The Modern Steel Manufacturing Process ThoughtCo

Aug 21, 2020 The BOS method adds recycled scrap steel to the molten iron in a converter. At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 0-1.5%. The EAF method, however, feeds recycled steel scrap through high-power electric arcs (with temperatures of up to 1,650 degrees Celsius) to melt the metal and

Architecture Iron and steel Britannica

Architecture Architecture Iron and steel: The development of construction methods in iron and steel was the most important innovation in architecture since ancient times. These methods provide far stronger and taller structures with less expenditure of material than stone, brick, or wood and can produce greater unsupported spans over openings and interior or exterior spaces.

Refining (metallurgy) Wikipedia

The product of the blast furnace is pig iron, which contains 4–5% carbon and usually some silicon.To produce a forgeable product a further process was needed, usually described as fining, rather than refining.From the 16th century, this was undertaken in a finery forge.At the end of the 18th century, this began to be replaced by puddling (in a puddling furnace), which was in turn gradually

Roman metallurgy Wikipedia

Types of metal used. Many of the first metal artifacts that archaeologists have identified have been tools or weapons, as well as objects used as ornaments such as jewellery.These early metal objects were made of the softer metals; copper, gold, and lead in particular, as the metals either as native metal or by thermal extraction from minerals, and softened by minimal heat (Craddock, 1995).

Damascus Steel: Ancient Sword Making Techniques

Jul 03, 2019 Damascus steel was made from a raw material called wootz steel. Wootz was an exceptional grade of iron ore steel first made in southern and south-central India and Sri Lanka perhaps as early as 300 BCE. Wootz was extracted from raw iron ore and formed using the crucible method to melt, burn away impurities and add important ingredients

ORB: Iron and Steel Production in the Middle Ages

8 Cast Iron Tips from a Cook Who Uses the Stuff Every Day

Aug 24, 2020 There is misconception that cast iron is great at conducting heat. It’s true that cast iron is great at retaining heat once it gets hot, but iron is actually a poor heat conductor. This is why, when you first put a skillet on the stove, it will heat very unevenly.

Welding Cast Iron can make a preacher cuss.

Mild steel has less than 0.2 percent carbon. That’s 0.2% or 2 tenths of 1 percent. That’s not much. Medium carbon steel has more than 0.2% and will harden a little if heated red hot and quenched. Cast iron has anywhere from 3 to 8 full percent of carbon. That’s way more than 10 times what tool steel has.
