Rau kev lag luam pas nrig tooj liab, nws txaus los nyeem cov kab lus no
Taw qhia: kuv lub teb chaws tus pas nrig tooj liab tau siv li ntawm 13% ntawm tag nrho cov khoom siv hauv khw. Cov pas nrig tooj liab tau dhau los ua kev lag luam uas tsis tuaj yeem tsis quav ntsej thaum kawm txog kev lag luam tooj liab. Tsab ntawv xov xwm no txheeb xyuas cov pas nrig tooj liab kev lag luam los ntawm kev xav ntawm tooj liab pas nrig siv tshuab, kev siv cov qauv, thiab kev tsim khoom ntawm cov lag luam loj hauv tsev. kuaj nws tawm.
Taw qhia txog tooj liab pas nrig
Copper pas nrig yog ib hom uas tsis yog-ferrous hlau ua pas nrig uas muaj hluav taws xob conductivity. Feem ntau muab faib ua tooj dag thiab tooj liab rods. Siv nyob rau hauv cov kav dej thiab chav dej accessories, kho vajtse, li qub, marine twj, atomizer structural qhov chaw, kev sib txhuam accessories, thiab lwm yam.
Copper qws khoom qauv
Cov khoom siv tooj liab muaj xws li H59, H59-1, H59-2, H59-3, H60, H60-2, H62, H63, H65, H68, H70, H80, H90; C1100, C1020, C2680, C2800, C2600, C2801, C5191, C5210, C2200, C7521, C7541, C17200, C1070, C7701, QSn6.{{28Sn}.{3. 32}}.3, BZn18-18, BZn15-20, CuBe2, thiab lwm yam.
Copper pas nrig txoj kev
Muaj peb txheej txheem rau kev tsim cov pas nrig tooj liab, raws li hauv qab no:
1. Extrusion-(rolling)-drawing-(annealing)-cov khoom tiav-cov khoom tiav.
2. Nruam casting (nce toj casting, kab rov tav los yog log hom, crawler hom, dipping) - (rolling) - kos duab - (annealing) - xov - khoom tiav.
3. Nruam extrusion-stretching-(annealing)-cov khoom tiav-cov khoom tiav.
Copper pas nrig txoj kev
extrusion
1. Hom extrusion
(1) Forward extrusion: yog hais txog tus cwj pwm extrusion nyob rau hauv uas extrusion kev taw qhia ntawm cov khoom yog tib yam li cov kev taw qhia ntawm extrusion quab yuam.
(2) Rov qab extrusion: yog hais txog extrusion tus cwj pwm nyob rau hauv uas extrusion kev taw qhia yog opposite rau extrusion quab yuam kev taw qhia.
(3) Tshwj xeeb extrusion: yog hais txog lwm txoj kev extrusion xws li hydrostatic extrusion.
2. Cov yam ntxwv ntawm extrusion
(1) Cov yam ntxwv ntawm kev xa tawm mus rau pem hauv ntej: Cov khoom siv rau pem hauv ntej extrusion yog qhov yooj yim thiab yog siv dav tshaj plaws.
(2) Cov yam ntxwv ntawm kev thim rov qab extrusion: Rov qab extrusion txo qhov kev sib txhuam ntawm cov ingot thiab cov extrusion chim, txo cov extrusion quab yuam, thiab tuaj yeem txhim kho lub neej ntawm cov cuab yeej. Nws yog dav siv nyob rau hauv me me thiab nruab nrab-qhov loj me extruded khoom.
(3) Cov yam ntxwv tshwj xeeb extrusion: Tshwj xeeb extrusion feem ntau yog siv rau extrusion ntawm cov khoom tshwj xeeb.
dov
Muaj peb hom tooj liab bar dov: hla dov, spinning dov thiab planetary dov.
1. Hla dov: Ntawm ob-yob los yog peb-yob zeb, ib txoj kev ntawm longitudinal dov ntawm ntau hom ntaub ntawv raws li qhov dhau los ntawm cov dov grooves ntawm cov yob.
2. Spinning dov: Lub rotating hlau disc los yog preformed dawb paug yog pub los ntawm ib tug rotating log thiab spun rau hauv cov duab.
3. Planetary dov: Ib txoj kev dov rau extruding ntau hom profiles ntawm ib lub rolling mills uas muaj ib los yog ob qho kev txhawb nqa rollers thiab ntau lub planetary rollers nyob ib puag ncig cov kev txhawb nqa rollers.
stretch
1. Lub ntsiab lus ntawm kev ncab: Kev ncab yog txoj kev ua haujlwm siab uas hla qhov khoob ntawm qhov tuag thiab siv qhov nro los hloov nws cov duab thiab qhov loj. Nws kuj yog ib txoj hauv kev tseem ceeb rau kev ua tiav tooj liab pas nrig-hom hlau rods.
2. Cov yam ntxwv ntawm kev ncab: Los ntawm cov txheej txheem no, cov duab thiab qhov loj ntawm cov khoom tuaj yeem ua tau raws li qhov yuav tsum tau ua, thiab nws muaj cov yam ntxwv ntawm qhov siab qhov tseeb thiab qhov chaw zoo.
3. Kev faib cov khoom siv stretching
Feem ntau siv cov khoom siv stretching xws li saw stretching tshuab, disc stretching tshuab, hydraulic stretching tshuab thiab ua ke stretching tshuab. Chain stretching tshuab yog tsuas yog siv rau stretching ncaj cov khoom, thiab muab faib ua ib tug saw, ob chav saw, ib kab thiab ntau-kab stretching tshuab. Disc stretching tshuab yog tsuas yog siv rau zus tau tej cov me me thiab nruab nrab txoj kab uas hla discs. Lub tshuab sib xyaw ua ke feem ntau tsim cov khoom me me uas hloov los ntawm cov voj voog ncig mus rau cov khoom ncaj nraim. Nws muaj peev xwm ib txhij paub txog stretching, straightening, nto polishing, taag-ntev shearing, thiab lwm yam ntawm cov khoom, thiab ncaj qha tsim cov khoom tiav.
Kev kho cua sov
Kev kho cua sov ntawm lub raj thiab pas nrig hlau rods yog feem ntau nruab nrab annealing thiab tiav cov khoom annealing. Cov txheej txheem annealing yog tsim raws li cov yam ntxwv ntawm cov khoom, cov khoom lag luam, thiab cov kev xav tau ntawm kev ua haujlwm. Tam sim no, tswb furnaces, roller hearth furnaces, thiab mesh saw furnaces nrog cov cua tshwj xeeb yog dav siv rau kev kho cua sov ntawm cov raj thiab pas nrig. Thaum siv cov huab cua tiv thaiv, kev ncig ntawm cov huab cua tau ntxiv dag zog kom ntseeg tau tias cov huab cua tsis sib xws thiab qhov ci ntsa iab ntawm cov khoom.
Nyob rau hauv kev kho cua sov ntawm pas nrig profiles, kuj muaj quenching aging tshav kub kho. Nws yog tsuas yog siv rau kev kho cua sov ntawm cov alloys nrog lub hnub nyoog-zog zog los txhim kho lub zog thiab cov khoom ntawm cov ntaub ntawv. Lub quenching ntawm cov khoom extruded feem ntau yog ua tiav los ntawm kev cia siab rau cov dej foob ntawm lub qhov hluav taws xob extrusion, thaum cov khoom kos yuav tsum muaj lub siab quenching rauv.
ua tiav
Kev ua tiav ntawm tooj liab alloy raj, rods thiab cov xov hlau feem ntau suav nrog lub taub hau thiab tus Tsov tus tw txiav (taw ntev), straightening, deg kho, thiab lwm yam. ntawm cov khoom. High-precision, cov khoom loj loj feem ntau txiav los ntawm sawing. Kev ncaj yog qhov qhia tau zoo rau cov yeeb nkab thiab cov khoom siv bar.
Feem ntau siv cov tshuab straightening rau cov yeeb nkab thiab pas nrig profiles muaj xws li cov menyuam straightening tshuab, siab straightening tshuab, sinusoidal straightening machines thiab nro straightening tshuab, ntawm cov menyuam straightening tshuab yog cov feem ntau siv. Lub tshuab rau cov menyuam straightening ua tiav lub hom phiaj ntawm kev ncaj cov khoom los ntawm kev rov khoov ntawm cov menyuam sib txawv. Siab straighteners feem ntau yog siv rau straightening loj los yog oversized tuav, profiles thiab loj-walled kav. Sine straightening tsuas yog ua tiav lub hom phiaj ntawm txoj kab me me ntawm cov kav dej thiab tuav los ntawm kev rov khoov lawv nrog sine straightening rollers. Lub nro straightening tshuab clamps ob qhov kawg ntawm cov khoom thiab siv rov qab nro los ua micro-deformation ntawm cov khoom kom ua tiav lub hom phiaj ntawm kev ncaj. Nws yog tsuas yog siv rau straightening tshwj xeeb profiles, thiab nws elongation ncav cuag 1-3%.
Txhawm rau kom ntseeg tau tias qhov chaw ntawm cov khoom tiav yog huv si thiab ci, qhov saum npoo ntawm cov khoom yuav tsum tau ua tiav. Muaj ob hom kev tuav tswj thiab kev ua haujlwm tsis siv neeg. Kev siv phau ntawv kev kho mob feem ntau suav nrog cov neeg ua haujlwm tshem tawm cov roj stains thiab av ntawm cov kav dej thiab cov pas nrig (xws li siv cov cua compressed los tshuab paj rwb rau hauv cov kav dej, thiab lwm yam). Kev ua haujlwm tsis siv neeg feem ntau yog hla cov kav dej thiab cov pas nrig los ntawm cov kua ua kua hauv cov tshuaj ntxuav kom huv (xws li purging hauv cov yeeb nkab), ziab thiab lwm yam kev ua haujlwm.
