Nichrome-silig: sifooyinka iyo codsiyada

technology Modern dhigeysa dalabaadka sare ee waxqabadka qalabka ay dastuurka ku habboon xaaladaha hawlgalka dhabta ah. Mid ka mid ah Alloys teknoolojiyad sare waa nichrome. Fiilooyin iyo qalabka ku jirto, waa adkaysi u hawlgalka xaaladaha colaadeed.

History of daahfurka

daawaha waa xarunta nickel-chromium ah, iyo kala duwanaanta ku dar bir ah, manganese, aluminium iyo Silicon.

Asal ahaan waxaan lahaa laba siyaabood oo ka soo jeedo. Rujin cilmi sayniska duurka ku of Biraha alloying iyo bedelayaan xoolahooda. Ni iyo CR - qaybood ah oo tayo sare leh daxalka u adkaysta iyo kulayl steels u adkaysta.

Sida daawaha laba qaybaha kala duwan ee nickel iyo chromium, waxaa la ogaadey in 1906 ee USA. Maanta codsan beddelka kala duwan, oo ay ku jiraan saddex-birta ku salaysan.

guryaha Key

Qoraalkani wuxuu ku for qalabka kululaynta casriga ah ee qoyska iyo isticmaalka warshadaha shaki la'aan waa silig nichrome. hantida la kulmo shuruudaha farsamada ugu sareeya.

1. resistivity korontada gudahood 1100-1400 Ohm * m.
2. barta barafku - oo ku saabsan 1400˚S, jidaynayey si ay u shaqeeyaan 800-1100˚S. Yaree hawlgalka ku xiran tahay kooban. Sidaas darteed, content bir ah waxa ay yaraynaysaa in 850-900˚S, waayo binary saafi ah waa 1100˚S.
3. Mugga 8000-8500 kg / m ^3.
4. xoog High (σ _ee = 650-700 MPA); Tilmaamayaasha kaydiyaa hoos deegaanka xoqe acidic iyo heerkulka badan.
5. ductility Good wada qalbi engegnaantiinna aawadeed jibbaaranaha u oggolaanaysa in uu diidanaa iyo barbaro.

Tilmaamo soocayaa

Waxaa ka mid ah waxyaabaha korontada ugu caansan suuqa - Nichrome silig. resistivity ee qayb ka this ka mid ah qalabka kululaynta korontada si gaar sare, kuu ogolaanaya in aad u leedahay baahida ballaaran.

Muqaalka muhiimka ah ee biraha waa ay iska caabin ah si ay qayilo heerkulka sare iyo xoqe ku hoos jira xaalad caadi ah. kaalin muhiim ah waxaa halkan ciyaaray chrome. Cunsurka ka dhigan dusha u dhiganta film xabagta ah, taas oo qabata shaqada ka ilaaliya. Waa masuul ka ah wax u dhigma madow midab oo la bedelay ka caan cad-cawlan inta lagu jiro ka kaxayntu ay si farsamaysan ee lakabka oxidized.

Waxaa xusid mudan in xiriir toos ah la acids weli Halaagtay, xitaa ka sii badan tungsten daxalka u adkaysta ah.

daawaha Laba-qayb wuxuu leeyahay sifooyin magnetic. Waxay dhacaan beddelka badan, laakiin ay wiiqeen waxqabadka.

silig Nichrome waa Patriots, aan si fudud loo saamayn kara awoodda.

Nidaaminta macluumaad ku saabsan sida si loo ogaado silig Nichrome, inta badan sida loo kala saaro alaabta dibadda ama la mid ah,

1. biraha cusub ee White, mugdi - hore horumariyo.
2. Taban ama dayac magnetic.
3. Rigidity.
4. Burburin by acids, xasiloonida qayilo sarkhaansan yihiin heerkulka sare.

Magac ku tilmaamay

noocyada kala duwan ee hadda jira oo sideeda, bandhig kala duwan daawaha Nichrome. silig waxa uu leeyahay isticmaalka baahsan, wixii la goostay by sifooyinka gaarka ah ee kasta.

• Group 1 - wax resistor: H20N80, H20N73YUM-VI, VI-N80HYUD, H15N60.
• Group 2 - xubno ka kululaynta Birta loo isticmaalo guryaha iyo warshadaha oo leh sifooyin sare ee iska caabin ah kulaylka: H20N80-H-VI, H15N60-N, N-HN70YU, H20N80-H HN20YUS.
• Group 3 - hawlgalka marka heerkulku kor 900˚S: N50K10, Kh25N20.

Dhexroor ee silig Nichrome kooxda koowaad waa 0,009-0,4 mm, iyo tan labaad - 0,2-7,5 mm.

"Xigaalo" waa Cantal ama fehrali - Alloys chromium, aluminium iyo bir. Waxa kale oo lagu gartaa resistivity korontada sare, caabiga kulaylka gudahood 1250-1400˚S, laakiin aan la isku hallayn, inkastoo qiimaha hooseeyo (H23YU5, H13YU4, H23YU5T, H27YU5T, H15YU5).

deciphering stamps

Guryaha iyo codsiga ah ee badeecadaha ka soo jeeda nichrome waxaa go'aamiya Halabuurka kiimikada ay. Tixgeli kuwa ugu muhiimsan.

• H20N73YUM-VI: chromium - 20% nickel - 73% aluminium - 3% molybdenum - 1.5% manganese - ilaa 0.3% titanium - 0.05%, birta - 2%, carbon - si 0.05%; dhalaalay leh habka induction vacuum ah;

• HN20YUS: CR - 20%, Ni - 20%, Al - 1%, amayno - ilaa 0.2%, Ca - ilaa 0,1%, Si - 2,5%, Fe - 50%, C - 0, 08% - kululeeyayaasha for Foornooyinka warshadaha.

noocyada kala duwan ee wax soo saarka

Selection of daawaha kasta oo ah waxa lagu gartaa astaamo tiknoolaji iyo farsamo oo tayo sare leh, waa in aad gun iyo nidaaminaya. Gaar ahaan marka ay timaado in qiimaha sare. Sayidka a-farsamada casriga ah iyo qalab qaali ah waa silig nichrome. GOST 8803-89, 12766.1-90, 12766.3-90, 12766.4-90 qeexayaa shuruudaha, muuqaalada iyo codsiyada sixitaanka. Iyadoo la tixraacayo heerarka iyo ku xiran tahay sifooyinka wajiga, biraha la soo bandhigay for sale ee foomka of silig ama cajalad, doorashada taas oo ku xiran dhexroorka, iskutallaabta qaybta, dhererka, isticmaalka gaarka ah.

Ilo ku haboon la duubay oo loogu talagalay warshadaha zagzaagga cajalad saarka, silig, namana daaliyaan.

faahfaahinta Product

Marka aad dooranayso waxyaabaha ka nichrome waa muhiim in la tixgeliyo sifooyinka soo socda:

• resistivity magacaaban,
• dhexroor, qaybta cross oo miisaankeedii dhan yahay;
• impedance iyo heerkulka hawlgalka safafka dhabta ah taas oo ku xidhan oo xuduudaheedu jirka.

The qiyamka magacaaban oo ka mid ah sifooyinka parametric aasaasiga ah waxaa go'aamiya GOST iyo ay ku xiran tahay darajada iyo Halabuurka.

Nichrome silig-dhexroor go'aamiso ay cross-section oo u dhiganta miisaan skein iska caabin Ujeedada.

Sayidka, miisaanka silig (nichrome) 100 mitir wax soo saarka waa si toos ah saamiyeed si ay size, iyo dhexroor iyo aagga qeybaha - waa dhigmayn in ay iska caabin dhabta ah.

heerkulka hawlgalka waxay ku xiran tahay ma aha oo kaliya on Halabuurka kiimikada, laakiin sidoo kale on sifooyinka parametric.

Dhexroor ee silig lagu soo saaray by saarayaasha, waa gudahood 0,05-12 mm iyo cajalado - mm 0,15-3,2.

codsiga

Tayada mar walba xaq yahay kharashka. Isla sidaas u dhaqmaan daawaha Nichrome. Wire iyo strips ee wax this hubkaas ayaa loo isticmaalaa in meelaha wax biraha kale ma laga yaabaa inuu bedelo. High iska caabin korontada, iska caabin ah lagu qayilo, guryaha farsamo oo tayo sare leh, oo ay ku jiraan deegaanno xoqe, xaaladaha hawlgalka heerkulka sare - Waxaas oo dhan waxaa loo isticmaali karaa in beeraha kala duwan.

In warshadaha:

• Thermocouples Foornooyinka korontada metallurgic.
• xubno Dhismayaasha qalabka biraha-barafka induction.
• qalajiyo hawo Warshadaha.
• Qaybo ka mid ah kululeeyaha iyo exchangers kulaylka.
• soo-saarka korontada: resistors iyo rheostats.
• electrodes qaarkood ee alxanka.
• Single iyo multi-kaari fiilooyinka korontada.

Waa qayb ugu weyn ee dhismaha oo dhan qalabka casriga ah,

• xubno ka kululaynta in dharyo sugan korontada, kululeeyayaasha biyaha, kululeeyaha, kululeeyayaasha.
• xubno ka kululaynta ee qalajiya timaha, birta laad, birta.

Waxaa laga yaabaa in qiimaha - khasaare oo kaliya wax Nichrome. Wire nooca bicomponent nickel-chromium noqon doonaa mid qaali ah oo dheeraad ah. content The bir ah oo tiro hoos u nickel, markeeda, nidaaminaya qiime hoose, hase ahaatee ma bixiyaan fursado ah in Cr20Ni80. Doorashada waxay ku xiran tahay shuruudaha farsamo.

waxyaabaha Doorashada ka nichrome dhab shaqeeyaan macluumaadka on Halabuurka kiimikada oo xiiso in brand ah, ay conductivity korontada iyo iska caabin ah, astaamaha jirka ah ee dhexroorka, dhererka cross-qeybaha ka. Si weyn u xiiseyneysa in dukumentiyada ku habboon, iyo sidoo kale in ay awoodaan in aragga kala saaro daawaha ka "tartamaya" ay. Si habboon u soo xulay wax - fure u ah isku halaynta ee qalabka iyo technology ee ay hawlgelinta.
