To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added. In fact, a very simple definition of steel is "iron alloyed with carbon, usually less than 1%." The following text is taken from the Structural Manual For Ironworkers Manual V-Volume I.

Instead, the iron heats up into a spongy mass containing iron and silicates from the ore. Heating and hammering this mass (called the bloom) forces impurities out and mixes the glassy silicates into the iron metal to create wrought iron. Wrought iron is hardy and easy to work, making it perfect for creating tools.

Pig iron has only uses, and most of this iron goes on to a steel mill where it is converted into various steel alloys by further reducing the carbon content and adding other elements such as manganese and nickel to give the steel specific properties.

There are several processes which can be used to turn iron into steel, but the two most common methods are by using electric arc furnaces and oxygen furnaces. Ingredients used in steel production Depending on the method used, different ingredients are needed, although that said, there are 4 ingredients which are widely used in steel production:

The plant uses a direct reduction process to make iron from the ironsand before this is turned into steel. No other operation in the world makes steel in the same way. Major improvements have been made in energy efficiency through co-generation (using waste heat) where New Zealand Steel produces up to 70% of its own electricity requirements.

Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880s, steel was produced using charcoal.

The open-hearth furnace is one way to create steel from pig iron. The pig iron, limestone and iron ore go into an open-hearth furnace. It is heated to about 1,600 degrees F (871 degrees C). The limestone and ore form a slag that floats on the surface. Impurities, including carbon, are oxidized and float out of the iron into the slag.

The combustion of iron ore with other materials in the blast furnace produces molten pig iron, which is then converted to steel.

The iron content, magnetite, is only 20- 30% compared to 50 60 % iron content in red ore. Red ore is also referred to as direct shipped ore because it can be shipped without processing. Taconite needs to be crushed and processed into pellets before it can be shipped to steel mills.

The "o" method was to take small bits of wrought iron (rivets, nails---small cross section stuff) and put them in the charcoal forge and heat them for an hour or more to soak in carbon. You then weld up the scraps into a solid piece of steel. How an old times smith would do a buggy axle?

Whatever your choice of iron (II) salt, you will need to dissolve it in water. Do this as a separate beaker (or other container) from the iron (III) solution to ensure that the iron (III) has not saturated the water. This will allow the most iron (II) to dissolve into the water. Again, a lid will help keep out contaminants, but is not necessary.

Many things throughout your home are likely made of steel. However, not all of them need to be overly strong. When steel is being used to support a structure or other heavy object, the stronger it is, the more you will be able to trust it. To strengthen steel, you need to use a specific type of heating process known as hardening and tampering.

Metal is a great material to work with. It's rigid, tough, malleable and conductive, but sometimes the part we need doesn't exist in any store. In order to create custom pieces, you need to either melt the metal and cast it in a mold, or heat it until it's soft enough to shape with your hammer. Properly melting metals can be a bit dangerous in our home shop, but we can make a coffee can forge ...

Carbon and carbon monoxide combine with the oxygen in the iron ore and carry it away, leaving iron metal. In a bloomery, the fire doesn't get hot enough to melt the iron completely. Instead, the iron heats up into a spongy mass containing iron and silicates from the ore.

Iron was produced by direct reduction of the iron oxide into iron metal. Despite the fact that iron has a melting point of 1540 degrees C, iron oxide can be reduced to metal at 800 degrees C. At a temperature of 1100-1500 degrees C, the reduced iron flows together forming a semi-fused porous mass called a bloom.
