ʻO ke ʻano hana o ka tungsten carbide

ʻO ka tungsten carbideHe hui ia me ka tungsten a me ke kalapona.Ua like kona paakiki me ke daimana.Paʻa loa kona mau waiwai kemika a kaulana loa ia ma nā ʻano ʻoihana like ʻole.I kēia lā, e kamaʻilio ʻo Sidi Xiaobian me ʻoe e pili ana i ke ʻano hana o ka tungsten carbide.

E like me nā koi otungsten carbide rollerka nui, hoʻohana ʻia nā ʻano like ʻole o ka tungsten carbide no nā kumu like ʻole.ʻO nā mea hana ʻoki karbide, e like me ka ʻoki mīkini ʻoki ʻana i nā mea hana V-like ʻoki ʻana, nā mea hoʻoheheʻe maikaʻi me ka ultrafine subfine tungsten carbide particles.Hoʻohana ʻia nā mea hoʻoheheʻe ʻia me ka tungsten carbide;ʻO ka alloy no ka ʻoki ʻana i ka gravity a me ka ʻoki kaumaha i hana ʻia me ka carbide tungsten coarse medium.ʻO ka pōhaku i hoʻohana ʻia no nā mea hana mining he paʻakikī kiʻekiʻe a me nā ukana hopena a hoʻohana i ka carbide tungsten koʻikoʻi.ʻO ka hopena pōhaku liʻiliʻi, ka ukana liʻiliʻi liʻiliʻi, me ka ʻāpana tungsten carbide ma ke ʻano he ʻāpana kūʻokoʻa i ka lole maka;I ka hoʻoikaika ʻana i ka pale ʻana i ka ʻaʻahu, ka pale ʻana i ke kaomi a me ka maʻalahi o ka ʻili, hoʻohana ʻia ka ultrafine ultrafine medium particle tungsten carbide e like me ka mea maka.Hoʻohana nui ʻia ka mea hana hopena i ka medium and coarse tungsten carbide raw material.

He 6.128% (50% atomic) ka tungsten carbide.Ke ʻoi aku ka nui o ke kalapona o ka tungsten carbide ma mua o ka ʻike kalapona theoretical, ʻike ʻia ke kalapona manuahi i ka tungsten carbide.ʻO ka loaʻa ʻana o ke kalapona manuahi e ulu nui ai nā ʻāpana tungsten carbide a puni i ka wā o ka sintering, ka hopena i nā ʻāpana carbide cemented ʻole.Pono ka tungsten carbide i ke kalapona paʻa kiʻekiʻe (≥6.07%) a me ke kalapona manuahi (≤0.05%), ʻoiai ka nui o ke kalapona e pili ana i ke kaʻina hana a me ka hoʻohana ʻana o ka carbide cemented.

Ma lalo o nā kūlana maʻamau, ʻo ka huina kalapona o ka vacuum sintering tungsten carbide ma ke ʻano paraffin e hoʻoholo nui ʻia e ka huina o ka oxygen o briquette ma mua o ka sintering.ʻO ka hapa o ka oxygen maʻiʻo i hoʻonui ʻia e 0.75 hapa, ʻo ia hoʻi, ka huina kalapona o tungsten carbide = 6.13%+ oxygen maʻiʻo % × 0.75 (manaʻo ʻia aia kahi ea kūʻokoʻa i ka umu sintering, ʻoiaʻiʻo, ʻo ka huina kalapona o tungsten carbide i loko. ʻO ka hapa nui o nā kapuahi haʻahaʻa ʻoi aku ka liʻiliʻi ma mua o ka helu helu) [4] Hiki ke hoʻokaʻawale ʻia ka huina kalapona o ka tungsten carbide Kina i ʻekolu kaʻina paraffin.

ʻO ka tungsten carbide i hoʻopaʻa ʻia i loko o ka vacuum he huina kalapona ma kahi o 6.18±0.03% (e piʻi ka kalapona manuahi).ʻO ka huina kalapona o ka paraffin wax hydrogen sintering tungsten carbide he 6.13±0.03%.ʻO ka huina kalapona o ka hydrogen sintering tungsten carbide he 5.90±0.03%.Hoʻololi kēia mau kaʻina hana i kekahi manawa.No laila, ua hoʻoholo ʻia ka huina kalapona o ka tungsten carbide e like me nā kūlana kikoʻī.
