Zvimiro uye Mashandisirwo eCemented Carbide

Zvimiro zve tungsten carbide

Tungsten carbide ine kuomarara kwakanyanya uye kupfeka kuramba. Iyo yekucheka kumhanya kwemidziyo yecarbide ndeye 4 kusvika 7 nguva yakakwirira kupfuura yesimbi inomhanya uye 5 kusvika 80 nguva yehupenyu hwesevhisi hwepamusoro. Zvigadzirwa zveCarbide zvinogona kucheka zvinhu zvakaoma kusvika makumi mashanu HRC. Zvinyorwa zvichaunza imwe ruzivo rwakakosha nezve simende carbide.

Material zvimiro zve tungsten carbide

Cemented carbide inonyanya kuita micro-sized poda yecarbides (WC, TiC) yehurefu-kuoma refractory simbi. Zvikuru zvinoumba upfu metallurgical zvigadzirwa sintered muvacuum muchoto kana hydrogen kuderedza choto pamwe cobalt (Co), nickel (Ni), uye molybdenum (Mo) sebhainda.

Iyo matrix yecemented carbide inoumbwa nezvikamu zviviri: chikamu chimwe chikamu chekuomesa, uye chimwe chikamu isimbi yekubatanidza.

Chikamu chakaomeswa ndeye carbide, senge tungsten carbide, titanium carbide, uye tantalum carbide. Kuoma kwayo kwakanyanya. Kunyungudika kwayo kuri pamusoro pe2000°C, uye mamwe anotodarika 4000°C. Kuvepo kwechikamu chekuoma kunotemesa kuomarara kwakanyanya uye kupfeka kuramba kwecarbide.

Tungsten carbide WC saizi yezviyo zvinodiwa zvesimende carbide shandisa saizi yezviyo zvakasiyana WC zvinoenderana nekushandisa kwakasiyana.

Ichi chinyorwa chinonyanya kuunza matatu kushandiswa kwecemented carbide:

1. Tungsten carbide yekugadzira maturusi ekucheka maturusi

Carbide yekucheka maturusi anoshandiswa zvakanyanya kucheka simbi uye machining. Mapaipi ekugadzira alloys akadai semakumbo ekucheka tsoka uye V-CUT mapanga anoshandisa Ultra-yakanaka, sub-fine, uye yakanaka-grained WC. Huru-machining alloys anoshandisa yepakati-zviyo WC. Gravity yekucheka alloys uye inorema-basa rekucheka alloys anoshandisa yepakati uye yakaoma Granular WC seyakagadzirwa.

2. Cemented carbide yekugadzira maturusi ekuchera carbide

Dombo rine kuoma kwepamusoro uye mutoro wepamusoro. Coarse WC inotambirwa, uye dombo rinoita idiki nemutoro mudiki. Iyo yepakati-saizi WC inoshandiswa seyakagadzirwa zvinhu.

3. Hard alloy yekugadzira carbide kusapfeka-resistant parts

Kana ichisimbisa kupfeka kwayo kuramba, kumanikidza kuramba, uye kupera kwepamusoro, WC ine saizi dzakasiyana inoshandiswa seyakagadzirwa, uye yepakati uye yakaomesesa-grained WC mbishi inoshandiswa sechinhu chikuru.

4. Simbi yakaoma yekugadzira tungsten carbide Inofa

Iyo carbide inofa ine makumi akati wandei enguva yakareba hupenyu hwesevhisi kupfuura mold dzesimbi. Iyo carbide mold ine kuoma kwepamusoro, kusimba kwepamusoro, kushorwa kwecorrosion, kukwira-tembiricha kuramba, uye diki yekuwedzera coefficient, kazhinji inoumbwa netungsten cobalt.

Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi peji.
