Cov hluav taws xob en graphite rau arc rauv

Graphite cov khoom lag luam electrode

Electrodes ci ntawm graphite ("en graphite" hauv Fab Kis, lub ntsiab lus yog qhov tsis muaj zog ntawm cov hluav taws xob ua kom muaj zog rau hauv qhov khaus hluav taws xob. Cov hluav taws xob no tau tsim los tiv thaiv cov mob eaf heev ntawm Eascaking ntau dua 3000, thiab faib khoom cua sov, thiab nws tsis sib luag.

​Cov kev siv hauv arc rauv​

Graphite electrodes nyob rau hauv EAFs Ua Peb Qhov Tseem Ceeb:

​ARC Qhov pib & txij nkawm: Cov duab graphite, txo qis rau hauv cov cub hluav taws xob, pib muaj hluav taws xob arc (ionized ntshav) ntawm nws tus kheej thiab tus hlau, dri, lossis hlau, lossis cov hlau kub). Qhov ANC tsim 3,000 Qib + + Tshav Kub Kub, Melting 50-300-Tuj SCRAP raug nplua hauv 40-90 feeb. Rau cov EAF loj (200+ }- tons), 600-7 electrodes tswj cov arcs ruaj khov ntau txawm scraps loj.

​Thaum Tshav Kub Kub Hloov & Da Dej Kev Cai: Graphite lub siab thermal conductivity (110-150 W / min k · k · k · k · k · across hla ntawm molten da dej, tiv thaiv cov me nyuam txias thiab nrawm thiab nrawm melting. Tapered Profiles (1-2 Degree Shaling) Ua kom zoo faib cov khoom xa tuaj tam sim no, kev txo qis kev yaig thiab hluav taws xob pov tseg.

​Metallurgical feem ntau: Tam sim no ntws induces electromagnetic stirring, txhim kho kev sib xyaw ntawm Molten hlau thiab swb. Qhov kev ua kom nrawm nrawm cov tshuaj tiv thaiv zoo li desulfurization (cao hauv s hauv steel), depusion kev tshem tawm, thiab kev cais tawm rau kev tsim cov high- zoo steel.

​Cov khoom siv tsim & Tsim qauv​

​Graphite purity​: High-purity graphite (carbon content >99.5%, Tshauv<0.5%) ensures low resistivity (15–25 μΩ·m) and minimal metal contamination.

​Neeg Kho Tshuab Muaj Zog​: Compressive strength >70 MPa and flexural strength >25 MPA FROWND TEEB TUB KUB (txog 6 Electrodes, 3 meters ntev) thiab Arc - induced kev ntxhov siab.

​Thermal ruaj khov: Tsawg thermal expansion (2-4 × 10⁻⁶ / degree) tiv thaiv sab nraud nyob rau hauv cov cua sov / cua txias cycles, lub neej pabcuam kev pabcuam sai.
