Semi-Solid Forming Materials and Processing Technology for Aluminum Alloys
■ Features
▶ Semi-solid forming improves coarse microstructure and shrinkage defects found in conventional
liquid casting, resulting in mechanical properties close to forged parts
▶ The Materials and Chemical Research Laboratories have conducted semi-solid aluminum
forming research for over ten years and developed patented technologies for spheroidized
semi-solid materials and equipment
▶ Customized alloy design and casting process development are available, including weldable,
heat-treatable, or anodizable technologies
■ Market / Applications
▶ High-strength structural components for electric vehicles, motorcycles, e-bikes, and lightweight
mobility systems
▶ Complex housing structures requiring high thermal conductivity or airtightness
High-Performance Cu-Ag Alloys/Cu-Graphene Composite Processing Technology
■ Features
▶ After optimization of composition and process, Cu-Ag alloy and Cu-graphene composite
materials possess both high electrical conductivity and high strength.
▶ Using hot-mold continuous casting enables net-shape formation of wires, bars, and tubes
with uniform properties. It is a key technology for developing and producing ultra-fine,
bend-resistant or thin-walled tubular products.
■ Market / Applications
▶ Thin heat pipes are mainstream thermal solutions for 5G mobile & notebooks.
▶ High-fidelity, fold-resistant signal transmission cables for intelligent machinery and medical
instruments.
High-Efficiency Fluidized-Bed Hydrogen Direct Reduction Iron Technology
■ Technical Overview
▶ Traditional blast furnace ironmaking technology generates a large amount of carbon emissions(1.6
tCO2e/t-Steel), However, the hydrogen-based direct reduction of iron technology, with its main
chemical reaction of Fe2O3+3H2 → 2Fe+3H2O, produces no direct carbon emissions
▶ The reduction of iron oxide is carried out using fluidized bed technology. The fluidized bed causes
iron oxide particles to flow and collide with each other, generating dynamic mixing and avoiding dead
zones in the reaction, thereby improving heat and mass transfer, and enhancing the reaction rate and
temperature uniformity
■ Features
▶ The system allows for real-time measurement of iron oxide weight loss within the fluidized bed and
the instantaneous pressure difference within the reaction chamber during fluidization, enabling
monitoring of the fluidization state within the reaction chamber.
▶ Hydrogen reduction reaction concentration range: 0~100%.
■ Achievements
▶ A 500g-level verification device can instantly confirm the reduction rate of raw materials, currently
reaching 93%. A 25kg-level demonstration production device can produce small quantities of reduced
iron for verification purposes in replacing pig iron and scrap steel.
▶ It can already reduce rust produced in electric arc furnace processes; XRD analysis confirms that it
can reduce iron oxide to iron.
▶ The self-made direct reduced iron has been hot-pressed into blocks for easy input into electric arc
furnaces or blast furnaces.
