Brief: This video demonstrates the setup, operation, and key moments during typical use of a 50 Ton VOD Furnace for producing super purity steel. You will see how the Vacuum Oxygen Decarburization process works in a manufacturing plant, including the refining steps for dehydrogenation, denitrification, and desulfurization to achieve ultra-low impurity levels.
Related Product Features:
  • Designed for 50 Ton Ladle Refining Furnace (LRF) applications in steel manufacturing plants.
  • Achieves super purity steel with total [H], [N], [O], [S], [P] ≤50ppm or lower through vacuum refining.
  • Strengthens argon blowing at the furnace bottom for ideal molten steel stirring and dynamic effects.
  • Capable of dehydrogenation, denitrification, desulfurization, and deoxygenation under vacuum conditions.
  • Features independent argon flow adjustment per vacuum tank for precise automatic regulation.
  • Offers two vacuum pump system options: full steam jet or steam jet + water ring for efficiency.
  • Operates at vacuum levels as low as 67Pa to ensure effective dehydrogenation requirements.
  • Provides custom solutions, professional engineering design, and comprehensive project support.
FAQs:
  • What is the primary function of the 50 Ton VOD Furnace?
    The primary function is to produce super purity steel by removing impurities like hydrogen, nitrogen, oxygen, sulfur, and phosphorus through Vacuum Oxygen Decarburization (VOD) and other refining processes, achieving levels of ≤50ppm or lower.
  • How does the VOD Furnace handle dehydrogenation and desulfurization?
    For dehydrogenation, it operates at vacuum levels as low as 67Pa to reduce hydrogen content to ≤1.5ppm. Desulfurization occurs simultaneously with deoxidation under vacuum; for ultra-low sulfur grades, specialized desulfurizers with strong sulfur affinity are used.
  • What types of vacuum pump systems are available for this furnace?
    Two series are available: a full steam jet vacuum pump system using water steam and cooling water, and a steam jet + water ring vacuum pump system that uses less steam and cooling water with minimal electricity consumption, based on extensive research and application.
  • What support and services do you offer with the VOD Furnace?
    We provide custom solutions with effective quotations, professional engineering design services, comprehensive project consultation and support, factory visit arrangements, and high-quality after-sales service to ensure optimal performance.
