Ukuthintela ukungakhathali

Ukuqonda kunye nokuthintela ukuvela kwe-intergran kwi-inters ye-steels yensimbi

Inkcazo ye-Meta: Funda malunga nokuntywila kwe-insosion kwi-IDDS yentsimbi engenasitali, oonobangela, iindlela zothintelo, kunye nokubaluleka konyango oluqaqambileyo. Ecpolif pictuse Umgangatho kunye nobomi obude.

Intshayelelo:

I-welding yinkqubo ebaluleke kakhulu ekungeneni kwezinto zentsimbi engenasitali, ngakumbi ekuvelisweni kwemibhobho ye-weldied. Nangona kunjalo, iziphene ze-WOLL, ngakumbi kwindawo ye-Weld, inokuchaphazela kakhulu ukuthembeka kunye nokusebenza kwemveliso yokugqibela. Omnye umcimbi ogxekayo kukungabikho kombulelo, indlela yokuhluzwa kwendawo enokukhokelela ekungathobeni kwentlekele.

Yintoni i-insosion engaqhelekanga?

I-Trasion yoThengiso phakathi kwezinto ezingenasitali ezingafunekiyo kunye nomxholo wekhabhoni ongaphezulu kwe-0.03%. Xa ifudumele phakathi kwe-425-815 ℃ okanye ipholile kancinci kolu luhlu lwamaqondo, i-chromium carbides icocmate kwimida yengqolowa. Lo mgangatho we-chromium kwimimandla yemida yokudla okuziinkozo yenza ukuba intsimbi inesitya esichaphazeleka kukungabinambonakalo. Phantsi koxinzelelo, intsimbi inokuqhekeza kule mida yengqolowa, ekhokelela kwilahleko enkulu yamandla kunye nokunganyangeki.

Izinto ezinokuba negalelo kwi-insosion ye-intergrather:

• Umxholo wekhabhoni ephezulu: Inqanaba lekhabhoni eliphakanyisiweyo kwintsimbi ikhuthaza ukumiswa kwe-chromium carbides.

• Ukuvezwa kweqondo lobushushu: Ukuvezwa kwexesha elide kuluhlu lobushushu bemvakalelo (425-815 ℃) ngexesha lokuphathwa kwe-welding okanye ubushushu.

• Iindawo zemithombo yoqoqosho: Ukuvezwa kwemithombo yeendaba ngoburharha, njengeasids okanye i-chlolor, ukukhawulezisa inkqubo yokulungela.

Iindlela zokuthintela:

1. Ulawulo lweekhemikhali

• Ukongeza izinto zokuzinzisa njenge-titanium okanye i-niobium ukuya kwikhabhoni, ukuthintela ukwenziwa kwe-chromium ye-chromium.

• Sebenzisa intsimbi engenasitali ephantsi (umzekelo, nge-304l, 316l) ngomxholo wekhabhoni ngaphantsi kwe-0.03%.

• Ukulungelelanisa ukwakhiwa kweekhemikhali kwe-weld ukuya kunyusa iqhezu le-chrome.

2. Inkqubo ye-Welding yeWelding:

• Ukunciphisa igalelo lobushushu kunye nokulawula indawo echaphazelekayo yobushushu (i-HAZ).

• Ukusebenzisa ubuchwephesha obukhawulezileyo kunye nobuchule bokupholisa ukunciphisa ixesha elichithwe kuluhlu lobushushu bemvakalelo.

3. Unyango oluqaqambileyo:

• Inkqubo yonyango lobushushu ibandakanya ukufudumeza ngokukhawuleza intsimbi kwiqondo lokushisa eliphezulu kwaye emva koko ikhala ngokukhawuleza ukunyibilikisa i-carbides ye-chromium kwaye ibuyise ukumelana nokubuyisa i-crosion.

• Umzekelo, izixhobo zeTekhnoloji ye-Intanethi ye-intanethi ye-intanethi i-heats kwaye ipholile imibhobho yentsimbi engenasitayile phantsi kokhuseleko lwegesi, ukusebenzisa ubushushu bokufudumeza kunye ne-Hydrogen-Coutite ye-Hydrogen.

Ukubaluleka konyango oluqaqambileyo lwesisombululo:

Unyango oluqaqambileyo lubalulekile ekuveliseni imibhobho ephakathi ye-Welfmed. Isusa ingozi yengozi yokukhutshelwa i-intergranium ngokuqinisekisa ukuhanjiswa kwe-chromium kwindawo yentsimbi. Le nkqubo ibaluleke kakhulu kwizicelo apho intsimbi engenazibala ivezwe kwiindawo ezinobuchule okanye ziphantsi koxinzelelo oluphezulu.

ISIQINISEKISO:

Ukuqonda kunye nokuthintela ukuvela okuxhamla kubalulekile ukuze kuqinisekiswe ububele kunye nokuthembeka kwezinto ezingenasiseko. Ngokulawula ukwakhiwa kweekhemikhali, ukuxhasa iinkqubo ze-welding, kunye nokuphumeza unyango lwesisombululo esiqaqambileyo, abavelisi banokunciphisa kakhulu umngcipheko wendlela eyonakalisayo.
