Metals, Steelmaking & Heavy Manufacturing Gas Solutions Industrial Gas Solutions
High-volume industrial gas solutions for Basic Oxygen Furnaces (BOF), Electric Arc Furnaces (EAF), fiber laser cutting assist gas, and robotic welding shielding across steel mills and fabrication hubs.
Edge Oxidation, Slag Inclusions, Weld Porosity & Furnace Energy Costs
Steel mills and fabrication facilities face tough operational hurdles: slow cutting speeds with heavy oxidation scale requiring expensive manual grinding, high fuel costs in un-enriched melting furnaces, and atmospheric nitrogen/hydrogen pickup causing embrittlement in molten steel. Shakti Group supplies bulk Liquid Oxygen (LOX) for blast furnace combustion enrichment and decarburization, ultra-pure Liquid Argon (LAR) for ladle furnace bottom stirring and degassing, and high-pressure Liquid Nitrogen (LIN) skids delivering continuous 25-30 bar assist gas for fiber laser cutting.
Primary Process Applications
Core gas applications for Metals, Steelmaking & Heavy Manufacturing Gas Solutions:
- Steelmaking & Electric Arc Furnace (EAF / BOF) Decarburization (Liquid Oxygen (LOX) & Argon (LAR), ≥ 99.5% LOX / ≥ 99.999% LAR Grade 5.0): Oxygen is lanced into blast furnaces and BOF converters for fast carbon burn-off. Argon is injected through bottom porous plugs for ladle stirring, temperature homogenization, and desulfurization.
- Fiber Laser Cutting Assist Gas (25 - 35 Bar) (High-Pressure Liquid Nitrogen (LIN), ≥ 99.999% Grade 5.0 (Moisture < 2 ppm, O₂ < 2 ppm)): Blasts away molten stainless steel and aluminum kerf at high pressure, yielding dross-free, oxide-free edges without post-cut processing.
- TIG & Robotic MIG Arc Welding Shielding (Pure Argon (LAR) & Ar/CO₂ Welding Mixtures, ≥ 99.99% to 99.999%): Shields molten weld pools from atmospheric oxygen and nitrogen, preventing joint porosity, spatter, and oxidation in critical pressure vessels and structural steel.
- Bright Annealing & Heat Treatment Atmospheres (Nitrogen (N₂) + Hydrogen (H₂) Gas Blends, Grade 5.0 High Purity): Provides a reducing, protective atmosphere in bell and continuous annealing furnaces to prevent surface decarburization and scaling on cold-rolled steel coils.
