Nā hopena wili pulu no nā hui karbida sima

ʻO ke kumu o ka milling pulu ʻo ka wili ʻana i ka pauka tungsten carbide i ka nui o ka ʻāpana i makemake ʻia, e hoʻokō i ka hui pū ʻana me ka pauka cobalt i loko o kekahi ʻāpana, a loaʻa i nā waiwai paʻi a me ka sintering. Hoʻohana nui kēia kaʻina hana wili i ka pōpō tungsten carbide a me ke ʻano o ka ʻōwili ʻana i ka waiʻona.

He aha nā hopena wili pulu no ka hui pū ʻana o tungsten carbide?

1. Huihui

Aia nā ʻāpana like ʻole i ka hui ʻana, a ʻokoʻa hoʻi ka mānoanoa a me ka nui o kēlā me kēia ʻāpana. No ka loaʻa ʻana o nā huahana carbide cemented kiʻekiʻe, hiki i ka milling wīwī ke hōʻoia i ka māhele like ʻana o nā ʻāpana o ka hui.

2. Kuʻi ʻana

ʻOkoʻa nā kikoʻī nui o nā mea maka i hoʻohana ʻia i ka hui ʻana, ʻoi aku ka nui o ka WC i loaʻa kahi ʻano agglomerate. Eia kekahi, ma muli o nā pono maoli o ka hana a me ka hana ʻana, hui pinepine ʻia ka WC o nā māka like ʻole a me nā ʻāpana. Ke alakaʻi nei kēia mau ʻano ʻelua i kahi ʻokoʻa nui i ka nui o nā mea maka, ʻaʻole kūpono i ka hana kiʻekiʻe o nā alloys. Hiki i ka wili pulu ke pāʻani i ke ʻano o ka wāwahi ʻana i nā mea a me ka homogenization nui.

3. Oxygenation

ʻO ka hui ʻana a me ka hakakā ma waena o ka hui ʻana, ka wili wili, a me nā pōlele wili ʻoi aku ka maʻalahi i ka oxidation. Eia kekahi, hoʻonui ka wai i loko o ka waiʻona milling medium i ka hopena oxygenation. ʻElua mau ala e pale aku ai i ka oxygenation: ʻo ka hoʻomaloʻo ʻana, ma ka hoʻohui ʻana i kahi ʻaʻahu wai hoʻoluʻu ma waho o ka pahu o ka wili kinipōpō e mālama ai i ka mahana i ka wā e hana ai ka wili kinipōpō; ʻo ka mea ʻē aʻe e koho i kahi kaʻina hana kūpono, e like me ka mea mahiʻai organik a me nā mea makapō pōlele hui pū ʻia no ka mea ʻo nā mea hoʻokumu organik e hana i kahi kiʻiʻoniʻoni pale ma ka ʻili o ka mea maka, nona ka hopena o ka hoʻokaʻawale ʻana i ka oxygen.

4. Ho'ola

I ke kaʻina o ka wili pōleʻa, ma muli o ke kuʻi ʻana a me ka friction, hiki ke hoʻololi a hoʻololi ʻia ka lattice kristal o ka pauka, a piʻi ka ikehu o loko. He mea maikaʻi kēia hoʻoulu ʻana i ka sintering shrinkage a me ka densification, akā maʻalahi nō hoʻi ke kumu "haehae", a laila ulu ʻole i ka wā o ka sintering.

I mea e hōʻemi ai i ka hopena hoʻāla, ʻaʻole pono e lōʻihi ka wili pulu. A koho i ka manawa wili pulu kūpono e like me ka nui o ka ʻāpana o ka hui.

Inā makemake ʻoe i nā huahana tungsten carbide a makemake ʻoe i ka ʻike hou aʻe a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole leka uila ma ka hema, a i ʻole SEND US MAIL ma lalo o ka ʻaoʻao.
