The amount of coke required for the production of one ton of hot metal in a blast furnace can vary, but on average, it takes about 800-1000 kilograms of coke per ton of hot metal. Coke is used as a fuel and reducing agent in the blast furnace to help convert iron ore into molten iron.
that would depend on the size of the blast furnace.
Approximately 770 kilograms of coking coal are needed to produce one ton of steel through the traditional blast furnace method. The coking coal is used as a fuel and as a reducing agent in the steelmaking process, where it helps convert iron ore into molten iron in the blast furnace.
Even though the ores of both the metals is quite cheap, Sodium has to be extracted through electrolysis which is quite an expensive process where as Iron is extracted from Blast furnace which is comparatively cheaper to run.
Iron can rust. Actually it is because the iron is not strong enough to be able to handle the pressures that steel can. Pure iron is to soft and weak to be of any use and the iron from the blast furnace has too much carbon in it to be useful. That is the real reason
Steel is actually iron that was smelted at much higher temperatures than normally (usually with a blast furnace). This extreme heat that is added removes many more impurities, actually making it denser and harder than usual iron.

You have to mine iron ore and coal make a furnace and melt the iron ore to make iron ingot. Update: THANK YOU SOOO MUCH!!!!!!
Steel is iron alloyed with carbon, usually less than 1% and then run through a blast furnace to remove as much of the impurities that case weakening
The basic concept of a blast furnace hasn't changed in more than 100 yrs. Modern furnaces are of course more complex due to newer technologies. First of all the furnace is basically a steel tank, inside it is lined with brick or gunite. The outside shell is protected from the heat by hundreds of "coolers" which are located around the entire furnace. Coolers are usually made from copper and have water inlets and outlets; water does not enter the inside of the furnace but is circulated in a closed loop system through a network of piping. At the bottom of the furnace are openings called tuyeres (ta-weers) through which hot air is blown into the furnace. The tuyeres are connected to a large brick-lined pipe called a bustle pipe. The bustle pipe is connected to a series of very large stoves. Outside air is fed into the stoves where it is heated. The heated air is then blown into the bustle pipe, through the tuyeres and into the furnace. The tuyeres can also be piped to allow the use of oxygen, pulverized coal, and natural gas to enhance the heat. Raw material is loaded into the top of the furnace by conveyor or a skip car which runs on a track pulled by cables. The raw materials are iron ore, limestone, coke and alloys chosen by the steelmaker. At the bottom of the furnace is an opening called the tap hole. The tap hole is plugged by a machine called a mud gun, the mud gun is loaded by hand with "mud" which is a high grade refractory that does not melt under the intense heat. After the materials reach the desired temp (usually about 3500 deg F) another machine called a tap drill drills out the mud to let the molten metal out of the furnace; this is known as "casting". Molten metal and slag are separated by a series of channels, slag (girl) will flow to a pit or slag car to be carried away. The slag is cooled to be used in a variety products such as an additive in concrete. The metal is channeled to bottle cars to be transported to different areas of the mill for processing. This is a very basic overview of a blast furnace, they are highly complex and very dangerous!
Impure iron has higher carbon content, making it more brittle and prone to cracking. When the iron is bent, it redistributes the stresses and strains within the material, making it less likely to break. Therefore, impure iron straight from the blast may be more susceptible to failure compared to bendy iron.
electrolysis requires a lot of electrical energy, however this is not the same with reduction with carbon (blast furnace), which is a lot cheaper than electrolysis, but not always the most practical. :)
