Intambo ye-nichrome ye-Nicr7030iyinto esezingeni eliphezulu ye-austenitic nickel-chromium alloy eyakhiwe yi-nickel engu-70% kanye ne-chromium engu-30%. Ivelele emakethe ngenxa yezakhiwo zayo eziphelele ezivelele: izinga lokushisa eliphezulu lokusebenza eliqhubekayo elifika ku-1250°C (izinga lokushisa eliphakeme lesikhathi esifushane lingaba ngu-1400°C), ukumelana kukagesi okuzinzile (1.18 Ω・mm²/m ku-20°C), ukumelana okuvelele kwe-oxidation (okwakha ifilimu evikelayo ye-Cr₂O₃ emazingeni okushisa aphezulu), kanye nokushibilika okuhle kakhulu kanye nokuguquguquka. Lezi zici eziphakeme ziyenza ibe yinto eyinhloko engenakuphikwa emikhiqizweni eminingi yezimboni, kuma-electronics abathengi, kanye nasezindaweni zocwaningo ezisezingeni eliphezulu. Ngezansi ukuhlukaniswa okuningiliziwe kwezimo zayo eziyinhloko zokusetshenziswa:
| Insimu Yesicelo | Izinzuzo Eziyinhloko Ezisetshenzisiwe | Ukusetshenziswa Okuvamile |
| Ukushisa Kwezimboni | Ukumelana nokushisa okuphezulu (ukusetshenziswa okuqhubekayo okungu-1250°C), ukulwa nokubola, ukulwa "nokubola okuluhlaza" (ukubola okuphakathi kwe-granular), ukumelana okuzinzile | Izinto zokushisa zesithando sezimboni (izithando zokufaka amazinyo, izithando zokushisa), izifudumezi zokukhiqiza ingilazi (izithando zokushisa, imishini yokudweba ifayibha), imishini yokushisa yokucubungula insimbi (izikhunta zokushisa), izintambo zokushisa ezishisa kakhulu, izifudumezi zomshini wokwelula ifilimu yepulasitiki |

Isingeniso Sesicelo Esiningiliziwe
Ku-umkhakha wokushisa wezimboni, Intambo ye-Nicr7030 yaziwa kabanzi njengezinto ezikhethwayo zezinto zokushisa ezinobungozi endaweni. Ngokungafani nezinto zokushisa ezivamile, isici sayo esiyingqayizivele sokulwa "nokubola okuluhlaza" (ukumelana ne-oxidation ye-intergranular) siqinisekisa ukusebenza okuthembekile ekunciphiseni imimoya kanye nezindawo zokushisa okuphezulu, okubalulekile ezitsheni zezimboni ezisetshenziswa ekufakweni nasekuthungeni insimbi. Ekukhiqizeni ingilazi, ukumelana okuzinzile kwentambo kuqinisekisa ukushisa okufanayo kwezitofu zokushisa kanye nemishini yokudweba ifayibha, okuvimbela ukukhubazeka komkhiqizo okubangelwa ukushintshashintsha kwezinga lokushisa. Ngaphezu kwalokho, ukupakishwa kwayo okuhlanganisiwe (okutholakala kuma-roll angu-100m-1000m) kusekela ukondla okuqhubekayo okuzenzakalelayo, okuthuthukisa kakhulu ukusebenza kahle kokukhiqiza ekukhiqizweni kwe-heater coil. Uma kuqhathaniswa nentambo ye-alloy ye-Nicr8020, i-Nicr7030 inikeza ukuguquguquka okungcono kanye nokusebenza kahle kwezindleko, okwenza ifaneleke kakhulu ezisetshenzisweni ezinkulu zezimboni ezidinga ukugoba nokwakheka okuyinkimbinkimbi.
Ngobaizinto zasekhaya, Ukusebenza kokushisa okusheshayo kwentambo ye-Nicr7030 (ukufinyelela izinga lokushisa elibekiwe ngaphakathi kwemizuzwana emi-3-5) kanye nokusatshalaliswa kokushisa okufanayo kuthuthukisa ulwazi lomsebenzisi emikhiqizweni eyahlukahlukene. Ezintweni zasekhishini ezifana nama-oven nama-microwave, ukumelana nokushisa okuphezulu kwentambo kuqinisekisa ukusebenza okuzinzile kwesikhathi eside ngaphandle kokwehla kokusebenza. Emikhiqizweni yokunakekelwa komuntu siqu njengezingubo zikagesi nama-heating pad, ihlangabezana nezindinganiso zokuphepha zomhlaba wonke (isb., i-IEC 60335) enobuthi obuphansi kanye nokuhambisana okuhle kakhulu kokushisa. Ukuphila kwayo isikhathi eside kwenkonzo (kufika emahoreni angu-8000 okusetshenziswa okuqhubekayo) kunciphisa izindleko zokulungisa nokufaka esikhundleni sabakhiqizi bemishini, kuyilapho izici zayo ezisebenzisa amandla kahle zihambisana nemikhuba yokuvikela imvelo yomhlaba wonke.
Iimboni yezimotoIzuza kakhulu ekhonweni lentambo ye-Nicr7030 lokugcina ukuzinza kwemishini ngaphansi kokushintshashintsha okukhulu kwezinga lokushisa. Ezimotweni zikagesi nasezimotweni zendabuko, isetshenziswa ezinhlelweni zokushisa izihlalo neziteringi, ihlinzeka ngokufudumala okuqhubekayo ngisho nasezindaweni ezishisa kancane -40°C. Ukumelana nokugqwala kwentambo kuqinisekisa ukuthi ingakwazi ukumelana nendawo enomswakama necebile ngamakhemikhali yangaphakathi kwezimoto, igweme ukwehluleka kwangaphambi kwesikhathi okubangelwa umswakama noma ukuvuza kwe-coolant. Ngaphezu kwalokho, ububanzi bayo obuncane (kufika ku-0.1mm) buvumela ukwakheka okufushane, okungena kalula ngaphakathi kwezimoto zesimanje ngaphandle kokuthatha isikhala esengeziwe.
In izinhlelo zokusebenza zikagesi neze-elekthronikhi, Ukumelana okuzinzile kakhulu kwentambo ye-Nicr7030 (ene-coefficient yokushisa yokumelana ephansi njengo-0.0004/°C) kubalulekile ezingxenyeni ze-elekthronikhi ezinembile. Isetshenziswa kabanzi kuma-resistor amanje kanye nama-circuits ephaneli yezinsimbi, okuqinisekisa ukudluliselwa kwesignali okunembile kanye nokulinganisa. Ukuguquguquka kwayo okuhle kakhulu kwenza ukuthi idonswe ezintanjeni ezincane kakhulu (0.01mm) zezinzwa ze-elekthronikhi ezincane kanye nama-solenoid valve coil emigqeni yokukhiqiza ezenzakalelayo. Uma kuqhathaniswa nentambo yethusi, i-Nicr7030 inikeza ukumelana okuphezulu, okuvumela osayizi bezingxenye ezincane ngenkathi igcina inani elifanayo lokumelana, okubalulekile ekuthambekeleni kokunciphisa kwamadivayisi kagesi.
In ucwaningo lwesayensi kanye nokukhiqiza okuthuthukisiwe, Ucingo lwe-Nicr7030Ukuqina kokujikeleza kokushisa kanye nokucutshungulwa okwenziwe ngokwezifiso kwenza kube ithuluzi elibalulekile. Isekela ukuhlolwa kwezinto ezishisa kakhulu (isb., ukuhlolwa kokumelana nokushiswa kwensimbi) ngokubekezelela imijikelezo yokushisa engaphezu kwe-1000 ngaphandle kokuguqulwa noma ukulahlekelwa ukusebenza. Ocwaningweni lwezindiza, isetshenziswa emishinini yokulingisa ukushisa ukuphinda izindawo zokushisa ezishisayo ezibhekene nezingxenye zezindiza. Ekukhiqizweni kokuphrinta kwe-3D kanye ne-semiconductor, ukuhambisana kwentambo nezindawo ze-vacuum kanye negesi engasebenzi kuqinisekisa ukusebenza okuthembekile ezinqubweni zokukhiqiza ezikhethekile. Siphinde sinikeze imininingwane eyenziwe ngokwezifiso (isb., ama-alloys akhethekile, ububanzi obungejwayelekile) ukuze kuhlangatshezwane nezidingo ezihlukile zamaphrojekthi ocwaningo lwesayensi.
Sekukonke, ukuguquguquka kwe-Nicr7030 nichrome wire, ukuthembeka kwayo, kanye nokusebenza kwayo okuphezulu kwenza kube ukukhetha okuthembekile kuzo zonke izimboni. Kungakhathaliseki ukuthi kusezindaweni zezimboni ezidinga kakhulu, imikhiqizo yabathengi yansuku zonke, noma emikhakheni yocwaningo olusezingeni eliphezulu, ihlinzeka ngokusebenza okuzinzile nokuphumelelayo njalo. Inkampani yethu inikeza ukwesekwa kobuchwepheshe okuphelele, okuhlanganisa ukubonisana ngokukhetha izinto, ukuhlolwa kwamasampula, kanye nokucutshungulwa ngokwezifiso, ukusiza amakhasimende ukuthi andise inani le-Nicr7030 wire ezinhlelweni zawo ezithile.
