You need more than Iron? Why coke is used…
1. Generates high heat, needed in order for chemical reactions in ironmaking to take place.
2. Produces CO (carbon monoxide) which reduces
iron-oxide to Iron.
(Same height as a 10 story building)
Uses a fuel to generate heat, and melt the metal.
-Molten metal skips ingot step, and goes directly the furnace to a “tundish”
-Metal solidifies in the mold
-The metal descends @ about 1”/sec
-The solidified metal then goes through
‘pinch rollers’ that determine the final
Carbon and Alloying Steel
Tool and Die Steels
High Carbon Steel Nails
High-strength, low-alloy steels (HSLA) steels were developed to improve the ratio of strength to weight.
Commonly used in automobile bodies and in the transportation industry (the reduced weight makes for better fuel economy ).
Microalloyedsteels Provide superior properties without the use of heat treating. When cooled carefully these steels develop enhanced and consistent strength.Alloy Steels
Rebar corrosion in concrete
M- series steel drill bits coated with titanium
special numbering system
