Microstructure ndi Properties of Hot-rolled Seamless

Pakali pano, opanga zitsulo zoweta amakumana ndi zovuta zazikulu zowonongeka kwazitsulo zosasunthika, ziyenera kusintha kapangidwe ka mankhwala, kuthetsa mphamvu zopanga zobwerera m'mbuyo ndi kafukufuku ndi chitukuko cha mankhwala apamwamba.Kafukufuku woyeserera wasonyeza: kukhazikitsidwa kwa kuwongolera kuziziritsa kumatha kuyendetsedwa njira zosinthira gawo, kuwongolera tirigu, motero kuwongolera zida zamakina akupanga chitoliro chopanda chitsulo chosasinthika munjira yozizira.Choncho, kuphunzira kusintha microstructure ndi katundu zitsulo pansi osiyana kuzirala dongosolo pambuyo otentha anagubuduza osataya chitsulo chitoliro kunyamula tanthauzo lalikulu ndi mtengo.Chifukwa cha chitoliro chachitsulo chosasunthika chokhala ndi miyeso yokulirapo ndi mawonekedwe ake akuwonetsa kukula kwa kusinthaku, kupangitsa kuti pakhale kuwongolera ndi kukhazikitsa chithandizo cha kutentha kwapaintaneti komwe kumakumana ndi mitundu yambiri, monga momwe ukadaulo woziziritsira umathandizira ndikugwiritsa ntchito kupanga chitsulo chosasunthika. payipi yatsekedwa kwambiri.

Kuti tikwaniritse njira yopangira chitoliro chosasunthika munjira yoziziritsa (minus) yolamulidwa pambuyo powongoka pamaso pa bungwe lofufuza zamakina a chitoliro chachitsulo pakusintha kwa 20 kwa njira yozizirira pambuyo pogubuduza ndi kayeseleledwe ka manambala.Choyamba, Njira Yoyesera Yodziwira zitsulo zopendekera kutentha kwapakati pazikhalidwe zosiyanasiyana zozizirira, kuwerengera ubale pakati pa chitsulo chofufuzira kuzirala kwa kutentha kwapakati ndi kutentha kwa workpiece molingana ndi mfundo zazikulu za njira yotsutsa kutentha.Kenako, pogwiritsa ntchito malire kusiyana njira kukhazikitsa zitsulo kuzirala kutentha kumunda, gawo kusintha ndi mphamvu akhoza kulosera ntchito dongosolo, kusanthula boma la bungwe ndi katundu makina pansi pa mikhalidwe yosiyanasiyana ya kuzirala machubu.Pomaliza, mayeso kusanthula zitsulo mpweya kuzirala, deta kutentha anayeza pa nthawi zosiyanasiyana ndi katundu makina a zitsulo ozizira, zotsatira mawerengedwe akugwirizana bwino deta anayeza.Zotsatira zimatha kukwaniritsa machubu opanda zitsulo olamulidwa ndi kuziziritsa kuti apereke deta yoyambira.
