Electric Arc Furnace (EAF) - HarbisonWalker International

The electric arc furnace (EAF) is the major producer of hot metal in the steel industry today. There are two types of EAFs: alternating current (AC) and direct current (DC). AC EAFs have three electrodes, while DC EAFs have two: a cathode, which is a single electrode in the roof of the furnace, and an anode in the bottom of the furnace.

Mathematical model of magnetite oxidation in a rotary kiln

The grate-kiln taconite pellet induration system involves several stages of heat and oxygen transfer to a traveling bed of spherical taconite pellets, as shown in Figure 1. At the heart of the process is the rotary kiln where pellets are heated to temperatures in excess of 1600 K with a high temperature flame.

Taconite Iron Ore Processing: National Emission Standards for

Rule Summary. On October 30, 2003 the Environmental Protection Agency issued a final rule which includes technology-based National Emission Standards for Hazardous Air Pollutants (NESHAP) to reduce emissions of hazardous air pollutants (HAP) from taconite iron ore processing facilities. These NESHAP implement section 112 (d) of the Clean Air Act and address emissions of HAP from new and existing ore crushing and handling operations, ore dryers, indurating furnaces, and finished pellet

PDF Engineered Design of Fiber Reinforced Precast Refractory

Their taconite processing plants use heat in furnaces to oxidize and indurate iron in the final stage of making a taconite pellet. Facilities can increase efficiencies when refractory service life is maintained. Efficiencies gained include: less fuel used, better quality control, better furnace control, and less mechanical component maintenance.

The unfired taconite pellets enter the induration furnace where they are hardened and oxidized at a temperature of between 2,290 to 2,550 degrees Fahrenheit. Indurating furnaces are either straight grate furnaces or grate kiln furnaces. The hardened, finished pellets exit through the indurating furnace cooler.
