Umbhobho wentsimbi womatshini ongenamthungo yenye yezona ntlobo zisetyenziswa ngokuqhelekileyo kwimibhobho yentsimbi engenamthungo.Umbhobho wensimbi ongenamthungo unecandelo elingenanto kwaye akukho welds ukusuka ekuqaleni ukuya ekupheleni.Xa kuthelekiswa nentsimbi eqinileyo efana nentsimbi ejikelezayo, umbhobho wentsimbi ongenamthungo unobunzima obulula xa ukugoba kunye namandla okubetha kuyafana, kwaye luhlobo lwentsimbi yecandelo loqoqosho.
Kukho iindidi ezimbini zombhobho wentsimbi womatshini ongenamthungo:
I-Cold drawn ingenamthungo (CDS) kunye ne-hot rolled seamless (HFS).Zombini iCDS kunye neHFS imibhobho yentsimbi inamandla kunye nokuqina, kodwa iingenelo zenkqubo yokwenziwa kohlobo ngalunye lombhobho zihluke kancinane.Ukugqiba malunga nokuba umbhobho obandayo otsaliweyo ongenamthungo okanye umbhobho ongenamthungo osetyenzisiweyo oshushu yeyona nto ingcono kuxhomekeke kwindlela oceba ukuwusebenzisa ngayo umbhobho kwisicelo sakho.
Ityhubhu yomatshini epholileyo etsalwa ngokungenamthungo yenziwe ngentsimbi yentsimbi yekhabhoni eyi-SAE 1018 eshushu kwaye yolulwe kwiqondo lobushushu begumbi.Ngethuba lenkqubo yokwelula, incam yombhobho idlula kwi-mold.I-force isetyenziselwa ukunweba intsimbi ukuya kubukhulu obufunekayo kunye nokumila kunye nokugudisa umphezulu.Olu hlobo lombhobho wensimbi ludibana nomgangatho we-ASTM A519.Inika amandla aphezulu esivuno, ukunyamezelana okusondeleyo kunye neendawo ezigudileyo, okwenza kube yinto yokuqala yokukhetha kwizicelo ezininzi zoomatshini.
Imibhobho yomatshini eqhelekileyo yekhabhoni yentsimbi:
I-ASTM A106 Gr.B imibhobho yentsimbi engenamthungo
I-ASTM A53 GR.B imibhobho yentsimbi engenamthungo
Izinto ezilungileyo zokubanda utsalwe ngaphandle komthungo (CDS):
Umphezulu ogqibeleleyo-ubuchule obugqwesileyo-ukwanda kokunyamezelana kwe-dimensional-high-for-to-weight ratio.Umbhobho womatshini owenziwe ngobushushu owenziwe ngobushushu uveliswa kusetyenziswa i-SEA 1026 carbon steel kwaye yenziwe kusetyenziswa inkqubo efanayo yokukhupha, kodwa akukho nyathelo lokugqibela lokudweba ityhubhu kwiqondo lokushisa.Imibhobho yentsimbi eveliswe yinkqubo ye-HFS kulula ukuyiqhuba kwaye ifanelekile kwizicelo ezingadingi ukunyamezela okungqongqo okanye ukugqitywa komphezulu ogudileyo.Umbhobho wentsimbi we-HFS udibana nomgangatho we-ASTM A519 kwaye udla ngokusetyenziswa kwizicelo ezifuna iindonga ezityebileyo nezinzima.
Izinto eziluncedo ze-thermal processed seamless (HFS):
Izinto ezinexabiso-ezilungileyo ukuqhubekeka-uluhlu olubanzi lobungakanani.Imibhobho yentsimbi yomatshini engenamthungo etsalwa ngokubanda kwaye eshushu-egqityiweyo eyenziwe yi-ASTM A519 ifumaneka kwiindidi zokumisela.
