He aha ke kila kalapona kiʻekiʻe?

ʻO ke kila kalapona kiʻekiʻe (High Carbon Steel) i ʻike maʻamau ʻia ʻo ka mea kila kila, ʻona ʻona mai ka 0.60% a i ka 1.70% , hoʻopiʻi a hoʻoulu.Hana ʻia nā hāmare a me nā crowbars i 0.75% carbon steel;ʻO nā mea hana ʻoki e like me nā drills, taps a me reamers i hana ʻia me 0.90% a 1.00% carbon steel.
ʻO ka ʻili o ka uea kila galvanized he maʻalahi, maʻemaʻe, ʻaʻohe māwae, nā hono, prickles, scars and rust.ʻO ka papa galvanized he ʻano like, hoʻopili ikaika, kūpaʻa kūpaʻa kūpaʻa, ʻoi aku ka paʻakikī a me ka elasticity.

ʻO ka paʻakikī a me ka ikaika o ke kila kalapona kiʻekiʻe e hilinaʻi nui i ka nui o ke kalapona i ka hopena, a hoʻonui me ka nui o ke kalapona i ka hopena.Ke ʻoi aku ka nui o ke kalapona ma mua o 0.6%, ʻaʻole e piʻi ka paʻakikī, akā hoʻonui ka nui o ka carbide nui, piʻi iki ka pale ʻana o ke kila, a emi ka plasticity, toughness a me ka elasticity.

I kēia hopena, pinepine e like me nā kūlana o ka hoʻohana ʻana a me ka ikaika o ke kila, paʻakikī e hoʻohālikelike e koho i nā kila like ʻole.No ka laʻana, no ka hana ʻana i kahi ʻāpana puna a i ʻole ʻano puna me ka ikaika liʻiliʻi, e koho i ka 65 # kila kalapona kiʻekiʻe me ka haʻahaʻa.Hiki ke hoʻohana ʻia ke kila kalapona kiʻekiʻe maʻamau i ka umu uila, ka kapuahi hāmama, ka hana hoʻololi oxygen.Hiki ke hoʻohana ʻia ka ʻoi aku ka maikaʻi a i ʻole nā ​​koi koʻikoʻi kūikawā no ka hoʻoheheʻe ʻana i ka umu uila me ka hoʻohana ʻana a i ʻole ka uila, slag remelting.

I ka ho'ohehe'e 'ana, ua ho'omalu pono 'ia ka haku mele 'ana, 'oi aku ka nui o ka sulfur a me ka phosphorus.I mea e hōʻemi ai i ka hoʻokaʻawale ʻana a me ka hoʻomaikaʻi ʻana i ka waiwai isotropic, hiki ke kau ʻia ka ingot i ke kiʻekiʻe kiʻekiʻe diffusion annealing (ʻoi aku ka mea nui no ka mea kila).I ka hana wela, pono ke haʻahaʻa (ma kahi o 800 ° C) ka wela o ka hoʻokuʻu ʻana (rolling) o ke kila hypereutectoid.Ma hope o ka forging a me ka ʻōwili ʻana, pono e pale ʻia ka ua o ka carbide network coarse.Kāohi i ka decarburization o ka ʻili i ka wā o ka mālama ʻana i ka wela a i ʻole ka hana wela (ʻoi aku ka nui o ke kila puna).I ka wā o ka hana wela, pono e lawa ka lakio kaomi e hōʻoia i ka maikaʻi a me ka hana lawelawe o ke kila.
