Rau kev tso cai carbide composite cov khoom lag luam, vuam yog ib qho yooj yim siv cov kev ua haujlwm vuam, thiab ua rau cov khoom lag luam zoo ib txwm, thiab txhua txoj kev ua tiav yuav poob qis. Yog li ntawd, nws yog ib qho tseem ceeb heev kom nkag siab txog qhov ua rau tawg nyob rau hauv cemented carbide vuam thiab kom tsis txhob vuam lawb tawm. Niaj hnub no, tus kws kho mob ntawm Chuangrui Technology yuav tham nrog koj txog cov laj thawj ntawm cov kab nruam hauv carbide vuam, thiab muab qee yam siv.
Hauv vuam, cov khoom sib txawv yuav muaj cov yam ntxwv sib txawv. Tsuas yog paub txog hom ntaub ntawv los ua welded peb tuaj yeem tsim lub vuam npaj, yog li kom xaiv cov txheej txheem tsim nyog kom ntseeg tau qhov zoo vuam. Cov laj thawj rau cov kab nrib pleb hauv cemented carbide vuam yog feem ntau txheeb xyuas los ntawm cov hauv qab no yam.
Ua ntej, nws yog txiav txim siab los ntawm cov yam ntxwv ntawm cov cemented carbide Cai Laoda. Raws li peb txhua tus paub, lub hardness ntawm lub vuam puag hlau hlau nyob ntawm cov carbon basts nyob rau hauv cov khoom. Nrog rau kev nce ntawm cov ntsiab lus carbon, lub hardness yuav nce raws li, thiab tau ntawm cov kev nyiam ntawm cov nrib pleb yuav nce ntxiv. Yog li ntawd, cemented carbide vuam yog nquag rau tawg.
Qhov thib ob, thaum twg cemented carbide yog welded, piv rau cov khoom siv hluav taws xob qis, thiab kev sib ntaus sib tua hluav taws xob kom loj hlob tuaj yeem tshwm sim. Nyob rau hauv lub vuam tshav kub, lub microstructure thiab cov khoom ntawm cov cua sov tuaj cheeb tsam ntawm weld hloov, yog li nce txoj kev nyiam ntawm tiam nrad.
Thib peb, lub embrittlement ntawm cov qauv overheated nyob rau hauv cov cua sov tuaj cheeb tsam ntawm welded sib koom tes ua rau qhov tshwm sim ntawm vuam sib tsoo. Qhov no feem ntau yog nyob ntawm cov cemented carbide ntoo muaj pes tsawg leeg, uas yuav cuam tshuam los ntawm tus nqi kub thiab txias ntawm lub pas dej molten.
Qhov saum toj no yog ntau cov laj thawj yog vim li cas cemented carbide vuam yuav ua rau tawg. Rau kev siv vuam ntawm cov ntaub ntawv xws li, nws yog qhov tsim nyog los ua ke cov yam ntxwv vuam ntawm cov ntaub ntawv los kho cov txheej txheem vuam, npaj ua ntej cov txheej txheem, thiab ntxiv dag zog rau cov txheej txheem vuam. Preheating, post-weld kev kho kom sov thiab kev kho cua sov yog qhov tsim nyog los tiv thaiv kev ua kom cov paemented carbide vuam.
Cemented carbide yog qhov nyuaj heev thiab nkig. Ib qho kev tsis quav ntsej me ntsis hauv cov txheej txheem vuam yuav ua rau txhawm rau txhawm rau txhawm rau tawg. Yog li ntawd, peb yuav tsum npaj npaj siab thaum vuam cemented carbide. Cov qauv txheej txheem kom tsis txhob muaj vuam tawg.
