye nokubekezelela izinga lokushisa eliphezulu. Ukwenziwa ngokwezifiso kuyatholakala ngokwemidwebo yamakhasimende yazo zombili izinhlobo zama-roll.
