No Tungsten-Cobalt Cemented Carbide

Ma ke ʻano he ʻelele maʻamau o ka carbide cemented maʻamau, ʻo tungsten cobalt cemented carbide (YG type of cemented carbide) e pili ana i ka alloy i haku ʻia me ka carbide tungsten ma ke ʻano paʻakikī a me ka cobalt e like me ke ʻano cemented, ka inoa Pelekane ʻo tungsten cobalt cemented carbide, a ʻO ka inoa inoa i haku ʻia me YG a me ka pākēneka o ka ʻike cobalt maʻamau.ʻO ka inoa inoa ʻo "YG" a me ka pākēneka o ka ʻike cobalt maʻamau, e like me YG6, YG8 a pēlā aku.

Ma ke ʻano o ka hana, YG cemented carbide e hui pū i nā pono o ka tungsten carbide a me ka cobalt, ka mea i hōʻike nui ʻia i ka paʻakikī kiʻekiʻe, ka conductivity thermal maikaʻi, ka paʻakikī hopena maikaʻi, ka ikaika flexural kiʻekiʻe a me ke kūpaʻa ʻoki maikaʻi.Eia nō naʻe, pono e hoʻomaopopo ʻia he ʻokoʻa nā helu kino o nā māka like ʻole o ka YG cemented carbide, e like me ka density o YG6 he 14.6 ~ 15.0g / cm3, paʻakikī 89.5HRA, ikaika flexural 1400MPa, paʻakikī hopena 2.6J / cm2, coercivity 9.6 ~ 12.8KA / m, ikaika compressive 4600MPa;ʻo ka nui o YG8 he 14.5 ~ 14.9g / cm3;ʻo ka nui o YG8 he 14.5 ~ 14.9g / cm3;a ʻo ka mānoanoa o YG8 he 14.5 ~ 14.9g/cm3.ʻO ka YG8 ka nui o 14.5 ~ 14.9g / cm3, ka paʻakikī o 89HRA, ka ikaika flexural o 1500MPa, ka ikaika o ka hopena o 2.5J / cm2, ka coercivity o 11.2 ~ 12.8KA / m, a me ka ikaika compressive o 4600MPa.Ma keʻano laulā, me ka hoʻonui ʻana o ka ʻike cobalt i kekahi kūlana, ʻoi aku ka maikaʻi o ka flexural a me ka compressive ikaika a me ka paʻakikī o ka alloy, ʻoiai ka haʻahaʻa a me ka paʻakikī.

ʻO ke kūpaʻa a me ka paʻakikī o ka YG type cemented carbide maʻamau he mau kino kūʻē, i hōʻike nui ʻia i kēia mau mea: ma lalo o kekahi mau kūlana, me ka hoʻonui ʻana o ka ʻike cobalt a i ʻole ka emi ʻana o ka ʻike tungsten, ʻo ka paʻakikī o ka alloy. ʻoi aku ka maikaʻi a ʻoi aku ka maikaʻi o ka pale ʻana;ʻO ka mea ʻē aʻe, me ka hoʻonui ʻana o ka ʻike tungsten a i ʻole ka emi ʻana o ka ʻike cobalt, ʻoi aku ka maikaʻi o ka waiwai abrasive o ka alloy a ʻoi aku ka ʻilihune.I mea e hoʻoponopono ai i ka pilikia o ke kū'ē kū'ē a me ka paʻakikī o ka YG-type cemented carbide, ua hāʻawi ka mea noiʻi o Patent No. CN1234894C i kahi hana hana hou, nā mea maikaʻi o kēia ʻenehana hana: 1) Ma muli o ke ʻano like ʻole. ʻO nā kīʻaha WC, ua hoʻomaikaʻi ʻia ka hui ʻana o ka carbide cemented (ua hoʻemi ʻia ka pili ʻana o ka palaoa WC, ʻoi aku ka like o ka mahele o ka co-phase, hoʻemi ʻia ka porosity, a ua hoʻemi nui ʻia nā kumu māwae), no laila ʻoi aku ka maikaʻi o ke kūpaʻa a me ka paʻakikī o kēia alloy. nā ʻāpana like ʻole o ka cobalt coarser grained;2) ʻOi aku ka maikaʻi o ka hoʻohana ʻana i nā pauka cobalt maikaʻi ma mua o ka hoʻohana ʻana i nā pauka cobalt maʻamau (2-3μm), a ua hoʻonui ʻia ka paʻakikī o kēia huila e 5 a 10%, aʻo ka hoʻohui ʻana o (0.3-0.6wt%) TaC piʻi. ʻO kona paʻakikī (HRA) ma ka 0.2 a 0.3, ʻo ia hoʻi ua hoʻonui ʻia kona pale ʻana.~ 10%, a ma hope o ka hoʻohui ʻana (0.3-0.6wt%) TaC, hoʻonui ʻia kona paʻakikī (HRA) e 0.2-0.3, ʻo ia hoʻi, hoʻonui ʻia kona pale ʻana.

Mai ka manaʻo o nā ʻano, e like me ka ʻokoʻa cobalt ʻokoʻa, hiki ke hoʻokaʻawale ʻia ka tungsten-cobalt cemented carbide i nā haʻahaʻa-cobalt, medium-cobalt a me high-cobalt alloys;e like me nā ʻano hua like ʻole o ka tungsten carbide, hiki ke hoʻokaʻawale ʻia i nā micro-grain, fine-grain, medium-grain and coarse-grain alloys;e like me nā hoʻohana like ʻole, hiki ke hoʻokaʻawale ʻia i nā mea ʻokiʻoki, nā mea hana mining a me nā mea paʻa paʻa.

Mai ka hiʻohiʻona o ke kaʻina hana, ʻo nā ʻanuʻu hoʻomākaukau o ka YG cemented carbide e loaʻa i ka pauka tungsten carbide a me ka pauka cobalt ma o ka batching, wili pulu, maloʻo, granulation, kaomi a me ka hana ʻana, de-forming agent, sintering a pēlā aku.Nānā: Hoʻohana ʻia nā ʻano ʻāpana ʻelua a me nā ʻāpana maikaʻi o ka pauka WC no ka hoʻopaʻa ʻana, kahi o ka nui o ka pauka WC koʻikoʻi ʻo (20-30) μm, a ʻo ka nui o ka pauka WC ʻāpana maikaʻi (1.2-1.8) μm.

Mai ka ʻaoʻao o ka noi, hiki ke hoʻohana ʻia ka tungsten a me ka cobalt cemented carbide e ʻoki i ka hao, nā metala non-ferrous a me nā mea non-metallic, ma kahi o ka hana ʻana i nā mea hana lihi, nā kiʻi kiʻi kiʻi, nā pahu kuʻi anu, nā nozzles, nā ʻōwili, nā hāmare kiʻekiʻe a me nā mea hana ʻaʻahu a me nā mea hana eli.
