Izinzuzo Zokusebenza kanye Nomhlahlandlela Wesimo Sokusebenza We-High-Chromium Nickel-Chromium Heating Alloys

1. Isingeniso ku-I-Nichrome 70/30 : I-Alloy Yokushisa Esebenza Kakhulu Enokuqukethwe Okuphezulu kwe-Chromium

1.1 Ukwakheka Okuyisisekelo Nokubekwa Komkhiqizo

I-Nichrome 70/30 (ibanga le-Cr30Ni70, eyaziwa nangokuthi i-Ni70Cr30) iyinhlobonhlobo ye-chromium ephezulu emndenini we-nichrome heating alloy, enokwakheka okulinganiselwe okungu-70% nickel kanye no-30% chromium kanye nokungcola okulawulwa ngokuqinile njengensimbi nekhabhoni. Ihlukaniswa njenge-alloy heating resistance ephezulu yezimboni.

Le alloy ihambisana nezindinganiso eziningi zikazwelonke nezamazwe ngamazwe okuhlanganisa i-GB/T 1234, i-ASTM B344 kanye ne-DIN 17470. Iyinto ethuthukisiwe elinganisela ukuqina kokushisa okuphezulu, ukumelana nokushiswa kwe-oxidation kanye nokunemba kokumelana, okwenza ifanelekele izimo zokushisa eziphezulu ezinezimo zokusebenza eziyinkimbinkimbi.

1.2 Izici Ezine Zokusebenza Eziyinhloko

Izinga lokushisa eliphakeme lesevisi: Isekela izinga lokushisa lokusebenza eliqhubekayo isikhathi eside elifinyelela ku-1250°C kanye nezinga lokushisa eliphakeme lesikhathi esifushane eliyi-1300°C, eliphakeme kunezinga elivamile le-Nichrome 80/20.

Ukumelana okuphezulu kukagesi: Ukumelana nokushisa kwegumbi layo cishe kungama-1.18 μΩ·m, kanye ne-coefficient yokumelana nokushisa okuphansi. Ukuguquguquka kwamandla kuthambile ngesikhathi sokushisa, okuvumela ukunemba okuphezulu kokulawula izinga lokushisa.

Ukushiswa kwe-oxidation okunamandla kanye nokumelana nokugqwala okuluhlaza: Okuqukethwe okuphezulu kwe-chromium kwakha ifilimu yokuvikela i-oxide eningi kakhulu emazingeni okushisa aphezulu, okunikeza ukusebenza okuhle kakhulu ekushintsheni i-oxidizing/reduction atmospheres kanye nokwandisa ngempumelelo impilo yesevisi yezakhi.

Izakhiwo zemishini ezizinzile ezinokushisa okuphezulu: Inokumelana okuhle kakhulu kokuqhekeka kanye nokumelana nokuguquguquka emazingeni okushisa aphezulu. Ayiguquki kalula noma ibole ngemva kokusetshenziswa isikhathi eside, okuqinisekisa ukuzinza okuhle kwesakhiwo sezinto zokushisa.

2. Izimo Eziyisithupha Zokusetshenziswa Kwezimboni Eziyinhloko ze-Nichrome 70/30

2.1 Izinto Zokushisa Zezithando Zokushisa Zezimboni Ezisezingeni Eliphezulu

Lolu uhlelo lokusebenza oluvame kakhulu lwe-Nichrome 70/30, ikakhulukazi kuma-furnace amelana nokushisa okuphezulu asezingeni lika-1200°C, ama-furnace e-carburizing, ama-furnace e-bell kanye nama-furnace e-tempering.

Njengoba ibhekene nezimo ze-furnace eziyinkimbinkimbi kanye nokushintshashintsha okukhulu kwezinga lokushisa, ukumelana kwayo nokugqwala okuphezulu komkhathi kungandisa kakhulu impilo yensiza yokushisa, ende cishe ngo-40% kune-alloys evamile.

2.2 Ukushisa Kwesitofu Ezimbonini Zengilazi Neze-Ceramic

Izindawo zokushisa zezithando zokuncibilikisa ingilazi kanye nezithando zokushisisa ze-ceramic zinezinga lokushisa eliphezulu kanye nomoya onzima womusi we-alkaline, ongcolisa kakhulu izinto zokushisa.

Ifomula ye-Nichrome 70/30 ene-chromium ephezulu imelana kangcono nokuguguleka komkhathi we-alkaline, igcina amandla okushisa azinzile, iqinisekisa ukufana kwezinga lokushisa kuzo zonke izindawo zesitofu, futhi inciphisa isikhathi sokungasebenzi sokufakwa kwezakhi.

2.3 Amayunithi Okushisa Okukhiqiza Ama-Semiconductor kanye Nama-Electronics

Izinqubo ezifana nokunamathisela i-semiconductor wafer, ukubopha kwe-thermocompression yephakheji kanye nokusinta izingxenye ze-elekthronikhi kubeka izidingo eziphezulu kakhulu ekufaneni nasekuhlanzekeni kwezinga lokushisa.

Le alloy inokumelana okuzinzile kanye nokukhiqizwa kokushisa okufanayo, kanye ne-volatile matter ephansi emazingeni okushisa aphezulu angeke angcolise indawo yenqubo. Ivame ukwenziwa ibe yizinduku zokushisa ezinembile kanye namapuleti okushisa emishini yokukhiqiza kagesi ephezulu.

2.4 Ama-Resistors Aqondile kanye Nezinto Zenzwa

Njengoba ine-coefficient yokumelana nokushisa okuphansi kanye nokungaguquguquki okuhle kakhulu kokumelana kwesikhathi eside, i-Nichrome 70/30 isetshenziselwa ukukhiqiza ama-resistor anembe kakhulu nama-resistor cores ezinzwa ze-oxygen zezimoto.

Ukusebenza kwayo kuhlangabezana nesidingo esiqinile sokumelana kwe-TCR yezinga lezempi ≤ 50 ppm/°C, okugcina ukumelana okuzinzile kulo lonke izinga lokushisa elibanzi.

2.5 Imishini Yokushisa Yasekhaya Neyezentengiselwano Esezingeni Eliphezulu

I-Nichrome 70/30 nayo iyinto ekhethwayo kuma-oven asezingeni eliphezulu, izibhamu zokushisa zezimboni, isikhunta sepulasitiki esishintshashintshayo kanye neminye imikhiqizo yezentengiselwano/yasekhaya edinga isikhathi eside sokushisa kanye nokuqina okuphezulu.

Uma kuqhathaniswa nentambo evamile ye-nichrome, ibekezelela imijikelezo evame kakhulu yokushisa okubandayo futhi inokunciphisa amandla okuncane ngemva kokusetshenziswa isikhathi eside, okuthuthukisa ukuthembeka komkhiqizo jikelele.

2.6 Ukushisa Okukhethekile Ezimbonini Zamakhemikhali Nezensimbi

Ezimweni ezifana nokushisa komkhathi okugqwalisayo embonini yamakhemikhali kanye nezitofu zokuncibilikisa amasampula embonini yensimbi, izinto ezivamile zivame ukwehluleka ukugqwala.

I-Nichrome 70/30 ibekezelela kahle izimo ezahlukahlukene ze-asidi ne-alkali, futhi ingasebenza ngokuqina ezindaweni ezishisa kakhulu ezinokugqwala okuncane, yandisa umngcele wokusetshenziswa kwezinsimbi zokushisa zikagesi.
