Cemented carbide muab faib ua tungsten-cobalt, tungsten-titanium, tungsten-titanium-tantalum-cobalt. tungsten, cobalt, thiab titanium yog cov tawv tawv tawv.
1. Tungsten-cobalt carbide txiav cov cuab yeej muaj xws li YG6, YG8, YG8N, thiab lwm yam. Cov cuab yeej txiav carbide no yog tsim rau kev ua cov hlau tsis-ferrous, stainless hlau, cam khwb cia hlau, thiab lwm yam ntaub ntawv;
2. Tungsten thiab titanium carbide tej cuab yeej muaj xws li YT5, YT15, thiab lwm yam. Hom carbide-txiav cuab yeej no yog tsim rau kev ua cov ntaub ntawv tawv xws li hlau;
3. Tungsten-titanium-tantalum-cobalt carbide tej cuab yeej muaj xws li: YW1, YW2, YS25, WS30, thiab lwm yam. Hom carbide-txiav cov cuab yeej no yog tsim rau kev ua cov khoom nyuaj-rau-tshuab xws li cov hlau kub-resistant, siab manganese. steel, stainless hlau, thiab lwm yam.
Kev ua tau zoo ntawm cemented carbide
1. High hardness (86 ~ 93HRA, sib npaug rau 69 ~ 81HRC);
2. Zoo thermal hardness (tuaj yeem ncav cuag 900 ~ 1000 ℃, tswj 60HRC);
3. Zoo hnav tsis kam.
Carbide-txiav cov cuab yeej muaj qhov txiav ceev ntawm 4 mus rau 7 npaug siab dua cov hlau ceev thiab lub cuab yeej lub neej yog 5 txog 80 npaug ntev dua. Rau kev tsim pwm thiab ntsuas cov cuab yeej, lub neej kev pab cuam yog 20 mus rau 150 lub sij hawm ntev dua li cov cuab yeej hlau alloy. Nws tuaj yeem txiav cov ntaub ntawv nyuaj nrog ib puag ncig 50HRC. Txawm li cas los xij, cemented carbide yog nkig heev thiab tsis tuaj yeem ua tiav. Nws yog ib qho nyuaj rau ua ib tug complex-puab ib tug cuab tam. Yog li ntawd, cov hniav ntawm cov duab sib txawv feem ntau yog tsim thiab ntsia rau ntawm lub cuab yeej lossis pwm lub cev siv vuam, kev sib txuas, tshuab clamping, thiab lwm yam.
Kev faib tawm ntawm cemented carbide
1. Tungsten-cobalt carbide
Cov khoom tseem ceeb yog tungsten carbide (WC) thiab binder cobalt (Co). Nws lub npe yog tsim los ntawm "YG" (thawj Suav pinyin ntawm "nyuaj, cobalt") thiab feem pua ntawm cov ntsiab lus cobalt nruab nrab. Piv txwv li, YG8 txhais tau hais tias qhov nruab nrab WCo = 8% thiab tus so yog tungsten carbide tungsten cobalt carbide. Feem ntau, tungsten-cobalt alloys feem ntau yog siv hauv cov cuab yeej carbide-txiav, pwm, thiab cov khoom lag luam geological thiab ntxhia.
2. Tungsten titanium cobalt carbide
Cov khoom tseem ceeb yog tungsten carbide, titanium carbide (TiC), thiab cobalt. Nws lub npe muaj "YT" (lub npe ntawm Suav pinyin ntawm "nyuaj thiab titanium") thiab cov ntsiab lus nruab nrab ntawm titanium carbide. Piv txwv li, YT15 txhais tau tias nruab nrab TiC = 15%, thiab tus so yog tungsten titanium cobalt cemented carbide nrog tungsten carbide thiab cobalt cov ntsiab lus.
3. Tungsten titanium tantalum (niobium) carbide
Cov khoom tseem ceeb yog tungsten carbide, titanium carbide, tantalum carbide (los yog niobium carbide), thiab cobalt. Hom cemented carbide no tseem hu ua universal cemented carbide lossis universal cemented carbide. Nws lub npe muaj xws li "YW" (tus suav pinyin ua ntej ntawm "nyuaj" thiab "wan") ntxiv rau tus lej, xws li YW1.
