Kwixesha apho ukuchaneka, ukuqina, kunye nokusebenza kakuhle kuchazwa inkqubela phambili kwezoshishino,ucingo lwe-nichromeIyaqhubeka nokuma njengesiseko sokuvelisa izinto ezintsha ngobushushu. Iqulunqwe ikakhulu yi-nickel (55–78%) kunye ne-chromium (15–23%), kunye nezixa ezincinci zesinyithi kunye ne-manganese, iipropati ezikhethekileyo zale alloy ziyenza ibe yinto ebalulekileyo kumashishini onke—ukusuka kwizixhobo zasekhaya ukuya kubunjineli beenqwelo-moya. Apha, sihlola ukusetyenziswa okwahlukeneyo kwe-nichrome wire kunye nendima yayo ekubumbeni ubuchwepheshe bokufudumeza banamhlanje.

 

Iipropati Eziphambili Eziqhuba Ukuguquguquka kweNichrome

Ixabiso leNichrome likwibhalansi yayo ebalaseleyo yeempawu zomzimba nezombane. Ngokumelana kwe-1.0–1.1×10⁻⁶ Ω·m kunye nendawo yokunyibilika edlula i-1400°C315, iguqula amandla ombane abe bubushushu ngokufanelekileyo ngelixa ixhathisa i-oxidation kunye nokugqwala naphantsi kweemeko ezinzima. Uhlobo lwayo olungengombane, ukuguquguquka kwayo, kunye nokwanda kobushushu obuphantsi kuyayiphucula ngakumbi indlela ehambelana ngayo315. Ezi mpawu ziqinisekisa ukusebenza rhoqo kwiindawo ezifuna ukuthembeka, ukusuka kwiifeni zoshishino ezinobushushu obuphezulu ukuya kwizixhobo zonyango ezichanekileyo.

 

Usetyenziso oluPhambili lweNichrome Wire

1. Izixhobo zasekhaya

Ucingo lweNichrome lusisiseko sezixhobo zokufudumeza zemihla ngemihla. Iitoaster, izomisi zeenwele, ii-oven, kunye neeketile zombane zixhomekeke kubuchule bazo bokuvelisa ubushushu obukhawulezayo nobufanayo. Umzekelo,i-nichrome 60Isetyenziswa kakhulu kwizixhobo ezishushu ngokulinganayo ezifana neegrill kunye nezifudumezi zokugcina, ngelixa i-nichrome 80 (Ni80Cr20) igqwesile kwizicelo ezinamandla aphezulu ezifana nezifudumezi zamanzi kunye nee-soldering irons ngenxa yokunamathela kwayo okuphezulu kwe-oxide kunye nobude bayo bexesha elide915.

2. Iinkqubo zemizi-mveliso nezemveliso

Kwiindawo zoshishino, ucingo lwe-nichrome lunika amandla izitofu zombane, ii-oven, kunye nezixhobo zokucubungula ubushushu. Ukumelana kwayo nokuqhekeka—ukugcina ukuqina kwesakhiwo phantsi koxinzelelo olude kumaqondo obushushu angaphezu kwama-400°C—kwenza ukuba ilungele ukuqhoboshelwa, ukunyibilika, kunye nonyango lobushushu315. Amashishini afana ne-metallurgy kunye ne-ceramics asebenzisa imicu ye-nichrome kunye neekhoyili ukuze azinze ekunciphiseni i-atmospheres, ephepha iingxaki ezifana “nokubola okuluhlaza” okubonwa kwezinye ii-alloys9.

 

3. Iinkqubo zeenqwelo-moya kunye neeMoto

Ukuthembeka kweNichrome kufikelela kwiindawo ezifuna amandla afana neenkqubo zokususa i-aerospace de-icing, ii-sensors ze-injini, kunye nezifudumezi zekhabhini. Amandla ayo okumelana nokujikeleza kobushushu kunye neemeko ezinzima aqinisekisa ukhuseleko kunye nokusebenza kakuhle kwiindawo ezibalulekileyo15. Ukusetyenziswa kweemoto kuquka izifudumezi zezihlalo kunye neentambo zokunyibilikisa iqhwa, apho iintlobo zeNichrome 30 kunye ne-40 zibonelela ngokufudumala okuhlala ixesha elide nokonga amandla9.

4. Izixhobo zonyango nezeLebhu

Kwinkonzo yezempilo, ucingo lwe-nichrome luvumela ulawulo oluchanekileyo lobushushu kwizixhobo zotyando, ii-heating pads, kunye nezixhobo zokubulala iintsholongwane. Iilabhoratri zisebenzisa ukungangeni kwayo kwiimvavanyo zomlilo kunye nokutsha kwezinto ezisebenza kude, zinciphisa umngcipheko wongcoliseko715.

5. Izinto Ezintsha Ezivelayo kunye Nezisombululo Ezilungiselelweyo

Ukuqhubela phambili kwi-nichrome alloys kugxile ekuphuculeni ukusebenza kakuhle ngokusebenzisa iindlela ezicociweyo kunye neendlela zokwenza. Ukunyibilika kwe-vacuum-induction, umzekelo, kuvelisa amanqanaba afana ne-Ni80Cr20-VI, elungiselelwe izixhobo ze-electrothermal ezithembeke kakhulu3. Ukongeza, indima ye-nichrome kwizixhobo ezisebenzisa amandla ombane kunye neengubo zokutshiza ezishushu zigxininisa amandla ayo kwimisebenzi yezoshishino ezinzileyo15.

 

Ukukhetha iNtambo yeNichrome efanelekileyo

Ukukhetha ibakala elifanelekileyo kunye negeyiji kufuna ukuvavanya amaqondo obushushu okusebenza, iimeko zokusingqongileyo, kunye neenkcukacha zombane. Iingcingo ezincinci (igeyiji ephezulu) zihambelana neemfuno zokumelana okuphezulu, ngelixa iintlobo ezityebileyo zisingatha imithwalo yamandla amakhulu15. Kwiimeko ezigqithisileyo, i-nichrome 70 kunye ne-80 zibonelela ngokuqina okungenakuthelekiswa nanto, ngelixa i-nichrome 20 ilinganisa iindleko kunye nokusebenza kwezikhululo ze-elektroniki9.

 

Izinto eziqwalaselwayo kuKhuseleko noZinzo

Nangona ukumelana nobushushu be-nichrome kunciphisa iimfuno zokugcinwa, ukuphathwa ngokufanelekileyo kusabalulekile. Ukufakwa kwe-insulation, abalawuli bobushushu, kunye nokuhlolwa rhoqo kunciphisa umngcipheko wokushisa kakhulu kunye neengozi zombane15. Ngaphezu koko, ukuhlala ixesha elide kunye nokuphinda kusetyenziswe kwayo kuhambelana nemizamo yehlabathi yokunciphisa inkunkuma yemizi-mveliso.
