Wahi a nā kumuwaiwai ʻoihana, ka mākeke honua no kila kiʻekiʻe wikiwiki (HSS) e ulu ana nā mea hana ʻoki a ʻoi aku ma mua o $ 10 biliona e 2020. ʻO Jackie Wang-General manakia o Shanghai Histar Metal, ke nānā nei i ke kumu e noho mau ai ka HSS i kahi koho kaulana, nā ʻano haku mele ʻokoʻa i loaʻa a me ka hoʻopili ʻana o nā mea i kahi ʻoihana wikiwiki.

ʻOiai ka hoʻokūkū e ulu nei mai ka carbide paʻa, hoʻomau ʻia ka makemake o ka HSS me nā mea hana ma muli o ke kūpaʻa o ke kiʻekiʻe a me nā ʻoʻoleʻa maikaʻi a me nā ʻoʻoleʻa. ʻOi aku ka maikaʻi o nā pono hana ʻoki HSS i nā wahi hana nui kahi e ola ai ka mea hana, maʻalahi, hana a me nā kumukūʻai mea hana ke koʻikoʻi nui i ka mea hoʻohana hope. No laila ke pāʻani nei kekahi ʻāpana nui i ka mīkini pono a me ka hilinaʻi o nā mea he nui.

Eia nō naʻe, ke nānā aku nei i kēia manawa no kahi huahana huahana maikaʻi, e kū ana i nā koina noi o nā mea kūʻai aku ma ke kumu kūʻai kumukūʻai, ke hōʻike maikaʻi ʻia nei i kēia ʻano hoʻokele waiwai o ka honua.

I mea e kākoʻo ai i ka ulu nui ʻana o ka noi no HSS, ʻO ka hana ʻana i nā mea hana hana hana i hana nui i kēia ʻāpana. Hoʻopili pū kēia me ka hoʻonui ʻana i ka hoʻopukapuka ʻaʻole wale ma ka hoʻomohala huahana hou akā ʻo ka noiʻi a me nā hana hoʻomohala, i alakaʻi ʻia i nā mea hana HSS e ʻoi aku ka hilinaʻi me ka hōʻemi ʻana i nā helu o nā hemahema, nā kumukūʻai hana haʻahaʻa a me nā manawa alakaʻi pōkole. ʻO ka hoʻohui ʻana o nā substrates i hoʻomaikaʻi ʻia, me ka metallurgy pauma a me ka uhi ʻana he mea kōkua i ka hoʻonui ʻana i ka hana.

Hāʻawi ʻo Shanghai Histar Metal pepa wikiwiki kiʻekiʻe, ʻaukā puni a me ka pā pālahalaha. Hoʻohana ʻia kēia mau mea no ka drills, countersinks, reamers, taps and milling cutters.

Hoʻohui HSS

ʻO kahi hiʻohiʻona HSS maʻamau hiʻohiʻona chromium (4%), tungsten (approx. 6%), molybdenum (a i 10%), vanadium (ma kahi o 2%), cobalt (a i 9%) a me carbon (1%). Pili nā ʻano papa like ʻole i nā pae ʻokoʻa o nā mea i hoʻohui ʻia.

Hoʻomaikaʻi ʻo Chromium i ka hiki ke paʻakikī a pale i ka hoʻonui ʻana. Hāʻawi ʻo Tungsten i ka ʻoki ʻana i ʻoi aku ka maikaʻi a me ke kūpaʻa i ka hoʻonāukiuki, a me ka hoʻomaikaʻi ʻana i ka paʻakikī a me ka ikaika o ka wela kiʻekiʻe. ʻO Molybdenum - kahi huahana o ke keleawe a me ka hana tungsten - hoʻomaikaʻi pū kekahi i ka maikaʻi o ka ʻoki ʻana a me ka paʻakikī, a me ke kūʻē ʻana i ka hoʻonāukiuki. ʻO Vanadium, aia i loko o nā minelala he nui, hana i nā karbida paʻakikī loa no ke kū pono o ka pale abrasive maikaʻi, hoʻonui i ke kū ʻana o ka wela kiʻekiʻe a me ka ikaika, a me ka paʻa o ka paʻakikī.

Hoʻonui ka Cobalt i ke kūpaʻa ʻana o ka wela, ka paʻa ʻana o ka paʻakikī a hoʻomaikaʻi iki i ka conductivity wela, ʻoiai ʻo carbon, hoʻonui i ka pale lole a he kuleana no ka paʻakikī paʻakikī (ma kahi o 62-65 Rc). ʻO ka hoʻohui o 5-8% ʻoi aku ka nui o ka cobalt i ka HSS e hoʻomaikaʻi i ka ikaika a ʻaʻa i ke kūpaʻa. ʻO ka maʻamau, hoʻohana ʻia nā drills me ka hoʻohui o nā cobalt hou aʻe i nā hana kikoʻī noi.

Nā mea maikaʻi

Hiki i nā pono HSS ke pale aku i nā haʻalulu, ke ʻano o ka meahana mīkini, ʻoiai inā ua nalo ka ʻoʻoleʻa i ka manawa a me ka nānā ʻole i nā ʻano o ka hoʻopaʻa ʻana i ka ʻāpana hana. Hiki iā ia ke pale i nā haʻalulu mīkini ma ka pae niho i nā hana wili a kū i nā ʻano lubrication loli e hopena ai i nā loli wela.

Eia nō naʻe, mahalo i ka ikaika kūlohelohe o HSS, hiki i nā mea hana hana hana ke hana i nā kihi ʻoki loa loa. ʻOi aku ka maʻalahi o kēia i ka mīkini paʻakikī, hāʻawi i ka hana ʻoi aku ka paʻakikī o nā steels stainless austenitic a me nā mea kinikini, a hāʻawi i kahi maikaʻi o ka ʻilikai a me nā ʻae ʻana o nā ʻāpana mīkini.

Ke ʻoki ʻia ka hao a weluwelu ʻole, hāʻawi ia i ke ola o nā mea ʻoi aku ka lōʻihi me nā mahana o ke ana o lalo. Koi pū ʻia ia i nā mana ʻoki haʻahaʻa, ʻo ia ka mea i emi ai ka liʻiliʻi o ka mana mai ka mīkini mīkini. Mai kahi manaʻo ola mea hana, hana maikaʻi ʻo HSS me nā noi ʻoki intermittent.

Hōʻuluʻulu Manaʻo

I ka makahiki kahi e makemake ai nā mea hoʻohana i nā pono pono paʻa, kūlike ʻole i ka uku kumukūʻai, kila kiʻekiʻe Aia nō ke koho kūpono no nā noi he nui. E like me ia, hiki iā ia ke hoʻopaʻa i kāna pono ponoʻī i ka mākeke e kūʻē i nā mea ʻōpio a ʻoi aku hoʻi o ka ʻenehana.

Inā he mea, HSS ua lilo i mau makahiki i lilo i ikaika ma o ka hoʻololi ʻana iā ia iho me nā uhi hou, e hoʻoponopono ana i kāna ʻano a me ka hoʻohui ʻana i nā ʻenehana hou, ke kōkua nei nā mea āpau e hoʻopaʻa i kona kūlana ma ke ʻano he mea waiwai i ka ʻoihana ʻoki hao.

ʻO ka ʻāpana ʻenehana mea hana ʻokiʻoki kahi ʻāina hoʻokūkū a mau HSS ke waiho nei he kī nui i ka hāʻawi ʻana aku i nā mea kūʻai aku i nā mea e pono ai i nā manawa āpau: koho maikaʻi.
