**Luke N Aiden N Nath N Spence!!** **__Chapter one - Iron and Steel making__**

 **Much is said nowadays about the consequences of human activity for the environment.**
 * **__What are the main three raw materials used to make iron?__ **
 * **The three raw materials to make iron are Limestone, coke and carbon. **
 * **__Where do the raw materials come from and how are they transported to the plant?__**
 * **They are all extracted from the ground and they are normally transported by boator train.**
 *  **__How and why are the raw materials processed before they are used in the blast furnace?__**
 * **To extract coke. **
 * **__What role does each of these three raw materials play in the iron-making process?__**
 * **Coke reacts with iron ore to get the oxygen. The limestone reacts with impurities.**

2000m3 * 32 Mg = 64 000 mega jules
 * The amount of energy used in natural gas a year per household is:

The final temperature is: 2083.5 degrees Celsius.** **Mass of each KG element. In 100kg. 94.9% Fe is iron. The amount of energy used per year is 64,000MJ.**

**The amount of steel produce from this reaction is 113.1kg** ** 1395.7kj of energy is needed to melt 1kg of scrap. ** ** How many kg of scrap can be melted with 100kg of hot metal if we need the temperature to be 1650 degrees? ** ** 19.9kg of scrap can be added and melted in the reaction. ** **45.7m cubed.** The height for the ladle must be 3.69m + 0.5m for spillage = 4.14m. ** It takes 60 seconds. What is minimum rising velocity to get out in 60 seconds? 1.3cm/s. __Aiden and Nath And Sam do sum work!!!!!!!!!!!!!!!__ **
 * How Much energy is needed to melt 1kg of scrap? **
 * How many cubic metres will 320 tonnes take up? **
 * What must we make the height of the ladle if we want the surface of the steel mixture to be 50cm below the height of it?
 * How long does it take to flow along it?
