Wet Milling Effects rau Cemented Carbide Mixtures

Lub hom phiaj ntawm kev ntub dej milling yog txhawm rau zeb cov tungsten carbide hmoov rau qhov xav tau qhov loj me, kom ua tiav kev sib xyaw kom txaus thiab sib xyaw nrog cobalt hmoov nyob rau hauv ib qho kev faib ua feem, thiab kom muaj kev nias zoo thiab sintering zog. Cov txheej txheem ntub dej no feem ntau siv cov tungsten carbide pob thiab cawv dov txoj kev.

Dab tsi yog qhov ntub milling cuam tshuam rau tungsten carbide sib tov?

1. Sib tov

Muaj ntau yam khoom sib xyaw ua ke, thiab qhov ntom thiab particle loj ntawm txhua yam kuj txawv. Txhawm rau kom tau txais cov khoom lag luam zoo cemented carbide, ntub milling tuaj yeem xyuas kom meej tias cov khoom sib xyaw yuav tsum sib npaug.

2. Sib tsoo

Cov ntsiab lus me me ntawm cov khoom siv raw siv hauv kev sib tov sib txawv, tshwj xeeb tshaj yog WC uas muaj cov qauv agglomerate. Tsis tas li ntawd, vim qhov kev xav tau tiag tiag ntawm kev ua haujlwm thiab kev tsim khoom, WC ntawm cov qib sib txawv thiab qhov ntau thiab tsawg feem ntau yog sib xyaw. Ob qho no ua rau muaj qhov sib txawv loj hauv qhov loj me ntawm cov khoom siv raw, uas tsis tsim nyog rau kev tsim cov hlau zoo. Kev sib tsoo ntub dej tuaj yeem ua lub luag haujlwm ntawm cov khoom crushing thiab particle loj homogenization.

3. Kev ua pa

Kev sib tsoo thiab kev sib txhuam ntawm cov khoom sib tov, cov milling cov menyuam, thiab cov pob zeb milling yog ntau dua rau oxidation. Tsis tas li ntawd, cov dej hauv milling nruab nrab cawv kuj ua rau cov nyhuv oxygenation. Muaj ob txoj hauv kev los tiv thaiv oxygenation: ib qho yog cua txias, feem ntau yog los ntawm kev ntxiv lub tsho dej txias sab nraum lub thoob ntawm lub pob zeb kom tswj tau qhov kub thiab txias thaum lub sijhawm ua haujlwm ntawm lub pob zeb; lwm qhov yog xaiv cov txheej txheem tsim khoom tsim nyog, xws li cov organic ua liaj ua teb tus neeg sawv cev thiab cov ntaub ntawv raw pob zeb ua ke vim tias cov organic forming agents tsim cov yeeb yaj kiab tiv thaiv ntawm cov khoom siv raw, uas muaj cov nyhuv ntawm kev sib cais oxygen.

4. Kev ua haujlwm

Nyob rau hauv cov txheej txheem ntawm pob zeb milling, vim yog kev sib tsoo thiab kev sib txhuam, cov iav siv lead ua ntawm cov hmoov yog yooj yim distorted thiab distorted, thiab lub zog sab hauv nce. Qhov kev ua kom no muaj txiaj ntsig zoo rau sintering shrinkage thiab densification, tab sis nws kuj yog ib qho yooj yim los ua "tawg", ces kev loj hlob tsis sib xws thaum sintering.

Yuav kom txo tau qhov ua kom cov nyhuv, cov ntub milling yuav tsum tsis txhob ntev dhau. Thiab xaiv lub sijhawm ntub dej milling tsim nyog raws li qhov loj me ntawm qhov sib tov.

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.
