Zvigayo zvinopisazvakakosha pakugadzirwa kwemhando dzakasiyana-siyana dzesimbi uye alloys mumaindasitiri akasiyana semotokari, aerospace uye kuvaka. Unhu hwechigadzirwa chekupedzisira hunoenderana zvikuru nekushanda kwebasa uyeback-up rolls inoshandiswa mukupisa kwekukunguruka. Mune ino blog, isu tichakurukura kukosha kwekushandisa emhando yepamusoro rolls mumagiyo anopisa anotenderedza.

Work rolls ndiwo maturusi ekutanga anoshandiswa kukanganisa uye kugadzira zvinhu zviri kukungurutswa. Ivo vanogara vachiiswa kune tembiricha yakakwira, kudzvinyirira kwakanyanya uye friction panguva yekupisa yekukungurutsa. Naizvozvo, zvakakosha kuti ushandise emhando yepamusoro dhizaini yakagadzirwa nezvinhu zvinokwanisa kumira nemamiriro ezvinhu akaomarara pasina kukanganisa kuita kwavo uye hupenyu hurefu. Yepamusoro-mhando yebasa rolls haingove nechokwadi kuenderana uye kwakanyatso kuumbwa kwezvinhu, ivo zvakare vanoderedza njodzi yekutadza kudonha uye inodhura nguva yekudonha.

Backup rolls, kune rumwe rutivi, inotsigira mipumburu yebasa uye inobatsira kuchengetedza chimiro uye ukobvu hwezvinhu zviri kukungurutswa. Kufanana nemapumburu ebasa, mipumburu yekuchengetedza inoratidzirwa kune tembiricha yakakwira uye kudzvanywa, uye hunhu hwavo hunova chinhu chakakosha mukushanda kwese uye kurongeka kweiyo inopisa rolling process. Kushandisa emhando yepamusoro backup rolls kunovimbisa kutsigirwa kwakakodzera kweiyo basa rolls, kunoderedza deformation yezvinhu, uye kunobatsira kuvimbika kwese uye kuenderana kwechigayo.

Muchidimbu, kuisa mari mumhando yepamusoro-soro, kusanganisira mabhuku ebasa uye mabhuku ekuchengetedza, zvakakosha pakushanda kwakanaka uye kwakanaka kwechigayo chinopisa. Vagadziri nevagadziri vanofanirwa kukoshesa mhando yeroll uye kusimba kuti vave nechokwadi chemhando yepamusoro chakapedzwa chigadzirwa. Nekusarudza ma rolls akakodzera uye nekuachengeta nemazvo, makambani anogona kuderedza nguva, kuderedza mari yekugadzirisa, uye pakupedzisira kuwedzera kushanda kwese uye kubuda kwezvigayo zvavo zvinopisa.
