Cemented carbide muaj cov khoom zoo heev xws li siab hardness, hnav tsis kam, zoo zog thiab toughness, kub tsis kam, thiab corrosion kuj. Tshwj xeeb, nws cov hardness siab thiab hnav kuj tseem tsis hloov txawm nyob rau ntawm qhov kub ntawm 500 ° C. , tseem muaj siab hardness ntawm 1000 ° C. Muaj peb yam tseem ceeb ntawm carbide rau cov cuab yeej txiav, carbide rau geological mining cov cuab yeej thiab carbide rau hnav-resistant qhov chaw.

1. Carbide rau cov cuab yeej txiav: Carbide rau cov cuab yeej txiav tau muab faib ua rau 6 pawg: P, M, K, N, S, thiab H raws li kev siv ntau yam;

P-hom: Alloy / txheej alloy raws li TiC thiab WC, nrog Co (Ni + Mo, Ni + Co) ua tus khi. Nws feem ntau yog siv los ua cov ntaub ntawv ntev ntev, xws li steel, cam khwb cia hlau, thiab ntev-txiav malleable cam khwb cia hlau. Kev ua haujlwm; coj qib P10 ua piv txwv, cov txheej txheem siv tau yog tig, luam tawm, threading, thiab milling nyob rau hauv kev txiav ceev, nruab nrab thiab me me hla ntu ntu;

Class M: Alloy / txheej alloy raws li WC, nrog Co raws li binder, thiab ib qho me me ntawm TiC ntxiv. Nws yog feem ntau siv hauv kev ua cov hlau tsis muaj steel, cam khwb cia hlau, manganese steel, malleable cam khwb cia hlau, hlau alloy, alloy cam khwb cia hlau, thiab lwm yam .; Qib M01 Piv txwv li, yog qhov tsim nyog rau kev kho kom zoo thiab zoo tho txawv nyob rau hauv kev txiav ceev, me me, thiab tsis muaj kev vibration.

Chav Kawm K: Alloy / txheej alloy raws li WC, nrog Co ua tus khi, thiab ntxiv me me ntawm TaC thiab NbC. Nws yog feem ntau siv rau kev ua cov ntaub ntawv luv luv, xws li cam khwb cia hlau, chilled cam khwb cia hlau, luv-chip malleable cam khwb cia hlau, grey cam khwb cia hlau, thiab lwm yam ua;

N-hom: alloy / txheej alloy raws li WC, nrog Co raws li kev khi, thiab ib qho me me ntawm TaC, NbC, lossis CrC ntxiv. Nws feem ntau yog siv los ua cov hlau tsis-ferrous thiab cov khoom tsis yog hlau, xws li txhuas, magnesium, yas, ntoo, thiab lwm yam kev ua;

Chav S: Alloy / txheej alloy raws li WC, nrog Co raws li binder, thiab ib qho me me ntawm TaC, NbC, lossis TiC ntxiv. Nws feem ntau yog siv rau kev ua cov khoom siv hluav taws xob thiab cov khoom siv zoo, xws li cov hlau tsis muaj zog, npib tsib xee- thiab cobalt uas muaj hlau. , ua ntawm ntau yam titanium alloy cov ntaub ntawv;

Qeb H: Alloys / txheej alloys raws li WC, nrog Co raws li cov ntaub ntawv, thiab ib qho me me ntawm TaC, NbC, lossis TiC ntxiv. Lawv feem ntau siv rau kev ua cov ntaub ntawv nyuaj, xws li hardened steel, chilled cam khwb cia hlau, thiab lwm yam ntaub ntawv;

2. Carbide rau geological thiab mining cov cuab yeej: Carbide rau geological thiab mining cov cuab yeej muab faib ua pawg hauv qab no raws li qhov sib txawv ntawm kev siv:

A: Cemented carbide rau pob zeb drilling khoom; kev khiav hauj lwm tej yam kev mob xws li qib GA05, haum rau cov pob zeb mos los yog nruab nrab hard pob zeb nrog ib tug uniaxial compressive zog ntawm tsawg tshaj li 60MPa, qib GA50 / GA60 haum rau uniaxial compressive zog ntawm ntau dua 200MPa nyuaj pob zeb los yog tawv pob zeb; Raws li qib qib nce, qhov hnav tsis kam txo qis thiab toughness nce.

B: Carbide rau kev tshawb nrhiav geological;

C: Cemented carbide rau thee mining;

D: Carbide rau mining thiab roj teb laum khoom;

E: Cemented carbide rau composite sheet matrix;

F: Carbide rau daus daus;

W: Carbide rau khawb cov hniav;

Z: lwm pawg;

Rockwell hardness ntawm hom alloy no tuaj yeem ncav cuag HRA85 thiab siab dua, thiab lub zog flexural feem ntau yog siab dua 1800MPa.

3. Carbide rau qhov hnav-tiv taus: Cov khoom hnav-tiv taus tau muab faib ua

S: Carbide rau kos cov hlau xaim, pas nrig, thiab cov raj, xws li kos duab tuag, sealing rings, thiab lwm yam.

T: Carbide rau stamping tuag, xws li so rau fastener stamping, steel pob stamping, thiab lwm yam.

Q: Carbide rau high-temperature thiab high-pressure Cheebtsam, xws li sab saum toj hammers thiab nias cylinders rau hluavtaws pob zeb diamond.

V: Cemented carbide rau hlau qws dov yob rings, xws li yob rings rau high-speed hlau qws dov xov mills, thiab lwm yam.
