Specialty Alloy Powder Pilot Production/Validation Technology Platform

■ Technology

  ▶ Through alloy material design and fabrication, atmosphere control, powder particle size

     control, and granulation control technologies, achieve the preparation of highly flowable

     alloy powders, enhance powder sphericity and packing density, reduce shrinkage of the

     alloy after sintering, and maintain product precision.

  ▶ For different powder forming and subsequent processing technologies, provide powder

     morphologies suitable for each process, establish process parameters, and conduct

     microstructure analysis, physical property analysis, and mechanical property analysis to

     determine optimal process parameters.

  ▶ Provide a comprehensive solution for pre-production specialty alloy powder design and

     development, high-quality powder production, powder particle size control, process

     parameter development, and powder material performance validation.

Permanent Magnet Powder Development Trial Production Technology

■ Technology

  ▶ By controlling alloy composition and impurities, the powder particle size, crystalline

     properties, and grain size are managed. Melt-quenching technology boosts the alloy’s

     cooling rate for finer grains. A gas guidance system and copper wheel cooling design

     further increase cooling speed.

  ▶ A high-performance rare earth permanent magnet powder production technology,including

     a system for unidirectional fine-grain magnetic flakes, a hydrogen decrepitation(HDDR)

     system,and a jet milling system is established. The flake production system creates

     Nd₂Fe₁₄B magnetic flakes with strong C-axis alignment, about 200 μm thick. After

     hydrogen decrepitation and jet milling, the rare earth alloy powder reaches a D₅₀ particle

     size of around 2 μm.

Electric Arc Furnace Low-carbon Technology Development Validation Platform

■ Technology

  ▶ Develop①foam slag technology, where fine foam enhances insulation and reduces heat loss;

     ②low-carbon model design, optimizing input material ratios and processes to reduce carbon

     emissions.Integrate these two technologies to address the primary cause of steelmaking

     carbon emissions—energy loss.

  ▶ Create a 0.2-ton experimental electric arc furnace smelting system and verification platform to

     perform initial evaluations of low-carbon smelting processes, assisting the domestic electric

     furnace industry in developing low-carbon smelting technologies.

 

■ Technical Capabilities and Equipment

 

 

■ Application

Develop near-real simulation technology for low-carbon steel reactions without altering existing equipment of domestic steelmakers, establish low-carbon steel smelting and forming technologies using a 0.2-ton electric furnace platform to optimize raw material carbon content and adopt low-carbon reduced iron, reducing emissions without changing existing equipment.
