With the accelerated low-carbon upgrading of the metallurgical industry, electric arc furnaces (EAFs) have become the mainstream equipment for short-process steelmaking, thanks to their advantages of short process flow, flexible commissioning and low carbon emissions. The new-generation intelligent electric arc furnace is equipped with scrap preheating, flue gas waste heat recovery and an intelligent electrode regulation system. It is suitable for smelting carbon steel, special steel and alloy steel, and is widely used in recycled steel smelting projects. It serves as a preferred solution for steel mills to reduce carbon emissions, control costs and realize flexible production.
Against the backdrop of green upgrading in the metallurgical industry, short-process EAF steelmaking is embracing rapid development opportunities. Unlike the traditional long-process route of blast furnace plus basic oxygen furnace, the electric arc furnace mainly uses scrap steel as raw material and melts and refines scrap by electric energy, eliminating the blast furnace ironmaking stage and delivering outstanding carbon emission reduction benefits.
The new-generation high-efficiency electric arc furnace integrates a number of mature domestic metallurgical technologies. It adopts continuous charging and scrap preheating processes to effectively improve heat utilization and reduce power consumption per ton of steel. Combined with intelligent electrode control, furnace gas comprehensive treatment and waste heat recovery systems, it limits emissions of dust and other pollutants to meet ultra-low emission standards. Featuring flexible start-up and shutdown, the equipment can quickly adjust production capacity according to order requirements. It is ideal for smelting multi-variety, small-batch special steel, and is widely applied in special steel, casting and recycled steel projects.
Domestic EAF equipment keeps evolving toward large-scale design, digitalization and clean smelting. Technologies including DC power supply, combined blowing, automatic temperature measurement and sampling are continuously maturing, which steadily improve smelting stability and molten steel cleanliness. When supported by green power, electric arc furnaces can achieve further deep carbon reduction, in line with the low-carbon transformation demands of the global metallurgical sector.
At present, many steel mills at home and abroad are promoting production capacity structure optimization. Short-process electric arc furnace projects keep being launched, and market demand grows steadily. We can supply complete sets of electric arc furnaces of various tonnages, matching ladle refining furnaces, dust removal systems and supporting engineering solutions.
