Nā wahi noi a me nā koi o nā brick alumina kiʻekiʻe ma nā kapuahi wela wela

ʻO ka umu wela wela ka umu hoʻoheheʻe ʻana i ka ironmaking he kumu nui i ka hana hao. ʻO nā pōhaku lepo alumina kiʻekiʻe, ʻo ia ka huahana kumu o nā mea refractory, hoʻohana nui ʻia i nā umu wela wela. Ma muli o ka nui o ka ʻokoʻa wela ma waena o nā ʻāpana o luna a me lalo o ka umu wela wela, ʻokoʻa loa nā mea refractory i hoʻohana ʻia i kēlā me kēia ʻāpana. ʻO nā wahi nui kahi e hoʻohana ʻia ai nā pōhaku alumina kiʻekiʻe, ʻo ia nā wahi o ka umu ahi wela, nā pā nui, nā regenerators, nā keʻena puhi ahi, a me nā kikoʻī penei:

1. Dome

ʻO ka vault ka wahi e hoʻopili ai i ke keʻena puhi ahi a me ka regenerator, me ka papa hana o nā pōhaku lepo, ka papa hoʻopiha a me ka papa insulation. No ka mea, ʻoi aku ka kiʻekiʻe o ka mahana o ka lua ahi wela, ʻoi aku ma mua o 1400, ʻo nā pōhaku alumina kiʻekiʻe i hoʻohana ʻia i ka papa hana he mau pōhaku alumina kiʻekiʻe. Hiki ke hoʻohana ʻia nā pōhaku silica, nā pōhaku mullite, nā sillimanite, a me nā pōhaku ʻulaʻula ma kēia wahi. ;

2. Pa nui

ʻO ka pā nui o ka umu wela wela e pili ana i ka ʻāpana pā a puni o ke kino wela wela, me ka papa hana o nā pōhaku lepo, ka papa hoʻopiha a me ka papa insulation. Hoʻohana nā pōhaku lepo hana i nā pōhaku ʻokoʻa refractory e like me nā mahana like ʻole ma luna a ma lalo. Hoʻohana nui ʻia nā pōhaku alumina kiʻekiʻe ma waena a me lalo.

3. Mea hana hou

ʻO ka regenerator kahi wahi i hoʻopiha ʻia me nā pōhaku lepo. ʻO kāna hana nui, ʻo ia ka hoʻohana ʻana i nā brick checker kūloko e hoʻololi i ka wela me ke kinoea flue wela kiʻekiʻe a me ka ea puhi. Ma kēia ʻāpana, hoʻohana ʻia nā pōhaku alumina kiʻekiʻe haʻahaʻa, ma ke kūlana waena.

4. Keena kuni

ʻO ke keʻena kuni ka wahi e puhi ʻia ai ke kinoea. ʻO ka hoʻonohonoho ʻana o ke keʻena ahi he pilina nui me ke ʻano o ka umu ahi a me ke ʻano o ka umu wela wela. Hoʻohana nui ʻia nā pōhaku alumina kiʻekiʻe ma kēia wahi. Hoʻohana ʻia nā pōhaku lepo alumina kiʻekiʻe kiʻekiʻe ma nā wahi wela, a hiki ke hoʻohana ʻia nā pōhaku alumina kiʻekiʻe maʻamau i nā wahi wela a me nā wahi haʻahaʻa.
