Title: HP Graphite Electrodes | High-Current Efficiency for Mid-Scale Steelmaking

Why Mid-Sized Steel Mills from Egypt to Mexico Upgrade to HP Electrodes

HP (High Power) graphite electrodes strike the perfect balance between cost and performance. When a Colombian mini-mill aims to boost melt rates by 20% or a Malaysian foundry needs to cut electrode consumption by 15%, these electrodes deliver. Designed for 50-100 ton electric arc furnaces (EAFs), they handle intense thermal cycling without the premium price tag of UHP grades.

Key Features That Maximize ROI

Thermal Shock Resistance: Survives rapid temperature swings from 800°C to 1,800°C. A Turkish steel plant achieved 1,200+ heats with HP 550mm electrodes in scrap-heavy operations.
Optimized Current Density: 22-26 A/cm² capacity reduces tap-to-tap time by 6-8 minutes per cycle.
Anti-Oxidation Coating: Two-layer impregnation slashes sidewall consumption by 10-14% in humid environments.
Simplified Maintenance: Standardized nipple design compatible with most EAF clamping systems.
Traceable Quality: Laser-marked batch codes align with mill audit requirements.

Technical Specs for Demanding Operations

Grades & Applications:

HP 550mm: For 50-80 ton EAFs producing rebar, sections, and wire rod.
HP 600mm: Upgraded version for 80-100 ton furnaces. Used in Thai billet production.
Custom Tips: Optional threaded ends for ladle furnace refining.

Critical Parameters:

Property	HP 550mm	HP 600mm
Resistivity (μΩ·m)	6.8-7.5	6.5-7.0
Flexural Strength (MPa)	11.0-12.5	11.5-13.0
Ash Content (%)	≤0.4	≤0.35
CTE (×10⁻⁶/°C)	1.5-1.8	1.4-1.7

Packaging:

15 electrodes/steel-reinforced wooden crate
Moisture-resistant wrapping for tropical climates

Proven in 1,700°C Crucibles

Case 1: Pakistani Steel Recycler
Problem: Competitor electrodes cracked after 60 heats in a 60-ton EAF.
Our Fix: HP 550mm with upgraded joints. Achieved 140 heats at 1.5% consumption.

Case 2: Peruvian Foundry
Issue: Excessive oxidation in coastal humidity doubled costs.
Solution: Anti-oxidation HP 600mm + storage dehumidifiers. Cut waste by 18%.

Furnace Operator’s Toolkit

Installation: Apply graphite paste to nipple threads—a Vietnamese mill reduced joint failures by 30%.
Scrap Prep: Remove copper-heavy materials. An Indonesian plant lowered resistivity variance by 12%.
Storage: Keep crates under 35°C. Nigerian clients use shaded warehouses to prevent warping.
