A groundbreaking invention which is steering a greener future for arc furnace steelmaking is winning order after order for the CISDI Electric Furnace Institute.

The latest will see the Institute supply its green, intelligent electric arc furnace CISDI-AutoARC^TM to Du Gang Steel Co., part of the Sichuan Local Metallurgical Holding Group.

CISDI-AutoARC^TM is a world first – it charges scraps cascade-wise, horizontally and continuously, and preheats scraps during the charging process. It features a flat-bath melting and meets China’s ultra-low emissions standards.

This energy-efficient, ultra-reliable electric arc furnace is fast-becoming a core product relied on by steel enterprises aiming to boost their competitiveness.

The critical tech behind the invention has been awarded a silver medal in China’s scientific and technological advancements awards.

Its multiple breakthroughs in process, equipment, product quality and environmental protection bring significant solutions to the problems experienced with conventional EAFs melting with 100 per cent scraps - namely high energy consumption, unstable quality and dioxin pollution.

CISDI-AutoARC^TM is already operating for MCC-SFRE’s 70-tonne EAF.

Teams from CISDI EFI and Du Gang are pictured signing the CISDI-AutoARC^TM supply contract
