Njira yopangira tungsten carbide

Tungsten carbidendi gulu lopangidwa ndi tungsten ndi carbon.Kuuma kwake kumafanana ndi diamondi.Mankhwala ake ndi okhazikika kwambiri ndipo amadziwika kwambiri m'mafakitale osiyanasiyana.Lero, Sidi Xiaobian alankhula nanu za njira yopangira tungsten carbide.

Malinga ndi zofunikira zatungsten carbide rollerkukula, makulidwe osiyanasiyana a tungsten carbide amagwiritsidwa ntchito pazolinga zosiyanasiyana.Zida zodulira za Carbide, monga zida zodulira makina odulira zooneka ngati V, aloyi yabwino yokhala ndi tinthu tating'onoting'ono tating'onoting'ono ta tungsten carbide.coarse aloyi ntchito sing'anga tinthu tungsten carbide;Aloyi yodula mphamvu yokoka ndi kudula kolemera kumapangidwa ndi sing'anga coarse tungsten carbide.Mwala womwe umagwiritsidwa ntchito pazida zamigodi umakhala wolimba kwambiri komanso wonyamula katundu ndipo umagwiritsa ntchito coarse tungsten carbide.Small thanthwe zimakhudza, katundu waung'ono, ndi sing'anga tinthu tungsten carbide monga zopangira avale zosagwira mbali;Pogogomezera kukana kuvala, kukana kukakamiza komanso kusalala kwa pamwamba, ultrafine ultrafine medium particle tungsten carbide imagwiritsidwa ntchito ngati zopangira.Chida chothandizira makamaka chimagwiritsa ntchito zinthu zapakatikati komanso zolimba za tungsten carbide.

Tungsten carbide ili ndi theoretical carbon content ya 6.128% (50% atomiki).Pamene mpweya wa tungsten carbide umakhala waukulu kuposa mpweya wa carbon, mpweya waulere umapezeka mu tungsten carbide.Kukhalapo kwa kaboni waulere kumapangitsa kuti tinthu tating'onoting'ono ta tungsten carbide tikule kukula panthawi ya sintering, zomwe zimapangitsa tinthu tating'ono ta carbide tosafanana.Tungsten carbide nthawi zambiri imafuna mpweya womangidwa kwambiri (≥6.07%) ndi kaboni waulere (≤0.05%), pomwe mpweya wokwanira umadalira kapangidwe kake komanso kagwiritsidwe kake ka carbide yomangidwa.

M'mikhalidwe yachibadwa, okwana mpweya wa zingalowe sintering tungsten carbide ndi parafini njira makamaka anatsimikiza ndi okwana mpweya zili briquette pamaso sintering.Gawo la mpweya wa okosijeni linawonjezeka ndi gawo la 0.75, ndiye kuti, carbon of tungsten carbide = 6.13% + mpweya wa okosijeni % × 0.75 (poganiza kuti pali mpweya wosalowerera mu ng'anjo yotentha, makamaka carbon ya tungsten carbide mu ng'anjo za vacuum zambiri ndizocheperapo mtengo wowerengeka) [4] Mphamvu zonse za carbon tungsten carbide yaku China zitha kugawidwa m'njira zitatu za parafini.

Vacuum sintered tungsten carbide imakhala ndi mpweya wokwanira pafupifupi 6.18±0.03% (carbon yaulere idzawonjezeka).Mpweya wonse wa paraffin wa sera wa hydrogen sintering tungsten carbide ndi 6.13±0.03%.Mpweya wonse wa mphira wa hydrogen sintering tungsten carbide ndi 5.90±0.03%.Njirazi nthawi zina zimasinthana.Chifukwa chake, kuchuluka kwa kaboni wa tungsten carbide kumatsimikiziridwa malinga ndi momwe zinthu zilili.
