Ukuqina kobuso nokufana kweama-shaft forgingsizinto eziyinhloko zezidingo zobuchwepheshe kanye nokuhlolwa okujwayelekile. Ubulukhuni bomzimba bukhombisa ukumelana nokugqokwa, njll., ekukhiqizeni, ugu lokuqina D lobunzima be-HSd lusetshenziselwa ukuveza.
Izidingo zokuqina kokuqina kwe-shaft forgings ngokuyinhloko zisekelwe ezingeni lobulukhuni berola esebenzayo noma i-roller ephakathi lapho ithintana nayo, futhi okubili kufanele kugcine ubudlelwano obufanele bokuhambisana. Ngokocwaningo lomshini wokukhathala othintana naye, ubulukhuni berola yokusekela kufanele bube ngamayunithi angu-10-25 HS aphansi kunaleyo yengxenye yokuxhumana, okuzuzisa ukuthuthukisa isimo sokukhathala endaweni yokuxhumana. Kunzimaama-shaft forgingsbabe nokumelana nokugqoka okuphansi futhi bathambekele ekwenzeni "i-peeling", okungukuthi, ungqimba olungajulile lwe-roll surface lukhiqiza ukuguqulwa kwepulasitiki bese kukhiqiza ukucwenga okuncane; Uma ubulukhuni buphezulu kakhulu, amathuba okuba i-brittle spalling ayanda. Njengoba inani lokuqina lokuphuka kwesendlalelo esiqinile liphansi, uma ukuqhekeka sekuvela, kuzosabalala ngokushesha, okuholela ekuchithekeni okukhulu kwenqwaba. Ukuqina okuphezulu nakho kungabangela ukulimala kokukhathala kokuxhumana kanye nokuguga okusheshayo kweama-shaft forgingsfuthi unciphise isikhathi sokugayaama-shaft forgings.

Eminyakeni yamuva, ubulukhuni beama-shaft forgingsyesigayo esibandayo nesishisayo senziwe ngcono ngokujwayelekile, ikakhulukazi amaroli omsebenzi wesigayo esigoqayo athuthukisiwe futhi athuthukiswa ngokulandelana, izinga lokuqina lamaroli ensimbi ahlanganisiwe e-chromium eyi-centrifugal ephezulu, amaroli ensimbi ayi-centrifugal ephezulu ne-alloy ephezulu engakhawulelwe. imiqulu yensimbi. Izinga lobulukhuni beama-shaft forgingsisifinyelele ku-70-83. Izinto zamanje zokubumba i-shaft kanye nobuchwepheshe bokukhiqiza zingahlangabezana nobunzima be-55-75 enkulu yekhwalithi ephezulu ye-shaft forgings. Ngaso leso sikhathi, ukusetshenziswa kwe-high hardness shaft forging maintenance technology nakho kuqongelele ulwazi oluningi.
Okukhuluama-shaft forgings amakhuluyesigayo samapuleti makhulu ngosayizi futhi asindayo ngesisindo, futhi isivinini sokuginqika sincane kakhulu kunesomshini wokugaya. Ngakho-ke, izidingo zokumelana nokugqoka kanye nobulukhuni nazo ziphansi.
