umbhobho steel stainless yintsimbi ende umngxuma ngeenxa zonke, nto leyo isetyenziswa ngokubanzi kwi-petroleum, imichiza, unyango, ukutya, ishishini ukukhanya, oomatshini kunye instrumentation, kunye neminye imibhobho zoshishino kunye neenxalenye zesakhiwo oomatshini. Ngaphandle koko, xa ukugoba kunye namandla e-torsion kufana, ubunzima bulula, ngoko busetyenziswa ngokubanzi ekwenzeni iinxalenye zoomatshini kunye nezakhiwo zobunjineli. Ikwasetyenziswa rhoqo ukwenza izixhobo eziqhelekileyo ezahlukeneyo, imigqomo kunye namaqokobhe.

1. Ukugxila
Inkqubo yokuvelisa imibhobho engenamthungo kukubetha umngxuma kwi-billet yensimbi engenasici kwiqondo lokushisa elingu-2200 ° f. Kobu bushushu buphezulu, isixhobo sentsimbi siyathambile kwaye senziwa ngokujikelezayo ukusuka emngxunyeni emva kokubetha kunye nokuzoba. Ngale ndlela, ubukhulu bodonga lombhobho abulingani kwaye i-eccentricity iphezulu. Ke ngoko, i-ASTM ivumela umahluko wobungakanani bodonga lwemibhobho engenamthungo ukuba ube mkhulu kunombhobho othungelweyo. Umbhobho otyunjiweyo wenziwa kwiphepha elichanekileyo elipholileyo elibandayo (elinobubanzi beenyawo ezi-4-5 ngekhoyili nganye). La maphepha aqengqelekayo abandayo ahlala anomahluko wobukhulu bodonga oluyi-0.002 intshi. Isitya sensimbi sinqunywe kububanzi be-πd, apho d ububanzi bangaphandle bombhobho. Ukunyamezela kobunzima bodonga lombhobho we-slit buncinci kakhulu, kwaye ubuninzi bodonga bufana kakhulu kwi-circumference.

2. Ukuwelda
Ngokuqhelekileyo, kukho umahluko othile ekubunjweni kweekhemikhali phakathi kwemibhobho edibeneyo kunye nemibhobho engenamthungo. Ukubunjwa kwensimbi yokuvelisa imibhobho engenamthungo kuphela imfuno esisiseko ye-ASTM. Intsimbi esetyenziselwa ukuvelisa imibhobho edibeneyo iqulethe izinto zekhemikhali ezifanelekileyo kwi-welding. Ngokomzekelo, ukuxuba izinto ezifana ne-silicon, isulfure, i-manganese, i-oksijini, kunye ne-ferrite ye-triangular kwinqanaba elithile kunokuvelisa i-weld melt ekulula ukuhambisa ubushushu ngexesha lenkqubo ye-welding, ukuze i-weld yonke ingene. Imibhobho yensimbi engenalo ukwakheka kweekhemikhali ezingentla, njengemibhobho engenamthungo, iya kuvelisa izinto ezahlukeneyo ezingazinzanga ngexesha lenkqubo ye-welding kwaye akulula ukuyidibanisa ngokuqinileyo kwaye ingaphelelanga.

3. Iisayizi zeenkozo
Ubungakanani obuziinkozo bentsimbi bunxulumene nobushushu bonyango lobushushu kunye nexesha lokugcina ubushushu obufanayo. Ubungakanani obuziinkozo betyhubhu yentsimbi engenamthungo kunye netyhubhu yentsimbi engenamthungo iyafana. Ukuba umbhobho we-seam wamkela unyango oluncinci olubandayo, ubungakanani beenkozo ze-weld buncinci kunobukhulu beenkozo zetsimbi edibeneyo, ngaphandle koko, ubukhulu bengqolowa bufana.
