IiMill Rolls zeRolling Mills: Intsimbi eyenziweyo, iCast Steel kunye neHigh-Chromium Cast Iron
Iiroli zeMill zizinto eziphambili ezinomthwalo omninzi ezifakwe ngaphakathi kwezindlu zeMill, zixhotyiswe ngeentamo zemill ukuze ziqhagamshele kwidrive.
Izixhobo:Intsimbi eqiniweyo, intsimbi eqinisiweyo, intsimbi eqinisiweyo ene-chromium ephezulu, intsimbi ekhawulezayo. Iiroli ezigugileyo zingabuyiselwa nge-hardfacing.
Umsebenzi:Faka amandla okuqengqeleka kwiibhilethi zentsimbi kunye neepleyiti ukuze ufezekise ukuguquka kwesinyithi ngeplastiki, ukunciphisa ubukhulu kunye nokwenziwa kweprofayili. Xa imithwalo enzima yokuqengqeleka, uxinzelelo lwempembelelo kunye nokudinwa kobushushu.
IiRoli zoThutho (IiRoli zeTafile / iiRoli zePinch)
Iiroli zokuhambisa zicwangciswe phezulu nasezantsi kweeroli. Azibandakanyeki ekuguqulweni kwesinyithi, kodwa zithutha izinto; iiroli zokufaka i-pinch zikwabonelela ngokubamba imicu. Zingafakwa njengeeyunithi ezizimeleyo okanye zidityaniswe ngababini ngaphakathi kweendawo zokufaka imiqulu.
Izixhobo:Intsimbi ye-alloy eyenziweyo. Imiphezulu yeeroli inokuqina ukuze ingagugi; isakhiwo esipholileyo ngamanzi siyafumaneka ukuze sisebenze kubushushu obuphezulu.
Umsebenzi:Dlulisa iibhilethi zentsimbi kunye neepleyiti. I-Pinch rolls grip strips ukuze ikwazi ukulawula ukutya kunye noxinzelelo. Ingagugiswa kwaye ikhukuliseke ngenxa yobushushu obuphezulu.

Isetyenziswa kubavelisi abaphambili bentsimbi kunye neziseko zemveliso yepleyiti enzima.
4. Ubungakanani obuncinci obuchanekileyo φ80-180 mm:Isetyenziselwa ukuqengqeleka okubandayo kancinci, ifoyile yekopolo/yealuminiyam kunye nokuqengqeleka okucokisekileyo kwepleyiti encinci. Imfuneko yokugqiba umphezulu ophezulu; ayisetyenziselwa ukuqengqeleka okushushu okunzima.
Iiroli zokuhambisa
1. Umsebenzi olula φ80-140 mm:Ukuhanjiswa ngokukhawuleza kweepleyiti ezibhityileyo kunye neebhilethi ezincinci zeetafile zokupholisa kunye namacandelo okuhambisa. Umthwalo olula, ukujikeleza okugudileyo. Ifanelekile kwimigca yemveliso yecandelo elincinci neliphakathi kunye neepleyiti.
2. I-Jikelele-yenjongo φ140-280 mm:Thutha iipleyiti eziphakathi ukuya kwezinzima kunye neebhilethi ze-cast. Ingasetyenziswa njengee-furnace/exit table rolls okanye ii-pinch rolls. Ixhathise ukukhukuliseka okuphakathi kunye nokukhula kwesikali; isebenziseka lula kakhulu. Yamkelwe ngabavelisi bezixhobo zesinyithi kunye nababoneleli bezixhobo ezingasetyenziswayo.
3. Ubushushu obuphezulu obuphezulu obuphezulu φ280-450 mm:Ukuthutha ii-billets ezishushu kakhulu kwiindawo zokulahla eziqhubekayo. Ukusebenza rhoqo komthwalo onzima phantsi kobushushu obuphezulu kunye nokukhukuliseka kwesikali. Ukhetho olupholisiweyo ngamanzi luyafumaneka kwiimeko ezinzima. Lusetyenziswa kwimigca edibeneyo yokulahla eshushu kunye nee-hot rolling mills kunye nee-hot rolling mills ezinkulu.
4. I-Miniature φ50-75 mm:Kwimigca yefilimu kunye neepleyiti zeshishini lokukhanya. Umthwalo ophantsi, ukumelana okuncinci kobushushu obuphezulu; ayifanelekanga kwinkonzo enzima yesinyithi.
