Indlela yokukhetha ucingo lokushisa olumelana nokumelana

• (1) Ezinkampanini ezithengayo njengalezo ezithengisa imishini yemishini, imishini yokuvala, imishini yokupakisha, njll., singaphakamisa ukuthi kusetshenziswe ucingo lwe-NiCr lochungechunge lwe-cr20Ni80 njengoba izidingo zalo zokushisa ziphansi. Kunezinzuzo ezithile ngokusebenzisa ucingo lwe-NiCr. Alugcini nje ngokuba nokushibilika okuhle kakhulu, kodwa futhi luthambile futhi aluqhekeki. Kungaba ngcono ukusebenzisa i-strip form factor njengoba umthwalo wobuso ngemitha yesikwele ye-strip mkhulu kunentambo eyindilinga. Ngaphezu kobubanzi bayo obubanzi, ukuguguleka kwayo kuncane kunentambo eyindilinga.
• (2) Ezinkampanini ezithengayo njengalezo ezithengisa izitofu zikagesi, izitofu zokubhaka, njll., singancoma i-0cr25al5 FeCrAl evame kakhulu njengoba izidingo zazo zokushisa zingasukela ku-100 kuya ku-900°C. Naphezu kokuthi kufanele kucatshangelwe izinkinga zokushisa kanye nokwenyuka kwezinga lokushisa, akudingi ukusebenzisa ucingo lokushisa lokumelana olunekhwalithi ephezulu kanye nokusebenza kahle. Akukhona nje kuphela ukuthi lushibhile, kodwa futhi lunezinga lokushisa lokusebenza eliphakeme elingu-900°C. Uma ubuso bentambo yokushisa yokumelana buthole ukwelashwa kokushisa, ukwelashwa nge-asidi noma ukuncibilikiswa, izakhiwo zayo ze-oxidation zizothuthukiswa kancane, okuholela esilinganisweni sentengo nokusebenza okuphezulu.
  • Uma isithando somlilo sisebenza ku-900 kuya ku-1000°C, singakweluleka ukuthi usebenzise i-0cr21al6nb njengoba lolu chungechunge lwentambo yokushisa ekwazi ukumelana nokumelana lunamandla okushisa aphezulu futhi ikhwalithi yalo nayo ivelele kakhulu ngenxa yokwengezwa kwezinto ze-Nb.
  • Uma isithando somlilo sisebenza ku-1100 kuya ku-1200°C, singaphakamisa ukuthi kusetshenziswe ucingo oluyindilinga lwe-Ocr27al7mo2 njengoba luqukethe i-MO okuholela ekukhuthazeleni okuphezulu uma kuqhathaniswa nokushisa. Uma ubumsulwa be-Ocr27al7mo2 buphakeme, kulapho amandla ayo okuthamba aphezulu futhi izici zayo zokubola ziba ngcono. Noma kunjalo, luzophuka kakhulu. Ngakho-ke, kumele luphathwe ngokucophelela okukhulu ngesikhathi sezinqubo zokuphakamisa nokubeka. Kungaba ngcono ukuvumela ifektri ukuthi iyisonge ibe nobukhulu obufanele ukuze inkampani ethengayo ikwazi ukuyisebenzisa ekusetshenzisweni kwayo emuva efektri yayo.
  • Uma isithando somlilo sisebenza ekushiseni okuphezulu okungu-1400°C, singancoma kakhulu i-TK1 evela ku-TANKII noma i-US sedesMBO noma i-Kanthal APM yaseSweden. Akungabazeki ukuthi intengo nayo ingaba phezulu.
• (3) Ezinkampanini zokuthenga ezifana nalezo ezithengisa izinto zobumba nezingilazi, singakweluleka ukuthi kusetshenziswe ngqo i-HRE evela ku-TOPE INT'L noma ucingo lokushisa olumelana nokumelana olungenisiwe. Kungenxa yokuthi ucingo lokushisa olumelana nokumelana luzodlidliza kakhulu ngaphansi kwamazinga okushisa aphezulu. Uma ludlidliza isikhathi eside, ucingo lokushisa olumelana nokumelana olunekhwalithi embi ekugcineni luzowohloka futhi luthelele imikhiqizo yokugcina. Kuphela ngokukhethwa kocingo lokushisa olumelana nokumelana olusezingeni eliphezulu, isilinganiso sentengo nokusebenza okungcono sizobe sesifinyelelwa.
