ʻO ka Density o Tungsten Carbide

ʻO Tungsten Carbide, ka mea i kapa ʻia ʻo nā niho ʻoihana, kahi huahana maʻamau. He mea kaulana ia no kona mau waiwai maikaʻi e like me ka paʻakikī kiʻekiʻe, ka ikaika kiʻekiʻe, ke kiʻekiʻe kiʻekiʻe, ka pale ʻana i ka ʻaʻahu, a me ka pale ʻana i ka corrosion, no laila, hiki ke hana ʻia i loko o nā ʻāpana drill like ʻole, nā mea ʻoki, nā mea hana wili pōhaku, nā mea hana mining, nā ʻāpana lole, nā cylinder liners , a laila. I ka ʻoihana, e hoʻopili mākou i nā ʻāpana he nui e hoʻāʻo a hōʻoia i ka maikaʻi o nā huahana tungsten carbide. Ma kēia ʻatikala, e kamaʻilio ʻia ka hiʻohiʻona kino kino, density.

He aha ka mānoanoa?

ʻO ka Density kahi mea kikoʻī waiwai mechanical e hōʻike i ka nui o ka carbide cemented no kēlā me kēia leo. ʻO ka leo a mākou i ʻōlelo ai ma ʻaneʻi, aia ka nui o nā pores i loko o ka mea. Wahi a ka ʻōnaehana honua o nā ʻāpana a me nā ʻāpana ana kānāwai o Kina, ua hōʻike ʻia ka density e ka hōʻailona ρ, a ʻo ka ʻāpana o ka density he kg / m3.

ʻO ka nui o ka tungsten carbide

Ma lalo o ke kaʻina hana hana like a me nā ʻāpana like, e hoʻololi ʻia ka nui o ka carbide cemented me ka hoʻololi ʻana o ka haku melemele a i ʻole ka hoʻoponopono ʻana i ka ratio waiwai maka.

ʻO nā mea nui o ka YG series cemented carbide he tungsten carbide pauka a me ka pauka cobalt. Ma lalo o kekahi mau kūlana, e like me ka hoʻonui ʻana o ka cobalt content, e emi ana ka nui o ka alloy, akā i ka wā i loaʻa ai ka waiwai koʻikoʻi, liʻiliʻi ka laulā fluctuation density. ʻO ka mānoanoa o YG6 alloy he 14.5-14.9g/cm3, ʻo ka density o YG15 alloy he 13.9-14.2g/cm3, a ʻo ka density o YG20 alloy he 13.4-13.7g/cm3.

ʻO nā mea nui o ka YT series cemented carbide he tungsten carbide pauka, titanium carbide pauka, a me ka pauka cobalt. Ma lalo o kekahi mau kūlana, e like me ka piʻi ʻana o ka pauka titanium carbide, hoʻemi ka nui o ka alloy. YT5 puʻupuʻu puʻupuʻu 12.5-13.2g/cm3, YT14 puʻupuʻu puʻupuʻu 11.2-12.0g/cm3, YT15 puʻupuʻu puʻupuʻu 11.0-11.7g/cm3

ʻO nā mea nui o ka YW series cemented carbide he tungsten carbide pauka, titanium carbide pauka, tantalum carbide pauka, niobium carbide pauka, a me ka pauka cobalt. ʻO ka mānoanoa o YW1 alloy he 12.6-13.5g/cm3, ʻo ka mānoanoa o YW2 alloy he 12.4-13.5g/cm3, a ʻo ka mānoanoa o YW3 alloy he 12.4-13.3g/cm3.

Ma muli o kona kiʻekiʻe kiʻekiʻe, hiki ke hana ʻia ka carbide cemented i nā ʻano huahana like ʻole, e like me nā counterweights mechanical, nā koʻokoʻo paona i hoʻohana ʻia i nā ʻoihana wili e like me ka aila, nā pendulum uaki, nā ballast no ka holo ʻana, ka holo ʻana, a me nā mea ʻē aʻe. ,  hiki iā ia ke hōʻoia i ke koena o nā mea i loko o kahi kūlana hana a paʻa paha, a i ʻole mālama nui i ka hana o nā limahana.

Nā kumu o ka tungsten carbide density

Pili ka Density i ka haku mele, raw material ratio, microstructure, production process, process parameters, a me nā mea ʻē aʻe. ʻO ka ʻōlelo maʻamau, ʻokoʻa nō hoʻi nā kahua noi o nā carbide cemented me nā ʻano like ʻole. ʻO ka mea ma lalo nei ka mea nui e hoʻolauna i nā mea hoʻoikaika o ka paʻa paʻa.

1. Mea haku mele

Hiki ke hana ʻia ka carbide cemented i ʻelua pauka, ka pauka tungsten carbide (WC pauka) a me ka pauka cobalt (Co pauda), a i ʻole ʻekolu pauka: WC pauka, TiC pauka (titanium carbide pauka) a me Co pauka, a i ʻole WC pauka. ʻO ka pauka, ka pauka TiC, ka pauka TaC (ka pauka tantalum carbide), ka pauka NbC (ka pauka niobium), a me ka pauka Co. Ma muli o nā ʻano like ʻole o nā mea hoʻoheheʻe, ʻokoʻa ka nui o ka alloy, akā ua like nā ʻāpana: ʻo ka nui o ka YG6 alloy he 14.5-14.9g/cm³, ʻo ka nui o ka alloy YT5 he 12.5-13.2g/ cm³, a ʻo ka mānoanoa o ka huila YW1 he 12.6-13.5g/cm³.

Ma ka ʻōlelo maʻamau, piʻi ka nui o ka tungsten-cobalt (YG) cemented carbide me ka piʻi ʻana o ka ʻike o ka pauka WC. No ka laʻana, he 14.5-14.9g/cm³ ka mānoanoa o ka pāpaʻa me ka WC pauka maʻiʻo o 94% (YG6 alloy), a me ka WC pauka maʻiʻo ʻO ka nui o 85% alloy (YG15 alloy)he 13.9-14.2g/cm³.

Ke emi nei ka mānoanoa o nā tungsten-titanium-cobalt (YT) me ka hoʻonui ʻana o ka pauka TiC. No ka laʻana, ʻo 12.5-13.2g/cm³ ka nui o nā ʻāpana me ka TiC pauka maʻiʻo o 5% (YT5 alloy), a ʻo ka pauka TiC he 15%. ʻO ka mānoanoa o ka huila (YT15 alloy) he 11.0-11.7g/cm³.

2. Microstructure

Hoʻokumu ʻia ka porosity e nā pores a me ka shrinkage a he hōʻailona koʻikoʻi ia no ka hoʻoholo ʻana i ka maikaʻi o ka carbide cemented. ʻO nā kumu nui o ka hoʻokumu ʻana i nā pores cemented carbide ʻo ia hoʻi ka over-burning, nā mea hoʻopili organik, nā mea metala, nā waiwai kaomi maikaʻi ʻole, a me nā mea hoʻoheheʻe ʻole.

Ma muli o ka loaʻa ʻana o nā pores, ʻoi aku ka liʻiliʻi maoli o ka alloy ma mua o ka theoretical density. ʻO ka nui a ʻoi aku ka nui o nā pores, ʻoi aku ka liʻiliʻi o ka paona ma kahi paona i hāʻawi ʻia.

3. Kaʻina hana

Aia i loko o ke kaʻina hana kahi kaʻina hana metala pauka a me ka ʻenehana hoʻoheheʻe injection. ʻO nā hemahema e like me ka carburizing, under-burning, fouling, bubbling, peeling, and uncompacting during pressing and sintering e alakaʻi i ka emi ʻana o ka nui o ka carbide cemented.

4. Kaiapuni hana

ʻO ka mea maʻamau, me ka hoʻololi ʻana i ka mahana a i ʻole ke kaomi, e loli like ka leo a i ʻole ka nui o ka alloy, akā liʻiliʻi ka loli a hiki ke nānā ʻole ʻia.

Inā makemake ʻoe i nā huahana tungsten carbide a makemake ʻoe i ka ʻike hou aku a me nā kikoʻī, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou.
