Esikhathini lapho ukunemba, ukuqina, nokusebenza kahle kuchaza inqubekelaphambili yezimboni,intambo ye-nichromeiyaqhubeka nokuma njengesisekelo sokuqamba okusha okushisayo. Yakhiwe ngokuyinhloko nge-nickel (55–78%) kanye ne-chromium (15–23%), enamanani ambalwa ensimbi ne-manganese, izici ezihlukile zale alloy ziyenza ibaluleke kakhulu ezimbonini zonkana—kusukela ezintweni zasendlini ukuya kobunjiniyela be-aerospace. Lapha, sihlola ukusetshenziswa okuhlukahlukene kocingo lwe-nichrome kanye nendima yalo ekubumbeni ubuchwepheshe besimanje bokushisa.

 

I-Core Properties Driving Versatility ye-Nichrome

Ivelu ye-Nichrome ilele ekuseleni kwayo okukhethekile kwezici zomzimba nezikagesi. Nge-resistivity engu-1.0–1.1×10⁻⁶ Ω·m kanye nephoyinti lokuncibilika elidlula u-1400°C315, iguqula kahle amandla kagesi abe ukushisa kuyilapho imelana ne-oxidation nokugqwala ngisho nangaphansi kwezimo ezimbi kakhulu. Imvelo yayo engeyona i-magnetic, i-ductility, kanye nokwanda okushisayo okuphansi kuthuthukise ukuguquguquka kwayo315. Lezi zici ziqinisekisa ukusebenza okungaguquguquki ezindaweni ezidinga ukwethembeka, kusukela ezithandweni zezimboni ezinezinga lokushisa eliphezulu ukuya kumadivayisi ezokwelapha anembayo.

 

Izinhlelo zokusebenza ezibalulekile ze-Nichrome Wire

1. Imishini Yasekhaya

I-Nichrome wire iwumgogodla wemishini yokushisisa yansuku zonke. Amathosta, okomisa izinwele, ohhavini, namaketela kagesi kuncike ekhonweni lazo lokukhiqiza ukushisa okusheshayo nokufana okufanayo. Ngokwesibonelo,nichrome 60isetshenziswa kakhulu ezintweni ezishisayo zokushisa okuphakathi njengama-grill nama-heaters okugcina, kuyilapho i-nichrome 80 (Ni80Cr20) ihamba phambili ezinhlelweni ezisebenza ngamandla njengezifudumezi zamanzi nama-ayina okushisa ngenxa yokunamathela kwayo okuphezulu kwe-oxide nokuphila isikhathi eside915.

2. Izinqubo Zezimboni Nezokukhiqiza

Ezilungiselelweni zezimboni, izintambo ze-nichrome zinika amandla izithando zikagesi, ama-kilns, nezinto zokusebenza ezishisayo. Ukumelana kwayo nokukhasa—ukugcina ubuqotho besakhiwo ngaphansi kwengcindezi ehlala isikhathi eside emazingeni okushisa angaphezu kuka-400°C—kuyenza ilungele ukuhushulwa, ukuncibilika, nokwelashwa kokushisa315. Izimboni ezifana ne-metallurgy ne-ceramics zisebenzisa imichilo ye-nichrome namakhoyili ukuze zizinze ekwehliseni umkhathi, zigweme izinkinga ezifana "nokubola okuluhlaza" okubonwa kwamanye ama-alloys9.

 

3. I-Aerospace kanye ne-Automotive Systems

Ukuthembeka kwe-Nichrome kudlulela ezindaweni ezinzima ezifana nezinhlelo zokususa uqweqwe lwe-aerospace, izinzwa zenjini, nezifudumezi zekhabethe. Ikhono layo lokumelana nokuhamba ngebhayisikili okushisayo nezimo ezinzima liqinisekisa ukuphepha nokusebenza kahle ezingxenyeni ezibalulekile15. Izinhlelo zokusebenza zezimoto zifaka izifudumezi zezihlalo namakhebuli anciphisa ukuqina, lapho okuhlukile kwe-nichrome 30 no-40 kunikeza ukufudumeza okuhlala isikhathi eside, ukonga amandla9.

4. Izinsiza Zezokwelapha Nezaselabhorethri

Ekunakekelweni kwezempilo, intambo ye-nichrome inika amandla ukulawula okushisayo kumathuluzi okuhlinzwa, amaphedi okushisisa, namadivayisi wokuvala inzalo. Amalabhorethri asebenzisa ukungabikhona kwawo ekuhlolweni kwelangabi kanye nokuthungela kude kwezinhlanganisela ezisebenzayo, ukunciphisa ubungozi bokungcola715.

5. Izinto Ezintsha Ezisafufusa kanye Nezixazululo Zezifiso

Intuthuko kuma-alloys e-nichrome igxile ekuthuthukiseni ukusebenza kahle ngokuqanjwa okucolisisiwe nezindlela zokukhiqiza. Ukuncibilika kwe-vacuum-induction, isibonelo, kukhiqiza amabanga afana ne-Ni80Cr20-VI, elungiselelwe okokusebenza okunokwethenjelwa okuphezulu kwe-electrothermal3. Ukwengeza, indima ye-nichrome ezintweni zikagesi ezonga amandla kanye nezifutho ezishisayo igqamisa amandla ayo ezinkambisweni eziqhubekayo zezimboni15.

 

Ukukhetha Intambo ye-Nichrome Engakwesokudla

Ukukhetha ibanga elifanele negeji kudinga ukuhlola amazinga okushisa okusebenza, izimo zemvelo, kanye nemininingwane kagesi. Izintambo ezizacile (igeji ephezulu) zifanelana nezidingo zokumelana okuphezulu, kuyilapho izinhlobo eziwugqinsi zisingatha imithwalo yamanje emikhulu15. Ezimweni ezimbi kakhulu, i-nichrome 70 kanye ne-80 inikeza ukuqina okungenakuqhathaniswa, kanti ibhalansi ye-nichrome 20 yezindleko nokusebenza kwamatheminali kagesi9.

 

Ukuphepha Nokusimama

Nakuba ukumelana nokushisa kwe-nichrome kunciphisa izidingo zokunakekelwa, ukuphatha kahle kusabalulekile. Ukushisisa, izilawuli zokushisa, nokuhlola okuvamile kunciphisa izingozi zokushisisa ngokweqile kanye nezingozi zikagesi15. Ngaphezu kwalokho, ukuphila kwayo isikhathi eside nokusebenziseka kabusha kuhambisana nemizamo yomhlaba wonke yokunciphisa udoti wezimboni.

 

Mayelana Nenkampani Yethu
Njengomholi wezixazululo ezithuthukisiwe ze-alloy, sisebenza ngokukhethekile ekukhiqizeni izintambo ze-nichrome ezisebenza kahle eziklanyelwe izinhlelo zokusebenza ezihlukahlukene. Izikhungo zethu ezisezingeni eliphezulu zisebenzisa ubunjiniyela obunembayo kanye nokulawulwa kwekhwalithi okuqinile ukuze kulethwe ama-alloys angaphezu kwamazinga emboni. Kusukela kuzinto zokushisisa zebanga le-aerospace kuya kumiklamo ye-resistor yangokwezifiso, imikhiqizo yethu iqhuba ukuqamba okusha kuyo yonke imikhakha.

Ukuguquguquka okungenakuqhathaniswa kwe-Nichrome wire kuqinisa isimo sayo njengento ebalulekile kubunjiniyela besimanje. Njengoba izimboni zithuthuka, kuzoba njalo nokusebenza kwazo-okugqugquzelwa ukuthuthuka kwesayensi yezinto ezibonakalayo nokuzibophezela ekusimameni. Ukuze uthole izixazululo ezenzelwe wena ze-nichrome ezihlangabezana nezidingo zakho zobuchwepheshe nezokusebenza, xhumana nethimba lethu namuhla.
