Nichrome-wire: iimpawu kunye nezicelo

Ngenxa yeteknoloji ekhoyo, kudinga ekusebenzeni izixhobo enqila afanayo iimeko yokusebenza uqobo. Enye aluminium eziphakamileyo-zobugcisa yi nichrome. Iingcingo kunye nezixhobo eziqulathe kuyo, abanganyangekiyo iimeko operation ezikhohlakeleyo.

History of izovela

Ingxubevange yi-nickel-chromium ezimbaxa, yaye iinguqulelo bongeze intsimbi, manganese, aluminiyam kunye lesilicon.

Ekuqaleni ndaba iindlela ezimbini imvelaphi. Isekelwe kuphando lwezenzululwazi entsimini zesinyithi alloying kwaye uguqulo kancincane iimpawu zazo. Ni ne Cr - amacandelo nokudliwa ngumhlwa ukumelana nobushushu yodidi enganyangekiyo ezikumgangatho ophezulu.

Njengoko i-component ezimbini ingxubevange nickel kunye chromium, kwafunyaniswa ngo-1906 e-USA. Namhlanje Faka iinguqulelo kancinane ezahlukeneyo, kuquka i-yentsimbi ezintathu-based.

iipropati key

Izinto for zombane ukufudumeza mihla indlu kunye nokusetyenziswa mveliso ngokungathandabuzekiyo wire nichrome. iimpawu zayo ukuhlangabezana neemfuno aphezulu zobugcisa.

1. resistivity Electrical ngaphakathi 1100-1400 Ohm * m.
2. Lokunyibilika - malunga 1400˚S, ukuvumela ukuba lusebenzise 800-1100˚S. Liqingqiweyo ukusebenza kuxhomekeke nokwakheka. Ngenxa yoko, isiqulatho intsimbi nciphisa ukuba 850-900˚S, kuba okubini esulungekileyo ngayo 1100˚S.
3. Density 8000-8500 kg / m ^3.
4. amandla High (σ _e = 650-700 MPA); Iimpawu agcinwe phantsi bume asidi bako kunye lobushushu omkhulu.
5. ductility Good kunye yobulukhuni bomtya ivumela zokuqalisa nokuzoba.

iimpawu ezinika

Phakathi iimveliso zombane uthandwayo kwi emarikeni - Nichrome wire. Le resistivity ngayo eli candelo le zombane zokufudumeza yombane eziphakamileyo kakhulu, ekuvumela ukuba imfuno ngokubanzi.

Inkalo ebalulekileyo but is ukuxhathisa yayo ubushushu igcwala eliphezulu onakalisayo phantsi kweemeko eziqhelekileyo. A indima ephambili udlalwa apha Konqueror. Isiqalelo eyenza umgangatho ihambelana umboniso oxide, nto leyo ezisebenza umsebenzi olukhuselayo. Ngayo uxanduva ehambelana izinto umbala emnyama ukuba indawo luphawu emhlophe-izimvi ngexesha nokususwa ngomatshini esibekwa oxidized.

Kubalulekile ukuphawula ukuba ukudibana ngqo asidi nangoku uyawutshabalalisa, nkqu nangaphezu Tungsten emelana nokudliwa ngumhlwa.

-Component ezimbini ingxubevange na iipropati ngemagnethi. Bona kwenzeka ngenxa uguqulelo ezininzi, kodwa buthathaka yokusebenza.

wire Nichrome-gingxi, akakwazi lula ngamandla.

Nokumisa ulwazi malunga ukujonga ukuba izixa-wire Nichrome, ikakhulu ukwahlula njani ngezinto zangaphandle okanye efanayo:

1. metal White entsha, ezimnyama - ngaphambili kuphuhliswa.
2. Negative okanye kudume ngemagnethi.
3. Nokoma.
4. Imbubhiso asidi, uzinzo igcwala phantsi kwempembelelo amaqondo obushushu aphezulu.

nokuhlelwa sokuthengisa

brand ezikhoyo zahluke kumafa, coca uluhlu ingxubevange Nichrome. Kwicingo uba ukusetyenziswa, nto leyo umiselwa iimpawu ngabanye ngamnye.

• Group 1 - impahla resistor: H20N80, H20N73YUM-VI, VI-N80HYUD, H15N60.
• Group 2 - Metal ukufudumeza izinto ezisetyenziswa emakhaya zoshishino kunye neempawu ephezulu yokunganyangeki ubushushu: H20N80-H-VI, H15N60-N, N-HN70YU, H20N80-H HN20YUS.
• Group 3 - ukuba umsebenzi kwiqondo lobushushu phezulu 900˚S: N50K10, Kh25N20.

Ubukhulu be locingo Nichrome zeqela lokuqala 0,009-0,4 mm, kwaye eyesibini - 0,2-7,5 mm.

"Nakwelokuzalwa" ezi Cantal okanye fehrali - aluminium chromium, aluminiyam nesinyithi. Kananjalo ebonakala resistivity ophezulu umbane, ukumelana ubushushu ngaphakathi 1250-1400˚S, kodwa oluthembekileyo ngaphantsi, nangona ixabiso ephantsi (H23YU5, H13YU4, H23YU5T, H27YU5T, H15YU5).

ziqonde izitampu

Iimpawu kunye nokusetyenziswa kweemveliso ukusuka nichrome zigqitywa ngezithako zawo chemical. Cinga ezona ziphambili.

• H20N73YUM-VI: chromium - 20% nickel - 73% aluminiyam - 3% molybdenum - 1.5% manganese - ukuya kwi-0.3% titanium --0.05%, intsimbi - 2%, carbon - ukuya 0.05%; zanyibilika indlela cleaner induction;
• HN70YU-H: Kr - 27%, Ni - 70%, Al - 3%, MN - ukuya kwi-0,3%, Cs - ukuya 0,03%, Ba - ukuya ku 0.1%, Fe - 1.5% , C - 0.1%; beengxenye ukufudumeza yombane;
• HN20YUS: Cr - 20%, Ni - 20%, Al - 1%, Zn - ukuya ku 0,2%, Ca - ukuya ku 0.1%, Si - 2,5%, Fe - 50%, C - ku-0, 08% - Izifudumezi for emlilweni industrial.

iindidi zemveliso

Ukukhethwa nayiphi intsila esibonakala ngeempawu zobugcisa mechanical kwizinga eliphezulu, kufuneka nisekelwe kulawulwa. Ingakumbi xa kuziwa kwi iindleko eziphezulu. Ngoko ke eliphezulu-zobugcisa kunye nezinto zexabiso na wire nichrome. GOST 8803-89, 12766.1-90, 12766.3-90, 12766.4-90 uchaza iimfuno, iimpawu kunye izicelo zokumakisha. Ngokungqinelana nemigangatho ixhomekeke kwiifitsha zobuso, intsimbi inikwa ezithengiswayo ngohlobo wire okanye tape, ukhetho leyo ixhomekeke ubukhulu, icandelo umnqamlezo, ubude, ukusetyenziswa ethile.

Umthombo esifanelekileyo liqengqwa for industrial lemveliso tape ngokugosogoso, wire ezibhijeleyo.

Product incazelo

Xa ukhetha iimveliso ukusuka nichrome kubalulekile ukuba siqwalasele iimpawu zilandelayo:

• resistivity ngegama;
• ububanzi, icandelo emnqamlezweni kunye ubunzima;
• eyona ukuvimba kunye nobushushu yokusebenza zibe kuxhomekeke emzimbeni iparameters.

Amaxabiso obungu iimpawu ezisisiseko parametric zigqitywa GOST kwaye zixhomekeke grade kunye nokwakheka.

Nichrome wire-ubukhulu igqiba wayo cross-candelo kunye ohambelana ubunzima skein nokumelana njongo.

Ngenxa yoko, ubunzima wire (nichrome) 100 imveliso meters kisekiyo ngqo kubungakanani bayo, kwaye ubukhulu kunye indawo yecandelo - na bomzimba ngokomlinganiselo uxhathiso eyiyo.

Iqondo lobushushu yokusebenza kuxhomekeke kuphela kulwakhiwo imichiza, kodwa kwiimpawu parametric.

Ubukhulu be wire ukuba eziveliswa abavelisi, kuba ngaphakathi 0,05-12 mm kunye neeteyiphu - mm 0,15-3,2.

isicelo

Umgangatho njalo hlamusela iindleko. Kukwasebenza kwanjalo kuyo ingxubevange Nichrome. Ucingo kunye imicu eli zokufunda ezisetyenziswa kakhulu kwiingingqi apho naziphi na ezinye iintsimbi ayikwazanga indawo kuzo. High ukumelana zombane, ukumelana igcwala, ezikumgangatho ophezulu Iipropati mechanical, kuquka bume bako, iimeko zokusebenza lobushushu eliphezulu - konke oku zingasetyenziswa kwiinkalo ezahlukeneyo.

Kushishino:

• Thermocouples emlilweni metallurgic zombane.
• isakhiwo ukuba izixhobo metal-ukunyibilika kuFacebook.
• umoya yokomisa Industrial.
• Amalungu boilers kunye sokufudumeza.
• Imveliso Electrical: resistors kunye rheostats.
• Ezinye electrode ye welding.
• Abangatshatanga yaye multi-Umqhubi Iingcingo zombane.

Yeyona licandelo engundoqo noshowo zonke izixhobo zale mihla:

• elementi e oongxawu zombane, izifudumezi zamanzi, boilers, izifudumezi.
• elementi e notsala iinwele, ayini ukugoba, ngeentsimbi.
• amakhandlela kunye neenkqubo zokufudumeza Automotive.
• ugwayi Electronic.

Mhlawumbi ixabiso - ethile kuphela izinto Nichrome. Waya uhlobo bicomponent nickel-chromium kuza kubiza kakhulu. Umxholo zentsimbi kunye nezixa yehlise nickel, nayo, ulawule ngexabiso eliphantsi, kodwa musa ukunika amathuba Cr20Ni80. Ukukhetha kuxhomekeke kwiimfuno zobugcisa.

iimveliso Ukukhetha ukusuka nichrome eneneni asebenza kunye ingcaciso umchiza nokwakhiwa umdla uphawu, conductivity yayo zombane ukuxhathisa, iimpawu zomzimba le ubukhulu, ubude cross-yecandelo. Kuyaphawuleka abanomdla amaxwebhu afanelekileyo, kwakunye ukuba akwazi ukwahlula abangaboniyo ingxubevange ukusuka 'okhuphisana "yayo. isitshixo ukuthembeka kwezixhobo kunye nobuchwepheshe yothethathethwano wayo - kakuhle izinto ekhethiweyo.
