Product Overview

Our petroleum coke-based carburizer is a high-efficiency, low-sulfur carbon additive specially designed for the foundry and steelmaking industries. Made from premium petroleum coke through high-temperature calcination and refining, it features high carbon content, low impurities, and excellent absorption rates, significantly enhancing the carbon content of molten iron/steel, improving metal properties, and reducing production costs.

Key Advantages

✅ Ultra-High Carbon Content (≥98%)

Ensures stable carburization effects, reduces dosage, and lowers costs.

✅ Ultra-Low Sulfur (≤0.5%)

Prevents sulfur-induced brittleness in castings, improving product quality.

✅ High Absorption Rate (85%~95%)

Uniform particle size, fast dissolution, and efficient carbon absorption minimize waste.

✅ Low Ash Content (≤1%)

Reduces slag formation, extends furnace lining life, and lowers cleaning costs.

✅ Multiple Particle Sizes Available (0.5-10mm)

Suitable for various melting equipment, including induction furnaces, electric arc furnaces, and cupolas.

Typical Applications

Foundry Industry: Adjusting carbon content in ductile iron, gray iron, and compacted graphite iron.

Steelmaking Industry: Carbon compensation in electric arc furnaces (EAF) and medium-frequency furnaces.

Precision Castings: High-quality applications such as automotive parts and machined components.

Technical Specifications
