Furnaces
We add Limestone Coke and Iron Ore to this furnace which yields either Pig Iron or Slag
BLAST FURNACE
A grey, hard, and porous fuel with a high carbon content
Coke
A semi-finished piece of metal that is rectangular or square in shape.
These are larger than Billets
Blooms
The soaking of metal in an acid to remove the hardened scale that develops from hot working.
Pickling
This type of rolling is done to make a more precise shape.
Cold Rolling
Adds pure oxygen to the bottom of the tank the furnace which is filled with Pig Iron Scrap Iron and Limestone.
Also the most common of secondary furnaces which is used to create nearly 70% of all the metal in the world.
Basic Oxygen Furnace (BOF)
A native compound from which the metal may be profitably extracted
Iron Ore
A flat, semi-finished piece of metal that is at least twice as wide as it is thick.
Slabs
A surface hardening method that heats a metal within a carbon-rich environment to increase carbon levels on the metal surface.
Carburizing
This type of Rolling is done above the critical temperature of the metal and leaves behind scale
Hot Rollled
Starts with cold metal can use Pig Iron but most commonly uses Scrap Metal
Heat Molten Metal and Limestone with Electrodes
Very Costly
Electric Arc Furnace (EAF)
Added to Coke and Iron ore this mineral helps extract the impurities.
Limestone.
A small, semi-finished piece of metal that is rectangular, circular, or square in shape.
They are smaller than Blooms.
Billets
The steady heating of a metal at a certain temperature followed by a gradual cooling process.
Annealing.
This type of Rolling results in more stress .
Cold Rolled
Often used to make specialty steels like alloy steels, tool steels, and stainless steels.
Electric Arc Furnace (EAF)
The two main products which come out of the Blast Furnace which was filled with Coke Limestone and Iron Ore
Slag( the impurities) and Pig Iron
The first solidified piece of steel from which other parts are made.
Ingots
Often done to Colled Rolled Steel to reduce the stress formed during the cold rolling
Annealing
The type of metal used in the Tap and drill Gage
Colled Rolled Steel (CRS)
Metal manufacturing has been around this long
5,000 years
The process which produces Billets Blooms and Slabs
Continuous Casting Process
This shape of this is tapered to allow the mold to be removed from the semi finished product
Ingot
Do the lack of enough carbon this process is done to allow 1018 to become hardened.
Carburizing
The first three words from the tv show Rawhide.
