Indlela yokukhetha ucingo lokufudumeza olumelana nokumelana

• (1) Kwiinkampani ezithengayo ezifana nezo zithengisa izixhobo zoomatshini, oomatshini bokuvala, oomatshini bokupakisha, njl.njl., singacebisa ukuba kusetyenziswe ucingo lweNiCr lothotho lwe-cr20Ni80 kuba iimfuno zabo zobushushu aziphezulu. Kukho iingenelo ezithile zokusebenzisa ucingo lweNiCr. Alupheleli nje ekubeni lunokudityaniswa kakuhle, kodwa luthambile kwaye aluqhekeki. Kungangcono ukusebenzisa i-strip form factor kuba umthwalo womphezulu ngemitha yesikwere se-strip mkhulu kunocingo olujikelezayo. Ngaphezulu kobubanzi bayo obubanzi, ukuguguleka kwayo kuncinci kunocingo olujikelezayo.
• (2) Kwiinkampani ezithengayo ezifana nezo zithengisa izitofu zombane, izitofu zokubhaka, njl.njl., singacebisa eyona 0cr25al5 FeCrAl ixhaphakileyo njengoko iimfuno zazo zobushushu ziya kuba phakathi kwe-100 ukuya kwi-900°C. Nangona kufuneka kuqwalaselwe imiba yobushushu kunye nokunyuka kobushushu, ayifuni ukusebenzisa ucingo lokufudumeza oluchasene nomgangatho kunye nokusebenza kakuhle. Ayibizi nje kuphela, ikwanalo nobushushu obuphezulu bokusebenza be-900°C. Ukuba umphezulu wocingo lokufudumeza oluchasene nokumelana ufumene unyango lobushushu, unyango lwe-asidi okanye i-annealing, iipropati zayo ze-oxidation ziya kwandiswa kancinci, nto leyo ekhokelela kumlinganiselo ophezulu wexabiso nokusebenza.
  • Ukuba isithando somlilo sisebenza kwi-900 ukuya kwi-1000°C, singacebisa ukuba kusetyenziswe i-0cr21al6nb njengoko olu luhlu lweentambo zokufudumeza ezimelana nokumelana nobushushu lunokumelana okuphezulu kwaye umgangatho walo nawo ubalasele kakhulu ngenxa yokongezwa kwezinto ze-Nb.
  • Ukuba isithando somlilo sisebenza kwi-1100 ukuya kwi-1200°C, singacebisa ukuba kusetyenziswe ucingo olujikelezayo lwe-Ocr27al7mo2 njengoko lune-MO ebangela ukuba ikwazi ukumelana nobushushu obuphezulu. Okukhona ubunyulu be-Ocr27al7mo2 buphezulu, kokukhona amandla ayo okutsalwa aphezulu kwaye iimpawu zayo zokunyibilikisa zingcono. Nangona kunjalo, iya kuba buthathaka ngakumbi. Ngenxa yoko, kufuneka iphathwe ngononophelo olukhulu ngexesha leenkqubo zokuphakamisa nokubeka. Kungangcono ukuvumela umzi-mveliso ukuba uyisongele kwimilinganiselo efanelekileyo ukuze inkampani ethengayo ikwazi ukuyisebenzisa kuphela xa isetyenziswa kwakhona kumzi-mveliso wayo.
  • Kwi-furnace esebenza kumaqondo obushushu aphezulu e-1400°C, singacebisa kakhulu i-TK1 evela kwi-TANKII okanye kwi-US sedesMBO okanye kwi-Sweden's Kanthal APM. Ngokungathandabuzekiyo, ixabiso liza kuba phezulu.
• (3) Kwiinkampani ezithenga izinto ezifana nezo zithengisa izinto zodongwe kunye neeglasi, singacebisa ukuba sisebenzise ngqo i-HRE evela kwi-TOPE INT'L okanye ucingo lokufudumeza oluchaseneyo olungeniswe kwamanye amazwe. Kungenxa yokuba ucingo lokufudumeza oluchaseneyo luya kungcangcazela kakhulu phantsi kobushushu obuphezulu. Ukuba luphantsi kokungcangcazela kwexesha elide, ucingo lokufudumeza oluchaseneyo olunomgangatho ophantsi ekugqibeleni luya kubola luze losulele iimveliso zokugqibela. Kuphela ngokukhethwa kocingo lokufudumeza oluchaseneyo olusemgangathweni ophezulu, umlinganiselo ongcono wexabiso uya kufumaneka emva koko.
