Cov txheej txheem ntawm Carbide Buttons Manufacturing

Tungsten carbide yog ib qho ntawm cov khoom siv thoob ntiaj teb siv hauv kev lag luam. Lub pob carbide yog tsim los ntawm tungsten carbide, yog li nws muaj cov khoom ntawm cemented carbide. Lub tog raj kheej zoo ntawm tungsten carbide khawm cov khoom ua rau nws yooj yim rau ntxig rau hauv lwm yam cuab yeej los ntawm cua sov inlaying thiab txias nias. Vim tias carbide khawm inserts tuav cov khoom ntawm hardness, toughness, thiab durability, nws yog ib qho uas pom lawv nyob rau hauv ntau yam xwm txheej xws li zoo drilling, pob zeb milling, txoj kev khiav hauj lwm, thiab mining tshwm sim. Tab sis lub pob carbide ua li cas? Hauv kab lus no, peb yuav txheeb xyuas cov lus nug no.

1. Kev npaj cov khoom nyoos

Cov txheej txheem hauv qab no xav tau cov ntaub ntawv WC hmoov thiab Cobalt hmoov. WC hmoov yog ua los ntawm tungsten ores, mined thiab nplua los ntawm xwm. Tungsten ores yuav ntsib ntau yam tshuaj lom neeg, ua ntej nrog oxygen los ua tungsten oxide thiab tom qab ntawd nrog carbon los ua WC hmoov.

2. Cov hmoov sib tov

Tam sim no ntawm no yog thawj kauj ruam yuav ua li cas factories ua carbide hniav. Factories yuav ntxiv qee cov binders (Cobalt hmoov lossis Nickel hmoov) hauv WC hmoov. Binders zoo ib yam li "kua nplaum" hauv peb lub neej niaj hnub los pab ua ke tungsten carbide nruj dua. Cov neeg ua haujlwm yuav tsum sim cov hmoov sib xyaw kom ntseeg tau tias nws tuaj yeem siv tau hauv cov kauj ruam hauv qab no.

3. Ntub Milling

Thaum lub sij hawm cov txheej txheem no, cov hmoov sib tov yuav muab tso rau hauv lub Pob Zeb Milling Tshuab thiab milled nrog kua zoo li dej thiab ethanol. Cov kua no yuav tsis hnov mob chemical tab sis pab kev sib tsoo.

4. Txau kom qhuav

Cov txheej txheem no ib txwm tshwm sim hauv lub tshuab ziab khaub ncaws. Tab sis cov chaw tsim khoom sib txawv tuaj yeem xaiv ntau hom tshuab. Ob hom tshuab hauv qab no muaj ntau. Ib qho yog Lub Tshuab Nqus Tsev; lwm qhov yog Spray Drying Tower. Lawv muaj lawv qhov zoo. Txau kom qhuav ua haujlwm nrog cov cua kub siab thiab cov pa roj inert kom evaporate cov dej. Nws tuaj yeem evaporate feem ntau ntawm cov dej, uas ua tau zoo dua rau ob txoj haujlwm hauv qab no Nias thiab Sintering. Lub tshuab nqus tsev ziab tsis xav tau qhov kub thiab txias tab sis yog kim thiab raug nqi ntau los tswj.

5. Nias

Txhawm rau nias hmoov rau hauv cov duab sib txawv uas cov neeg siv khoom xav tau, cov neeg ua haujlwm yuav ua pwm ua ntej. Carbide nyees khawm tuaj nyob rau hauv cov duab sib txawv yog li koj tuaj yeem pom ntau hom kev tuag, nrog lub taub hau conical, lub taub hau pob, lub taub hau parabolic, lossis rab diav taub hau, nrog ib lossis ob lub chamfers, thiab nrog lossis tsis muaj pinholes. Muaj ob txoj kev shaping. Rau qhov me me ntawm cov nyees khawm, cov neeg ua haujlwm yuav nias los ntawm lub tshuab tsis siv neeg; rau qhov loj dua, cov neeg ua haujlwm yuav nias los ntawm lub tshuab hydraulic pressing.

6. Sintering

Cov neeg ua haujlwm yuav muab cov lus qhia me ntsis carbide rau ntawm lub phaj graphite thiab hauv Kub Isostatic Pressing (HIP) Sintered Rauv nyob rau hauv qhov kub ntawm txog 1400˚ C. Qhov kub yuav tsum tau tsa ntawm qhov qis qis kom lub carbide khawm shrinks qeeb thiab ua tiav. khawm muaj kev ua tau zoo dua. Tom qab sintering, nws yuav ntsws thiab tsuas muaj ze li ib nrab ntawm ntau npaum li ua ntej.

7. Kev kuaj xyuas zoo

Kev kuaj xyuas zoo yog qhov tseem ceeb heev. Carbide inserts yog thawj zaug kuaj xyuas cov khoom xws li hardness, cobalt magnetic, thiab microstructure los xyuas cov qhov lossis cov kab nrib pleb me me. Lub micrometer yuav tsum tau siv los xyuas nws qhov loj, qhov siab, thiab txoj kab uas hla ua ntej ntim.
