Tirohanga Whānui mō te Hua – Ngā Hiahia Motuhake o ngā Kohua Para LF/VD

A Kohua para LF(ipu para o te oumu koko) rāneiKohua para VDngā kakau (pākete para whakakore hau)para hangai– ehara i te para werawera, kaha hoki mai i te EAF, i te BOF rānei, engari he ranunga kua ata whakaranua o te raima, te fluorspar, me ngā koranu i hangaia hei whakapai ake i te maitai rewa.

He aha te mea e rerekē ai ngā kohua para LF/VD?

1. He iti iho te pāmahana para (~1,500°C, whakaritea ki te 1,650°C mō te EAF), engari he roa ake te wā pupuri.– i ētahi wā 60–90 meneti mō ia wera. Me ātete te kohuate whakarerekētanga ngokingokii te pāmahana tiketike tonu.

2. He tino wai te para hangai ina rewa, engari ka tino piri ina whakamatao.Ka puta te putunga paru i ngā rohe mate, i ngā kokonga koi rānei o roto, ā, ka whakaiti i te kaha o te paru i te roanga o te wā.

3. He whakaritenga motuhake tā te tango hau korehau (VD): ka taea te whakanoho i te kohua para ki raro i te korehau (0.5–1 torr) mō ngā wā poto. Ka taea e te moroiti i roto i te whakarewanga te whakaputa hau, ka arahi kite hanganga o te mirumiru i roto i te maitairānei – kino atu rānei –te pahūtanga o te kohuamehemea he kōhao nui kei reira.

4. Ko te pourewa koko kotahi e hiki ana i te koko rino te nuinga o te wā e mau ai ngā kohua LF/VD.Ko te tikanga o tēnei me mama ake te kohua, me kiato ake i ngā kohua EAF/BOF kia uru ki roto i te tawhiti o te ringa pourewa me te āhua o te matau kerēne.

5. He taketake te matū o te para (he nui te CaO/Al₂O₃), e whakaeke ana i ngā rohe o te kōpaka silicon me te konumohe.Me aro nui ki ngā whakaurunga kore-whakarewa.

He mea hanga ngā kohua para LF/VD a Womic Steel kitino iti te ihirangi hauwai, ngā āhua o roto maeneene, mengā inenga kiato tika– koia tonu te mea e hiahiatia ana e te mahi whakarewa tuarua.

Ngā Pātai Auau (FAQ) – Motuhake ki te LF/VD

P: He aha te hiranga o te nui o te hauwai mō ngā kohua para?
A: I te wā e tangohia ana te hau mā te korehau, ka horapa te hauwai rewa i roto i te whakarewa maitai, ka hono anō ki te hauwai ngota i ngā whakaurunga kore-whakarewa. Ka puta he pēhanga ā-roto, ka puta he pupuhi, he ngatata rānei – ka kiia i ētahi wā ko te "hauwai pakarukaru." Ka ngawari te whakamahi i ngā kohua LF/VD nā te mea ka puritia i raro i te korehau mō ngā wā roa.

P: Ka taea e koe te whakamana i te ihirangi hauwai ki raro i te 1.0 ppm?
Āe, engari me mahi rewa motuhake (rewa whakapūmau korehau, whakarewa anō rānei i te para hiko) ā, he nui ake te utu. Mō te nuinga o ngā tono, he rawaka te 1.5 ppm.

Q: Kei te whakarato koe i ngā whakamātautau turuturu korehau?
Āe, ka whakahaerehia e mātou he whakamātautau turuturu helium ina tonoa mai, ā, ka tukuna he tiwhikete e ai ki te ISO 20485. Ka oati mātou ko te tere turuturu <1×10⁻⁶ mbar·l/s.

P: Kia pēhea te auau o te whakakapinga o ngā kohua para LF?
A: I ia 3-5 tau te tikanga, i runga i ngā huringa. Ko te rerekētanga ngokingoki te mea matua e whakawhāiti ana i te ora. Mā te tirotiro UT ā-tau ka taea te kite i ngā āputa ngokingoki wawe.

Q: Ka taea e koe te whakarato i ngā kohua para me te koti hau whakamatao?
A: Mō ngā tono LF e hiahia ana kia tere te whakamatao i mua i te whakamahinga e whai ake nei, ka taea e mātou te hoahoa i tētahi koti hau whakauru (he anga waho maitai me ngā awa hau). Mā tēnei ka whakaitihia te wā whakamatao mai i te 90 meneti ki te 20 meneti.

Q: Kei te hototahi ō kohua para LF ki ngā pūnaha kimi taumata para aunoa?
Āe. Ka whakaratohia e mātou he papa whakapiri papatahi ki te awhi mō te pūoko radar, te pūoko laser rānei. Tērā atu rānei, ka taea e mātou te whakauru i ngā takirua wera hei kimi i te paparanga paru.

Q: Kei te tuku whakangungu koe mō te tirotiro i te kohua LF?
Āe, ka whakaratohia e mātou he whakangungu kotahi te rā ki te papaanga mō tō rōpū tiaki: te UT o ngā trunnions, ngā paearu tirotiro tirohanga, me ngā tikanga whakatika ngatata.

Q: He aha te pūtāhui noa mō te kohua para LF/VD?
A: 24 marama, 10,000 huringa rānei – ko tēhea te mea ka tae tuatahi mai. Mō te ratonga korehau (me te whakamātautau turuturu), ka whakaroahia te whakamana ki te 36 marama mō te pakaru hauwai.
