Kev Siv Hlau Hlau Siv rau EAF / LF / ARC Rauv nrog mis tshuab zoo li qub SP HP UHP Graphite Electrodes
Kev Siv Hlau Hlau Siv rau EAF / LF / ARC Rauv nrog Lub Numles: Cov Neeg Kho Tshuab Zoo Zog RP / HP / UHP Graphite Electrodes
Fais arc rauv (EAFs), leds rauv taws (LFS) RP, HP, thiab UHP cov hluav taws xob tau tsim los ua kom tau raws li cov kev xav tau no, kom ua tau zoo, kom muaj kev muaj teeb meem ib puag ncig.
Nipples are critical for connecting electrodes to furnace roofs or overhead cranes. They require electrodes with precise dimensional tolerances (±1 mm diameter) and smooth surfaces to prevent leaks or arcing. RP electrodes (75–150mm) use coarse grain structures (particle size 100–200 μm) for rigidity, while HP/UHP electrodes (200–300mm) employ finer grains (50–100 μm) for enhanced tensile strength (>12 mpa).
Mechanical zog ncaj ncaj cuam tshuam ncaj qha rau hluav taws xob electrode. Hauv EAFs, thermal expansion thiab mertaction (txog li 3 hli rau ib lub voj voog kub) kev sib ntaus sib tua hluav taws xob ntawm lub naple hlij dej. HP electrodes, nrog lawv cov roj carbon ntom ntom nti, tiv thaiv tawg hauv qab no cov rog no, txo cov zaus hloov los ntawm 20-30% piv rau cov qib qis. UHP Electrodes, txuas ntxiv tsim kho ntawm iasteratic nias, tuav txoj kev ncaj ncees txawm nyob rau {}} kev voj voog kub.
In LF refining, where electrodes remain stationary for extended periods, mechanical stability prevents "drooping"-a common issue that disrupts arc stability. HP/UHP electrodes' high modulus of elasticity (>15 GPA) Ua kom paub meej txog kev deflection tsawg, kev tswj kom muaj kev faib tawm tam sim no thiab kev sib txuam.
Txawm hais tias nyob rau EAFs Melting seem los yog LFS Refining Steel, Graphite cov hluav taws xob nrog cov mis thiab cov tshuab hluav taws xob hi {sib yeem. Lawv lub peev xwm los tiv thaiv cua sov, tshuab, thiab kev ua haujlwm hnyav ua rau lawv tus caj qaum ntawm niaj hnub steelmaking.
