Ukuqina komphezulu kunye nokufana kwei-shaft forgingszizinto eziphambili zeemfuno zobugcisa kunye nokuhlolwa kwesiqhelo. Ubunzima bomzimba bubonisa ukuxhathisa ukunxiba, njl., kwimveliso, unxweme lokuqina D ubunzima bexabiso le-HSd lisetyenziselwa ukuvakalisa.
Iimfuno zobulukhuni be-shaft forgings zisekelwe ikakhulu kwinqanaba lobulukhuni be-roller yokusebenza okanye i-roller ephakathi ekudibaneni nayo, kwaye ezi zimbini kufuneka zigcine ubudlelwane obufanelekileyo bokuhambelana. Ngokophando kwindlela yokudinwa koqhagamshelwano, ubunzima be-roller yenkxaso kufuneka ibe yiyunithi ye-10-25 ye-HS ephantsi kunecandelo loqhagamshelwano, olunenzuzo ekuphuculeni into yokukhathala kwindawo yoqhagamshelwano. Kunzimai-shaft forgingsbanokunganyangeki okuncinci kwaye bathambekele kwi-"peeling" isenzeko, oko kukuthi, umaleko ongekho nzulu we-roll surface uvelisa i-deformation yeplastiki kwaye emva koko ivelise ukuxobulwa komhlaba omncinci; Xa ubulukhuni buphezulu kakhulu, amathuba okuba ne-brittle spalling ayanda. Njengoko ixabiso lokuqina kwesambuku somaleko oqinileyo lisezantsi, nje ukuba kubonakale ukuqhekeka, kuya kusasazeka ngokukhawuleza, okukhokelela kuqhekeko olukhulu. Ubunzima obuphezulu bunokubangela umonakalo wokudinwa koqhagamshelwano kunye nokukhawuleza ukugugai-shaft forgingskwaye unciphise ixesha lokusila lei-shaft forgings.

Kwiminyaka yakutshanje, ubunzima bei-shaft forgingsIlitye lokusila elibandayo nelishushu liphuculwe ngokubanzi, ingakumbi iiroli zokusebenza zelitye lokusila elishushu ziye zaphuhliswa kwaye zakhuthazwa ngokulandelelanayo, umgangatho wobulukhuni be-centrifugal composite high chromium cast iron rolls, centrifugal composite high chromium rolls zentsimbi kunye nealloyi ephezulu engathintelwanga. imiqulu yentsimbi. Inqanaba lobulukhuni bei-shaft forgingsifikelele kuma-70-83. Izixhobo zangoku zokubumba i-shaft kunye neteknoloji yokuvelisa inokuhlangabezana nobunzima be-55-75 enkulu yomgangatho ophezulu we-shaft forgings. Kwangaxeshanye, ukusetyenziswa kobulukhuni obuphezulu be-shaft yokwenza itekhnoloji yogcino nako kuqokelele amava amaninzi.
Eyona superiifologi ezinkulu zeshaftIlitye lokusila likhulu ngokobukhulu kwaye linzima ngobunzima, kwaye isantya sokuqengqeleka sincinci kakhulu kuneso sokusila. Ke ngoko, iimfuno zokunxiba kunye nobunzima nazo ziphantsi.
