Andazi ukuba uqaphela kangakanani na umbhobho wentsimbi ongenamthungo? Iityhubhu zentsimbi ezingenamthungo zisetyhula, isikwere kunye noxande kunye necandelo lemibhobho yentsimbi engenanto ngaphandle kwamalungu angaphandle. Ityhubhu yentsimbi engenamthungo yenziwe nge-ingot yentsimbi okanye ibhayibhile yetyhubhu eqinileyo ngokugqobhoza kwityhubhu ye-capillary. yenziwa ngokuqengqeleka okushushu, ukuqengqeleka okubandayo okanye umzobo obandayo. Iityhubhu zentsimbi ezingenamthungo zineziqendu ezingenanto kwaye zihlala zisetyenziswa njengemibhobho yokuthutha ulwelo. badinga ukugoba okufanayo kunye nokomelela okujikelezayo kwaye bakhaphukhaphu kunentsimbi eqinileyo njengentsimbi engqukuva. bayintsimbi yecandelo lomnqamlezo olunoqoqosho kwaye baqeshwe ngokubanzi ekwenziweni kwezakhiwo, iinxalenye kunye namalungu oomatshini, okufana nesikafula sentsimbi esisetyenziselwa ukomba ioyile.
Kwinkqubo yombhobho yentsimbi engenamthungo, kukho amanyathelo amaninzi okufumana imibhobho enomgangatho oyintloko. Isakhiwo se-metallographic esanelisayo sifumaneka ngokususa umsebenzi wokuqina kweetyhubhu zetsimbi ezingenamthungo. Isixhobo senkqubo sisithando somlilo esikhanyayo, esisetyenziswa kakhulu. Intsimbi ye-chrome egqityiweyo iphathwa ukushisa kwindawo ekhusela kakhulu. Xa ukusebenza kwesixhobo sombhobho wentsimbi engenamthungo kwahlukile, ulwakhiwo lwe-metallographic emva kokufakwa kwe-annealing eqaqambileyo, ngoko ke inkqubo yonyango lobushushu obuqaqambileyo iya kwahluka.
Emva kokusebenza okubandayo, uxinzelelo olushiyekileyo lwembhobho yensimbi engenamthungo luhlala luhleli, kwaye ke ngoko uxinzelelo olushiyekileyo luyinto engathandekiyo kakhulu kuhlobo lokuqhekeka kwe-corrosion yombhobho. Naliphi na iqondo lomsebenzi obandayo likhokelela ekwandeni okukhulu koxinzelelo lwe-corrosion cracking resistance. Umgangatho wokusebenza okubandayo ukwanefuthe elibi ekuxhathiseni ubushushu obushushu bentsimbi ye-austenitic. Ngokubanzi, iqondo eliphezulu lobushushu bokusebenza okanye umphezulu iimfuno zobomi bokwaphuka, kokukhona kusezantsi iqondo lokusetyenzwa kwengqele.
Njengoko kunokubonwa kwintshayelelo engentla, inkqubo yokufudumala yobushushu bombhobho wentsimbi engenamthungo luhlobo oluyinkathazo. ukuze ufumane ulwakhiwo olufanelekileyo lwe-metallographic, uhlengahlengiso inxalenye yecandelo lokupholisa izixhobo zesithando somlilo esiqaqambileyo kufuneka sibe sikhulu. Ke ngoko, isithando somlilo esiqaqambileyo esiphucukileyo sihlala samkela ukupholisa okuqinileyo kwicandelo laso lokupholisa, kwaye sinamacandelo amathathu okupholisa, anokulungelelanisa umthamo womoya ngokwahlukeneyo. yohlulwe yangamacandelo amathathu ngobubanzi bomcu.
