| EAF |
Electric Arc Furnace |
| Eddy Current Separator |
A device for separating nonferrous metals from nonmetallic material that works by creating a mechanically driven rotating or alternating magnetic field and moving a non-magnetic metallic particle into this field. An eddy current is created in the particle, producing a magnetic field with a like polarity, and ejecting it from the fixed field generator.
|
| Eddy Current Separators |
(or ECS for short) separate non-ferrous metals from waste by generating a strong oscillating magnetic field. The magnetic field changes 10,000 times per minute from north to south causing non-ferrous metals to jump. Eddy currents do not work on Stainless Steel and are easily damaged by ferrous metals.

| Effective Date |
As here defined, this item referes to pricing, and more specifically to a price quoted in a trade paper or magazine, (AMM-Iron Age). As opposed to the terms "cover date" or "issue date," the "effective date" usually is synonymous with the term "price page date," and is usually earlier than the issue or cover date. Since the term "effective date" as so many implications, it should be avoided in favor of "price page date" and should not be used in connection with "cover date" or "issue date."
|
| Electric Air ( Furnace) |
A melting facility whose heat is the result of an electrical charge of great intensity passing between two graphite electrodes.
|
| Electric Arc Furnace |
Steelmaking furnace where scrap is generally 100% of the charge. Heat is supplied from electricity that arcs from the graphite electrodes to the metal bath. Furnaces may be either an alternating current (AC) or direct current (DC). DC units consume less energy and fewer electrodes, but they are more expensive. |
| Electric Furnace |
Any of a variety of melting facilities whose essential heating source is electrial power. There are a variety of types, arc, and induction.
|
| Electrical Steel |
Steel that includes silicon. The silicon content allows the steel to minimize energy loss during electrical applications. |
| Electrostatic separator |
Use high voltage (10,000 volts DC) to separate conducting from non-conducting materials, i.e., copper wire from plastic wire insulation.
|
| Elements |
Except for pure iron, which contains 100% of the element iron, all other iron and steel products contain other alloying "elements." Each element imparts to the product to which it has been added certain characteristics which are either desirable or undesirable for various purposes. A knowledge of the most frequently used elements in iron and steelmaking is of great value for a scrap trader. The correct chemical abbreviations for each of the frequently used elements should be a part of each trader's knowledge. (See Mendeleef's "Chart of the Elements" in any good chemisty text book.) |
