Kev siv dav ntawm cemented carbide

Koj puas paub qhov kev ua tau zoo ntawm cemented carbide?

Siab hardness (86-93HRA, sib npaug rau 69-81HRC);

Zoo thermal hardness (tuaj yeem ncav cuag 900-1000 ℃, tswj 60HRC);

Zoo hnav tsis kam.

Kev txiav ceev ntawm cov cuab yeej carbide yog 4 mus rau 7 npaug siab dua li cov hlau ceev ceev, thiab cov cuab yeej lub neej yog 5 mus rau 80 npaug ntev dua. Rau kev tsim pwm thiab ntsuas cov cuab yeej, lub neej yog 20 mus rau 150 lub sij hawm ntev dua li cov cuab yeej hlau alloy. Nws tuaj yeem txiav cov ntaub ntawv nyuaj txog li 50HRC.

Txawm li cas los xij, cemented carbide yog nkig heev thiab tsis tuaj yeem txiav. Nws yog ib qho nyuaj rau ua kom nws mus rau hauv ib tug complex integral cuab tam. Yog li ntawd, nws yog feem ntau ua rau cov hniav ntawm cov duab sib txawv thiab ntsia rau ntawm lub cuab yeej los yog pwm lub cev los ntawm vuam, kev sib txuas, tshuab clamping, thiab lwm yam.

Cov khoom siv hlau ua los ntawm cov khoom siv tawv tawv ntawm cov hlau refractory thiab cov hlau sib txuas los ntawm cov hmoov hlau metallurgy. 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 tsis kam yog qhov tseem ceeb tsis hloov txawm nyob rau ntawm qhov kub ntawm 500 ° C, thiab nws tseem muaj qhov nyuaj siab ntawm 1000 ° C.

Cemented carbide yog dav siv los ua cov cuab yeej siv, xws li cov cuab yeej tig, milling cutters, planers, xyaum, tho txawv cov cuab yeej, thiab lwm yam, rau txiav hlau cam khwb cia hlau, non-ferrous hlau, yas, tshuaj fibers, graphite, iav, pob zeb thiab zoo tib yam hlau. Nws tseem tuaj yeem siv los txiav cov hlau tsis muaj cua sov, cov hlau tsis muaj steel, siab manganese hlau, cov cuab yeej hlau thiab lwm yam khoom siv nyuaj. Tam sim no qhov kev txiav ceev ntawm cov cuab yeej cemented carbide tshiab yog ntau pua zaus ntawm cov hlau. Nws muaj cov khoom zoo heev xws li siab hardness, hnav tsis kam, zoo zog thiab toughness, kub tsis kam, corrosion kuj, thiab lwm yam, tshwj xeeb tshaj yog nws cov hardness siab thiab hnav tsis kam, uas tseem nyob twj ywm tsis hloov txawm nyob rau hauv kub ntawm 500 ° C, thiab tseem muaj ib tug siab hardness ntawm 1000 ° C.

Cemented carbide yog dav siv los ua cov cuab yeej cuab tam, xws li cov cuab yeej tig, milling cutters, planers, xyaum, tho txawv cov cuab yeej, thiab lwm yam, rau txiav hlau cam khwb cia hlau, non-ferrous hlau, yas, tshuaj fibers, graphite, iav, pob zeb thiab zoo tib yam hlau, thiab kuj yuav siv tau los txiav kub-resistant steel, stainless hlau, siab manganese steel thiab lwm yam khoom nyuaj. Tam sim no qhov kev txiav ceev ntawm cov cuab yeej cemented carbide tshiab yog ntau pua zaus ntawm cov hlau.
