Imbiza Yezinhlayiya Ezingamathani angu-20-50 | Iladi Yezinhlayiya Ezinomthamo Ophakathi Yokwenza Insimbi ye-EAF ne-LF – Insimbi Yomzimba

Incazelo emfushane:

Usayizi Webhodwe Le-Slag:Umthamo wamathani angu-20 – 50 (ngokwezifiso), isisindo samathani angu-25 – 60, umthamo ongu-15 – 35 m³, ubukhulu ngomdwebo ngamunye. I-Trunnion: i-cast-in 35CrMo noma i-40Cr ene-fillet eqinisiwe.

Izinto kanye namazinga:I-ZG270-500, ZG310-570, GS-20Mn5, ASTM A27 65-35. Ihambisana ne-ASTM A27, DIN 17182, ISO 3755, JIS G7821. Ukwelashwa ngokushisa: Okujwayelekile + Okuthambile. Umphezulu: ongaphakathi ofakwe kuphrofayili yokulwa nokunamathela, ukuqhuma kwangaphandle kokudubula + ukugqoka kwe-aluminium okushisa okuphezulu.

Inqubo Yokukhiqiza:Ukuphonswa kwe-integral okuyingxenye eyodwa – akukho ukuthungwa kwe-weld. I-EAF + LF + VD degassing (S≤0.020%, P≤0.020%). Ukulingisa ukuqina kwe-CAE. 100% NDT: UT (Izinsika Zezinga 1, umzimba Wezinga 2), MT, PT. I-UT ye-Phased Array ekhethwayo.

Ukusetshenziswa kwe-Slag Pot:I-EAF ephakathi nendawo (50-100t), ukucwenga kwe-LF, ama-converter amancane e-BOF, ama-foundries, ama-smelter ethusi/i-nickel, ukuthuthwa kwe-slag ezitshalweni zensimbi.

Insimbi YaseWomicinikeza izimbiza ze-slag eziphakathi nendawo ezenzelwe imijikelezo engu-5,000–8,000 enokumelana nokukhathala okuphezulu kokushisa. Ukufakwa kwethu okuhlanganisiwe kususa imifantu yomugqa wokushisela. Idizayini eyenziwe ngokwezifiso yamandla akho e-crane akhona. Isitifiketi se-ISO, i-PED. Ukulethwa okusheshayo (izinsuku ezingu-35–55). Thola isilinganiso sakho sembiza ye-slag ephakathi nendawo namuhla.

Ukubuka Konke Komkhiqizo - Kungani Izimbiza Eziphakathi Ziyi-Medium Slag Ziyi-Backbone Yezigayo Eziningi Zensimbi

Izimbiza ze-slag eziphakathi nendawo(amathani angu-20–50) yizitsha zokuphatha i-slag ezivame kakhulu ezigayweni zensimbi ezincane kuya kweziphakathi, izitshalo zensimbi ezikhethekile, kanye nezindawo zokusekela. Zikhonza izinhlobo eziningi zesithando somlilo:

●I-EAF engamathani angu-50–100(ukwenziwa kwensimbi okuvame kakhulu okusekelwe ezilahlweni)

●Izitofu ze-LF ladlekokucwengisisa kwesibili

●Ama-converter e-BOF afinyelela kumathani ayi-120(ukuhlukaniswa kwe-slag)

●Izincibilikisi ezingezona i-ferrous(ithusi, i-nickel, i-lead)

●Izindawo ezinkulu zokuthungangezitofu zokungenisa ezingamathani angu-30–60

Ngokungafani nezimbiza ezincane (5–15t) ezivame ukusetshenziswa emisebenzini eminingi, noma izimbiza ezinkulu (60–100t) zezigayo ezinkulu ezihlanganisiwe, izimbiza eziphakathi zisebenza ku-ukugibela ibhayisikili okumaphakathi kodwa okunamandla– ngokuvamile ukushisa okungu-10–15 ngosuku, izinsuku ezingu-5–6 ngesonto. Kudinga ibhalansiumthamo, ukuqina, kanye nezindleko.

Imodi yokuhluleka eyinhloko yamabhodwe aphakathi akuyona ukukhathala kokushisa (njengasemabhodweni e-EAF) noma ukuqhekeka (njengasemabhodweni e-BOF) - kuyi-umthelela womshini + ukushaqeka kokushisa kuhlangeneAmabhodwe aphakathi nendawo avame ukuthuthwa phezu kwezitezi eziqinile, athambeke ngama-crane angacacile, futhi ngezinye izikhathi agcinwe ngaphandle, okuholela ekupholeni okungalingani.

I-Womic Steel ithuthukise ukwakheka kwembiza yethu ye-slag ephakathi ukuze ibhekane nalezi zinselele ezithile:

●Ukumelana okunamandla okunamandla- ungqimba olukhulu kanye nokuqinisa phansi

●Ukunciphisa ukugxilisa ingqondo ekucindezelekeni- i-fillet radii enkulu kuzo zonke izinguquko

●Isibonelelo sokugqwala sendawo yokugcina izinto yangaphandle– ukujiya kodonga okungu-3mm okwengeziwe ezindaweni zangaphandle

Imbiza Yezinhlayiya Ezingamathani angu-20-50 Iladle Yezinhlayiya Ezinomthamo Ophakathi Yokwenza Insimbi ye-EAF ne-LF – Insimbi Yomzimba

Kungani Kufanele Ukhethe Insimbi Yomzimba Emabhodweni Akho E-Slag Aphakathi?

Isici	Inzuzo Yezigayo Eziphakathi
Ubukhulu Bodonga Obulungiselelwe	Ubukhulu obungu-10–15% kunokwejwayelekile, kodwa bungaphansi kwamathani angu-60 – bufanela iningi lama-crane aphakathi nendawo (umthamo wamathani angu-50–80).
Indawo Yomphetho Oqinisiwe	Ubukhulu obungu-25% endaweni yokuphazamiseka kwe-slag + imichilo yokuguguleka engashintshwa (uma uthanda) – kunciphisa ukuguquguquka okuvela ekulahleni ngokunganaki.
Ikhemistri Elawulwayo Enezakhi Zokulandelela	I-Cr (0.3%) kanye ne-Ni (0.3%) eyengeziwe ithuthukisa ukuqina futhi ithinta ukuqina emazingeni okushisa aphansi.

Imibuzo Evame Ukubuzwa (Imibuzo Evame Ukubuzwa) – Izimbiza Ze-Slag Eziphakathi

U: Uyini umehluko phakathi kwebhodwe le-slag “eliphakathi” kanye neli “likhulu”?
A: Akuyona nje usayizi. Izimbiza eziphakathi nendawo zenzelwe ukusetshenziswa okujwayelekile kanye nemvamisa yokujikeleza (10–15/ngosuku). Izimbiza ezinkulu (ezingaphezu kuka-60 t) zakhelwe izigayo ezihlanganisiwe ezinemijikelezo ehamba kancane kodwa ukumelana okuphezulu kokukhukhuleka. Sinemithetho yokuklama ehlukile yesigaba ngasinye.

U: Ngingayisebenzisa yini imbiza ye-slag ephakathi nendawo ye-BOF slag?
A: Yebo, kuma-converter e-BOF angafika kumathani ayi-120. Kodwa-ke, i-BOF slag ayinamatheli kakhulu kodwa inamandla kakhulu ngamakhemikhali. Sincoma i-ZG310-570 noma i-GS-20Mn5 ukuze ihlale isikhathi eside.

U: Ukuvimbela kanjani ukulimala kwe-trunnion ngesikhathi sokuthuthwa?
A: Sifaka izivalo zensimbi ezisuswayo phezu kwezinsika bese sibopha imbiza ngezintambo eziboshwe ngqo emzimbeni - hhayi ezinsika. Imiyalelo eningiliziwe yokuphakamisa nokuthumela ifakiwe.

U: Ingabe ninikeza upende we-slag enamathelayo kakhulu (isb., i-high-MgO)?
A: Yebo – sine-epoxy coating efakwe ngobumba ekwazi ukumelana nokushisa okungu-1,200°C. Ifakwa ubukhulu obungu-2mm futhi ihlala izinyanga ezingu-8-12. Ukufaka kabusha kungenziwa endaweni.

Q: Iyini iwaranti yakho yezimbiza ze-slag eziphakathi nendawo?
A: Izinyanga ezingama-24 / imijikelezo engu-5,000, noma yikuphi okuza kuqala. Lokhu kuhlanganisa ukuqhekeka odongeni kanye nokwehluleka kwe-trunnion. Ukuguguleka kokumboza, ukusetshenziswa kabi kwemishini, kanye nokusetshenziswa okungafanele akufakiwe.

U: Ungakwazi yini ukunikeza izimbiza ze-slag ngaphandle komshini wokugaya (njengobuso bangaphakathi obubunjiwe)?
A: Sikweluleka kakhulu ukuthi ungakwenzi lokho. Umshini wokusika ubalulekile ukuze kukhishwe i-slag. Kodwa-ke, uma wamukela izindleko zokuhlanza eziphakeme, singakunikeza njengomshini ohlanganisiwe onesaphulelo sentengo esingu-~12%.

U: Ngizigcina kanjani izimbiza ze-slag eziphakathi nendawo uma zingasetshenziswa?
A: Gcina emapulangweni okhuni, hhayi ngqo phansi. Zigcine zimboziwe ukuze kugwenywe ukupholisa imvula endaweni eyodwa. Jikelezisa amabhodwe asebenza ukuze usakaze ukucindezeleka kokushisa.

Q: Yisiphi isikhathi esijwayelekile sokuhola i-oda lembiza ye-slag ephakathi nendawo?
A: Kumandla ajwayelekile (amathani angu-20, 30, 40, 50) ane-ZG270-500 noma i-ZG310-570, isikhathi sokuhola siyizinsuku ezingu-35-45. Ukuze uthole izinto ezikhethekile noma ukuhlolwa komthelela, engeza izinsuku ezingu-10-15.
