Product Introduction

Product Advantages

1. High Carbon, Low Sulfur, and Low Nitrogen

Fixed carbon content reaches 98.5%–99.5%, with sulfur as low as 0.03%–0.05% and nitrogen at 200–300 ppm, meeting the stringent impurity requirements of high-end iron and steel smelting.

2. High Absorption Rate and Effective Carburization

Graphitization arranges carbon atoms in an orderly graphite structure, ensuring rapid dissolution in molten iron or steel. Absorption rates reach 90%–95%, providing stable carburization without slag reversion.

3. Improved Casting Quality

High graphite nucleation and graphitization levels reduce shrinkage tendencies in molten iron and enhance mechanical properties. In ductile iron, it increases ferrite content by 10%–15% and boosts the graphite nodule count by 400%.

4. Cost Reduction

Using graphitized petroleum coke as a recarburizer allows for a significant increase in scrap steel usage and a reduction-or even elimination-of pig iron, effectively lowering raw material costs.

5. Furnace Lining Protection and Extended Service Life

Stable carburization and high absorption rates minimize slag formation, effectively protecting the furnace lining and extending its service life.

Application Areas

1. Iron and Steel Smelting (Core Application): As a premium recarburizer, it is widely used to adjust carbon content during electric arc furnace steelmaking, induction furnace melting, and refining processes for the production of high-quality, special, and alloy steels.
2. Foundry Industry: Used in the production of ductile iron, compacted graphite iron, and gray iron castings. Selecting high-carbon, low-sulfur graphitized products for ductile iron smelting effectively improves graphite morphology and enhances the mechanical properties of castings.
3. New Energy Sector: Serves as a raw material for lithium-ion battery anodes; its low thermal expansion coefficient, low impurity content, and high electrical conductivity make it an excellent precursor for anode materials.
4. Chemical Industry and Friction Materials: Acts as a reducing agent in the smelting of metals such as titanium and antimony, replacing a portion of coke while reducing sulfur and nitrogen impurities; its high thermal conductivity and wear resistance make it suitable for manufacturing friction materials like brake pads.
