Mphika wa LF/VD Slag | Chidebe chapadera cha Ladle Furnace cha Metallurgy Yachiwiri - Chitsulo cha Womic

Kufotokozera Kwachidule:

Kukula kwa Mphika wa Zinyalala:Kuchuluka kwake ndi matani 5 - 40 (kufanana ndi kuchuluka kwa LF slag), kulemera kwake ndi matani 8 - 45, voliyumu 4 - 25 m³, miyeso yake ndi yokonzedwa kuti igwiritsidwe ntchito pa ng'anjo yogwirira ntchito ndi chitseko cha slag. Trunnion: kapangidwe kake kotsika komanso kopanda mawonekedwe owonekera bwino.

Zipangizo ndi Miyezo:ZG270-500+ (S≤0.012%, P≤0.015%), GS-20Mn5V (yokhala ndi vanadium), ASTM A27 65-35 yotsika kwambiri ya haidrojeni. Yogwirizana ndi ASTM A27, DIN 17182, EN 10293, ISO 3755. Kuchiza kutentha: Kuphika kozimitsidwa + Kofewa + Kopanda madzi. Pamwamba: mkati ndi mawonekedwe osalala a radius kuti athandize kuyenda kwa slag yopangidwa, kunja ndi chophimba champhamvu cha emissivity kuti kuziziritse kwa radiative.

Njira Yopangira:Chogwirizira chimodzi chopangira mpweya chomwe chimayang'ana kwambiri kulimba kwa mpweya pa ntchito za VD. EAF + LF + VD + kutulutsa mpweya kwa nthawi yayitali (H < 1.5ppm). Kuyerekeza kwa madzi otentha a CAE pochotsa slag. 100% NDT: Kuyesa kwa UT yonse (Level 1 trunnion, Level 2 body), MT, PT, komanso mayeso a helium leak kuti agwiritsidwe ntchito mu vacuum.

Kagwiritsidwe Ntchito ka Mphika wa Zinyalala:Kusamalira slag yopangidwa ndi ladle furnace (LF), kusonkhanitsa slag yochotsa mpweya mu VD/VOD, kunyamula slag kuchokera ku siteshoni yachiwiri ya zitsulo, kukonza chitsulo chopangidwa ndi alloy, mafakitale apadera achitsulo (chitsulo chonyamula, chitsulo chapaipi, chitsulo cha masika), chogwirira slag cha AOD chosapanga dzimbiri, kuphatikiza kwa makina ozindikira slag.

Chitsulo cha Womicimapereka miphika ya slag yokonzedwa bwino ya LF/VD yokhala ndi hydrogen yochepa kwambiri (≤1.5 ppm) kuti isasweke chifukwa cha hydrogen pansi pa vacuum. Ma radii athu osalala osinthira amachotsa madera akufa komwe slag yopangidwa imatha kusonkhana. Mapangidwe apadera a kapangidwe kake ka ng'anjo ya ladle. ISO 9001, PED, NORSOK M-650 yovomerezeka. Pemphani satifiketi yogwirizana ndi vacuum.

Chidule cha Zamalonda - Zofunikira Zapadera za Miphika ya LF/VD Slag

A Mphika wa LF slag(chidebe cha ng'anjo ya ladle) kapenaMphika wa VD slag(chidebe chotsukira mpweya chopanda mpweya) zogwiriraslag yopangidwa– osati phula lamphamvu, lotentha kwambiri lochokera ku EAF kapena BOF, koma chisakanizo chosakanikirana bwino cha laimu, fluorspar, ndi alloys zopangidwa kuti zitsuke chitsulo chosungunuka.

Kodi n’chiyani chimasiyanitsa miphika ya LF/VD slag?

1. Kutentha kwa slag ndi kotsika (~1,500°C vs 1,650°C pa EAF), koma nthawi yogwira ntchito ndi yayitali kwambiri.– nthawi zina mphindi 60–90 pa kutentha kulikonse. Mphika uyenera kupirira kutentha kulikonsekusintha kwa kayendedwe ka madzikutentha kwambiri nthawi zonse.

2. Dothi lopangidwa ndi zinthu zopangidwa ...Malo akufa kapena ngodya zakuthwa zamkati zimayambitsa kudzikundikira kwa matope komwe kumachepetsa mphamvu pakapita nthawi.

3. Kuchotsa gasi m'malo otayira mpweya (VD) kumafuna chinthu chapadera: mphika wa slag ukhoza kuyikidwa pansi pa vacuum (0.5–1 torr) kwa nthawi yochepa. Kanthu kakang'ono kalikonse mu casting kangathe kutulutsa mpweya, zomwe zimapangitsa kutikupangika kwa thovu mu chitsulokapena - choipa kwambiri -kuphulika kwa mphikangati pali chivundikiro chachikulu.

4. Miphika ya LF/VD nthawi zambiri imayendetsedwa ndi ndevu yomweyi yomwe imakweza ndevu yachitsulo.Izi zikutanthauza kuti mphika uyenera kukhala wopepuka komanso wopapatiza kuposa miphika ya EAF/BOF kuti ugwirizane ndi malo a turret arm ndi geometry ya crane hook.

5. Mankhwala a slag ndi osavuta (CaO/Al₂O₃ yokwera), yomwe imaukira malire a tirigu wa silicon ndi aluminiyamu.Kusamala kwambiri ndi zinthu zomwe sizili zachitsulo ndikofunikira.

Miphika ya LF/VD ya Womic Steel yapangidwa ndikuchuluka kochepa kwambiri kwa haidrojeni, mawonekedwe osalala amkatindimiyeso yolondola yopapatiza- zomwe kwenikweni zimafuna pakupanga zitsulo zachiwiri.

Mafunso Ofunsidwa Kawirikawiri (FAQ) - LF/VD Specific

Q: N’chifukwa chiyani kuchuluka kwa haidrojeni n’kofunika kwambiri pa miphika ya slag?
Yankho: Pa nthawi yochotsa mpweya mu vacuum, haidrojeni yosungunuka mu chitsulo imatha kufalikira ndikusakanikirana kukhala molekyulu ya haidrojeni pamalo omwe si achitsulo. Izi zimapangitsa kuti pakhale kupanikizika kwamkati, zomwe zimapangitsa kuti pakhale matuza kapena ming'alu - nthawi zina amatchedwa "hydrogen flaking." Miphika ya LF/VD imakhala yotetezeka chifukwa imasungidwa pansi pa vacuum kwa nthawi yayitali.

Q: Kodi mungatsimikizire kuchuluka kwa haidrojeni m'madzi kufika pa <1.0 ppm?
Yankho: Inde, koma kumafuna njira yapadera yosungunula (vacuum induction melting kapena electroslag remelting) ndipo imadula kwambiri. Pa ntchito zambiri, 1.5 ppm ndi yokwanira.

Q: Kodi mumapereka mayeso a vacuum leak?
A: Inde, timayesa kutayikira kwa helium ngati tipempha ndipo timapereka satifiketi motsatira ISO 20485. Timatsimikizira kuchuluka kwa kutayikira kwa madzi <1×10⁻⁶ mbar·l/s.

Q: Kodi miphika ya LF slag iyenera kusinthidwa kangati?
A: Kawirikawiri zaka 3-5 zilizonse, kutengera nthawi yomwe zinthu zikuyendera. Kusintha kwa kayendedwe ka madzi ndi chinthu chachikulu chomwe chimalepheretsa moyo. Kuwunika kwa UT pachaka kumatha kuzindikira malo obisika a madzi.

Q: Kodi mungapereke miphika ya slag ndi jekete loziziritsira mpweya?
A: Pa ntchito za LF zomwe zimafuna kuziziritsidwa mwachangu tisanagwiritse ntchito kachiwiri, tikhoza kupanga jekete la mpweya logwirizana (chipolopolo chakunja chachitsulo chokhala ndi njira zopumira). Izi zimachepetsa nthawi yoziziritsira kuyambira mphindi 90 mpaka mphindi 20.

Q: Kodi miphika yanu ya LF slag imagwirizana ndi makina odziwira okha slag level?
Yankho: Inde. Timapereka choyikapo chathyathyathya pamphepete mwa choyezera radar kapena laser. Kapena, titha kuyika ma thermocouple kuti tizindikire slag layer.

Q: Kodi mumapereka maphunziro owunikira mphika wa LF?
A: Inde, timapereka maphunziro a tsiku limodzi pamalopo kwa gulu lanu lokonza: UT ya ma trunnions, njira zowunikira maso, ndi njira zokonzera ming'alu.

Q: Kodi chitsimikizo cha nthawi zonse cha mphika wa LF/VD slag ndi chiyani?
A: Miyezi 24 kapena ma cycle 10,000 - chilichonse chomwe chimabwera poyamba. Pa ntchito yochotsa mpweya (ndi mayeso otuluka), chitsimikizo chimakulitsidwa mpaka miyezi 36 kuti hydrogen isasweke.
