Kev Taw Qhia Txog Hardfacing thiab Nws Cov Khoom Siv Carbide

Nyob rau hauv xyoo tas los, hardfacing tau dhau los ua qhov teeb meem ntawm kev loj hlob hnyav uas cuam tshuam rau kev hnav resistant daim ntaub ntawv. Hardfacing, tseem hu ua "Hardsurfacing", yog daim ntawv thov ntawm cov khoom siv los yog hnav-resistant weld hlau rau ib feem ntawm qhov chaw los ntawm kev siv vuam los yog koom ua ke los tiv thaiv kev puas tsuaj, corrosion, kub kub, lossis cuam tshuam. Nws yog deposition ntawm tuab coatings ntawm ib tug tawv, hnav-resistant cov ntaub ntawv ntawm ib tug hnav los yog tshiab tivthaiv nto uas yuav tsum tau hnav nyob rau hauv kev pab cuam. Thermal spraying, spray-fuse thiab vuam txheej txheem feem ntau yog siv los siv cov txheej txheem hardfacing. Xws li cov hlau yuav muab tso rau ntawm qhov chaw, ib qho ntug, lossis tsuas yog qhov taw tes ntawm ib feem uas yuav tsum hnav. Vuam deposits tuaj yeem ua haujlwm rau qhov chaw thiab rov qab cov khoom txuas ntxiv lawv lub neej kev pabcuam. Vuam yog ib qho tseem ceeb thev naus laus zis los ua kom tiav cov kev xav tau no thiab siv hardfacing alloys. Cov khoom tseem ceeb xws li crushers raug rau hnyav hnyav thiab yuav tsum tau muaj kev tiv thaiv saum npoo kom tsis txhob raug nqi qis thiab txo tus nqi rau cov khoom seem kim. Cov txheej txheem no tau txais kev pom zoo thoob plaws ntau qhov kev lag luam xws li Cement, Mining, Steel, Petro-chemical, Fais Fab, Qab Zib thiab Khoom Noj.

Tungsten carbide yog ib qho ntawm cov ntaub ntawv nyuaj tshaj plaws rau kev siv hauv kev lag luam. Nws tsis tuaj yeem yaj los ntawm cov nplaim hluav taws kub tsawg. Nws kuj yog nkig heev. Rau lub hom phiaj nyuaj, nws yog crushed thiab siv ua ke nrog ib tug "binding" hlau. Cov tungsten carbide hais feem ntau yog nyob rau hauv ib tug steel raj pas nrig.

ZZBETTER muaj ntau yam xws li hardfacing vuam cov ntaub ntawv raws li nram no:

1.Tungsten Carbide Hnav Inserts:

2.Tungsten Carbide Grits: Tungsten carbide grit muab kev tiv thaiv kev hnav ntev ntev hauv thaj chaw ntawm kev hnav siab. Nws yog siv los tiv thaiv cov khoom kim heev xws li cov khoom siv bulldozer, thoob cov hniav, sib tsoo ntoo, rauj, cov hniav trencher, thiab ntau yam ntawm lwm yam khoom siv. Tungsten Carbide grit yog ib qho txiaj ntsig zoo ntawm kev tiv thaiv cov tshuab thiab cov khoom siv los ntawm kev muab qhov tseem ceeb hauv kev ua haujlwm ntev ntawm cov khoom. Qhov no txo ​​qis downtime thiab txo tus nqi cuam tshuam nrog qhov tsis muaj kev tiv thaiv.

3.Composite Rods nrog Carbide Inserts: Cov kev ua tau zoo ntawm cov pas nrig siv peb cov carbide inserts muab rau koj nrog kev nruj nruj txiav cov npoo thiab cov robustness yuav tsum tau nyob rau hauv qhov tseem ceeb ntawm koj cov cuab yeej milling.

4.Nickel Carbide Composite qws: Nickel carbide composite rods tau ua lub hardfacing thiab kho cov khoom siv ruaj khov thiab siv los ua kev tiv thaiv rau cov stabilizers thiab reamers hauv kev lag luam roj thiab roj. Qhov loj tungsten carbide pellets muab kev tiv thaiv kev puas tsuaj thaum cov pellets zoo dua tiv thaiv cov matrix ntawm hnav thiab yaig. Cov npib tsib xee matrix muab qhov kub thiab txias tiv thaiv corrosion, tiv thaiv lub cev me ntsis thiab tso cai rau kev kho dua tshiab thiab laum lub taub hau rov siv dua.

5.Flexible Vuam hlua: Flexible vuam hlua yog tsim los ntawm cam khwb cia tungsten carbide, kheej kheej cam khwb cia tungsten carbide los yog ib tug sib tov ntawm ob raws li ib tug nyuaj theem, nws tus kheej-fluxing npib tsib xee alloy hmoov rau lub tsev cog khoom theem, raws li ib tug tej yam kev faib ua feem ntawm mixed bonding, extrusion molding, ziab, thiab tom qab ntawd tsim los ntawm nickel hlau.

6.Nickel Silver Tinning Rods: Nickel silver tinning rods yog cov hom phiaj oxyacetylene rods rau braze vuam ntau yam ferrous thiab non-ferrous hlau, xws li hlau, cam khwb cia hlau, malleable hlau, thiab ib co nickel alloys. Lawv feem ntau yog siv rau fusion vuam ntawm tooj dag, bronze, thiab tooj liab alloys nrog rau kev tsim cov chaw hnav.

7.Cam khwb cia tungsten Carbide hmoov: Cam khwb cia tungsten carbide hmoov, feem ntau hu ua W2C, yog ib qho khoom siv tawv heev uas siv ntau yam kev siv. Nrog cov qauv eutectic, siab melting point thiab hardness, uas tuaj yeem pab tiv thaiv hnav thiab hnav tsis kam. Cov khoom siv yog tsimlos ntawm kev sib xyaw ntawm cov pa roj carbon, tungsten thiab tungsten carbide hmoov thiab yog nyiaj / grey nyob rau hauv cov xim nrog ib tug ntse blocky particle zoo.

8.Tungsten Carbide Pellet Vuam Rods: Piv nrog cam khwb cia tungsten carbide hmoov, tungsten carbide pellets muaj kev cuam tshuam zoo dua thiab hnav tsis kam. Nws muaj cov yam ntxwv ntawm ib zaug welding yam tsis muaj reflow soldering. Cov pellets yog spherical; Qhov kev sib txhuam coefficient yog me me, uas tuaj yeem txo qhov hnav thiab ua haujlwm zoo.

Q: Puas yog hardfacing tsim nyog? 

Hardfacing tuaj yeem ua tiav los ntawm kev siv ntau yam txheej txheem, ob qho tib si hauv khw thiab hauv thaj chaw, ua kom muaj ntau yam thiab siv tau zoo. Tsis tas li ntawd, kev siv cov txheej txheem no ntawm cov khoom tshiab tuaj yeem txuas lub neej kev pab txog li 300%. Txawm li cas los xij, yog tias koj hardface hnav cov khoom, koj tuaj yeem txuag tau txog 75% piv rau cov nqi hloov.

Los xaus, hardfacing yog cov txheej txheem ntau yam los txhim kho lub neej ntawm cov khoom siv hnav; hardfacing yog qhov zoo tshaj plaws xaiv txheej txheem hnub no kom txo tau tus nqi hloov; hardfacing txo lub sijhawm poob vim tias qhov chaw nyob ntev dua thiab tsawg dua qhov kev kaw yuav tsum tau hloov pauv; hardfacing tuaj yeem ua tiav ntawm cov khoom siv hlau siv ntau yam txheej txheem vuam.

Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv no.
