Pereki Silica Mullite: Te Otinga Tino Pai mō ngā Mahi Ahumahi Pāmahana-Tiketike

I te ao o ngā ahumahi pāmahana teitei, ko te kōwhiringa o ngā rauemi ātete ahi te mea e whakatau tika ana i te whai huatanga o te whakaputanga, te haumaru, me te whakahaere utu.Pereki Mullite Silica(e mōhiotia ana ko ngā Pereki Ātete-Hiko-Mullite) kua puta hei mea whakarerekē i te kēmu, nā te mea he tino pumau te pāmahana, he kaha teitei, he ātete pai ki te waikura. Ahakoa kei te whakahaere koe i te oumu sima, i te oumu karāhe, i te poiha ahumahi rānei, ka tukuna e ēnei pereki he mahi tino pai hei pupuri i te rere pai o āu mahi.​

1. He aha i tū motuhake ai ngā pereki silica mullite: Ngā painga matua​

I mua i te ruku hohonu ki ā rātou whakamahinga, me whakamāramahia ngā āhuatanga matua e tino hiahiatia ai ngā pereki silica mullite mō ngā taiao pāmahana teitei:
Ātete Ru Wera Pai Rawa:He iti te tauwehenga whānui wera, ā, ka taea e rātou te tu atu i ngā huringa pāmahana tere (mai i te wera nui ki te whakamatao) me te kore e pakaru—he mea nui mō ngā tukanga he maha ngā huringa wera.

Teitei o te Ātete:Ka mau tonu te hanganga pai i ngā pāmahana tae atu ki te 1750°C (3182°F), ā, he mea tino pai mō ngā ahumahi e mau tonu ana te wera nui.

Kaha Mīhini Tino Pai:Ahakoa i raro i ngā kawenga nui me te ahotea wera, ka ātete tonu rātou ki te whakarerekētanga, ka whakaiti i te hiahia mō ngā whakakapinga maha me te wā kore mahi.

Ātete ki te Waikura me te Horo:Ka tū pakari rātou ki ngā mea kaha pērā i te para rewa, te kawakore, me ngā hau waikawa—he mea noa i roto i te hanga sima, maitai, me te karāhe.

Te Arahi Wera Iti:Ka āwhina ki te pupuri i te wera i roto i ngā oumu, ka whakapai ake i te whai huatanga o te pūngao me te whakaiti i ngā utu wahie.

2. Ngā Whakamahinga Matua: Ngā Wāhi e Hiranga ai ngā Pereki Silica Mullite

He maha ngā whakamahinga o ngā pereki silica mullite, ā, he mea hanga kia tutuki ai ngā hiahia ahurei o ngā ahumahi pāmahana teitei. Kei raro nei ngā whakamahinga tino whai hua:

2.1 Ahumahi Sima: Te Whakakaha i ngā Oihu me ngā Rohe Whakapūngao​

Ko te tukanga hanga sima e whakawhirinaki ana ki te wera nui tonu—ina koa i roto i ngā oumu hurihuri me ngā rohe whakapūkara. Ko ngā pereki silica mullite te whiringa matua i konei nā te mea:

Ka ātete rātou i te wera nui (1400–1600°C) me te ahotea ā-pūkaha o ngā oumu hurihuri, i te wā e pakaru wawe ai, e memeha rānei ētahi atu pereki.

Mā te ātete ki te whakaekenga kawakore (mai i te sima clinker) ka ārai i te pirau o ngā pereki, ka roa ake te ora o te oumu, ka whakaiti hoki i ngā utu tiaki.

Whakamahinga Take:Ka whakamahia e ngā wheketere sima nui o te ao ngā pereki silica mullite i roto i te rohe tahunga me te rohe whakawhiti o ngā oumu hurihuri, ka whakaiti i te wā kore mahi mā te 30% i te toharite.

2.2 Ahumahi Karāhe: Te Whakarite i te Hanganga Mārama, Pūmau

Ka mahi ngā oumu karāhe i ngā pāmahana neke atu i te 1600°C, ā, ko te karāhe rewa me ngā hau pūngāwerewere he tūmomo mōrearea tonu ki ngā rauemi ātete ahi. Ka whakatauhia ēnei wero e ngā pereki silica mullite:

Ka ātete rātou i te waikura mai i te karāhe rewa me ngā waikura boron (he mea noa i roto i te hanga karāhe), ka karo i te poke e pā ana ki te kounga o te karāhe.

Mā te pumau o te wera ka rite te tohatoha o te wera, ka ārai i ngā wāhi wera e puta ai ngā hapa o te karāhe (hei tauira, ngā mirumiru, te matotoru koretake).

He mea pai mō: Ngā taputapu whakaora, ngā rūma tirotiro, me ngā rohe rewa o te karāhe mānu, te karāhe ipu, me ngā oumu karāhe motuhake.

2.3 Te Rino me te Whakarewa: Te Tūpato ki te Rino Rewa me te Para

I roto i te hanga maitai, inā koa i roto i ngā oumu pewa hiko (EAF) me ngā oumu koko, ka tiakina e ngā Pereki Mullite Silica ngā taputapu mai i te maitai rewa, te para, me ngā hau pāmahana teitei:

Ka manawanui rātou ki te pakū me te pānga o te rere o te konganuku rewa, ka whakaiti i te horo o ngā pereki, ka whakaroa hoki i te roa o te ora o te arai oumu.

Mā te ātete ki te waikura rino me te waikura para ka ārai i te pakaru o te arai ka mutu ai te hanga utu nui.

Wāhi Whakamahinga: Te whakarārangi o ngā taha taha EAF, ngā raro koko, me ngā oko whakangao tuarua.

2.4 Ngā Poiha me ngā Tunu Ahi Ahumahi: Te Pupuri Wera Pono​

Ka pāngia ngā oumu para me ngā kohua ahumahi (hei tauira, mō te whakaputa hiko) e ngā pāmahana teitei me ngā hau putanga waikura. Ko ngā Pereki Silica Mullite e tuku ana i ēnei:

Te pupuri i te wera hei whakanui ake i te pai o te paipa, hei whakaiti i te whakapaunga wahie me ngā tukunga waro.

Ātete ki ngā hau waikawa (hei tauira, SO₂, HCl) mai i te tahunga para, te ārai i te pirau o ngā pereki, me te whakarite kia roa te mahi.

Horopaki Whakamahinga: Te whakarārangi o ngā oumu poiha, ngā rūma tahu para-ki-te-pūngao, me ngā mea whakahāngai wera.

2.5 Ētahi atu Wāhanga Pāmahana-Tiketike​

Ka kitea hoki ngā whakamahinga o ngā pereki silica mullite i roto i:

Ngā oumu uku:Mō te tahu i ngā taera uku, ngā taputapu horoi, me ngā uku matatau, ko te mea nui ko te whakahaere tika i te pāmahana.

Ngā Whare Whakamahana Hinu:I roto i ngā konganuku me ngā kaihanga whakakorikori, ātete ana ki te wera nui me te waikura hauwai.

Ngā Oumu Taiwhanga me ngā Oumu Rangahau:Mō ngā rangahau me ngā whanaketanga mātauranga me ngā ahumahi, ina kore e taea te whiriwhiri i te pumau i ngā pāmahana tino kino.
