ʻO ka hoʻopau ʻana a me ka hoʻomaʻamaʻa ʻana, ʻo ia ke kaʻina hana wela e hana mau ʻia ma ka pae hoʻopau hope o nā ʻāpana, e hoʻoholo i nā waiwai mechanical kiʻekiʻe.
JINDALAI lakoCold Worked, Hot Rolled and Forged Steels for Quenching and Tempering e hāʻawi ana i nā hāʻina hoʻolako maʻamau e pili ana i nā kikoʻī a me nā koi kikoʻī ʻē aʻe i mea e hoʻokō ai i ka pono o kēlā me kēia mea kūʻai aku ma ke ʻano o nā māka a me nā kiʻi. ʻO kā mākou hui, me kāna 10lālā-nā keʻenai lokoKinaa he 200 ka nui o ka puunaue makahiki,000 Tons, ʻo ia ka hoa kūpono e hoʻonui i kāu ʻoihana.
He aha ka Quench & Tempered Steel?
Loaʻa i nā kila a pau kekahi kalapona, ʻoi aku ka paʻakikī. Hiki i ka nui o ke kalapona ke hoʻonāwaliwali i ka pono o ke kila. Hoʻohana ʻia nā kaʻina hana kuʻi a me ka huhū e hoʻonui i nā ʻano mīkini o ke kila kalapona me ka ʻole o ka hoʻohui ʻana i nā kalapona.
ʻO ke kila kila kiʻekiʻe he 0.60 a 1.00% ka nui o ke kalapona i hoʻohālikelike ʻia me ka 0.05 a 0.25% o ke kila māmā. Ke hele nei ke kila kalapona kiʻekiʻe ma ke kaʻina kinai a me ka huhū, ʻoi aku ka maikaʻi o kona mau ʻano mechanical.
ʻO kēia kaʻina hana hoʻi e hōʻike i ka waihona metala i ka hoʻomaha wikiwiki (quenching) a me ka hoʻomehana hou ʻana me kahi kaʻina hoʻomaha mālie (tempering). ʻO nā kaʻina hana hoʻopiʻi a me ka hoʻoulu ʻana ke kuleana no ka hoʻohui ʻana i ka ikaika a me ka paʻakikī i ke kila.
Kaʻina hana For Quenching aTempering
I mea e hoʻoikaika ai i ka paʻakikī a me ka ikaika o ke kila, ua hoʻomohala ʻia kahi hana wela kūikawā, i kapa ʻia ʻo quenching and tempering. Hiki ke hoʻokaʻawale ʻia ʻo Quensching a me ka hoʻomaʻamaʻa ʻana i ʻekolu mau ʻanuʻu kumu:
Austenitizing → hoʻomehana i luna o ka laina GSK i loko o ka ʻāina austenite
Quenching → hoʻolili wikiwiki ma lalo o γγ-αα-transformation
Tempering → hoʻomehana hou i nā mahana haʻahaʻa me ka mālie mālie
