ʻO ka ʻokoʻa ma waena o ka paʻa paʻa a me ke kila māmā holo kiʻekiʻe

1. Nā hiʻohiʻona manaʻo

carbide simaʻO ia ka mea i hana ʻia me ka hui pū ʻana o ka carbide metala refractory e like me ka pauka tungsten carbide (WC) a me ka metala paʻa e like me ka pauka cobalt, i kapa ʻia ʻo Tungsten Carbide / Cemented Carbide ma ka ʻōlelo Pelekania, nona ka ʻike kiʻekiʻe o ka carbide kiʻekiʻe ma mua o ke kila kiʻekiʻe. .

ʻO ke kila wikiwiki kiʻekiʻe ka nui o ka tungsten, molybdenum, chromium, cobalt, vanadium a me nā mea ʻē aʻe o ke kila kila kila kiʻekiʻe, ka nui o ka carbide metala (e like me ka tungsten carbide, molybdenum carbide a i ʻole vanadium carbide) a me ke kila. matrix, ka maʻiʻo kalapona o 0.7% -1.65%, ka huina o nā mea hoʻohuihui a hiki i 10% -25%, ka inoa Pelekane o High Speed ​​Steels (HSS).

2, ka hana

Loaʻa i nā mea ʻelua ka paʻakikī nui, ka ikaika kiʻekiʻe, ka paʻakikī maikaʻi, ka ʻulaʻula-ʻulaʻula, ke kūpaʻa ʻana, ka pale ʻana i ka wela a me ka hana kaʻina hana, a me nā mea ʻē aʻe, a ʻokoʻa kēia mau hiʻohiʻona ma muli o nā pae like ʻole.ʻO ka mea maʻamau, ʻoi aku ka maikaʻi o ka paʻakikī, ka ʻulaʻula-ʻulaʻula, ke kūpaʻa a me ka pale wela o ka carbide cemented ma mua o ka HSS.

3, ka hana hana

ʻO ke kaʻina hana o ka carbide cemented ka mea nui e pili ana i ke kaʻina hana metallurgy pauka, ʻenehana hoʻoheheʻe injection a i ʻole ke kaʻina paʻi 3D.

ʻO nā ʻano hana hana o ke kila māmā e loaʻa i ka ʻenehana hoʻolei kuʻuna, ka ʻenehana electroslag remelting, ka ʻenehana metallurgy pauka a me ka ʻenehana molding injection.

4, noi

ʻOiai hiki i nā mea ʻelua ke hana i nā mea hana, nā mea hana wela a me nā ʻāpana hana anu, loaʻa iā lākou nā waiwai like ʻole.ʻO nā mea hana carbide maʻamau he 4 a 7 mau manawa ʻoi aku ka wikiwiki o ka ʻoki ʻana a me 5 a 80 mau manawa kiʻekiʻe o ke ola ma mua o nā mea hana HSS maʻamau.Ma ke ʻano o ka mea hana, ʻo ke ola o ka mea hana carbide he 20 a 150 mau manawa kiʻekiʻe ma mua o ka mea hana HSS, no ka laʻana, ke ola o ke poʻo wela a me ka extrusion make i hana ʻia me ke kila 3Cr2W8V he 0.5 miliona mau manawa, a ʻo ke ola o ke poʻo wela a me ka extrusion. ʻO ka make i hana ʻia me ka YG20 carbide he 150,000 mau manawa.
