Tsananguro pfupi:

Saizi yehari yeSlag:Kugona kwayo matani 5 - 40 (inoenderana nehukuru hweLF slag), huremu matani 8 - 45, vhoriyamu 4 - 25 m³, saizi dzakagadzirirwa chikuva chekushanda nechoto uye kupinda kwegonhi rechoto. Trunnion: dhizaini isina kusimba ine offset kusvika pakuchenesa choto.

Zvinyorwa & Maitiro:ZG270-500+ (S≤0.012%, P≤0.015%), GS-20Mn5V (ine vanadium), ASTM A27 65-35 ine hydrogen grade yakaderera. Inoenderana neASTM A27, DIN 17182, EN 10293, ISO 3755. Kurapa kupisa: Yakadzimwa + Yakanyoroveswa + yakabviswa hydrogenation. Pamusoro: yemukati ine radius yakatsetseka kubatsira synthetic slag kuyerera, yekunze ine emissivity coating yakawanda yekutonhodza radiative.

Maitiro Ekugadzira:Chinhu chinoshandiswa nemagetsi chimwe chete, kunyanya kusimba kwegasi pakushanda kweVD. EAF + LF + VD + kubvisa gasi kwenguva refu (H < 1.5ppm). CAE thermal-fluid simulation yekubvisa slag. 100% NDT: UT yakazara vhoriyamu (Level 1 trunnion, Level 2 body), MT, PT, pamwe ne helium leak test ye vacuum service.

Kushandiswa kweSlag Pot:Kubata machira ekugadzira echitofu (LF), kuunganidzwa kwemarara ekugadzira eVD/VOD, kutakurwa kwemarara ekugadzira kubva kunzvimbo dzesimbi dzechipiri, kunatswa kwesimbi ye alloy, zvivakwa zvesimbi zvemhando yepamusoro (simbi ine mabheya, simbi yemapaipi, simbi yespring), kubata marara esimbi isina tsvina yeAOD, kubatanidzwa kwesystem yekuona marara.

Simbi yeWomicInopa mapoto eslag akagadziriswa neLF/VD ane hydrogen yakaderera zvakanyanya (≤1.5 ppm) kudzivirira kutsemuka kunokonzerwa nehydrogen pasi pevacuum. Radii yedu inochinjika inobvisa nzvimbo dzakafa apo slag yakagadzirwa inogona kuungana. Magadzirirwo akagadzirwa echero ladle furnace turret layout. ISO 9001, PED, NORSOK M-650 yakasimbiswa. Kumbira chitupa chekuenderana nevacuum.

Pfupiso yeChigadzirwa - Zvinodiwa Zvakasiyana zveLF/VD Slag Pots

A Hari yeLF slag(mudziyo wekuisa chitofu chendiro) kanaHari yeVD slag(bhaketi rekubvisa gasi) rinobata zvinhutsvina yakagadzirwa- kwete tsvina ine simba, inopisa zvakanyanya kubva kuEAF kana BOF, asi musanganiswa wakanyatsogadzirwa we lime, fluorspar, uye alloys zvakagadzirirwa kunatsa simbi yakanyungudutswa.

Chii chinoita kuti hari dzeLF/VD slag dzisiyane?

1. Kupisa kwetsvina kwakaderera (~1,500°C vs 1,650°C yeEAF), asi nguva yekubata inguva yakareba zvikuru– dzimwe nguva maminetsi makumi matanhatu kusvika makumi mapfumbamwe pakupisa kwega kwega. Hari inofanira kurambakushanduka kwesimbapakupisa kwakanyanya kwenguva refu.

2. Tsvina yakagadzirwa inonyorova zvikuru kana yanyungudutswa asi inonamira zvakanyanya painotonhora.Nzvimbo dzakafa kana makona emukati akapinza anokonzera kuungana kwemarara izvo zvinoderedza kugona kwenzvimbo yacho nekufamba kwenguva.

3. Kubvisa gasi mu vacuum (VD) kunoda chimwe chinhu chakakosha: hari yeslag inogona kuiswa pasi pevacuum (0.5–1 torr) kwenguva pfupi. Chero microporosity iri mu casting inogona kubuda gasi, zvichikonzerakuumbwa kwemabubble musimbikana – zvakatoipa –kupwanywa kweharikana paine mukaha mukuru.

4. Hari dzeLF/VD dzinowanzo shandiswa nejira rimwe chete rinosimudza ndiro yesimbi.Izvi zvinoreva kuti hari inofanira kunge yakareruka uye yakamanikana kupfuura hari dzeEAF/BOF kuti dzikwane mukati menzvimbo yehuni uye nzvimbo yehuku dzecrane.

5. Kemikari yeslag ndiyo inonyanya kukosha (yakakwira CaO/Al₂O₃), iyo inorwisa miganhu yesilicon nearuminiyamu.Kunyatsotarisa zvinhu zvisina simbi zvinodiwa.

Mibvunzo Inowanzo bvunzwa (Mibvunzo Inowanzo bvunzwa) - LF/VD Specific

Q: Sei huwandu hwehydrogen hwakakosha zvikuru pamapoto eslag?
A: Panguva yekubviswa kwegasi mu vacuum, hydrogen yakanyungudutswa iri musimbi inogona kupararira uye kubatanidzwazve kuita molecular hydrogen pane zvisiri zvesimbi. Izvi zvinogadzira kumanikidzwa kwemukati, zvichikonzera matumbu kana kutsemuka - dzimwe nguva zvinonzi "hydrogen flaking." Hari dzeLF/VD dzinogona kubatwa nyore nyore nekuti dzinochengetwa pasi pe vacuum kwenguva yakareba.

Mubvunzo: Unogona here kusimbisa huwandu hwehydrogen mu <1.0 ppm?
A: Ehe, asi zvinoda tsika yekunyungudutsa (vacuum induction melting kana electroslag remelting) uye inodhura zvakanyanya. Pamashandisirwo mazhinji, 1.5 ppm yakakwana.

Mubvunzo: Munopa bvunzo dze vacuum leak here?
A: Ehe, tinoita bvunzo yekubuda kwemvura nehelium kana takumbira uye tinopa chitupa zvichienderana neISO 20485. Tinovimbisa mwero wekubuda kwemvura <1×10⁻⁶ mbar·l/s.

Q: Mapoto eLF slag anofanira kutsiviwa kangani?
A: Kazhinji makore matatu kusvika mashanu ega ega, zvichienderana nemafambiro emuviri. Kushanduka kwemasero emudumbu ndicho chinhu chikuru chinotadzisa hupenyu. Kuongororwa kweUT kwegore negore kunogona kuona maburi ekutanga emasero emudumbu.

Mubvunzo: Unogona here kupa mapoto eslag nejaketi remhepo rinotonhorera?
A: Kune mashandisirwo eLF anoda kutonhora nekukurumidza tisati tashandisazve, tinogona kugadzira jekete remhepo rakabatana (ganda rekunze resimbi rine nzira dzemhepo). Izvi zvinoderedza nguva yekutonhodza kubva pamaminitsi makumi mapfumbamwe kusvika pamaminitsi makumi maviri.

Mubvunzo: Mapoto enyu eLF slag anoenderana here nemasystem ekuona slag level otomatiki?
A: Ehe. Tinopa padhi rakati sandara pamupendero weradar kana laser sensor. Neimwe nzira, tinogona kuisa thermocouples kuti tione slag layer.

Mubvunzo: Munopa kudzidziswa kwekuongorora pot yeLF here?
A: Ehe, tinopa kudzidziswa kwezuva rimwe chete panzvimbo iyi kune timu yenyu yekugadzirisa: UT ye trunnions, zvinodiwa pakuongorora nemaziso, uye nzira dzekugadzirisa cracks.

Mubvunzo: Ndeipi garandi yakajairika yeLF/VD slag pot?
A: Mwedzi makumi maviri nemana kana gumi remasekeji - chero chinenge chiri chekutanga. Pabasa rekubvisa mvura (nekuyedzwa kwekubuda kwemvura), garandi inowedzerwa kusvika kumwedzi makumi matatu nematanhatu isingatsemuke nehydrogen.
