Pyrite for Blast Furnace Feeding

Specifications: Sulfur 49% | Size 1-5cm Lump Pyrite

Core Chemical Index

• Total Sulfur (S): 49% Standard Stable Content
• Ferrous Content: 43% Min
• Moisture: ≤0.5%
• Harmful Impurity: Phosphorus ≤0.005%, Arsenic ≤0.02%
• Particle Size: Uniform 1-5cm lump, size pass rate ≥95%
• Melting Characteristic: Stable decomposition under high smelting temperature

Unique Advantage of 49% Sulfur + 1-5cm Size

1. High sulfur concentration, less dosage & lower cost49% high sulfur content ensures sufficient effective sulfur element, lower adding proportion in steelmaking, effectively reduce overall raw material consumption and production cost.
2. 1-5cm lump size fits blast furnace feeding perfectlyStandard lump size will not block conveyor and feeding equipment, free of flying dust and material loss during conveying and feeding. It can mix evenly with iron ore, coke and flux without grading segregation, stable feeding volume and easy automatic batching control.
3. Slow and uniform high-temperature sulfur releaseCompared with fine powder and oversized bulk ore, 1-5cm pyrite decomposes steadily inside blast furnace, 49% sulfur releases evenly and continuously, avoid instant sulfur surge or insufficient sulfur supply, greatly stabilize molten steel internal composition.

Main Functions in Steelmaking & Blast Furnace Smelting

1. Precisely adjust sulfur content of molten steelStable 49% sulfur element can accurately control target sulfur range of finished steel, meet production standard requirements of free cutting steel, cast steel and ordinary carbon steel, optimize steel internal structure.
2. Improve cutting performance of finished steelAppropriate sulfur component formed by pyrite decomposition can reduce cutting resistance of steel material, lower tool abrasion, promote smooth chip breaking, obviously upgrade machining efficiency and finished workpiece surface finish.
3. Optimize slag fluidity inside furnaceEffective sulfur composition improves slag activity and flow property during smelting, accelerate separation of slag and iron, reduce smelting dead time, raise molten iron yield and blast furnace operating efficiency.
4. Assist heat balance inside blast furnacePyrite releases certain heat in high-temperature reaction process, auxiliary balance furnace internal temperature field, reduce coke unit consumption, realize energy saving and consumption reduction in long-term production.
5. Restrain steel internal defectLow phosphorus and low arsenic impurity formula match 49% high-purity sulfur, avoid hot brittleness and cold brittleness of steel, enhance finished steel texture uniformity and overall mechanical stability.

Application Scope

Mainly used for blast furnace burden blending, electric furnace steelmaking sulfur adjustment, ductile iron / gray cast iron smelting, mechanical free-cutting steel raw material allocation, widely applicable to medium and large iron and steel smelting enterprises.
