EAF va LF pechlarida ishlatiladigan grafit elektrodlari uchun qanday muhim xususiyatlar mavjud?

EAF va LF operatsiyalari uchun grafit elektrodlarini tanlash Har bir pechning talablariga moslashtirilgan texnik xususiyatlarga diqqat bilan e'tiborni talab qiladi:

Joriy - Yuk ko'tarishi (darcha): EAFs, especially large-scale ones, demand electrodes with high ampacity (eg, Ultra-High Power (UHP) electrodes rated for 50–70 kA) to sustain intense arcs. LFS, pastki, ammo doimiy oqimlarda ishlaydigan (odatda 10-30 ka), haddan tashqari qizib ketmasdan barqaror isitishni davom ettirish uchun doimiy isitish qobiliyatiga ega bo'lgan elektrodlarni talab qiladi.

Elektrga chidamlilik: Quyi chidamlilik energiya yo'qotishini minimallashtiradi. EAF elektrodlari past chidamlilikni moslashtirish (masalan,<55 μΩ·m for UHP grades) to maximize power transfer, while LF electrodes balance resistivity with thermal conductivity to ensure efficient Joule heating.

Oksidlanish qarshilik: Ovqatlanish muhiti (1,000-1,600 daraja) pechning uzaytirilishi oksidlanishni tezlashtiradi. Yuqori - poklik grafiti (kul miqdori)<0.5%) with dense microstructures resists oxidation better, extending service life in both EAFs and LFs.

Mexanik kuch: EAF electrodes endure dynamic stress from arc impingement, thermal expansion/contraction, and handling, requiring high flexural strength (>15 MPa) to prevent breakage. LFs, with gentler thermal cycles, still need sufficient tensile strength (>10 MPA) kiritish / olib tashlash paytida yorilishdan saqlanish uchun.

Zarrachalar hajmi va grafitizatsiya darajasi: Finer particle sizes (e.g., 15–25 mm for UHP) improve density and strength, while high graphitization (degree >90%) ikkala EAFS (ARC barqarorlik) va LFS (harorat bir xilligi) uchun muhim va issiqlik shokka chidamliligini kuchaytiradi.
