Yuav Ua Li Cas Cov Lus Qhia Carbide

I. Kev tswj cov khoom siv raw thiab cov khoom pabcuam.

1. Cov khoom siv raw ntawm tungsten carbide hmoov thiab cobalt hmoov yuav raug kuaj ua ntej siv los ua cov cuab yeej tungsten carbide. Peb yuav siv metallographic tsom xam, nws tau txiav txim siab hais tias qhov luaj li cas ntawm WC fluctuates nyob rau hauv ib tug tej yam ntau yam, thiab nyob rau tib lub sij hawm, kab kawm thiab tag nrho cov carbon yog nruj me ntsis tswj.

2. Lub pob milling xeem yog ua rau txhua pawg ntawm WC yuav, thiab cov ntaub ntawv yooj yim xws li hardness, dabtsi yog khoov zog, cobalt hlau nplaum, coercive force, thiab ntom yog soj ntsuam kom nkag siab tag nrho nws lub cev.

II. Manufacturing txheej txheem tswj.

1. Pob milling thiab sib tov, uas yog cov txheej txheem ntawm granulation, uas txiav txim siab qhov xoob ratio thiab fluidity ntawm qhov sib tov. Peb lub tuam txhab txais cov cuab yeej siv tshuaj tsuag granulation tshiab kawg los daws qhov fluidity ntawm qhov sib tov.

2. Nias, uas yog cov txheej txheem ntawm cov khoom tsim, peb txais yuav ib tug tsis siv neeg xovxwm los yog TPA xovxwm los tsim, Yog li txo cov kev cuam tshuam ntawm tib neeg yam ntawm lub pressing embryo.

3. Sintering, Peb lub tuam txhab txais kev siv tshuab sintering uas tsis tshua muaj siab los xyuas kom muaj ib qho chaw nyob hauv lub cub tawg, thiab tsis siv neeg tswj cov cua sov, cua sov, cua txias, thiab cov pa roj carbon sib npaug hauv cov txheej txheem sintering.

III. Cov khoom kuaj.

1. Ua ntej, peb yuav siv sandblasting lossis passivation ntawm cemented carbide cov lus qhia kom nthuav tawm cov khoom puas.

2. Tom qab ntawd, peb yuav ua tiav cov kev ntsuam xyuas metallographic ntawm cov pob txha tawg ntawm cov khoom, Yog li txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm

3. Tag nrho cov kev ntsuam xyuas thiab kev soj ntsuam ntawm lub cev thiab kev tsis sib xws, nrog rau cov hardness, lub zog, cobalt hlau nplaum, lub zog sib nqus, thiab lwm yam kev ntsuas, thaum kawg ua tau raws li qhov yuav tsum tau ua raws li qib.

4. Tom qab tag nrho cov kev ntsuam xyuas, peb yuav ua raws li qhov kev ntsuam xyuas vuam ntawm cov khoom kom ntseeg tau tias kev ruaj ntseg ntawm vuam kev ua tau zoo.

Qhov no yog cov txheej txheem ntawm kev tsim cov lus qhia me me carbide, Nws nyuaj tab sis tsim nyog.
