pwehewehe huahana

Hoʻokumu kā mākou hui i ka hao-chromium-aluminum a me ka nickel-chromium uila hoʻoheheʻe ʻia i nā uwea hoʻoheheʻe uila, e hoʻohana ana i ka mana uea umu i hoʻopaʻa ʻia e ka lolouila a ua ʻeha ʻia i ke ʻano e ka mīkini wili uila kiʻekiʻe. ʻO nā hiʻohiʻona o kēia huahana: ke kūpaʻa wela kiʻekiʻe, ka hoʻomehana wikiwiki, ka lōʻihi o ka lawelawe ʻana, ke kūpaʻa kūpaʻa, ka liʻiliʻi liʻiliʻi o ka mana, ka pitch like ʻole ma hope o ka hohola ʻana, ʻālohilohi a maʻemaʻe ka ʻili; hoʻohana nuiʻia i nā kapuahi uila liʻiliʻi, nā kapuahi muffle, nā mea hoʻomehana a me nā ea, nā umu likeʻole, nā paipu hoʻomehana uila a me nā mea hana hale, a me nā mea'ē aʻe.

ʻO ka mahana a me ka hui kemika o ka uea hoʻomehana

ʻO nā waiwai ʻenehana nui o ka uea alloy FeCrAl:

①He kiʻekiʻe ka mahana o ka hoʻohana ʻana, hiki ke piʻi i ka 1300 ℃ ka wela hoʻohana o ka uea alumini alumini hao-chromium i ka lewa;

②Lō lawelawe ola;

③ʻO ka haʻawe ili i ʻae ʻia he nui;

⑤ ʻOi aku ka liʻiliʻi o ka ʻumekaumaha ma mua o ka nickel-chromium alloy; ④Maikaʻi ka pale ʻana o ka oxidation, a ʻo ke kiʻi AI2O3 i hoʻokumu ʻia ma hope o ka oxidation he maikaʻi ke kūʻē kemika a me ka resistivity kiʻekiʻe;

⑥High resistivity;

⑦ ʻO ke kūpaʻa sulfur maikaʻi;

⑧ ʻOi aku ka haʻahaʻa o ke kumukūʻai ma mua o ka nickel-chromium alloy;

⑨ ʻO ka hemahema, ʻo ka piʻi ʻana o ka mahana, hōʻike ia i ka plasticity, a haʻahaʻa ka ikaika i nā wela kiʻekiʻe.

ʻO nā hiʻohiʻona o ka wili uila nickel-chromium:

① ʻO ka ikaika kiʻekiʻe i ka wela kiʻekiʻe;

②E hoʻomaha ma hope o ka hoʻohana lōʻihi, ʻaʻole e lilo ka mea i palupalu;

③ ʻOi aku ka kiʻekiʻe o ka emissivity o ka alloy Ni-ming i hoʻopaʻa piha ʻia ma mua o ka Fe-Cr-Al alloy;

④ʻAʻohe magnetism;

⑤Koe no ka lewa sulfur, ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion
