Magawo Anayi Akuluakulu a Chithandizo cha Tungsten Carbide Heat

Tungsten carbide imagwira ntchito kwambiri yokhala ndi makina abwino kwambiri komanso mawonekedwe akuthupi, kuphatikiza kukana kwamphamvu kwambiri, kukana dzimbiri, mphamvu yopindika, mphamvu ya torsion, etc., yomwe imagwiritsidwa ntchito kwambiri podulira zida, nkhungu zozizira, mavalidwe, ndi zina. Nkhaniyi ikufotokozanso mwachidule zinayizi. magawo akuluakulu a tungsten carbide kutentha mankhwala, amene angathe kusintha thupi ndi makina zimatha aloyi zolimba.

Njira yochizira kutentha kwa tungsten carbide imatha kugawidwa m'magawo anayi akuluakulu.

1. Kuchotsa akamaumba zinthu ndi chisanadze sintering

Pa gawo loyambirira la sintering, wopangirayo amawola pang'onopang'ono kapena amatuluka nthunzi, kupatula thupi lomwe silinasinthidwe, nthawi yomweyo, omwe amapanga ma sintering, ndipo kuchuluka kwa kaboni kumasiyana kutengera mtundu, kuchuluka kwake, ndi njira ya sintering. . Powder surface oxide imachepetsedwa, ndipo haidrojeni imatha kuchepetsa cobalt ndi tungsten oxides pa kutentha kwa sintering. Ndi chofooka chochita pakati pa carbon ndi mpweya, kukhudzana kukhudzana pakati pa ufa particles kumachotsedwa pang'onopang'ono. Kulumikizana kwachitsulo ufa kumayamba kuyankha ndi recrystallization ndi kufalikira kwa pamwamba kumayamba kuchitika. Mphamvu ya block yawonjezeka.

2. Stage of solid-phase sintering (800°C - kutentha kwa eutectic)

Pamaso pa gawo lamadzimadzi, kuwonjezera pa njira yopititsira patsogolo gawo lapitalo, machitidwe olimba ndi kufalikira kumakulitsidwa ndikuwonjezeka kwa pulasitiki, ndipo kutsika kowoneka bwino kumawoneka m'thupi la sintered.

3. Gawo la madzi-gawo sintering (kutentha kwa eutectic - sintering kutentha)

Pamene gawo lamadzimadzi la thupi la sintered likuchitika, kupanikizika kumatsirizika mwamsanga, ndiyeno kusintha kwa crystallization kumachitika. Bungwe loyambira ndi kapangidwe ka carbide amapangidwa.

4. Kuzizira siteji (sintering kutentha - chipinda kutentha)

Panthawiyi, zigawo zamagulu ndi gawo la tungsten carbide zimasintha pazikhalidwe zosiyanasiyana zoziziritsa, zomwe zimapangitsa kugwiritsa ntchito izi; kutentha mankhwala a aloyi zolimba adzakhala bwino thupi ndi makina makhalidwe.

ZZBETTER imadzipereka popanga zinthu zapamwamba komanso zapamwamba kwambiri za tungsten carbide. Zogulitsa zathu zagulitsidwa kumayiko ndi madera ambiri komanso zikuyenda bwino kwambiri pamsika wapakhomo.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZANI MAIME pansi pa tsamba.
