Nichrome kauv: yam ntxwv, daim ntawv thov

Nichrome yog invented nyob rau hauv 1905 los ntawm Albert Marsh, uas txuas npib tsib xee (80%) thiab chromium (20%). Niaj hnub no muaj txog kaum kev hloov kho ntawm alloys ntawm ntau yam qib. Raws li ntxiv dopants ntxiv txhuas, manganese, hlau, pob zeb ntais, titanium, molybdenum, thiab t. D. Vim nws zoo heev zoo no hlau tau lug siv rau zus tau tej cov hluav taws xob engineering.

Basic zoo Nichrome

Nichrome yog sib txawv:

• kub siab kuj. nws txhua yam khoom tsis hloov thaum muaj kev kub kub;
• plasticity, uas tso cai rau zus tau tej cov ib tug hlau Nichrome kauv hlau, ribbon, filament;
• tsis ntawm kev. Cov khoom ua los ntawm Nichrome zoo welded, stamped;
• siab kuj mus corrosion nyob rau ntau yam kev kawm.
• siab kuj nichrome.

Ntsiab zog

• Cov kev ceev ntawm 8200-8500 kg / m3.
• Melting point nichrome - 1400 C.
• Maximum Kev khiav hauj lwm kub - 1100 ° C.
• Durability - 650-700 MPa.
• Lub resistivity nichrome 1,05-1,4 ohms.

Npav Nichrome hlau

Nichrome hlau - lub zoo meej khoom rau ib tug ntau yam ntawm hluav taws xob cua kub hais, uas yog siv nyob rau hauv yuav luag tag nrho cov lag luam. Yuav luag txhua txhua yim tsev rhaub muaj ntsiab ua los ntawm nichrome.

Code tsab ntawv hlau:

• "N" - yog feem ntau yog siv nyob rau hauv cov cua kub hais.
• "C" - yog siv nyob rau hauv kuj hais.
• "KAUM" - yog npaj rau tubular hluav taws xob tso cua sov.

Raws li rau lub teb chaws cov qauv, muaj ntau ntau loj hom:

• Ob chav hlau Cr20Ni80. Muaj pes tsawg leeg ntawm lub alloy muaj xws li: npib tsib xee - 74% chromium - 23% thiab 1% ntawm cov hlau, pob zeb ntais thiab manganese.
• Triple H15N60. Cov hlau muaj 60% npib tsib xee thiab 15% chromium. Qhov thib peb tivthaiv - iron (25%). hlau hlau saturation yuav txo tau tus nqi ntawm nichrome, tus nqi ntawm uas yog heev siab heev, thaum tswj nws cov tshav kub tsis kam. Nyob rau hauv tas li ntawd, nws tsub kom nws workability.
• Cov uas pheej yig tshaj kev xaiv Nichrome - Kh25N20. Qhov no hlau-nplua nuj hlau nyob rau hauv uas tus neeg kho tshuab cov khoom fwm, tab sis cov ua hauj lwm kub yog tas rau 900 ° C.

Kev siv cov nichrome

Vim nws zoo thiab nws tus yam ntxwv ntawm nichrome khoom yuav tau mus thov qhov twg tsim nyog cia siab rau, durability, ua hauj sib txhoj puab heev ib puag ncig thiab heev kub.

Nichrome kauv thiab hlau yog ib feem ntawm yuav luag tag nrho cov hom ntawm cov cua kub kiag li lawm. Nichrome yog tam sim no nyob rau hauv lub ci qhob cij, bakeries, cua sov, ncu. Cov hlau kuj muaj nyob rau daim ntawv thov nyob rau hauv resistors thiab kev khiav hauj lwm nyob rau hauv huab cua kub. Muaj Nichrome thiab ib tug hluav taws xob teeb thiab ib tug soldering hlau. Nichrome kauv muaj loj kuj thiab tshav kub tsis kam, uas tso cai rau lawv siv nyob rau hauv kub furnaces kom qhuav thiab firing.

Yog siv thiab scrap Nichrome. Nws melted down, thiab cov khoom mus rov qab mus rau hauv lub lag luam. npib tsib xee-chromium hlau siv nyob rau hauv cov tshuaj laboratories. Qhov no muaj pes tsawg leeg tsis hnov mob nrog rau feem ntau acids thiab alkalis. Deformed cua kub Nichrome kauv yog siv nyob rau hauv hluav taws xob yeeb.

Muab piv nrog rau yav tas los siv rau lub hom phiaj no hlau, Nichrome cov khoom uas muaj kev nyab xeeb, tsis muaj, tsis xeb, tsis muaj lub spliced feem.

Melting point nichrome 1400 ° C, ces thaum ua noj ua haus yog tsis muaj tsw thiab cov pa.

Engineers tseem soj qab qhov cim thaj chaw ntawm no cov ntaub ntawv uas, lossi expanding lub Scope ntawm nws daim ntawv thov.

Tom tsev, lub Nichrome hlau yog siv rau qhov siv thiab ua lub tsev ua khoom, jigsaws thiab cutters, xws li, piv txwv li, siv ib lub tshuab rau tej ua npuas ncauj los yog ntoo, ib tug soldering hlau, ib tug ntaus ntawv rau hlawv ntoo, vuam tshuab, domestic cua sov, thiab thiaj li nyob. D.

Cov feem nrov thiab suav hais tias yog hlau Cr20Ni80 H15N60.

Kuv yuav yuav Nichrome hlau

Yuav ua raws li ntawm cov khoom no yog ua nyob rau hauv coils (coils, coils) los yog nyob rau hauv daim ntawv ntawm ib daim kab xev. Tus ntoo khaub lig seem ntawm ib tug nichrome hlau yuav ua tau nyob rau hauv daim ntawv ntawm ib lub voj qe, ib lub voj voog, ib tug square thiab ib tug Trapezoid, txoj kab uas hla yog nyob rau hauv ntau ntawm 0.1 mus rau 1 millimeter.

Qhov ua peb tau los yog yuav khoom los ntawm nichrome? Peb xav kom tau xav txog cov feem ntau ntau thiab tau kev xaiv:

1. Ua ntej ntawm tag nrho cov, koj muaj peev xwm hu tau rau lub koom haum, ua cov khoom thiab rau txim. Nrhiav kom paub cov caij nyoog chaw nyob ntawm tej qhauj yuav ua tau nyob rau hauv tshwj xeeb siv rau khoom thiab cov kev pab uas yog muaj nyob rau hauv yuav luag tag nrho cov loj lub zos thiab lub zos. Cov neeg teb xov tooj yuav tsum tau qhia rau kuv qhov twg mus yuav, thiab muab ib tug xov tooj. Nyob rau hauv tas li ntawd, cov lus qhia txog cov chav tej khoom muaj nyob rau hauv lub official websites ntawm manufacturers.
2. Muas Nichrome khoom nyob rau hauv tshwj xeeb khw muag khoom noj yuav ua tau, piv txwv li, muag xov tooj cua Cheebtsam, cov ntaub ntawv uas kev nyuab xws li "skilful txhais tes" thiab thiaj on. D.
3. Yuav los ntawm tsoom neeg muag cov xov tooj cua chaw, spare qhov chaw thiab lwm yam hlau cov khoom.
4. Nyob rau hauv txhua muag khoom kho vajtse.
5. Nyob rau hauv lub lag luam koj yuav tau tej qub tsev, piv txwv li kuaj rheostat, thiab coj Nichrome.
6. Nichrome hlau kuj muaj nyob hauv tsev. Piv txwv li, nws yog tsim los ntawm spiral hotplate.

Yog hais tias koj xav mus ua ib tug loj kev txiav txim, ces tus tsim yog tus xaiv thawj. Yog hais tias koj xav tau ib tug me me npaum li cas ntawm Nichrome hlau, tag nrho lwm daim ntawv teev cov khoom yuav tsum tau pom nyob rau hauv cov ntaub ntawv no. Thaum twg koj yuav yuav tsum nco ntsoov xyuam xim rau cov cim.

Nichrome kauv coiling

Niaj hnub no Nichrome kauv yog ib qho tseem ceeb ntawm ntau tso cua sov. Tom qab txias lub Nichrome yog tau tuav nws plasticity, ua lub kauv ntawm xws li ib tug cov ntaub ntawv uas muaj peev xwm muab tau yooj yim muab tshem tawm los hloov nws zoo los yog, yog tias tsim nyog, kho kom tsim nyog qhov luaj li cas. Muab Kauv Winding yog nqa tawm nyob rau hauv industrial tej yam kev mob ib qho automatic txoj kev. Tom tsev, koj yuav tau nqa tawm ib phau ntawv winding. Cia peb xav txog yuav ua li cas yuav ua rau nws.

Yog hais tias nws tsis yog ib yam nkaus thiab tseem ceeb tsis yog tas Nichrome kauv nyob rau hauv nws cov hauj lwm mob, thaum winding yuav khom, li ntawd, yuav hais lus, "los ntawm lub qhov muag". Ua li no, xaiv cov yam tooj lem nyob rau hauv lub cua sov nichrome hlau, lub kauv xws li tseg rau lub network, thiab ua los yog zuj zus lawm lub xov tooj ntawm koj lem. Qhov no winding txoj kev yog heev yooj yim, tab sis nws muaj peev xwm coj ib tug ntev lub sij hawm, thiab ib feem ntawm Nichrome li lub sij hawm.

Yuav kom txhim kho txoj kev yooj yim thiab raug ntawm kev xam ntawm lub kauv winding, koj muaj peev xwm siv ib tug tshwj xeeb hauv internet tswvyim.

Xam qhov yuav tsum tau tus xov tooj ntawm koj lem yog tau mus pib winding rau tus pas nrig. Tsis txiav cov hlau yuav tsum tau ua tib zoo kev cob cog rua nichrome kauj mus rau ib tug voltage qhov chaw. Ces mus saib lub correctness ntawm cov lus teb ntawm lub kauv winding. Nws yog ib qho tseem ceeb los ua tim nyob rau hauv lub siab hais tias qwj gated winding ntev yuav tsum tau nce los ntawm ib tug thib peb nyob rau hauv lub xam ntawm lub resulting qhov tseem ceeb.

Xav kom cov tib ncua deb ntawm nyob ib sab lem ntawm lub winding yuav tsum tau muab nyob rau hauv ob nyob ntawm tej - ib tug nichrome, lub thib ob - yog tooj liab los yog txhuas, nrog ib lub cheeb uas yog sib npaug zos rau cov kev kawm clearance. Thaum winding yog tshaj, tus pab hlau yuav tsum tau ua tib zoo cua.

Tus nqi ntawm cov nichrome

Lub tsuas drawback, uas muaj ib tug Nichrome - tus nqi. Piv txwv li, ib tug binary hlau thaum muas khw muag khoom yog kwv yees li ntawm txog 1,000 rubles ib kilogram. Tus nqi ntawm ib tug Ligature tias Nichrome - txog 500-600 rubles.

xaus

Nrog rau zus tau tej cov npib tsib xee-chromium, nws yog tsim nyog los noj mus rau hauv tus account cov ntaub ntawv nyob rau hauv lub tshuaj nyob tus yeees ntawm cov khoom ntawm kev txaus siab, thiab nws cov hluav taws xob kuj, yam ntxwv lub cev ntawm txoj kab uas hla, ntoo khaub lig-section, ntev thiab thiaj li nyob. D. Nws tseem yog ib qho tseem ceeb mus nug cov ntaub ntawv. Tsis tas li ntawd, koj yuav tsum tau mus visually paub qhov txawv nws los ntawm cov hlau, li ntawd, yuav hais lus, "competitors". Kom cov ntaub ntawv uas xaiv yog tus yuam sij hluav taws xob ntseeg.
