Ntau tus Exchamen yuav tsis muaj kev nkag siab tshwj xeeb ntawm kev tso cai carbide. Raws li cov kev ua haujlwm ntawm kev ua haujlwm carbide
Tungsten carbide muaj lub koob npe nrov ntawm "cov hniav kev lag luam", thiab nws cov ntawv thov loj heev, tshuab, cov nkoj, tub rog thiab lwm thaj chaw. Lub tungsten noj nyob rau hauv cov cemented carbide kev lag luam tshaj ib nrab ntawm tag nrho cov tungsten noj. Peb yuav qhia nws los ntawm nws cov lus txhais, cov yam ntxwv, kev faib tawm thiab siv.
1. Txhais
Cemented carbide yog ib qho alloy nrog tungsten carbide hmoov (WC) raws li cov khoom siv ntau lawm thiab cobalt, molybdenum thiab lwm yam hlau raws li lub phau ntawv. Tungsten alloy yog ib qho alloy nrog tungsten li theem nyuaj thiab hlau cov ntsiab lus xws li npib tsib, thiab tooj ua cov ntu.
2. NTA
1) hardness siab (86 ~ 93 hli, sib npaug ntawm 69 ~ 81hrc). Nyob rau lwm cov xwm txheej, ntau dua cov ntsiab lus ntawm tungsten carbide thiab cov nplej zom, qhov nyuaj ntawm cov alloy.
2) hnav kev tiv thaiv zoo. Lub cuab yeej lub neej tsim los ntawm cov khoom no yog 5 txog 80 npaug siab dua li cov kev txiav ceev ceev ntawm kev ceev; Lub neej ntawm cov cuab yeej abrasive tsim los ntawm cov khoom siv no yog 20 txog 150 npaug siab dua li cov cuab yeej cov hlau uas muaj cov khoom siv Abrasive.
3) Kev tiv thaiv tshav kub zoo heev. Nws cov hardness tseem tsis tau hloov pauv ntawm 500 ° C, thiab lub hardness tseem muaj siab heev ntawm 1000 ° C.
4) muaj zog tiv thaiv corrosion. Nyob rau hauv ib txwm muaj xwm txheej, nws tsis hnov mob nrog hydrochloric acid thiab sulfuric acid.
5) Zoo heev. Nws txoj kev nruj yog txiav txim los ntawm cov binder hlau, thiab ntau dua cov kev sib tw cov ntsiab lus, qhov ntau dua lub zog flexural.
6) Great brittleness. Nws yog qhov nyuaj rau ua cov cuab yeej nrog cov duab nyuaj vim tias kev txiav tsis tau.
3. Kev Sib Tw
Raws li cov kev sib txawv, cemented carbide tuaj yeem faib ua cov hauv qab no:
1) tungsten-cobalt alloys yog tungsten carbide thiab cobalt, uas tuaj yeem siv los ua cov cuab yeej txiav, pwm thiab geological thiab geological thiab geological thiab cov ntxhia cov khoom lag luam.
2) tungsten-tungsten-cobalt alloys: lub Cheebtsam tseem ceeb yog tungsten carbide, titanium carbide thiab cobalt.
3) tungsten-tungysten-tantalum (niobium) alloys yog tungsten carbide, tantalum carbide (lossis nobalt.
Raws li cov qauv sib txawv, lub hauv paus tuaj yeem faib ua peb hom: kheej, pas nrig thiab phaj. Cov duab ntawm cov khoom tsis yog cov qauv khoom yog qhov tshwj xeeb thiab yuav tsum tau kho kom haum. Zhuzhou Chuzegrui cemented carbide muab kev tshaj lij kev siv cov kev qhia.
4. Kev npaj
1) Cov khoom xyaw: Cov khoom siv raw tau sib xyaw ua feem sib xyaw; 2) Ntxiv cawv lossis lwm yam xov xwm, ntub kev sib tsoo hauv cov pob ntub; 3) Tom qab crushing, ziab, thiab sixing, ntxiv ciab lossis kua nplaum thiab lwm cov neeg sawv cev; 4) GRANULULULULULULINE qhov sib tov, nias thiab cua sov kom tau txais cov khoom lag luam.
5. Siv
Nws tuaj yeem siv los ua kom laum khoom, riam, cov cuab yeej drilling pob zeb, hnav, lub tog raj kheej, lub cev muaj zog rotors thiab cov ntsiab lus, thiab lwm yam.
