Zitenga Nthawi Yaitali Bwanji Kupanga Ndodo Za Carbide?

Monga opanga ndodo za tungsten carbide, nthawi zonse timalandira mafunso angapo monga, "n'chifukwa chiyani zimatenga nthawi yaitali kuti apange ndodo za carbide?". Nkhaniyi ikukupatsani yankho, ndipo titenga zitsanzo zopanga mipiringidzo yozungulira ya 200kg carbide.

Njira yopangira ndodo za tungsten carbide

A. Konzani zopangira

Nthawi zambiri, dipatimenti yogula imagula ndikusunga ufa wapamwamba kwambiri wa tungsten carbide ndi binder ufa.

B. Kusakaniza ndi mphero yonyowa: maola 48

Tungsten carbide ufa ndi binder ufa adzasakanizidwa ndi kugayidwa ndi madzi ndi Mowa mu makina mphero. Kuti mpheroyo mokwanira ndikukwaniritsa kukula kwake kwambewu, makina ophera mpira amasunga mphero kwa masiku awiri.

C. Utsi kuyanika: 24 maola

Pambuyo pa mphero yonyowa, tungsten carbide powder slurry Dryskwa maola 24 mumtsuko wowuma. Pokhapokha pamene kuyanika kwa utsi kumatulutsa nthunzi madzi mu tungsten carbide ufa ndi pamene kukanikiza ndi sintering kutha bwino.

D. Kuphatikiza: extrusion 228 hours; youma-thumba isostatic kukanikiza 36 maola (kuphatikiza kutulutsa kupsinjika kwamkati ndi kuyanika)

Njira ziwiri zazikulu zakupangandi extrusion ndi dry-thumba isostatic kukanikiza. Njira ziwirizi zidzatengera nthawi zosiyanasiyana. Extrusion idzatenga maola 12 kuti igwirizane, ndipo kukanikiza kowuma kwa isostatic kudzatenga maola 8. Panthawi ya kukanikiza, chopangiracho chimawonjezedwa panthawi ya extrusion, pomwe thumba lowuma la isostatic silifuna wopangira.

Pambuyo kukanikiza, ndodo zophatikizika zimayenera kumasula kupsinjika kwamkati pansi pa kutentha kosalekeza ndi chinyezi. Njirayi ingapewe ming'alu m'njira zotsatirazi. Ndodo zophatikizika za Tungsten carbide zitha nthawi yayitali kutulutsa kupsinjika kwamkati, maola 144 pakutulutsa, ndi maola 24 pakukanikiza kwachikwama cha isostatic. Ndiye tungsten carbide tikaumbike ndodo, pambuyo extrusion, adzaikidwa mu ng'anjo kuyanika kwa maola 73, ndi ndodo pambuyo youma thumba isostatic kukanikiza kwa maola 4 okha.

Ngakhale kukanikiza kwachikwama kwa isostatic kumawononga nthawi yochepa kuposa kutulutsa, kumatha kugwira ntchito popanga ndodo zazikulu zokhala ndi mainchesi opitilira 16mm.

E. Sintering: 24 maola

Ndodo zophatikizika za Tungsten carbide zidzawotchedwa mu ng'anjo yopuma. Izi zitha pafupifupi maola 24. Pambuyo sintering, tungsten carbide ndodo akusowekapo ayenera akupera ndi anayendera.

Mwachidule, njira yayikulu yopangira 200kg tungsten carbide rod 200kg idzatenga pafupifupi maola 324 (masiku 13.5) kwa extrusion ndi pafupifupi maola 132 (masiku 5.5) kwa dry-thumba isostatic kukanikiza, osatchulapo nthawi yopera ndi kugaya. zina zotero.

Komabe, pokhala ndi katundu wokwanira, simuyenera kudandaula za nthawi yobereka. Titha kutumiza m'masiku atatu. 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.
