2025年2月11日 · Last month, we successfully completed our duct system connecting our Electric Arc Furnace (EAF) building to our Fume Treatment Plant. Our duct system wraps around the building to capture particulate emissions and channel them directly to the treatment facility, reducing our environmental footprint.

Learn how Spray-Cooled™ technology decreases furnace maintenance costs while increasing reliability. One-piece construction and dual containment capabilities make Systems Spray-Cooled™ EAF off-gas ductwork the greenest choice available.

SMS Siemag developed a new type of electric arc furnace – the steady EAF (S/EAF) – that is most efficient for the continuous charging of DRI. With this solution, the idea of a continuously operated EAF turns into reality.

These unusually long maintenance fee operational lifetimes make EAF water-cooled ducts and BOF water-cooled hoods fabricated from WSI’s patented Unifuse Alloy 625 Weld Metal Overlay process the lowest cost solution based on equipment replacement costs alone.

The water-cooled duct is sometimes sized larger than the elbow so that efficient capture can still be achieved even when the furnace is tilted 65°. One of the more recent innovations is to use a very steep elbow config-uration which will help to reduce slag buildup.

Off-gas measurements in the primary exhausting duct are difficult due to high gas temperatures and the presence of dust. The adjustment of the exhausting system is often empirically determined or...

Electric arc furnaces use iron scrap as a major iron component in the manufacture of steel primarily used in construction industry. In most advanced countries EAFs produce 30–35% of total steel production.

The SmartFurnace EAF Optimization system consists of a series of interacting entities. The DigitARC PX3 electrode regulator, together with the electrical and chemical energy supervisory control application, provide an integral optimization solution of the furnace operation parameters,

In our paper, we will describe the method of improving energy efficiency by the utilization of waste heat in the off gas generated in EAF and introduce ECOARCTMs under commercial operation.

JP Steel Plantech Co. has developed Hybrid system for EAF off-gas heat recovery, with EAF boiler and Waste Heat Recovery Boiler (WHRB) with duct burner installed in series to make the most of EAF off-gas heat available. Off gas heat energy discharged from EAF accounts 40% of …
