Nkag siab txog cov txheej txheem vuam rau tungsten Carbide Pom Cov Lus Qhia

    Vuam tungsten carbide (WC) pom cov lus qhia rau kev txiav cov cuab yeej yog cov txheej txheem tseem ceeb hauv kev lag luam hlau nyuaj, txhim khu kev ua haujlwm ntev thiab kev ua haujlwm ntawm cov saw hniav. Tungsten carbide, paub txog nws qhov tshwj xeeb hardness thiab hnav tsis kam, yog siv dav hauv ntau daim ntawv thov txiav. Kab lus no tshawb txog cov txheej txheem vuam, cov kev xav tseem ceeb, thiab cov kev coj ua zoo tshaj plaws rau kev ua tiav cov txiaj ntsig zoo.

Qhov tseem ceeb ntawm vuam

    Vuam tungsten carbide cov lus qhia rau ntawm cov saw hniav ua haujlwm rau ntau lub hom phiaj. Nws tsis tsuas yog txhim kho cov kev ua haujlwm ntawm kev txiav, tab sis kuj tseem txuas ntxiv lub neej ntawm cov hniav. Cov txheej txheem vuam yuav tsum xyuas kom muaj kev sib raug zoo ntawm cov carbide thiab cov khoom siv substrate, feem ntau yog cov hlau kub ceev (HSS) lossis cov cuab yeej hlau, kom tiv taus cov neeg kho tshuab kev ntxhov siab thaum ua haujlwm txiav.

Cov txheej txheem vuam

    Ob peb txoj kev vuam tuaj yeem ua haujlwm rau kev txuas cov lus qhia tungsten carbide, txhua tus muaj nws tus kheej zoo thiab kev txwv. Cov txheej txheem feem ntau muaj xws li:

TIG Vuam (Tungsten Inert Gas):Txoj kev no siv cov tungsten electrode uas tsis yog-consumable tungsten electrode thiab cov roj inert los tiv thaiv thaj tsam weld los ntawm kev sib kis. TIG welding muaj kev tswj xyuas meej ntawm cov cua kub nkag, uas yog qhov tseem ceeb los tiv thaiv kev puas tsuaj rau cov lus qhia carbide. Nws yog tshwj xeeb tshaj yog zoo rau cov ntaub ntawv nyias thiab tso cai rau cov zoo welds.

MIG Vuam (Metal Inert Gas):MIG vuam siv cov hlau txuas txuas ntxiv raws li cov khoom siv hluav taws xob thiab tseem siv cov roj inert rau kev tiv thaiv. Thaum nws yog feem ntau sai dua TIG vuam, nws yuav tsis muab tib theem ntawm precision. Cov txheej txheem no tsim nyog rau kev tsim khoom loj dua qhov twg ceev yog qhov tseem ceeb.

Laser vuam:Txoj kev zoo siab no siv cov kab teeb tsom laser kom yaj cov ntaub ntawv hauv paus thiab tsim kom muaj kev sib raug zoo. Laser vuam paub txog nws qhov tsawg kawg nkaus tshav kub-tshem tawm tsam (HAZ), txo qhov kev pheej hmoo ntawm thermal puas rau tungsten carbide.

Brazing:Txawm hais tias tsis yog txheej txheem vuam hauv qhov kev txiav txim siab nruj tshaj plaws, brazing yuav tsum siv cov hlau muab tub lim los koom nrog cov lus qhia tungsten carbide rau cov hniav. Nws yog ib qho tseem ceeb tshwj xeeb tshaj yog thaum cuam tshuam nrog cov khoom uas muaj cov ntsiab lus melting sib txawv.

Cov ntsiab lus tseem ceeb

Kev npaj ua ntej vuam

    Ua ntej vuam, kev npaj kom zoo yog qhov tseem ceeb. Qhov chaw ntawm ob lub tswv yim tungsten carbide thiab cov substrate yuav tsum huv si thiab tsis muaj kab mob xws li roj, roj, thiab oxidation. Cov txheej txheem xws li abrasive blasting lossis tshuaj ntxuav tuaj yeem ua haujlwm kom ua tiav qhov xav tau ntawm qhov chaw.

Kev Tswj Kub Kub

    Kev tswj cov khoom siv hluav taws xob thaum lub sijhawm vuam yog qhov tseem ceeb kom tsis txhob ua rau cov tungsten carbide puas. Cov cua kub ntau dhau tuaj yeem ua rau muaj qhov tshwm sim hu ua "carbide coarsening," qhov twg cov microstructure ntawm carbide degrades, cuam tshuam rau nws hardness. Kev siv cov txheej txheem xws li pulse welding tuaj yeem pab tswj cov cua sov thiab txo qhov cuam tshuam.

Kev kho tom qab Weld

    Tom qab vuam, nws yuav tsum tau ua tom qab vuam kev kho cua sov kom txo tau cov kev ntxhov siab seem. Qhov kev kho no tuaj yeem txhim kho cov khoom siv ntawm cov welded sib koom ua ke, ua kom muaj kev ruaj khov dua. Cov txheej txheem xws li tempering lossis annealing tuaj yeem ua tau zoo, nyob ntawm cov khoom siv.

Kev Tswj Xyuas Zoo

    Ua raws li kev tswj xyuas kev ntsuas kom zoo thoob plaws hauv cov txheej txheem vuam yog qhov tseem ceeb. Kev kuaj tsis yog kev puas tsuaj (NDT) txoj hauv kev, xws li kev kuaj ultrasonic lossis tshuaj ntsuam xyuas qhov tob, tuaj yeem ua haujlwm los kuaj xyuas qhov tsis xws luag hauv qhov vuam. Xyuas kom ua raws li cov qauv kev lag luam thiab cov kev qhia tshwj xeeb yog qhov tseem ceeb rau kev tswj xyuas kev ncaj ncees ntawm cov khoom tiav.

Xaus

    Vuam tungsten carbide pom cov lus qhia yog txheej txheem nyuaj uas yuav tsum tau ua tib zoo xav txog ntau yam. Los ntawm kev xaiv cov txheej txheem vuam tsim nyog, tswj cov khoom siv hluav taws xob, thiab siv cov kev tswj xyuas kom zoo, cov tuam txhab tsim khoom tuaj yeem tsim cov saw hlau uas ua tau raws li qhov xav tau ntawm cov ntawv txiav niaj hnub. Raws li kev lag luam hlau nyuaj txuas ntxiv mus, kev nce qib hauv vuam tshuab yuav ntxiv dag zog rau cov peev txheej thiab kev siv cov cuab yeej tungsten carbide.
