ʻO ke koʻokoʻo tungsten carbide ka pahu pōʻai tungsten, i ʻike ʻia ʻo tungsten steel bar, maʻalahi e ʻōlelo, tungsten steel round bar a i ʻole tungsten carbide round bar.ʻO Tungsten carbide kahi mea i hana ʻia e ka pauka metallurgy a i haku ʻia me nā pūhui metala refractory (paʻakikī paʻakikī) a me nā metala paʻa (binder phase).
ʻElua mau ala hana no ka hana ʻana i nā kaola pōʻai tungsten carbide: hoʻokahi ka extrusion, a ʻo ka extrusion kahi ala kūpono e hana ai i nā kī lōʻihi.Hiki ke ʻoki ʻia i kekahi lōʻihi i makemake ʻia e ka mea hoʻohana i ke kaʻina extrusion.Eia naʻe, ʻaʻole hiki i ka lōʻihi holoʻokoʻa ma mua o 350mm.ʻO ka mea ʻē aʻe ʻo ka hoʻoheheʻe ʻia ʻana, ʻo ia ke ala kūpono e hana ai i kahi pahu pahu pōkole.E like me ka inoa i hōʻike ʻia, ua kaomi ʻia ka pauka carbide cemented i ke ʻano me kahi ʻano.
ʻO ka carbide Cemented he moʻo o nā waiwai maikaʻi loa e like me ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻana, ka ikaika maikaʻi a me ka paʻakikī, ke kūpaʻa wela, ka pale ʻana i ka corrosion, ʻoi aku ka paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana, ʻaʻole i hoʻololi ʻia ma kahi mahana o 500 °C, a mau nō. he paʻakikī kiʻekiʻe ma 1000 °C.Hoʻohana nui ʻia ʻo Tungsten carbide e like me nā mea hana, e like me ka hoʻohuli ʻana i nā mea hana, nā mea ʻoki wili, nā mea ʻoki planer, nā drills, nā ʻoki ʻokiʻoki, a me nā mea ʻē aʻe, no ka ʻoki ʻana i ka hao, nā metala non-ferrous, plastics, fibers kemikal, graphite, aniani, pōhaku a me nā mea maʻamau. kila, a hiki ke hoʻohana ʻia e ʻoki i ke kila wela, ke kila kila, ke kila manganese kiʻekiʻe, ke kila mea paʻahana a me nā mea paʻakikī ʻē aʻe e wili ai i ka pulu (mill pōpō, keena hoʻomaloʻo, Z-mixer, granulator---), kaomi (me ka ʻaoʻao). kaomi hydraulic press a extruder), --- sintering (degreasing furnace, integrated furnace a i ʻole HIP low pressure furnace).
ʻO nā mea maka he wili pulu, hoʻomaloʻo, doping glue, a laila hoʻomaloʻo a hoʻohaʻahaʻa i ke kaumaha ma hope o ka hoʻoheheʻe ʻana a i ʻole extrusion, a i ka hope loa e hana ʻia ai ka pāhaʻi hope loa ma ka debinding a me ka sintering.
ʻO ka hemahema o ka hana hoʻopuka ʻana o ka bar extrusion ʻo ia ka lōʻihi o ke kaʻina hana.ʻO ka ʻomi ʻana i nā kaola pōʻai liʻiliʻi ma lalo o 3mm a me ka haki ʻana i nā ʻaoʻao ʻelua e hoʻopau i kekahi mau mea.ʻO ka lōʻihi ka lōʻihi o ka carbide anawaena liʻiliʻi poʻe pahu, ʻoi aku ka hewa o ka pololei o ka blank.ʻOiaʻiʻo, hiki ke hoʻomaikaʻi ʻia nā pilikia pololei a me ka pōʻai e ka wili cylindrical i kahi pae hope.
ʻO kekahi, ʻo ia ka hoʻoheheʻe ʻia ʻana, ʻo ia ke ʻano o ka hana ʻana o ka pahu pahu pōkole.E like me ka inoa i hōʻike ʻia, ʻo ia ka ʻōpala e kaomi i ka pauka carbide cemented i ke ʻano.ʻO ka maikaʻi o kēia ʻano hana hana carbide bar ʻo ia ke hana ʻia i hoʻokahi pass a hōʻemi i ka ʻōpala.E hoʻomaʻamaʻa i ke kaʻina ʻoki uea a hoʻopau i ka pōʻai mea maloʻo o ke ʻano extrusion.Hiki i ka manawa pōkole i luna ke mālama i nā mea kūʻai aku 7-10 lā.
ʻO ka ʻōlelo koʻikoʻi, pili pū ka paʻi isostatic i ka hoʻoheheʻe ʻana.ʻO ka paʻi Isostatic ke ʻano hana kūpono no ka hana ʻana i nā pahu pōʻai tungsten carbide nui a lōʻihi.Ma o nā sila piston luna a me lalo, hoʻokomo ka paila kaomi i ka wai wai ma waena o ka cylinder kiʻekiʻe a me ka pahu kaomi, a hoʻouna ʻia ke kaomi ma o ka pahu kaomi e hana i ka pauka carbide cemented i kaomi ʻia.
