Nzira yekugadzira tungsten carbide

Tungsten carbidemusanganiswa unoumbwa ne tungsten uye kabhoni.Kuoma kwayo kwakafanana nedhaimani.Zvimiro zvaro zvemakemikari zvakagadzikana zvakanyanya uye zvinonyanya kufarirwa munzvimbo dzakasiyana siyana dzeindasitiri.Nhasi, Sidi Xiaobian achataura newe nezve nzira yekugadzira tungsten carbide.

Maererano nezvinodiwa netungsten carbide rollersaizi, saizi dzakasiyana dzetungsten carbide dzinoshandiswa kune zvinangwa zvakasiyana.Carbide yekucheka maturusi, akadai sekucheka muchina blade V-yakaita sekucheka maturusi, yakanaka alloy ine Ultrafine subfine tungsten carbide zvimedu.Coarse alloy uchishandisa yepakati particle tungsten carbide;Iyo alloy yekucheka giravhiti uye inorema yekucheka inogadzirwa nepakati coarse tungsten carbide.Dombo rinoshandiswa pazvishandiso zvemigodhi rine kuomarara kwakanyanya uye mitoro yekukanganisa uye rinoshandisa coarse tungsten carbide.Diki dombo rinokanganisa, diki rinokanganisa mutoro, ine yepakati particle tungsten carbide seyakagadzirwa zvinhu kupfeka-inodzivirira zvikamu;Mukusimbisa kupfeka kuramba, kumanikidza kuramba uye kutsvedzerera kwepasi, Ultrafine yepakati chidimbu chetungsten carbide inoshandiswa seyakabikwa.Iyo yekukanganisa chishandiso inonyanya kushandisa yepakati uye yakaomarara tungsten carbide mbishi zvinhu.

Tungsten carbide ine theoretical carbon content ye6.128% (50% atomic).Kana iyo kabhoni ye tungsten carbide yakakura kupfuura theoretical kabhoni yemukati, yemahara kabhoni inoonekwa mu tungsten carbide.Kuvapo kwekabhoni yemahara kunoita kuti tungsten carbide zvidimbu zvakatenderedza zvikure panguva yekunyungudika, zvichikonzera kusaenzana kwemasimende ecarbide particles.Tungsten carbide inowanzoda yakakwira yakasungwa kabhoni (≥6.07%) uye yemahara kabhoni (≤0.05%), nepo yakazara kabhoni zvinoenderana nemaitiro ekugadzira uye mashandisirwo emhando yesamende carbide.

Mumamiriro ezvinhu akajairwa, iyo yakazara kabhoni yevacuum sintering tungsten carbide nenzira yeparafini inonyanya kutariswa neiyo yakazara oksijeni yemukati yebriquette isati yanyura.Chikamu chemukati weokisijeni chakawedzera ne 0.75 chikamu, kureva, iyo yakazara kabhoni ye tungsten carbide = 6.13% + okisijeni yemukati % × 0.75 (tichifunga kuti kune mhepo isina kwayakarerekera muchoto che sintering, chokwadi, iyo yakazara kabhoni ye tungsten carbide mu mavira mazhinji evacuum ishoma pane yakaverengerwa kukosha) [4] Yese kabhoni yemukati yeChina tungsten carbide inogona kukamurwa kuita matatu eparafini maitiro.

Vacuum sintered tungsten carbide ine yakazara kabhoni yemukati inosvika 6.18±0.03% (yemahara kabhoni ichawedzera).Iyo yakazara kabhoni yeparafini wax hydrogen sintering tungsten carbide i6.13±0.03%.Iyo yakazara kabhoni yemukati yerabha hydrogen sintering tungsten carbide ndeye 5.90±0.03%.Aya maitiro dzimwe nguva anochinjana.Naizvozvo, iyo yakazara kabhoni yemukati tungsten carbide inotarwa zvichienderana nemamiriro chaiwo.
