Ibisobanuro bigufi:

Ingano y'inkono y'ibisigazwa:Ubushobozi bwo gutwara toni 15 - 80 (bwanogejwe neza hakurikijwe ingano ya EAF), uburemere bwa toni 20 - 70, ingano ya toni 10 - 45 m³, ingano zagenwe kuri buri tanuru rikoresha umuyoboro n'aho icyuma gihagarara. Trunnion: 34CrNiMo6 ikomeye cyane ifite umurambararo w'udupira twometseho imbaraga zo gukurura.

Ibikoresho n'Amahame ngenderwaho:ZG270-500 yahinduwe (Nb-V microalloyed), GS-20Mn5, ASTM A27 65-35 uburyo bwihariye bwo kuvura ubushyuhe. Ikurikiza ASTM A27, DIN 17182, EN 10293. Uburyo bwo kuvura ubushyuhe: Irazimye + Ikonjesha vuba kugira ngo imiterere y'ibinyampeke ibe myiza. Ubuso: Igikombe cy'imbere gifite uburebure bubiri (8°+12°) kugira ngo irekuremo ubushyuhe bufatana, igikonoshwa cy'inyuma gifite irangi ry'ibumba rya ceramic-epoxy ry'urwego rwinshi.

Uburyo bwo gukora:Integral imwe ikoresha uburyo bwo gusimbuza hamwe na sisitemu yo kwiruka ya EAF. EAF + LF + VD + argon bubbling (S≤0.012%, P≤0.015%). Isuzuma rya CAE rikoresha ubushyuhe - isuzuma rya virtual cycles 1.000. 100% NDT: Phased Array UT ku ngano yose, ACFM kuri radiyo ya trunnion blend, MT ku buso bwose bukoreshwa.

Ikoreshwa ry'Inkono y'Ibisuguti:Ingufu nyinshi cyane za AC/DC EAF (60-180t), gukora ibyuma bishingiye ku bisigazwa, gushonga kw'icyuma gishongesha/DRI, EAF y'icyuma kitagira umugese, amatanura y'icyuma akozwe mu byuma, amatanura y'icyuma akozwe mu byuma, n'ibikoresho byo gufata amatanura y'ifuru.

Ibirango by'ibicuruzwa

Incamake y'ibicuruzwa - Irushanwa rya EAF Slag Pot

An Inkono y'ibisuguti bya EAF(cyangwaifuru y'amashanyarazi ikoresha icyuma gishyushya) si ubwoko buto bw'inkono ya BOF ihindura imiterere gusa. Ikora munsi y'ubwoko butandukanye rwose bw'ibintu biyitera guhangayika bituma iba imwe mu nganda zikora ibyuma zisaba cyane.

Amatanura y'amashanyarazi akora ibintu bivanze mu byiciro buriIminota 45–90– akenshi ubushyuhe 12 kugeza kuri 20 ku munsi. Buri ruziga rukubiyemo:

1. Kuzuzahamwe n'ibisigazwa byashongeshejwe kuri 1.600–1.700°C (harimo n'ibitonyanga by'icyuma)

2. Gufatamu gihe inkono itwarwa mu nsi y'ubutaka butaringaniye

3. Guta imbundabinyuze mu kugorora k'umuyoboro, rimwe na rimwe bigatera ku nkombe z'aho umuyoboro w'amazi uherereye

4. Gukonjesha umwukakugeza munsi ya 300°C mbere y'uko kuzuza ikindi - bigatuma habaho ubushyuhe bwinshigushyuha cyane

5. Bitandukanye n'inkono za BOF zisanzwe zihabwa slag imwe kuri buri simburana, inkono za EAF zishobora gukorerwahogushyushya no gukonjesha vuba kugeza ku nshuro 20 ku munsiUku kuzenguruka kw'ubushyuhe bwinshi biteraumunaniro ukabije w'ubushyuhe– uburyo bwa mbere bwo gutsindwa ku nkono za EAF slag.

Byongeye kandi, ubuziranenge bwa EAF slag buratandukanye cyane bitewe n'ubwiza bw'ibisigazwa, inyongera za alloy, n'uburyo bwo gutunganya. Slag ishobora kuba ** yoroheje cyane** (CaO nyinshi, ifata) cyangwaaside(SiO₂ nyinshi, amazi). Buri kimwe gikenera imiterere y'imbere n'uburyo ibintu biyigaragaramo bitandukanye.

Womic Steel yateye imbereInkono z'ibisuguti zikozwe neza na EAFbikemura ibibazo bitatu byihariye:

●Umunaniro ukabije w'ubushyuhe– bikemurwa n'icyuma gito cyane + uburyo bwo gushyushya bugenzurwa n'ubushyuhe

●Gukonjesha ibisigazwa by'amazi– byakemuwe hakoreshejwe ibara ry’imbere rifite imiterere ibiri kandi rirwanya uduti

●Kwangirika kwa mashini mu gihe cyo gujugunya imyanda– bikemurwa n'inkombe ikomeye n'imiterere ifata ingaruka

Ifuru y'amashanyarazi ya EAF Slag Pot Electric Arc Furnace yihariye yo gukora ibyuma bikomeye cyane – Womic Steel

Kuki wahitamo Womic Steel kuri EAF Slag Pot yawe?

Ikiranga Akamaro ka EAF
Icyuma gikozwe muri mikorosoli ya Nb-V Ingano nto y'ibice bya niobium na vanadium pin, bitinda gutangira kwangirika kw'ubushyuhe. Byagaragaye ko byongera imikorere kugeza ku gutsindwa ku kigero cya 70% ugereranije n'icyuma gisanzwe.
Kuzimya byihuse + Gutemba Nyuma yo kwiyunga, umwuka uhatirwa (utari umwuka uhagaze) ukora imiterere myiza ya pearlite + bainite - ubudahangarwa bw’ubushyuhe buri hejuru cyane.
Igikombe cy'imbere gifite imigozi ibiri Agasozi ko hejuru ni 12°, agasozi ko hasi ni 8°, gafite agace karinganiye ka mm 150 aho umuntu yakubita. Igihe cyo kurekura slag cyagabanutseho 40% mu igeragezwa ryo mu murima.
** Irangi ririnda inkoni (Imbere)** Irangi rya alumina-silicate rifite ibice bibiri rishyirwamo ubugari bwa mm 3, rirwanya gufatana kw'ibanze kw'ibumba. Igihe cyo kongera gukoresha kirenga amezi 12.
Uburyo bwo gushushanya trunnion Ku nkono zirengeje toni 50, dushobora gutanga uduce duto tw’icyuma twakozwe n’utwo twateranijwe ukwatwo (dufunze neza + dusudira neza) kugira ngo tumara igihe kinini cyane.
FEA ihinduka hamwe no kugenzura ubushyuhe Dukoresha uruziga 1.000 rwa 800°C ΔT (gushyushya 300°C →1.600°C, gukonjesha 1.600°C →300°C) kugira ngo twemeze ko nta gucika kw'imashini. Raporo irimo.
Igishushanyo mbonera cy'ubushyuhe buke Ubunini bw'inkuta bukozwe neza bugabanya ubushyuhe mu gice cyo hejuru cy'uruziga - ahantu hakunze kugaragara cyane.
EAF Gukora Interface yihariye Duhindura imiterere y'inkono yo hejuru kugira ngo ihuze n'ifunguka ry'urugi rw'ifuru yawe n'imiterere y'umuyoboro wo gukanda - nta gusuka cyangwa gusuka.

Dutanga kandigahunda yo kugenzura ubwikorezi bw'ibinyabiziga bishongeshejwe n'amazi– dutoza abakozi banyu gukora UT mu kazi, kandi dusimbuza abakinnyi ku murongo wateganyijwe, tugagabanya igihe cyo kuruhuka kitateganijwe.

Ibibazo Bikunze Kubazwa (Ibibazo Bikunze Kubazwa) – EAF Specific

Q: Namenya nte ko EAF yanjye ikeneye icyuma cyihariye cyo gukaraba?
A: Niba ukoresha ubushyuhe burenze 10 ku munsi cyangwa ukagira imivuniko mu mezi 12 ku nkono zisanzwe, ukeneye igishushanyo mbonera cya EAF. Nanone, niba ubonye ko ibisigazwa bifashe cyane cyangwa bisaba kuvunika n'intoki, imiterere yacu yo kwirinda gufatisha izagufasha.

Q: Ese nshobora gukoresha icyuma kimwe cyo gusukamo slag kuri BOF na EAF?
A: Ntibyemewe – EAF pots zagenewe kwihuta mu gusiganwa, inkuta nto, n'imiterere itandukanye yo gufatana kw'ibisigazwa. Gukoresha BOF pots muri EAF bitera kwangirika vuba; gukoresha EAF pots muri BOF bishobora kuzishyushya cyane. Buri gihe koresha pots zabugenewe.

Q: Mutanga gahunda zo gutanga inkunga cyangwa zo guhanahana ingano?
A: Yego – dufite isafuriya y'icyuma nk'icyitegererezo cya serivisi: wishyura kuri toni y'icyuma cyakozwe, kandi ni twe dufite kandi tukabungabunga. Nibura imyaka 5. Saba ibisobanuro birambuye.

Q: Ni iyihe nshuro isanzwe yo kumara igihe cyo gutwikira irangi risanzwe?
A: Mu bikorwa bisanzwe bya EAF (ibisigazwa by'ibanze, iminota 15 ku munsi), irangi rimara amezi 9-12. Gusimbuza bishobora gukorwa mu ruganda rwawe n'abatekinisiye bacu (cyangwa dutanga ibikoresho byo gusimbuza). Igiciro cyo gusimbuza igisenge ni ~15% by'igiciro gishya cy'inkono.

Q: Wakwitwara ute mu gihe icyinjizwa cy’ibikoresho gitangiye gushya mu buryo bwihutirwa?
A: Dufite akantu gato ko kubikamo ibintu bishya (inkono 2-4) gasanzwe mu bubiko bwacu. Ku bakiriya bafite amasezerano yo gutanga serivisi, dutwara ibicuruzwa mu ndege mu masaha 72.

Q: Ese ushobora kongeramo ibikoresho bipima ubushyuhe mu nkono?
A: Yego – dushobora gushyiramo imifuka ya thermocouple (ahantu hagera kuri 4) dukoresheje Inconel sheathing. Sensors zishobora guhuzwa na monitor igendanwa cyangwa zigahuzwa na DCS y'uruganda rwawe.

Q: Ni iki gisabwa kugira ngo EAF slag ifatanye?
A: Igikombe cy'imbere kigomba kuba gikozwe mu mashini ipima Ra ≤ 6.3 μm. Ubuso bukozwe mu buryo bwa "as-cast" butuma gifatana. Igishushanyo cyacu gifite imiterere ibiri hamwe n'uburyo bwo gukora neza bigabanya gufatana cyane.

Q: Nakora iki ngo nsukure isafuriya y'ibisuguti niba ibisuguti byakonjeshejwe imbere?
A: Ntugakoreshe uburyo bwo gukubita ku rukuta rw'inkono - ibyo bitera imiturire. Ahubwo, koresha uburyo bwo gukata umuyoboro wa ogisijeni, hanyuma ushyushye inkono neza. Uburyo bwacu bwo gutwikira bugabanya impanuka.

Witeguye kunoza uburyo bwo gucunga ibishishwa bya EAF?
