Cemented carbide ndeye alloy zvinhu zvakagadzirwa kuburikidza nehupfu metallurgy tekinoroji. Iyo inonyanya kuumbwa neakaomesesa masimbi erefractory simbi uye bonding simbi.

Izvo zvakakosha zvesimende carbide zvinosanganisira refractory carbide poda senge tungsten carbide uye titanium carbide, pamwe nehupfu hwesimbi hunoshandiswa semasungiro, senge cobalt uye nickel. Ichi chinyorwa chinozivikanwa nekuoma kwayo kwepamusoro, kupfeka kusagadzikana, kusimba uye kusimba, kupisa kwekudzivirira uye kusagadzikana kwekuora, kunyanya pakupisa kwepamusoro uchichengetedza zvinhu izvi. Kuomarara uye kupfeka kuramba kwecemented carbide haina kuchinjika pa500 ° C, uye inogona kuramba yakaomarara pa1000 ° C. Naizvozvo, inoshandiswa zvakanyanya mukugadzira maturusi ekucheka, maturusi ekuchera, maturusi ekuyeresa, inotonhora basa molds uye akasiyana-siyana anopotera zvikamu.

Ichi chinyorwa chinozivikanwa nekuoma kwayo kwepamusoro, kupfeka kusagadzikana, kusimba uye kusimba, kupisa kwekudzivirira uye kusagadzikana kwekuora, kunyanya pakupisa kwepamusoro uchichengetedza zvinhu izvi. Kuomarara uye kupfeka kuramba kwecemented carbide haina kuchinjika pa500 ° C, uye inogona kuramba yakaomarara pa1000 ° C. Naizvozvo, inoshandiswa zvakanyanya mukugadzira maturusi ekucheka, maturusi ekuchera, maturusi ekuyeresa, inotonhora basa molds uye akasiyana-siyana anopotera zvikamu.

Iine zvinhu zvinotevera zvinokosha:

1. Kuomarara kwepamusoro: Kuomarara kwecemented carbide kunowanzo kukwirira zvakanyanya kupfuura izvo zvezvinhu zvakajairika zvesimbi, izvo zvinoita kuti zvinyatso shingirira kupfeka nekucheka. (Kazhinji pakati pe80HRA-94HRA)

2. Simba rakakwirira: Carbide ine simba guru, inogona kutsungirira kudzvinyirira kukuru uye mutoro, uye haisi nyore kukanganisa kana kuputsa. (Kazhinji TRS pakati pe2000-3200 Mpa)

3. Pfeka kuramba: Nekuda kwekuoma kwayo kwakanyanya, carbide ine yakanakisa kupfeka kusagadzikana uye inokodzera zvikumbiro zvinoda kureba kupfeka kusagadzikana.

4. Corrosion resistance: Carbide ine kupikisa kwakanaka kune yakawanda corrosive media uye inogona kuchengetedza kushanda kwayo munzvimbo dzakaoma.

5. Kugadzikana kwekushisa kwepamusoro: Inogona kuchengetedza zvinhu zvayo zvepanyama uye zvemakemikari pakupisa kwepamusoro uye haisi nyore kupfava kana kukanganisa.

6. Yakanaka magetsi uye inopisa conductivity: Imwe simende carbide ine yakanaka magetsi uye thermal conductivity, zvichiita kuti zvive zvakakosha muminda yemagetsi uye kutonga kwekushisa.

Izvi zvivakwa zvinogadzira simende carbide inoshandiswa zvakanyanya mukugadzira maturusi, machining, aerospace, petrochemical nemamwe minda. Mhando dzakasiyana dzecarbide dzinogona kugadziridzwa kuti isangane nezvido zvekuita nekugadzirisa kuumbwa uye kugadzira maitiro. Nekudaro, maitiro chaiwo ekuita anogona kusiyana zvichienderana nekuumbwa kwecarbide, chimiro uye maitiro ekugadzira. Mumashandisirwo anoshanda, akakodzera carbide zvinhu zvinoda kusarudzwa zvinoenderana nemamiriro ekushandisa uye zvinodiwa.

CD carbide inyanzvi mune tungsten carbide zvigadzirwa senge kupfeka kuramba chikamu, maturusi emigodhi, maturusi ekucheka uye zvichingodaro.
