Tukunyar LF/VD | Ladle Fired Akwatin Slag na Musamman don Aikin Karfe na Biyu - Womic Steel

Takaitaccen Bayani:

Girman Tukunyar Slag:Ƙarfin tan 5 - 40 (ya yi daidai da girman LF na yau da kullun), nauyi tan 8 - 45, girma 4 - 25 m³, girma dabam dabam da aka keɓance don dandamalin aiki na murhun ladle da ƙofar slag. Trunnion: ƙira mai ƙarancin fasali tare da daidaitawa don share ladle harbor.

Kayan Aiki & Ma'auni:ZG270-500+ (S≤0.012%, P≤0.015%), GS-20Mn5V (tare da vanadium), ASTM A27 65-35 ƙarancin hydrogen. Ya dace da ASTM A27, DIN 17182, EN 10293, ISO 3755. Maganin zafi: An kashe + An rage zafi + an cire hydrogenation. Fuskar: ciki tare da santsi mai santsi don taimakawa kwararar slag na roba, waje tare da babban murfin fitarwa don sanyaya radiation.

Tsarin Masana'antu:Haɗin siminti ɗaya tare da kulawa ta musamman ga matsewar iskar gas don ayyukan VD. EAF + LF + VD + tsawaitawar cire gas (H < 1.5ppm). Kwaikwayon ruwan zafi na CAE don zubar da slag. 100% NDT: Cikakken girma na UT (Mataki na 1 na trunnion, Jikin Mataki na 2), MT, PT, da gwajin zubar da helium don sabis na injin tsotsa.

Amfani da Tukunyar Slag:Ma'aunin slag na roba na mashin (LF), tarin slag na VD/VOD, jigilar slag na ladle daga tashar ƙarfe ta biyu, tace ƙarfe na ƙarfe, masana'antun ƙarfe na musamman (ƙarfe mai ɗaukar kaya, ƙarfen bututu, ƙarfe na bazara), riƙe slag na bakin ƙarfe na AOD, haɗakar tsarin gano slag.

T: Me yasa sinadarin hydrogen yake da matukar muhimmanci ga tukwanen da aka yi da tarkace?
A: A lokacin cire iskar gas daga injin, hydrogen da aka narkar a cikin simintin ƙarfe na iya yaɗuwa ya sake haɗuwa zuwa hydrogen na kwayoyin halitta a cikin abubuwan da ba na ƙarfe ba. Wannan yana haifar da matsin lamba na ciki, wanda ke haifar da ƙura ko fashewa - wani lokacin ana kiransa "fashewar hydrogen." Tukwanen LF/VD suna da sauƙin kamuwa saboda ana riƙe su a ƙarƙashin injin na tsawon lokaci.

T: Za ku iya tabbatar da cewa sinadarin hydrogen ya kai <1.0 ppm?
A: Eh, amma yana buƙatar aikin narkewa na musamman (narkewar injin ko sake narkewar electroslag) kuma yana da tsada sosai. Ga yawancin aikace-aikacen, 1.5 ppm ya isa.

Tambaya: Shin kuna bayar da gwajin zubar da ruwa na injin?
A: Eh, muna yin gwajin zubar da ruwan helium idan an buƙata kuma muna bayar da takardar shaida bisa ga ISO 20485. Muna ba da garantin ƙimar zubar da ruwan <1×10⁻⁶ mbar·l/s.

T: Sau nawa ya kamata a maye gurbin tukwanen LF?
A: Yawanci kowace shekara 3-5, ya danganta da zagayowar. Nakasar da ke rarrafe ita ce babban abin da ke rage tsawon rai. Duba UT na shekara-shekara na iya gano ramukan da suka fara rarrafe.
