Yes,You can heat the cast consists of >2% of carbon by weight % till liquefaction temperature around 1147°C and later by adding CO which reduces the C present in it, and you can get the desired steel by maintaining required amount of C 0.2–0.7% of C - Hypo eutectoid steel 0.8% of C - …read more
Steel. Most of the molten iron from a Blast Furnace is used to make one of a number of types of steel. There isnt just one substance called steel - they are a family of alloys of iron with carbon or various metals. More about this later . . . Steel-making: the basic oxygen processread more
Basic oxygen steelmaking BOS, BOP, BOF, or OSM, also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel.read more

Iron ore is used to make iron and steel eg haematite and magnetite. Iron is produced extracted in a blast furnace by iron oxides with carbon and it is the carbon that removes the oxygen from the iron oxides – the carbon is known as the agent. Coke is a cheap and readily made agent.read more
Ingested is mainly absorbed in the form of Fe 2+ in the duodenum and upper jejunum. The trivalent form and the heme‑bound Fe 3+ component in food has to be reduced by vitamin C. About 1 mg is assimilated daily. Upon reaching the mucosal cells, Fe 2+ ions become bound to transport substances. Before passing the plasma, these are oxidized by ceruloplasmin to Fe 3+ and ...read more
