Indlela yokukhetha intambo yokushisa yokumelana

• (1) Ezinkampanini ezithengayo ezifana nalezo ezisebenza ngemishini, imishini yokuvala, imishini yokupakisha, njll., singaphakamisa ukuthi kusetshenziswe intambo ye-NiCr yochungechunge lwe-cr20Ni80 njengoba izidingo zabo zokushisa zingekho phezulu.Kukhona izinzuzo ezithile ngokusebenzisa intambo ye-NiCr.Ayigcini nje ngokuba nokushisela okuhle kakhulu, futhi ithambile ngokuqhathaniswa futhi ayishwabanisi.Kungaba ngcono ukusebenzisa i-strip form factor njengoba umthwalo ongaphezulu ngemitha-skwele ngayinye yomugqa mkhulu kunocingo oluyindilinga.Phezu kobubanzi bayo obubanzi, ukuguga kwayo kuncane kunocingo oluyindilinga.
• (2) Ezinkampanini ezithengayo ezifana nalezo ezisebenzelana neziko likagesi, iziko lokubhaka, njll., singancoma i-0cr25al5 FeCrAl evame kakhulu njengoba izimfuneko zazo zokushisa zingasukela kokuphakathi kuka-100 kuya ku-900°C.Naphezu kokuthi kufanele kucatshangelwe izinkinga zezinga lokushisa nokukhuphuka kwezinga lokushisa, akudingi ukusebenzisa intambo yokushisisa yokumelana nekhwalithi nokusebenza okungcono kakhulu.Akukhona nje kuphela ukuthi ishibhile, futhi inezinga lokushisa eliphakeme lokusebenza elingu-900°C.Uma ingaphezulu lentambo yokushisisa ekwazi ukumelana nokushisa ithole ukwelashwa okune-asidi noma i-annealing, izici zayo ze-oxidation zingathuthukiswa kancane, okuholela esilinganisweni esiphezulu kakhulu sokusebenza kwentengo.
  • Uma isithando somlilo sisebenza ku-900 kuya ku-1000 ° C, sizokweluleka ukusebenzisa i-0cr21al6nb njengoba lolu chungechunge lwezintambo zokushisa eziphikisanayo lunokubekezela okuphezulu kwezinga lokushisa futhi ikhwalithi yalo ibuye ivelele ngenxa yokwengezwa kwezakhi ze-Nb.
  • Uma isithando somlilo sisebenza ku-1100 kuya ku-1200°C, singaphakamisa ukuthi kusetshenziswe intambo eyindilinga ye-Ocr27al7mo2 njengoba iqukethe i-MO ephumela ekukhuthazeleni okuphezulu ngokumelene nezinga lokushisa.Uma buphezulu ubumsulwa be-Ocr27al7mo2, buyanda amandla ayo aqinile futhi kuba ngcono izindawo zayo ze-oxidation.Noma kunjalo, bekuzoba brittle ngokwandayo.Ngakho-ke, kufanele isingathwe ngokunakekela okwengeziwe ngesikhathi sokuphakamisa nokubeka.Kungaba kuhle kakhulu ukuvumela ifekthri ukuthi iyibophe ngezilinganiso ezifanele ukuze inkampani ethengayo ivele iyisebenzisele ukusetshenziswa kwayo emuva efekthri yayo.
  • Ngeziko elisebenza ezingeni lokushisa eliphakeme elingu-1400°C, singancoma kakhulu i-TK1 evela ku-TANKII noma i-US sedesMBO noma i-Kanthal APM yase-Sweden.Ngokungangabazeki, intengo nayo izoba phezulu.
• (3) Ezinkampanini ezithengisa izinto ezifana nalezo ezisebenza ngezinto zobumba nezingilazi, singaluleka ukuthi sisebenzise ngokuqondile i-HRE evela ku-TOPE INT'L noma izintambo zokushisisa ezingenisiwe.Kungenxa yokuthi intambo yokushisisa yokumelana izodlidliza kakhulu ngaphansi kwamazinga okushisa aphezulu.Ngokungaphansi kokudlidliza kwesikhathi eside, intambo yokushisisa yokumelana enekhwalithi ephansi izogcina yonakala futhi itheleleke emikhiqizweni yokugcina.Kuphela ngokukhethwa kwentambo yokushisisa yokumelana nekhwalithi ephezulu, isilinganiso esingcono sokusebenza kwentengo singabe sesifinyelelwa.
