Mea Paahana Oki Carbide Sima

ʻO Tungsten carbide ka papa hana hoʻohana nui ʻia o nā mea hana kiʻekiʻe kiʻekiʻe (HSM), hana ʻia ia mau mea e ka pauka metallurgy kaʻina, ʻo ia ka carbide paʻakikī (maʻamau ʻo tungsten carbide WC) a me ka paʻa metala palupalu. I kēia manawa, aia nā haneli o nā ʻāpana like ʻole o WC-based cemented carbide, ʻo ka hapa nui o lākou e hoʻohana i ka cobalt (Co) ma ke ʻano he paʻa, ʻo ka nickel (Ni) a me ka chromium (Cr) ka mea maʻamau i hoʻohana ʻia i nā mea hoʻopaʻa paʻa, me ka hoʻohui ʻana i kekahi mau alloying. hiki ke hoʻohui ʻia nā mea. No ke aha i nui ai nā māka carbide sima? Pehea e koho ai ka mea hana mea hana oki i ka mea paahana pono no ka hana oki? No ka pane ʻana i kēia mau nīnau, e nānā mua kākou i nā waiwai like ʻole e hoʻolilo i ka carbide cemented i mea paahana ʻoki kūpono.

ʻO ka paʻakikī a me ka paʻakikī:Loaʻa i ka WC-Co carbide nā pono kūʻokoʻa i ka paʻakikī a me ka paʻakikī. ʻO Tungsten carbide (WC) ponoʻī he kiʻekiʻe ka paʻakikī (ʻoi aku ma mua o ka corundum a i ʻole alumina), a ʻaʻole e emi ka paʻakikī i ka wā e piʻi ai ka mahana hana. Eia naʻe, ʻaʻole lawa ka paʻakikī, he waiwai nui ia no ka ʻoki ʻana i nā mea hana. I mea e hoʻohana pono ai i ka paʻakikī kiʻekiʻe o ka tungsten carbide a hoʻomaikaʻi i kona paʻakikī, hoʻohana nā kānaka i nā mea hoʻopaʻa metala e hoʻohui pū i ka tungsten carbide, i ʻoi aku ka paʻakikī o kēia mea ma mua o ke kila kiʻekiʻe, a ma ka manawa like hiki. pale i ka ikaika ʻokiʻoki i ka nui o nā kaʻina ʻoki. Eia kekahi, hiki iā ia ke pale i nā mahana ʻoki kiʻekiʻe i hana ʻia e ka mīkini kiʻekiʻe.

I kēia lā, ʻaneʻane pau nā mea hana a me nā lau WC-Co i uhi ʻia, no laila, ʻaʻole koʻikoʻi ka hana o ka mea kumu. Akā ʻo ka mea ʻoiaʻiʻo, ʻo ia ka coefficient elastic kiʻekiʻe o ka mea WC-Co (kahi ana o ka ʻoʻoleʻa, ʻo ka elastic coefficient o ka lumi wela o WC-Co e pili ana i ʻekolu mau manawa o ke kila kiʻekiʻe) e hāʻawi ana i ka uhi me ka non-deformation. kumu. Hāʻawi pū ka WC-Co matrix i ka paʻakikī i koi ʻia. ʻO kēia mau waiwai nā waiwai kumu o nā mea WC-Co, akā hiki nō ke hoʻopilikino i nā waiwai waiwai ma o ka hoʻoponopono ʻana i ka haku mele a me ka micro-structure i ka wā e hana ai i ka pauka carbide cemented. No laila, ʻo ke kūpono o nā waiwai mea paahana no kahi kaʻina hana e hilinaʻi nui ʻia i ka hana pulverizing mua.

No ka hoʻopau ʻana, he mea nui ka ʻike kumu o kēlā me kēia mea hana ʻoki a me kāna hana i ka wā e koho pono ai. E noʻonoʻo ʻia ka ʻāpana hana e mīkini ʻia, ke ʻano a me ke ʻano, nā kūlana mīkini a me ka pae o ka maikaʻi o ka ʻili e pono ai no kēlā me kēia hana. ʻIke ʻia, he koho maikaʻi ka cemented no ka hana ʻana i nā mea hana ʻoki, ʻo ZZBETTER Carbide Tools Company i ʻoi aku ma mua o ʻumi mau makahiki o ka ʻike no ka hana ʻana i nā ʻano mea hana tungsten carbide.

Welina mai e leka uila iā mākou inā he nīnau a koi paha ʻoe e pili ana i nā mea hana carbide cemented, hiki iā mākou ke hana i nā huahana non-standardized wale nō inā hāʻawi ʻoe i kāu mau kaha kiʻi.
