Cemented Carbide yog hmoov metallurgy khoom sintered los ntawm siab hardness, refractory hlau compound hmoov (xws li WC, TiC, TaC, NbC thiab lwm yam high-kub carbides) thiab hlau binder (Co, Mo, Ni, thiab lwm yam).Raws li cov muaj pes tsawg leeg ntawm Cemented Carbide muaj ntau cov carbides siab melting point, siab hardness thiab zoo tshuaj stability, hardness, hnav tsis kam thiab kub tsis kam ntawm Cemented Carbide yog siab heev.Chav tsev kub hardness ntawm Cemented Carbide feem ntau yog 89 ~ 93HRA, uas yog sib npaug rau 78 ~ 82HRC, thiab qhov tso cai txiav kub yog siab li 800 ℃ ~ 1000 ℃, thiab nws hardness tseem tseem nyob 77 ~ 85HRA txawm nyob ntawm 540 ℃, uas yog sib npaug rau chav tsev kub hardness ntawm high-speed steel.
Yog li ntawd, qhov kev ua tau zoo ntawm Cemented Carbide yog ntau dua li ntawm HSS, nyob rau hauv tib lub sijhawm, kev txiav ceev ntawm Cemented Carbide raug tso cai rau 4 zaug mus rau 10 npaug siab dua li ntawm HSS, thiab kev txiav ceev tuaj yeem ncav cuag ntau dua. 100m / min, thiab nws tuaj yeem txiav txhua yam ntawm cov ntaub ntawv nyuaj rau lub tshuab, xws li cov hlau tawv tawv, uas tsis tuaj yeem txiav los ntawm HSS cov cuab yeej txiav.Txawm li cas los xij, vim nws tsis tshua muaj zog dabtsi yog khoov (li 1/2 ~ 1/4 ntawm HSS), cuam tshuam toughness (kwv yees (1/8 ~ 1/30) ntawm HSS) thiab kev ua haujlwm tsis zoo, yog li tam sim no, Cemented Carbide cov ntaub ntawv yog feem ntau yog siv nyob rau hauv zus tau tej cov non-intermittent txiav thiab machining cov cuab yeej nrog yooj yim ntug zoo li thiab tsis muaj kev cuam tshuam.Thaum cov ntsiab lus carbide nyob rau hauv cov cemented carbide siab, lub hardness yog siab, tab sis lub zog flexural kuj tsawg;Thaum cov ntsiab lus binder siab, lub zog flexural yog siab thiab hardness tsawg.ISO yuav muab faib ua P, K thiab M peb pawg ntawm cemented carbide, cov khoom tseem ceeb ntawm peb pawg ntawm cemented carbide yog WC, thiaj li hu ua WC-based cemented carbide.
K chav kawm yog sib npaug rau Tuam Tshoj tungsten-cobalt cemented carbide, code lub npe YG, feem ntau yog tsim los ntawm WC thiab Co.
YG hom cemented carbide dabtsi yog khoov lub zog thiab cuam tshuam toughness yog zoo dua, haum rau nkig cov ntaub ntawv ua, yuav siv tau rau cam khwb cia hlau, non-ferrous hlau thiab lawv cov alloys thiab non-metallic cov ntaub ntawv ua.YG hom cemented carbide nrog nce ntawm cobalt cov ntsiab lus, nws hardness txo qis, thaum lub zog khoov nce, muaj peev xwm tiv taus qhov cuam tshuam ntawm kev txhim kho ntawm roughing, haum rau kev ntxhib machining.Ntawm qhov tsis sib xws, hardness, hnav tsis kam thiab kub ua haujlwm nce, haum rau kev ua tiav.
P chav kawm yog sib npaug rau Tuam Tshoj tungsten, cobalt thiab titanium cemented carbide, code lub npe YT, nws muaj pes tsawg leeg ntxiv rau WC thiab Co, tab sis kuj muaj 5% ~ 30% ntawm TiC, vim hais tias lub hardness thiab melting point ntawm TiC yog siab tshaj WC. , yog li lub hardness, hnav tsis kam thiab kub tsis kam ntawm cov cemented carbides yog siab tshaj YG chav kawm, thiab lub zog khoov thiab cuam tshuam toughness tsawg dua.Nrog rau qhov nce ntawm TiC cov ntsiab lus, qhov hardness, kub tsis kam thiab hnav tsis kam ntawm cov khoom siv tau zoo dua thiab zoo dua, thaum lub zog dabtsi yog khoov thiab qhov cuam tshuam toughness txo.
YT hom cemented carbide feem ntau tuaj yeem siv rau kev kub ceev txiav cov hlau.
M chav kawm yog sib npaug rau Tuam Tshoj tus tungsten-titanium-tantalum (niobium) cobalt cemented carbide, codenamed YW chav kawm, uas yog ntxiv ib co ntsiab lus ntawm TaC los yog NbC nyob rau hauv cov muaj pes tsawg leeg ntawm cov saum toj no cemented carbide nyob rau hauv thiaj li yuav txhim kho lub high-temperature hardness, high-temperature zog thiab abrasion tsis kam ntawm cov cemented carbide khoom.
YW chav kawm yog tus cwj pwm los ntawm: kev ua tau zoo tag nrho, ntau yam kev siv, tuaj yeem siv tau rau txhua yam ntawm cov hlau cam khwb cia, hlau, stainless hlau thiab kub kub alloy ua.
Nrog rau kev tshwm sim tas mus li ntawm ntau yam ultra-fine grain cemented carbide thiab coated cemented carbide cov ntaub ntawv, kev ua tau zoo ntawm cemented carbide cov ntaub ntawv tau zoo heev, thiab lub zog flexural, cuam tshuam toughness thiab hnav tsis kam ntawm cemented carbide tau zoo tuaj, thiab cemented carbide. kuj tau pib siv ntau ntau hauv kev ua haujlwm ntawm cov cuab yeej txiav, xws li tho, reamers, kais, milling cutters, hobs, thiab broaches, thiab lwm yam, uas tau pib ua nrog ntau cov ntaub ntawv cemented carbide. .
Peb lub tuam txhab tsuas yog tsim cov ntaub ntawv Carbide Rotary, Carbide rods, Carbide Scraper Hniav, Carbide Corrugated Slitter Riam, Carbide Woodworking Hloov Hniav thiab lwm yam Cemented Carbide khoom.
