12.5 Iron And Steel Production

12.5 Iron And Steel Production 12.5.1 Process Description1-3 The molten iron and slag are removed, or cast, from the furnace periodically. The casting process begins with drilling a hole, called the taphole, into the clay-filled iron notch at the base of the hearth. During casting, molten iron flows into runners that lead to transport ladles.

The Truth About Cast Iron Pans: 7 Myths That Need To Go

Nov 07, 2014Vintage cast iron tends to have a satiny smooth finish. By the 1950s, as production scaled up and was streamlined, this final polishing step was dropped from the process. The result? Modern cast iron retains that bumpy, pebbly surface. The difference is more minor than you may think.

What is Ductile Iron?

Ductile Iron is a type of cast iron known for its impact and fatigue resistance, elongation, and wear resistance due to the spherical (round) graphite structures in the metal. Ductile Iron is also called ductile cast iron, spheroidal graphite cast iron, or nodular cast iron. Learn more!

Are cast iron pans unsafe?

Cast iron pans can leach a sizeable amount of iron into your food, exceeding dietary intake in some cases. Acidic foods will contribute to much more leaching while an old, heavily-seasoned pan will leach much less iron than a newer one. Some of you may be wondering why cast iron (and carbon steel) are uniquely susceptible to this leaching process.

Cast Iron: Properties, Processing and Applications

Cast iron is an iron alloy containing 2 wt.% – 4 wt.% carbon, 1 wt.% – 3 wt.% silicon and smaller amounts of minor elements [1]. In comparison, steel has a lower carbon content of up to 2 wt.% and a lower silicon content. Cast iron can also be further optimized by alloying with small quantities of manganese, molybdenum, cerium, nickel, copper, vanadium and titanium before being cast.
