He aha ka tungsten carbide?

Ua ʻike ʻia ʻo Tungsten carbide, a i ʻole cemented carbide, i kapa ʻia ʻo ia he alloy hard, ʻo ia kekahi o nā mea paʻakikī loa.s i ka honua. ʻOiaʻiʻo, he metala, he hui puhana o tungsten, cobalt, a me kekahi mau metala e ae. ʻO ka carbide tungsten paʻakikī kiʻekiʻe loa i hana ʻia i kēia manawa ma kahi o 94 HRA, i ana ʻia e Rockwell A ala. ʻO kekahi o ka haku mele nui loas ʻO ka tungsten carbide ka tungsten, nona ka helu hoʻoheheʻe kiʻekiʻe ma waena o nā metala āpau. Hana ʻo Cobalt i mea hoʻopaʻa i kēia matrix metala a hoʻomaikaʻis ka ikaika kulou o ka tungsten carbide. Ma muli o ka hana kiʻekiʻe o ka tungsten carbide, he mea kūpono loa ia no nā ʻoihana he nui, e like me ka tungsten carbide inserts, carbide rods a me nā wili hope no nā mea hana ʻoki CNC; ʻoki ʻoki no ka ʻoki pepa, ʻoki pepa, a pēlā aku; make ke poʻomanaʻo tungsten carbide, make ke kui, make ke kaha kiʻi no ka noi pale ʻana; ʻO nā ʻōlelo aʻoaʻo ʻike tungsten carbide, nā pā carbide, nā ʻāpana carbide no ka ʻoki ʻana a me ka hoʻohana ʻana i ka noi; nā pihi tungsten carbide, HPGR studs, carbide mining inserts no nā māla wili. Hoʻohana nui ʻia nā mea tungsten carbide no laila ua kapa ʻia“nā niho no nā ʻoihana”.

He aha ke kaʻina hana no ka tungsten carbide?

1. ʻO ka hana mua i ka hana ʻana i kahi huahana tungsten carbide, ʻo ia ka hana ʻana i ka pauka. ʻO ka pauka ka hui ʻana o WC a me Cobalt, ua hui pū ʻia lākou i kekahi ratio. No ka laʻana, inā makemake nā mea kūʻai aku i ka tungsten carbide heading make, makemake i ka carbide grade YG20, ka nui 100 kilos. A laila e hui ka mea hana pauka a puni ka pauka Cobalt 18kgs me ka pauka 80kgs WC, ʻo ke koena o 2kgs nā pauka metala ʻē aʻe e hoʻohui ʻia e like me ka ʻoihana ʻoihana no ka papa YG20. E hoʻokomo ʻia nā pauka a pau i loko o nā mīkini wili. Aia nā mana like ʻole o nā mīkini wili, e like me 5kgs no nā laʻana, 25kgs, 50kgs, 100kgs, a i ʻole nā ​​mea nui aʻe.

2. Ma hope o ka hui ʻana o ka pauka, ʻo ka hana hou aʻe ka pulupulu a me ka maloʻo. Ma Zhuzhou Better Tungsten Carbide Company, hoʻohana ʻia kahi hale kiaʻi spray, e hoʻomaikaʻi i ka hana kino a me ke kemika o ka pauka tungsten carbide. ʻO ka pauka i hana ʻia me ka hale kiaʻi Spray ʻoi aku ka maikaʻi o ka hana ma mua o nā mīkini ʻē aʻe. Ma hope o ka pau ʻana o kēia kaʻina hana, komo ka pauda“mākaukau e paʻi” kūlana.

3. E kaomi ʻia ka pauda ma hope o ka“mākaukau e paʻi” hoʻāʻo ʻia ka pauda OK. Aia nā ʻano like ʻole o ke kaomi ʻana, a i ʻole mākou e ʻōlelo i nā ʻano hana like ʻole o nā huahana tungsten carbide. No ka laʻana, inā hana kahi hale hana i nā ʻōlelo aʻoaʻo tungsten carbide saw, e hoʻohana ʻia kahi mīkini paʻi kaʻa; inā makemake ʻia kahi tungsten carbide nui, e hoʻohana ʻia kahi mīkini paʻi hapa-manual. Aia kekahi mau ala ʻē aʻe e hana ai i nā huahana tungsten carbide, e like me ke kaomi isostatic anuanu (inoa pōkole ʻo CIP), a me nā mīkini extrusion.

4. ʻO ka Sintering ke kaʻina hana ma hope o ke kaomi ʻana, ʻo ia hoʻi ke kaʻina hana hope loa e hana ai i kahi metala tungsten carbide e hiki ke hoʻohana ʻia e like me ka paʻakikī kiʻekiʻe a me ka ikaika kiʻekiʻe ʻenekinia metala no ka ʻoki ʻana, ka pale ʻana i ka lole, ka wili, a i ʻole nā ​​noi ʻē aʻe. He kiʻekiʻe ka mahana o ka sintering i 1400 centigrade. No nā haku mele like ʻole, e ʻokoʻa ka mahana. I kēlā ʻano wela kiʻekiʻe, hiki i ka mea hoʻopili ke hoʻohui i ka pauka WC a hana i kahi ʻano ikaika. Hiki ke hana ʻia ke kaʻina hana sintering me kahi mīkini ʻea isostatic kiʻekiʻe (HIP).

ʻO ke kaʻina hana ma luna nei he wehewehe maʻalahi o ke kaʻina hana carbide cemented. ʻOiai he maʻalahi ke nānā aku, ʻo ka hana tungsten carbide kahi ʻoihana hōʻiliʻili kiʻekiʻe. ʻAʻole maʻalahi ka hana ʻana i nā huahana tungsten carbide kūpono. ʻO Tungsten kahi ʻano waiwai hiki ʻole ke hoʻololi ʻia, hoʻohana ʻia, ʻaʻole hiki ke hana hou i ka manawa pōkole. Mahalo i ka waiwai waiwai, e hōʻoia i kēlā me kēia pūʻulu o nā huahana tungsten carbide i kūpono ma mua o ka hiki ʻana i nā lima o nā mea kūʻai aku, ʻo ia kekahi o nā kumu nui e koi ai iā mākou e hana maikaʻi. E neʻe mau, e hoʻomaikaʻi mau!
