ʻO Cemented Carbide kahi huahana metallurgy pauka i hoʻopaʻa ʻia mai ka paʻakikī kiʻekiʻe, refractory metala hui pauka (e like me WC, TiC, TaC, NbC a me nā carbide wela kiʻekiʻe) a me ka mea hoʻopaʻa metala (Co, Mo, Ni, etc.).E like me ka haku mele ʻana o Cemented Carbide i loko o ka nui o nā carbide me ka helu heheʻe kiʻekiʻe, ka paʻakikī kiʻekiʻe a me ke kūpaʻa kemika maikaʻi, ʻo ka paʻakikī, ke kūpaʻa a me ka pale wela o Cemented Carbide he kiʻekiʻe loa.ʻO ka paʻakikī o ka lumi wela o Cemented Carbide ka mea maʻamau 89 ~ 93HRA, ʻo ia ka mea e like me 78 ~ 82HRC, a ʻo ke kiʻekiʻe o ka ʻoki ʻana i ʻae ʻia e like me 800 ℃ ~ 1000 ℃, a mau nō kona paʻakikī 77 ~ 85HRA a hiki i 540 ℃, ka mea. ua like ia me ka paʻakikī o ka mahana wela o ke kila kiʻekiʻe.
No laila, ʻoi aku ka kiʻekiʻe o ka hana ʻoki ʻana o Cemented Carbide ma mua o ka HSS, ma lalo o ka lōʻihi like, ʻae ʻia ka wikiwiki ʻoki ʻana o Cemented Carbide e 4 mau manawa a 10 mau manawa kiʻekiʻe ma mua o ka HSS, a hiki i ka wikiwiki ʻoki ke piʻi aku ma mua o 100m / min, a hiki iā ia ke ʻoki i nā ʻano mea paʻakikī a pau, e like me ke kila paʻakikī, ʻaʻole hiki ke ʻoki ʻia e nā mea hana ʻoki HSS.Eia naʻe, ma muli o kona ikaika kulou haʻahaʻa (e pili ana i ka 1/2 ~ 1/4 o HSS), ka paʻakikī o ka hopena (e pili ana i (1/8 ~ 1/30) o HSS) a me ka hana maikaʻi ʻole, no laila, i kēia manawa, nā mea Cemented Carbide. hoʻohana nui ʻia i ka hana ʻana i ka ʻoki ʻoki ʻole a me nā mea hana mīkini me ke ʻano maʻalahi a ʻaʻohe hopena.Ke kiʻekiʻe ka maʻiʻo carbide i loko o ka carbide cemented, kiʻekiʻe ka paʻakikī, akā haʻahaʻa ka ikaika flexural;ke kiʻekiʻe ka mea paʻa, kiʻekiʻe ka ikaika wili a haʻahaʻa ka paʻakikī.E hoʻokaʻawale ʻia ʻo ISO i P, K a me M ʻekolu mau ʻāpana o ka carbide cemented, ʻo ka mea nui o nā ʻano ʻekolu o ka carbide cemented he WC, no laila i kapa ʻia ʻo WC-based cemented carbide.
Ua like ka papa K me ka carbide cemented tungsten-cobalt o Kina, ka inoa code YG, ka mea nui o WC a me Co.
ʻOi aku ka maikaʻi o ka YG ʻano o ka cemented carbide bending ikaika a me ka paʻakikī paʻakikī, kūpono no ka hana brittle material, hiki ke hoʻohana ʻia no ka hao hao, nā metala non-ferrous a me kā lākou mau mea hoʻoheheʻe a me nā mea hana ʻole. ʻoluʻolu, e emi ana kona paʻakikī, ʻoiai ka piʻi ʻana o ka ikaika kulou, ka hiki ke kū i ka hopena o ka hoʻonui ʻana i ka roughing, kūpono no ka mīkini paʻakikī.ʻO ka mea'ē aʻe, hoʻonui ka paʻakikī, keʻaʻahu a me ka pale wela, kūpono no ka hoʻopauʻana.
Ua like ka papa P me ka tungsten, cobalt a me ka titanium cemented carbide o Kina, ka inoa inoa YT, kona hui pū ʻana me WC a me Co, akā aia pū kekahi 5% ~ 30% o TiC, no ka mea, ʻoi aku ka paʻakikī a me ka heheʻe o TiC ma mua o WC. , no laila, ʻoi aku ka kiʻekiʻe o ka paʻakikī, ke kūpaʻa a me ka pale wela o ia mau carbide cemented ma mua o ka papa YG, a ʻoi aku ka haʻahaʻa o ka ikaika kulou a me ka paʻakikī.Me ka hoʻonui ʻana o ka ʻike TiC, ʻoi aku ka maikaʻi o ka paʻakikī, ka pale ʻana i ka wela a me ke kūpaʻa ʻana o ka mea, ʻoiai ke emi nei ka ikaika kulou a me ka paʻakikī.
Hiki ke hoʻohana maʻamau ke ʻano YT o ka carbide cemented no ka ʻoki kila kiʻekiʻe.
ʻO ka papa M ua like ia me ka tungsten-titanium-tantalum (niobium) cobalt cemented carbide o Kina, codenamed YW class, i hoʻohui ʻia i kekahi maʻiʻo o TaC a i ʻole NbC i ke ʻano o ka carbide i hoʻopaʻa ʻia ma luna i mea e hoʻomaikaʻi ai i ka paʻakikī kiʻekiʻe. kiʻekiʻe-mehana ikaika a me ka abrasion kū'ē o ka cemented carbide mea.
Hōʻike ʻia ka papa YW e: maikaʻi ka hana holoʻokoʻa, ākea ka nui o nā noi, hiki ke hoʻohana ʻia no nā ʻano o ka hao hao, ke kila, ke kila kila a me ka hoʻoili ʻana i ka wela wela.
Me ka hoʻomau mau ʻana o nā ʻano carbide cemented ultra-fine grain a me nā mea carbide cemented i uhi ʻia, ua hoʻomaikaʻi maikaʻi ʻia ka hana o nā mea carbide cemented, a ua hoʻomaikaʻi maikaʻi ʻia ka ikaika flexural, ka paʻakikī a me ke kūpaʻa ʻana o ka carbide cemented, a me ka carbide cemented. ua hoʻomaka hoʻi e hoʻohana ʻia i nā mea nui ma ke kahua o nā mea hana ʻoki paʻakikī, e like me nā drills, reamers, taps, mill cutters, hobs, a broaches, etc. .
Hoʻopuka nui kā mākou hui i ka Carbide Rotary File, Carbide rods, Carbide Scraper Blade, Carbide Corrugated Slitter Knife, Carbide Woodworking Replaceable Blade a me nā huahana Cemented Carbide.
