CHARGE: To load a furnace with scrap and flux prior to melting, or to load a soaking pit with ingots for reheating.
CHE M IS T RY : The chemical constituents of a heat of steel.
CONTINUOUS CASTER: A machine used to continuously produce blooms from molten steel with no interruptions or intermediபைடு நூலகம்te operations.
CREEP: Failure of a metal caused by gradual elongation due to constant stress.

----A back to top ----A DDIT IO NS : Materials, typically alloy elements, added to molten steel to produce the chemical specifications for the desired steel grade. ALLOY: A substance that has metallic properties and is comprised of two or more chemical elements of which at least one is a metal.
DE O X IDIZ E : Removal of oxygen from steel.
DIF F US IO N: Movement of atoms in solids. Heat provides the energy for atom movement.
DRAW: To empty a soaking pit one ingot at a time to feed rolling operations (FSP), or to pull steel (usually cold) through a die to change its dimensions and mechanical properties.
BLOOM: A semi finished piece of steel resulting from the rolling or forging of an ingot. A bloom is square or not more than twice as wide as thick and usually not less than 36 square inches in cross-sectional area.

COLD WORKING: Rolling or drawing semi-finished steel products to provide higher physical properties or better surfaces than can be produced by hot-working.
ELECTRIC ARC FURNACE (EAF): A refractory-lined steel vessel used to melt steel. An electric arc generates the heat.
A NNE A LING : A process involving heating and cooling, usually applied to induce softening of steel. The term also refers to treatments intended to alter mechanical or physical properties, produce a definite microstructure or remove gasses.
BOTTOM POURING: The process of pouring ingots using a refractory runner system to fill them from the bottom of the ingot molds.
BREAKOUT: Liquid steel flowing through the shell of a ladle or EAF.
CA S T ING : Pouring molten metal into a mold, or the metal object (i.e., ingot) produced by such pouring.
CASTING POWDER: A powder applied to the inside of a mold before teeming to prevent the metal from sticking to the mold.
BLOOM SHEAR: A shear used to cut a rolled ingot into shorter bloom lengths or to cut off the ends of a bloom.
BLOWHOLE: An internal cavity in steel produced by gases during the solidification of the metal.
CRYSTAL: Physically uniform solids composed of atoms bonded together in a definite geometrical pattern or structure.
CRITICAL TEMPERATURE: The temperature at which a steel transforms one crystal structure into another because of atom rearrangement.
ARGON SHROUD: A procedure using argon gas to shield molten steel from oxygen as it is teemed from the ladle.
ARGON STIRRING: An inert gas introduced through a nozzle to stir molten steel to promote chemical and temperature homogenization and float out inclusions.
BUTT: An unfinished or incomplete ingot. ----C back to top -----

CA RB IDE : A compound of iron (or other element) and carbon in steel, forming a very hard, nonmetallic substance (Fe3C). Fe3C is also called cementite.
BRINNEL HARDNESS: A hardness test commonly used for soft steel and metals which measures diameter of an indentation made by a steel ball under a given load.
A US T E NIT E : High-temperature solid form of steel with face-centered cubic crystal structure.
----B back to top ----B ILLE T : A semi-finished piece of steel that results from rolling an ingot or a bloom. It may be square but is never more than twice as wide as thick. Its cross-sectional area is usually not more than 36 square inches.
ALLOY STEEL: Steel containing one or more alloying element. Steel is classified as alloy when the maximum content of alloying elements exceeds one or more of the following: manganese 1.65%, silicon 0.60%, copper 0.60%.
DUCT ILIT Y : Ability to undergo permanent changes of shape without rupturing. ----E back to top ----ELASTIC DEFORMATION: Temporary distortion of a material under the action of applied stresses.
