Tirohanga Whānui mō te Hua – He aha ngā Ipu Para Waenga te Tuara o te Maha o ngā Mira Rino

Ngā kohua para waenga(20–50 tāne) ngā oko whakahaere para e tino kitea ana i roto i ngā mira maitai iti ki te rahi waenga, ngā wheketere maitai motuhake, me ngā whare hanga whakarewa. He maha ngā momo oumu e whakamahia ana e rātou:

●50–100 tāne EAF(te hanga maitai para e tino kitea ana)

●Ngā oumu koko LFmō te whakamahine tuarua

●Ngā kaitahuri BOF tae atu ki te 120 tana(te wehenga o te para)

●Ngā mīhini whakarewa kore-ferrous(parahi, nikara, mata)

●Ngā whare hanga whakarewa nuime ngā oumu whakapūngao 30–60 tana

Kāore i rite ki ngā kohua iti (5–15t) e whakamahia ana i roto i ngā mahi puranga, ki ngā kohua nui rānei (60–100t) mō ngā mira whakauru nunui, ka mahi ngā kohua waenga i tete eke pahikara ngawari engari kaha– he 10–15 ngā whakamahana i te rā, 5–6 ngā rā i te wiki. Me taurite tete kaha, te roa, me te utu.

Ko te momo rahunga matua mō ngā kohua reo ehara i te ngenge wera (pērā i ngā kohua EAF) te ngokingoki rānei (pērā i ngā kohua BOF) – engaripānga ā-mīhini + ru wera kua whakakotahihiaHe maha ngā wā ka haria ngā kohua waenga i runga i ngā papa taratara, ka whakatītahatia ki ngā kereini kāore i te tino tika, ā, i ētahi wā ka rongoatia ki waho, ka hua ake te whakamatao kāore i te ōrite.

Kua arotauhia e Womic Steel te hoahoa o tā mātou kohua para waenga hei aro atu ki ēnei wero motuhake:

●Te ātete pānga whakarei ake– he whakakaha matotoru ake mō te taha me te raro

●Te whakaiti i te kukū o te ahotea– ngā radius mite nui ake i ngā whakawhiti katoa

●Te ātete ki te waikura mō te rokiroki o waho– he matotoru pakitara 3mm tāpiri i runga i ngā mata o waho

Kohua Para 20-50 Tana, Kohua Para Kaha Waenga mō te Hanga Rino EAF me te LF – Womic Steel

He aha i whiriwhiri ai koe i te maitai Womic mō āu kohua para waenga?

Āhuatanga	Painga mō ngā Mira Waenga
Matotoru Pakitara Kua Arotauhia	He matotoru ake i te paerewa, 10–15% engari he iti iho i te 60 tāne te taumaha – e tau ana ki te nuinga o ngā kerēne mira reo-rahi (50–80 tāne te kaha).
Rohe Awhi Whakakaha	25% te matotoru ake i te wāhi pānga o te para + ngā rīpene kakahu ka taea te whakakapi (whiringa) – ka whakaiti i te rerekētanga o te ahua o te maka koretake.
Matū Whakahaeretia me ngā Huānga Whaiaro	Mā te tāpiri o te Cr (0.3%) me te Ni (0.3%) ka pai ake te mārō me te kaha o te pānga ki ngā pāmahana iti o te taiao.
Te Makahanga Trunnion Whakauru Katoa	Ko ngā poro rakau i whakarewaina ngātahitia me te konganuku tāpiri ki roto i te pakiaka – e hipa ana i ngā paerewa FEM mō te hiki.
Taurangi Whakaoti Mata	I mīhinihia te peihana o roto ki te ≤6.3µm Ra, te mata o waho ki te ≤25µm Ra – ka whakaiti i te piri o te paru me te wā horoi.
Kōnae Hoahoa 10-Tau	Ka puritia e mātou te CAD o tō kohua, te whakatauira maka, ngā tuhinga NDT, me te tātari matū mō te tekau tau – kia taea ai te whai i ngā arotake.
Ratonga Wāhanga Eke Tere	Ka tukuna ngā mowhiti whakakapinga, ngā taupoki trunnion, me ngā kete whakatika paninga i roto i ngā wiki e rua.

Kei te tuku hoki a Womic Steel i ngāhoahoa whakahou– mēnā kei a koe ngā kohua waenga kāore i te pai te mahi, ka taea e mātou te tātari i tō rātou aratau rahunga me te whakarato whakakapinga me te āhua kua whakatikahia.

Ngā Pātai Auau (FAQ) – Ngā Ipu Para Waenga

P: He aha te rerekētanga i waenga i te kohua para "waenga" me te kohua "nui"?
A: Ehara i te rahi anake. Ko ngā kohua waenga he mea hanga mō te auau huringa waenga (10–15/rā) me te whakamahinga whānui. Ko ngā kohua nui (60+ tana) he mea hanga mō ngā mira whakauru he puhoi ake ngā huringa engari he ātete ki te ngoki. He ture hoahoa motuhake ā mātou mō ia kāwai.

Q: Ka taea e au te whakamahi i tētahi kohua para waenga mō te para BOF?
Āe, mō ngā kaitahuri BOF tae atu ki te 120 tāne. Heoi, he iti ake te piri o te para BOF engari he kaha ake te matū. Ka tūtohu mātou i te ZG310-570, i te GS-20Mn5 rānei mō te roa o te ora.

Q: Me pēhea te ārai i te kino o te trunnion i te wā e kawe ana?
A: Ka tāpirihia e mātou he taupoki rino tango ki runga i ngā poupou, ā, ka herea te kohua ki te mekameka tika ki te tinana – kāore rawa ki runga i ngā poupou. Kei roto ngā tohutohu taipitopito mō te hiki me te tuku.

Q: Kei a koutou he paninga mō te para tino piri (hei tauira, he nui te MgO)?
Āe – he paninga epoxy kua whakakikoruatia ki te uku e tu ana i te 1,200°C. E 2mm te matotoru o te paninga, ā, e 8–12 marama te roa. Ka taea te pani anō i te wāhi.

Q: He aha tāu pūtāhui mō ngā kohua para waenga?
A: 24 marama / 5,000 huringa, ko tēhea te mea ka tae tuatahi mai. Ka hipokina e tēnei te pakaru o te pakitara me te pakaru o te pou. Kāore i roto i tēnei te pakaru o te paninga, te tukino ā-mīhini, me te whakamahinga hē.

Q: Ka taea e koe te tuku i ngā kohua para me te kore e whakamahia he mīhini (hei mata o roto)?
A: Kāore mātou e tino tohutohu ana kia pērā. He mea nui te mahi mīhini hei tuku i te paru. Heoi, ki te whakaae koe ki ngā utu horoi teitei ake, ka taea e mātou te tuku atu i te mea whakarewa me te whakahekenga utu o te ~12%.

P: Me pēhea taku penapena i ngā kohua para waenga ina kore e whakamahia?
A: Penapenahia ki runga i ngā papa rakau, kaua ki runga i te whenua. Puritia kia taupokina kia kore ai e mātao tetahi wāhi i te ua. Hurihia ngā kohua kia tohatohahia te ahotea wera.

Q: He aha te wā ārahi noa mō te ota kohua para reo?
A: Mō ngā kaha paerewa (20, 30, 40, 50 tana) me te ZG270-500, ZG310-570 rānei, ko te wā arahi he 35–45 rā. Mō ngā rauemi motuhake, mō ngā whakamātautau pānga rānei, tāpirihia kia 10–15 rā.
