Indlela yokukhetha ukuxhathisa ukufudumeza ucingo

• (1) Kwiinkampani ezithengayo ezifana nezo zisebenza ngoomatshini, oomatshini bokutywina, oomatshini bokupakisha, njl.njl., singacebisa ukuba kusetyenziswe ucingo lwe-NiCr loluhlu lwe-cr20Ni80 njengoko iimfuno zabo zobushushu zingekho phezulu. Kukho iingenelo ezithile usebenzisa ucingo lwe-NiCr. Ayinabunewunewu obugqwesileyo kuphela, ikwathambile ngokuthelekisayo kwaye ayibi brittle. Kungangcono ukusebenzisa i-strip form factor njengoko umthwalo womphezulu we-square meter nganye yomtya mkhulu kunocingo olungqukuva. Ngaphezulu kobubanzi bayo obubanzi, ukuguga kwayo kunye nokukrazula kuncinci kunocingo olujikelezayo.
• (2) Kwiinkampani ezithengayo ezifana nezo zisebenza kwiziko lombane, iziko lokubhaka, njl.njl., singacebisa eyona ixhaphake kakhulu i-0cr25al5 FeCrAl njengoko iimfuno zabo zobushushu zinokususela kwi-100 ukuya kuma-900°C. Nangona kufuneka kuqwalaselwe imiba yobushushu kunye nokunyuka kwamaqondo obushushu, ayifuni ukusebenzisa ucingo lokufudumeza olunomgangatho ophezulu kunye nokusebenza. Ayinexabiso eliphantsi kuphela, ikwanobushushu bokusebenza obuphezulu obungama-900°C. Ukuba umphezulu wocingo lokufudumeza oluxhathisayo lufumene unyango lobushushu, unyango lwe-asidi okanye i-annealing, iipropati zayo ze-oxidation zingaphuculwa kancinane, okukhokelela kumlinganiselo ophezulu wexabiso-ukusebenza.
  • Ukuba isithando somlilo sisebenza kwi-900 ukuya kwi-1000 ° C, siyakucebisa ukuba sisebenzise i-0cr21al6nb njengoko olu chungechunge lwecingo lokufudumeza oluxhathisayo lunokunyamezela kokushisa okuphezulu kunye nomgangatho walo nawo ubalaseleyo ngenxa yokongezwa kwezinto ze-Nb.
  • Ukuba isithando somlilo sisebenza kwi-1100 ukuya kwi-1200 ° C, sinokucebisa ukusebenzisa ucingo olujikelezileyo lwe-Ocr27al7mo2 njengoko luqulethe i-MO ebangela ukunyamezela okuphezulu kwiqondo lokushisa. Okona kuphezulu ubunyulu be-Ocr27al7mo2, kokukhona kuphezulu amandla ayo okuxinana kwaye ngcono iimpawu zayo ze-oxidation. Nangona kunjalo, iya kuba brittle ngakumbi. Ngaloo ndlela, kufuneka iphathwe ngononophelo olongezelelweyo ngexesha lokunyusa kunye nokubeka iinkqubo. Kuya kuba kuhle ukuvumela umzi-mveliso ukuba uwudibanise kwimilinganiselo efanelekileyo ukuze inkampani ethengayo ikwazi ukuyisebenzisela ukusetyenziswa kwayo emva kumzi-mveliso wayo.
  • Kwiziko elisebenza kubushushu obuphezulu be-1400 ° C, singacebisa kakhulu i-TK1 esuka kwi-TANKII okanye i-US sedesMBO okanye i-Sweden Kanthal APM. Ngaphandle kwamathandabuzo, ixabiso liya kuba phezulu.
• (3) Kwiinkampani ezithengisayo ezifana nezo zisebenza kwiiseramics kunye neeglasi, siyakucebisa ukuba sisebenzise ngokuthe ngqo i-HRE ukusuka kwi-TOPE INT'L okanye ucingo olushushu olwenziwa ngaphandle. Kungenxa yokuba ucingo lokufudumeza oluxhathisayo luya kungcangcazela kakhulu phantsi kobushushu obuphezulu. Ngokuxhomekeke kungcangcazelo lwexesha elide, ucingo lokufudumeza olunomgangatho ophantsi luya kuthi ekugqibeleni luwohloke kwaye losulele iimveliso zokugqibela. Kuphela ngokukhethwa komgangatho ophezulu wokumelana nocingo lokufudumeza, umlinganiselo ongcono wexabiso lokusebenza uya kufumaneka.
