Izinto zale nxalenye yobuxoki:
I-14CrNi3MoV (921D), ifanelekile kwi-forgings yensimbi enobunzima obungadlulanga i-130mm esetyenziswa kwiinqanawa.
Inkqubo yokwenziwa kwemveliso:
Intsimbi ekhandiweyo kufuneka inyibilikiswe ngokusebenzisa isithando sombane kunye nendlela yokucima i-slag yombane, okanye ezinye iindlela ezivunyiweyo kwicala lemfuno. Intsimbi kufuneka ifumane i-deoxidation eyaneleyo kunye neenkqubo zokucocwa kweenkozo. Xa uqulunqa ingot ngokuthe ngqo kwinxalenye edibeneyo, umlinganiselo wokubumba womzimba oyintloko wecandelo kufuneka ube ngaphantsi kwe-3.0. Umlinganiselo wokubunjwa kweendawo ezicwecwe, iiflange, kunye namanye amacandelo awandisiweyo ecandelo elibunjiweyo kufuneka libe ngaphantsi kwe-1.5. Xa uqulunqa i-billet kwi-forged part, umlinganiselo wokubunjwa womzimba oyintloko wecandelo kufuneka ube ngaphantsi kwe-1.5, kwaye umlinganiselo wokubunjwa kweengxenye eziphumayo kufuneka ube ngaphantsi kwe-1.3. Iindawo ezibunjiweyo ezenziwe kwiingots okanye iibhilithi ezibunjiweyo kufuneka zifumane i-dehydrogenation eyaneleyo kunye nonyango lwe-annealing. I-Welding yeebhilidi zetsimbi ezisetyenziselwa ukuvelisa iindawo ezibunjiweyo azivumelekanga.
Imeko yohambiso:
Inxalenye ephothiweyo kufuneka ihanjiswe kwimeko ecinyiweyo kunye neyomsindo emva kokulungiswa kwangaphambili konyango. Inkqubo ecetyiswayo yi (890-910) ° C normalizing + (860-880) ° C quenching + (620-630) ° C tempering. Ukuba ubukhulu becala elibunjiweyo bungaphezulu kwe-130mm, kufuneka buhlaziywe emva kokwenziwa ngokurhabaxa. Iindawo ezipholileyo ezibunjiweyo akufuneki zingene kwisiqabu soxinzelelo ngaphandle kwemvume yecala lemfuno.
Iimpawu zoomatshini:
Emva kokuba unyango olushushu, iimpawu zomatshini zecandelo elibunjiweyo kufuneka lihambelane neenkcukacha ezifanelekileyo. Ubuncinci iimvavanyo zempembelelo kumaqondo obushushu e -20°C, -40°C, -60°C, -80°C, kunye -100°C kufuneka zenziwe, kwaye ifuthe elipheleleyo lamagophe obushushu bamandla kufuneka licetywe.
Ukubandakanywa okungeyontsimbi kunye nobukhulu beenkozo:
Amalungu abunjiweyo enziwe kwiingots kufuneka abe nomlinganiselo wobungakanani benkozo hayi ngaphezulu kwe-5.0. Inqanaba lokufakwa kohlobo lwe-A kwintsimbi akufanele lidlule i-1.5, kwaye inqanaba lokufakwa kohlobo lwe-R akufanele lidlule i-2.5, kunye nenani lezo zombini ezingadluli kwi-3.5.
Umgangatho womphezulu:
Amalungu abunjiweyo akufuneki abe neziphene ezibonakalayo ezinjengokuqhekeka, ukugoba, imingxunya ecuthekileyo, izivubeko, okanye indibaniselwano yangaphandle engeyiyo eyentsimbi. Iziphene zobuso zinokulungiswa ngokusebenzisa ukukrala, ukutshiza, ukugaya ngevili lokusila, okanye iindlela zomatshini, ukuqinisekisa isibonelelo esaneleyo sokugqiba emva kokulungiswa.
