Ngokombono wokwakheka kwezinto ezibonakalayo, imiqulu ye-carbide enosimende ilungiswa ikakhulukazi inqubo ye-powder metallurgy ngenqubo ye-powder metallurgy ngokusebenzisa izinhlanganisela zensimbi eziphikisayo (njenge-tungsten carbide WC, i-titanium carbide TiC, njll.) njenge-matrix, nezinsimbi eziguqukayo (njenge i-cobalt Co, i-nickel Ni, njll.) njengesigaba sokuhlanganisa. Le nhlanganisela ekhethekile yezinto inika ama-tungsten carbide rolls izinga eliphezulu lobulukhuni, ukumelana nokugqoka kanye nokumelana nokukhathala okushisayo, okubenza bakwazi ukumelana nokuguga okujulile nokuklebhuka kwezinga lokushisa eliphezulu, ingcindezi ephezulu kanye nezinqubo zokugingqa ngesivinini esikhulu. I-ceramic roll isekelwe ezintweni ze-ceramic futhi icutshungulwe ngenqubo ekhethekile. Izinto ze-ceramic ngokwazo zinobulukhuni obuphezulu kakhulu kanye nokumelana nokugqwala okuhle kakhulu, okwenza i-ceramic roll isebenze kahle enqubweni yokugoqa, ikakhulukazi esimweni sezidingo eziphakeme zokuqeda phezulu kanye nokumelana nokugqwala komqulu.
Ngokuya ngezici zokusebenza, ama-tungsten carbide rolls ayaziwa ngokumelana kwawo nokugqoka kanye nokumelana nokukhathala okushisayo. Inobunzima obuphezulu kanye nokuzinza okuhle kokushisa, futhi ingagijima ngokuzinza isikhathi eside endaweni enezinga eliphezulu lokushisa kanye nemithwalo ephezulu, okuthuthukisa kakhulu ukusebenza kahle kwesigayo. Ngaphezu kwalokho, ama-tungsten carbide rolls nawo ane-conductivity enhle yokushisa, engasusa ngokushesha ukushisa okukhiqizwa phakathi nenqubo yokugoqa, inciphise izinga lokushisa elingaphezulu lemiqulu, futhi inciphise ukulimala kokucindezeleka okushisayo kuma-rolls. Imiqulu ye-Ceramic, ngakolunye uhlangothi, ibonakala ngobulukhuni bayo obukhulu, ukumelana nokugqwala kanye nokuzinza okuphezulu kwezinga lokushisa. Izakhiwo ezikhethekile zezinto ze-ceramic zenza imiqulu ye-ceramic ingabi lula ukuchithwa ngamakhemikhali ngesikhathi senqubo yokugoqa, futhi ingagcina ukuphela nokunemba kwe-roll surface isikhathi eside. Ngesikhathi esifanayo, ama-ceramic rolls angakwazi ukugcina ukusebenza okuzinzile ezindaweni ezishisa kakhulu, futhi ngeke akhubaze noma athambe ngenxa yokwanda kwezinga lokushisa.
Ngokwesicelo, imiqulu ye-carbide enosimende isetshenziswa kakhulu ekukhiqizeni insimbi, izinsimbi ezingenayo insimbi, izinto ze-alloy nezinye izimboni ngenxa yezakhiwo zabo ezinhle kakhulu. Ikakhulukazi ezindaweni eziginqikayo ezinamandla amakhulu, ezinomthwalo omkhulu njengezigayo zokugingqa zezintambo ezinesivinini esikhulu kanye nezigayo zokuphothula, amaroli e-carbide anosimende adlala indima engenakushintshwa. Imiqulu ye-Ceramic isetshenziswa kakhulu emigqeni yokukhiqiza eshisayo nebandayo embonini yensimbi, ukukhiqizwa kwe-ceramic, ukucubungula ingilazi kanye nemboni ye-electronics ngenxa yokuqina kwayo okuphezulu, ukumelana nokugqwala kanye nokuzinza okuphezulu kwezinga lokushisa.
