Rau cov cemented carbide composite cov khoom, vuam yog ib qho kev siv cov txheej txheem ua, tab sis feem ntau me ntsis careless, nws yog ib qho yooj yim los tsim vuam kab nrib pleb, ua rau cov khoom yuav tsum scrapped, thiab tag nrho cov yav dhau los ua yuav luv luv.Yog li ntawd, nws yog ib qho tseem ceeb heev kom nkag siab txog qhov ua rau ntawm cov kab nrib pleb hauv cemented carbide welding thiab kom tsis txhob vuam tawg.Niaj hnub no, tus editor ntawm Chuangrui Technology yuav tham nrog koj txog cov laj thawj ntawm cov kab nrib pleb hauv carbide welding, thiab muab qee qhov kev siv rau koj.
Hauv vuam, cov khoom sib txawv yuav muaj cov yam ntxwv sib txawv.Tsuas yog los ntawm kev paub txog cov khoom siv uas yuav tsum tau welded tuaj yeem tsim kho qhov kev tsim kho vuam kom raug, thiaj li xaiv cov txheej txheem kom raug los xyuas kom cov vuam zoo.Cov laj thawj ntawm cov kab nrib pleb hauv cemented carbide welding feem ntau yog txheeb xyuas los ntawm cov hauv qab no.
Ua ntej, nws yog txiav txim los ntawm cov yam ntxwv ntawm cov cemented carbide Cai Laoda.Raws li peb txhua tus paub, lub hardness ntawm vuam puag hlau yog nyob ntawm cov khoom siv carbon.Nrog rau qhov nce ntawm cov ntsiab lus carbon, lub hardness yuav nce raws li, thiab ntawm chav kawm qhov nyiam ntawm cov kab nrib pleb generated thaum vuam yuav nce.Yog li ntawd, cemented carbide welding yog feem ntau ua rau tawg.
Thib ob, thaum cemented carbide yog welded, piv nrog cov hlau tsis tshua muaj hlau, nws qhov vuam kub cuam tshuam cheeb tsam yog qhov yooj yim rau cov qauv tawv, uas yog rhiab heev rau cov khoom siv hydrogen hauv vuam, thiab cov welded sib koom ua ke ntawm cemented carbide tuaj yeem tiv taus ntau dua hauv kev ntxhov siab, ntau yam. Cov kab nrib pleb yuav tshwm sim.Nyob rau hauv lub welding cua sov voj voog, lub microstructure thiab cov khoom ntawm lub tshav kub cuam tshuam cheeb tsam ntawm weld hloov, yog li ua rau cov nyiam ntawm tawg tiam.
Thib peb, lub embrittlement ntawm lub overheated qauv nyob rau hauv lub tshav kub cuam tshuam cheeb tsam ntawm lub welded ob leeg ua rau qhov tshwm sim ntawm vuam tawg.Qhov no feem ntau yog nyob ntawm cov cemented carbide ntoo muaj pes tsawg leeg thiab lub voj voog vuam kub, uas yuav cuam tshuam los ntawm qhov kub thiab txias lub sij hawm nyob thiab txias npaum li cas ntawm lub pas dej molten thaum vuam.
Cov saum toj no yog ob peb lub laj thawj vim li cas cemented carbide vuam yuav ua rau tawg.Rau kev vuam ntawm cov ntaub ntawv zoo li no, nws yog ib qho tsim nyog los ua ke cov yam ntxwv ntawm cov khoom siv vuam kom raug xaiv cov khoom siv vuam, ua kev npaj ua ntej thiab tom qab vuam, ua raws li cov txheej txheem nruj me ntsis, thiab ntxiv dag zog rau cov txheej txheem vuam.Preheating, tom qab-weld preservation thiab kev kho cua sov yog tsim nyog los tiv thaiv qhov tshwm sim ntawm cemented carbide vuam tawg.
Cemented carbide yog qhov nyuaj heev thiab nkig.Ib qho kev tsis saib xyuas me ntsis hauv cov txheej txheem vuam yuav ua rau scrapping vim tawg.Yog li ntawd, peb yuav tsum ua kom tiav kev npaj thaum vuam cemented carbide.Cov txheej txheem txheej txheem kom tsis txhob vuam tawg.
