From double-row pallet coil transport to cable-free self-propelled ladle cars and self-propelled steerable hot metal cars — 20 years dedicated to heavy-duty metallurgical transport equipment, driving the steel industry's transport systems from mechanization toward intelligence.
Over two decades of continuous innovation, forming a complete technology system from double-row pallet coil transport to the self-propelled steerable "one-ladle-through" hot metal car, advancing metallurgical transport equipment from mechanization to intelligence.
A revolutionary replacement for conventional transport chains. The double-row pallet cars enable flexible transport of coils between hot rolling, cold rolling and finished-product warehouses, greatly reducing coil surface damage and improving logistics efficiency. This technology has been a mainstream solution for hot rolling lines worldwide since 2010, earning the Metallurgical Science and Technology Award and national invention patent authorization.
Coil Transport Metallurgical Science & Technology AwardUses a moving power supply to energize coil transport vehicles, eliminating the safety hazards of conventional sliding contact lines. However, this technology demands stringent working conditions and its power supply is limited, making it less suitable for high-intensity transport demands.
Wireless Power Specific Operating Conditions Supports High-End Silicon Steel ProductionReplaces conventional batteries and cable reels with supercapacitors — fast charging, long service life and maintenance-free, achieving a green energy upgrade for metallurgical transport equipment. Holds international patents (US, EU, KR), was selected for the Top 10 World Steel Technology News, listed in the Hebei Province Extreme Energy Efficiency Recommended Equipment Catalog, led the industry standard JB/T 14908-2024, and won the Metallurgical Science and Technology Award.
International Patents Industry Standard Top 10 News Metallurgical Science & Technology AwardPowered by supercapacitors, this design eliminates conventional cable reels and sliding contact lines, enabling cable-free self-propelled operation of the ladle transfer car. The 220-tonne-class car has completed engineering validation with 896 heats and 197,000 tonnes of molten steel transported, with zero safety incidents. The car requires a turntable for direction changes.
Cable-Free Engineering ValidatedAchieves direct transport of hot metal from blast furnace to converter, eliminating the reladling step and reducing temperature drop and energy consumption, driving the restructuring of the ironmaking-steelmaking interface process. Independently mobile and steerable, it realizes the "one-ladle-through" direct-delivery mode.
