Burnt Wood to cook and heat their houses.
Wood
During the process of steel production the flaws in the steel casting are detected by ultrasonic vibrations.
Fossil fuels are used in thermal power stations for production of electricity. They are used as automobile fuels i.e petroleum. They are used in factories and industries as power source like in Iron or Steel industries.
Argon is used to avoid oxydation of titanium.
Iron XD
It is not known when it was created, but it was first invented in the 13th century CE when Iron and charcoal were combined correctly. "The earliest known production of steel is a piece of ironware excavated from an archaeological site in Anatolia (Kaman-Kalehoyuk) and is about 4,000 years old" "Other ancient steel comes from East Africa, dating back to 1400 BC."

19 Th Century, Bessemer and Carnegie mass production process of steel in furnaces
ore and coke
Nucor Steel Tuscaloosa
The plans drastically reduced the production of steel.
Mendelevium 101 LOL
False
Textiles NOT STEEL
Russian Designed, Twin Hearth Furnaces are the modernized version of the Older Open Hearth Furnaces which now comprise two adjoining furnaces side by side to alternately use up the sensible heat of the gases generated due to the steel making process being carried out in one furnace to heat up the scrap and other materials in the other furnace till the first one is tapped and then the entire process is repeated for the next heat that is to be carried out in the first furnace utilizing the sensible heat of the second furnace. This cycle is alternated and the result is to cut on time of production and minimizing heating up costs. In India these types of furnaces are still being used at State Owned Steel Authority Of India Limited's Bhilai Steel Plant and IISCO Steel Plant. They are followed by Ingot casting route and the Blooming and Billet milling plant.
The Production Budget for Steel was $16,000,000.
Steel makers typically use coke, a type of solid fuel derived from coal, in the steelmaking process. Coke is used in blast furnaces to provide the necessary heat and carbon for the reduction of iron ore into molten iron, which is then used to make steel. Additionally, natural gas and electricity are also used as alternative fuels in some steel production processes.
The Production Budget for Man of Steel was $225,000,000.
The Production Budget for Real Steel was $110,000,000.
