Indima ye-graphite mold kwibrazing

Imibumbo yegraphite idlala indima ebalulekileyo ekubhubhiseni, ngakumbi kubandakanya le miba ilandelayo:

• I-Fixed kwaye ibekwe ukuze kuqinisekiswe ukuba i-weldment igcina isikhundla esizinzile ngexesha le-brazing process, ukukhusela ukuba ihambe okanye iphazamise, ngaloo ndlela iqinisekisa ukuchaneka kunye nomgangatho we-welding.
  Ukutshintshwa kobushushu kunye nokulawulwa kweqondo lokushisa Ngenxa yokuba i-graphite ine-conductivity efanelekileyo ye-thermal, inokukhawuleza kwaye idlulise ukushisa ngokulinganayo, okunceda ukulawula ukuhanjiswa kweqondo lokushisa ngexesha lenkqubo yokubhobhoza, ukwenzela ukuba izinto zokuqhafaza zikwazi ukunyibilika ngokupheleleyo kwaye zizalise i-weld ukufezekisa uxhulumaniso oluhle.
  Ukwenza imilo ethile kunye nesakhiwo Inokuthi iyilwe ibe yimeko ethile kunye nesakhiwo njengoko kuyimfuneko ukunceda ukwenza i-welding joint kunye ne-weldment shape ehlangabezana neemfuno.
  Impembelelo ekhuselayo Inika ukhuseleko oluthile lwe-weldment kunye nokunciphisa ukuphazamiseka kunye nefuthe lendawo yangaphandle kwinkqubo yokuqhaqha, njengokuthintela i-oxidation.

Imibumbo yegraphite ineengenelo ezininzi ezibalulekileyo zokujongisa:

• I-conductivity egqwesileyo ye-thermal Inokudlulisa ngokukhawuleza ubushushu, yenza ukuba izinto zokuqhafaza zinyibilike ngokulinganayo, ziphucule ukusebenza kakuhle kunye nomgangatho woxhulumaniso Ukumelana nokushisa okuphezulu kweqondo lokushisa Kunokuhlala kuzinzile kwindawo yokushisa ephezulu yokushisa, akukho lula ukuphazamisa okanye ukonakala.
  Ukuzinza kweekhemikhali eziphakamileyo Akulula ukusabela ngamachiza kunye nezinto zokuqhafaza kunye ne-weldment, ukuqinisekisa ukucoceka kunye nokuzinza kwenkqubo ye-welding.
  Ixabiso eliphantsi xa kuthelekiswa nezinye izinto ezixhathisa ubushushu obuphezulu, iindleko zokubumba amatye zinoqoqosho ngokwentelekiso, nto leyo enceda ekunciphiseni iindleko zemveliso.

Ukubumba kwegraphite kunempembelelo ebalulekileyo kumgangatho wokubrawuza:

• Ukuchaphazela umphumo wokuzaliswa kwe-weld
  Isikhunta esifanelekileyo se-graphite sinokuqinisekisa ukuba izinto zokubhobhoza zizalisa ngokupheleleyo i-weld, zenze i-uniform kunye ne-dense welded joint, kunye nokuphucula amandla kunye nokutywinwa kokudibanisa.
  Ukumisela i-microstructure ye-joint
  Ukusebenza kokutshintshwa kobushushu kunye nokuma kwesikhunta kuya kuchaphazela ukuhanjiswa kweqondo lokushisa kunye nesantya sokupholisa ngexesha lenkqubo yokutshisa, ngaloo ndlela kuchaphazela i-microstructure kunye nokusebenza kokubambisana.
  Ukuchaphazela ukuchaneka komda we-weldment
  Ukuchaneka kwe-mold kuhambelana ngokuthe ngqo nokuchaneka kwe-dimensional ye-weldment. Ukuba ukuchaneka kokungunda akukho phezulu, kunokubangela ukuphambuka kwe-dimensional ye-weldment kwaye kuchaphazele ukusebenza kwayo.
