Izigayo ezishisayozibalulekile ekukhiqizeni izinhlobonhlobo zezinsimbi nama-alloys ezimbonini ezihlukahlukene njengezezimoto, i-aerospace kanye nezokwakha.Izinga lomkhiqizo wokugcina lincike kakhulu ekusebenzeni komsebenzi kanyeama-back-up rolls esetshenziswa enqubweni yokugoqa eshisayo.Kule bhulogi, sizoxoxa ngokubaluleka kokusebenzisa amaroli ekhwalithi ephezulu ezigayweni ezishisayo.

Imiqulu yomsebenzi angamathuluzi ayinhloko asetshenziselwa ukukhubaza nokulolonga into egoqwayo.Zihlala zingaphansi kwamazinga okushisa aphezulu, ukucindezela okukhulu kanye nokungqubuzana phakathi nenqubo yokushisa eshisayo.Ngakho-ke, kubalulekile ukusebenzisa ama-work rolls ekhwalithi ephezulu enziwe ngezinto ezikwazi ukumelana nalezi zimo ezinzima ngaphandle kokuphazamisa ukusebenza kwawo nokuphila isikhathi eside.Amaroli omsebenzi wekhwalithi ephezulu awagcini nje ngokuqinisekisa ukwakheka kwezinto ezibonakalayo nokunemba, futhi anciphisa ubungozi bokuhluleka kwamaroli kanye nesikhathi sokuphumula esibizayo.

I-backup rolls, ngakolunye uhlangothi, isekela ama-rolls omsebenzi futhi isiza ukugcina ukwakheka nokushuba kwezinto ezigoqwayo.Njengemiqulu yomsebenzi, ama-backup rolls avezwa emazingeni okushisa aphezulu kanye nezingcindezi, futhi ikhwalithi yawo iba yisici esibalulekile ekusebenzeni kahle okuphelele nokunemba kwenqubo yokugoqa okushisayo.Ukusebenzisa ama-backup rolls ekhwalithi ephezulu kuqinisekisa ukusekelwa okufanele kwama-work rolls, kunciphisa ukuwohloka kwezinto, futhi kunomthelela ekuthembekeni kukonke kanye nokuvumelana kwesigayo.

Kafushane, ukutshala imali kuma-rolls ekhwalithi ephezulu, okuhlanganisa ama-work rolls nama-backup rolls, kubalulekile ekusebenzeni kahle nangempumelelo kwesigayo esishisayo.Abakhiqizi nabakhiqizi kufanele babeke phambili ikhwalithi ye-roll nokuqina ukuze baqinisekise umkhiqizo oqediwe wekhwalithi ephezulu.Ngokukhetha amaroli alungile nokuyigcina ngendlela efanele, izinkampani zinganciphisa isikhathi sokuphumula, zinciphise izindleko zokunakekela, futhi ekugcineni zikhuphule ukusebenza okuphelele nokukhishwa kwezigayo zazo ezishisayo.
