Ubulukhuni obuphezulu be-Tungsten Carbide Roller Ring ye-High Speed ​​Rolling yama-alloy Steel Bars

Izindandatho ze-Carbide roller zazalwa nokuthuthukiswa kwemboni yokucubungula insimbi ngemva kokufika kobuchwepheshe be-powder metallurgy ngo-1909. Selokhu kwethulwa umdwebo we-carbide wire drawing eshona eJalimane ngo-1918, uye wagqugquzela ucwaningo nge-carbide enosimende emazweni ahlukahlukene, kanye nemiqulu. ngezinhloso ezehlukene futhi ziye zavela enye ngemva kwenye.Kodwa-ke, ukusetshenziswa okukhulu kwamarola e-carbide anosimende kwenzeka ngemva kuka-1960. Ngo-1964, ukuzalwa komshini wokuqala wokugaya i-twist-free wire rod we-Morgen Company wenyusa isivinini sokuqeda izikhathi ezingu-4.Njengoba iyunithi yokugaya yokuphothula isebenza ngesivinini esikhulu kanye nokucindezeleka okukhulu, ama-roller ensimbi kanye nama-roller ensimbi amathuluzi anokumelana nokugqokwa okungalungile, impilo ye-rolling groove ifushane, futhi ukulungiswa nokulayisha nokulayishwa kwemiqulu kuvame kakhulu, okuthinta ukusebenza kahle komshini wokugaywa futhi akusafanele ukuqedela ukukhiqiza.izidingo, ngakho-ke kwathathelwa indawo ama-roller e-carbide ahlanganisiwe.Kukhona izigayo zezimpande ezingaphezu kuka-200 emhlabeni, ezidla amakhulukhulu amathani e-carbide eginqikayo minyaka yonke.
