Tungsten carbide sawb feem ntau yog ua los ntawm WC tungsten carbide thiab Co cobalt hmoov tov los ntawm metallurgical txoj kev los ntawm pulverization, pob milling, nias thiab sintering, lub ntsiab alloy Cheebtsam yog WC thiab Co, cov ntsiab lus ntawm WC thiab Co nyob rau hauv sib txawv siv tungsten carbide sawb. tsis zoo ib yam, thiab kev siv ntau yam yog dav heev.
Ib qho ntawm cov khoom siv feem ntau ntawm tungsten carbide strips, nws muaj npe vim nws cov duab plaub ntawm daim hlau (los yog squares), tseem hu ua tungsten carbide sawb / daim hlau. Tungsten carbide sawb muaj cov tawv tawv zoo heev, zoo hnav tsis kam, siab elastic modulus, siab compressive zog, zoo tshuaj stability (acid, alkali, kub oxidation kuj), tsis tshua muaj tej yam toughness, tsawg expansion coefficient, thermal thiab hluav taws xob conductivity zoo li hlau thiab nws. alloys.
Dab tsi yog vim li cas rau covkev tsis ncaj nceesPuas yog tungsten carbide strips? Chuangrui carbide yuav teb tom ntej:
(1) Lub brazing nto ntawm tungsten carbide tsis sanded los yog polished ua ntej welding, thiab oxide txheej ntawm lub brazing nto yuav txo tau cov wetting nyhuv ntawm cov hlau brazing thiab tsis muaj zog lub zog ntawm lub vuam.
(2)DesolderingNws tseem yuav tshwm sim thaum tus neeg sawv cev brazing tsis raug xaiv thiab siv tsis raug, piv txwv li, thaum borax siv los ua tus neeg sawv cev brazing, borax tsis tuaj yeem ua lub luag haujlwm deoxidizing zoo vim tias borax muaj cov dej noo ntau dua, thiab cov khoom siv brazing tsis tuaj yeem ua kom zoo wetted. nyob rau saum npoo brazed, thiab covkev tsis ncaj nceesphenomenon tshwm sim.
(3) Qhov kub ntawm lub brazing yuav tsum yog 30 ~ 50 ° C siab tshaj qhov melting point ntawm cov hlau brazing, thiabkev tsis ncaj nceesyuav tshwm sim yog tias qhov kub thiab txias dhau los yog qis dhau. Cov cua kub ntau dhau tuaj yeem ua rau oxidation hauv cov vuam. Kev siv cov zinc uas muaj cov hlau brazing yuav muab cov xim xiav lossis xim dawb. Thaum lub brazing kub tsawg dhau lawm, ib tug kuj tuab weld yuav tsim, thiab sab hauv ntawm weld yuav tsum tau them nrog porosity thiab slag inclusions. Ob qho xwm txheej saum toj no yuav txo lub zog ntawm vuam, thiab nws yooj yim rau deweld thaum sharpened los yog siv.
(4) Nyob rau hauv cov txheej txheem brazing, tsis muaj slag tawm raws sij hawm los yog tsis txaus slag paug, yog li ntawd ib tug loj npaum li cas ntawm brazing tus neeg sawv cev slag tseem nyob rau hauv lub weld, uas yuav txo tau lub zog ntawm weld thiab ua rau.kev tsis ncaj ncees.
