Indima ye-graphite mold ekutshiseni

Ii-graphite molds zidlala indima ebalulekileyo ekufakeni i-brazing, ikakhulu kuquka ezi zinto zilandelayo:

• Ilungisiwe kwaye ibekwe kwindawo ethile ukuqinisekisa ukuba i-weldment igcina indawo ezinzileyo ngexesha lenkqubo yokuqhobosha, ithintela ukuba ingashukumi okanye iguquguquke, ngaloo ndlela iqinisekisa ukuchaneka kunye nomgangatho we-welding.
  Ulawulo lokudlulisa ubushushu kunye nobushushu Ngenxa yokuba i-graphite inomoya ofanelekileyo wokushisa, inokudlulisa ubushushu ngokukhawuleza nangokulinganayo, nto leyo enceda ukulawula ukusasazwa kobushushu ngexesha lenkqubo yokufakela i-brazing, ukuze izinto zokufakela i-brazing zinyibilike ngokupheleleyo kwaye zizalise i-weld ukuze kufezekiswe uqhagamshelo oluhle.
  Ukwenza imo ethile kunye nolwakhiwo Ingakhiwa ibe yimo ethile kunye nolwakhiwo njengoko kufuneka ukunceda ekwenzeni ijoyinti yokudibanisa kunye nohlobo lwe-weldment oluhlangabezana neemfuno.
  Isiphumo sokukhusela Inika ukhuseleko oluthile kwi-weldment kwaye inciphisa ukuphazamiseka kunye nempembelelo yendalo yangaphandle kwinkqubo yokuqhoboshela, njengokuthintela i-oxidation.

Ii-graphite molds zinezibonelelo ezininzi ezibalulekileyo zokugquma:

• Ukuqhuba kakuhle kobushushu Ingadlulisela ubushushu ngokukhawuleza, yenze ukuba izinto zokugquma zinyibilike ngokulinganayo, iphucule ukusebenza kakuhle kunye nomgangatho woqhagamshelo Ingamelana kakuhle nobushushu obuphezulu Ingahlala izinzile kwindawo yokugquma yobushushu obuphezulu, akukho lula ukuyiguqula okanye ukuyonakalisa.
  Uzinzo oluphezulu lweekhemikhali Akulula ukusabela ngokweekhemikhali ngezinto zokugquma kunye nokugquma, ukuqinisekisa ubunyulu kunye nozinzo lwenkqubo yokugquma.
  Ixabiso eliphantsi kakhulu Xa kuthelekiswa nezinye izinto ezimelana nobushushu obuphezulu, ixabiso lezinto ezibumba amatye liphantsi kakhulu, nto leyo enceda ekunciphiseni iindleko zemveliso.

Iinkuni zegrafiti zinempembelelo ebalulekileyo kumgangatho webrazing:

• Ichaphazela isiphumo sokuzaliswa kwe-weld
  I-graphite mold efanelekileyo inokuqinisekisa ukuba izinto zokugquma ziyayizalisa ngokupheleleyo i-weld, zenze i-joint edibeneyo efanayo nexineneyo, kwaye iphucula amandla kunye nokutywinwa kwe-joint.
  Misela isakhiwo se-microstructure yelungu
  Ukusebenza kokudlulisa ubushushu kunye nokuma kwesikhunta kuya kuchaphazela ukusasazwa kobushushu kunye nesantya sokupholisa ngexesha lenkqubo yokugquma, ngaloo ndlela kuchaphazela ulwakhiwo lwe-microstructure kunye nokusebenza kwejoyinti.
  Ichaphazela ukuchaneka kobukhulu be-weldment
  Ukuchaneka kwesikhunta kunxulumene ngokuthe ngqo nokuchaneka kwemilinganiselo yesikhunta. Ukuba ukuchaneka kwesikhunta akuphezulu, kunokubangela ukuphambuka kwemilinganiselo yesikhunta kwaye kuchaphazele ukusebenza kwaso.
