Pilikia Sillimanite no na kapuahi aniani

ʻO ka pōhaku Sillimanite kahi ʻano o ka pōhaku refractory i haku mua ʻia me ka mineral sillimanite (Al2SiO5). ʻIke ʻia ʻo ia no kona kūpaʻa kiʻekiʻe i ka haʻalulu wela, ke kūpaʻa kiʻekiʻe o ka mahana, a me ka inertness kemika, kūpono ia no ka hoʻohana ʻana i nā kaʻina hana ʻoihana kiʻekiʻe. Eia kekahi mau hiʻohiʻona nui a me ka hoʻohana ʻana i nā pōhaku lepo sillimanite:

Kāhea iā mā˚ou

nā kikoʻī huahana

Nā hiʻohiʻona

1. Kiʻekiʻe Refractoriness: Hiki i nā pōhaku lepo Sillimanite ke pale i nā mahana a hiki i 1650 ° C (3000 ° F).

2. Kū'ē Kū'ē Thermal: Kū'ē lākou i ka hoʻololi wikiwiki o ka mahana, kahi e pale ai i ka haki a me ka spalling.

3. Paʻa Paʻa Kemika: Paʻa kemika kēia mau pōhaku lepo a kūpaʻa i ka slag, acidic, a me nā kaiapuni kumu.

4. Ka ikaika o ka mīkini: Loaʻa iā lākou ka ikaika mechanical maikaʻi ma nā wela kiʻekiʻe.

5. Haʻahaʻa Thermal Expansion: Hoʻemi kēia i ka pōʻino o ke kino i ka wā o ka hoʻomehana a me ka hoʻoilo.

Huina

- Alumina (Al2O3): Ma kahi o 60-65%

- Silica (SiO2): Ma kahi o 30-35%

- Nā Minerale ʻē aʻe: ʻO ka nui liʻiliʻi o nā minerala ʻē aʻe a me nā pūhui e pili ana i ka hana kikoʻī a me ke kaʻina hana.

Nā noi

1. ʻOihana aniani:No ka uhi ʻana o ka umu ahi, ʻoi aku ka nui o ka superstructure a me nā wahi lei o nā kapuahi hoʻoheheʻe aniani.

2. ʻOihana Metallurgical:I ke kūkuluʻana i nā kapuahi wela wela a me nā kiln i hoʻohanaʻia no ka hana metala a me ka hoʻomaʻemaʻe.

3. ʻOihana Seramika:I loko o nā kilns a me nā mea hoʻoponopono wela kiʻekiʻe.

4. ʻOihana Kemika:No ka lining reactors a me nā moku wela kiʻekiʻe.

5. ʻOihana Sima:I nā kilns a me nā ʻōnaehana preheater kahi e koi ʻia ai ke kūpaʻa wela kiʻekiʻe.

Hana ʻana

ʻO ke kaʻina hana o nā pōhaku lepo sillimanite, ʻo ia ka ʻeli ʻana i ka mineral sillimanite, ka ʻoki ʻana a me ka wili ʻana iā ia i ka nui o ka mea i makemake ʻia, ka hui ʻana me nā mea hoʻopaʻa a me nā mea hoʻohui ʻē aʻe, e hoʻoheheʻe i ka hui ʻana i nā pōhaku lepo, a puhi iā lākou i loko o kahi kiln i nā wela kiʻekiʻe.

Nā pono

- Ka lōʻihi ma muli o ke kūpaʻa kiʻekiʻe i ka lole a me ka waimaka.

- ʻO ka ikaika o ka ikehu ma muli o ka haʻahaʻa haʻahaʻa haʻahaʻa.

- Hoʻemi ʻia nā kumukūʻai mālama ma muli o ka lōʻihi.

He mea koʻikoʻi nā pōhaku Sillimanite i nā ʻoihana e koi ana i nā mea hiki ke kū i nā kūlana koʻikoʻi, e hōʻoiaʻiʻo ana i ka pono o ka hana a me ka palekana.
