=Questions chapter four:=

**//How many coils of 10 tons can the plant process in a year?//** 100000×25÷1000÷0.75=3333.333333333 kg 3333.333333333×1000×24×365×0.9=26280 coils **//How many cans are produced per year?//** 100000×24×365×0.9= 788400000 cans __ **//How many rejected cans per slab and per year are allowed?//** 2×786.24=1572.48 per slab 1572.48÷2620.8=0.6 per year **//How many square meters storage are required to store a week production?//** 788400000÷52=15120000 400÷12.5=32  100÷7.5=13.33333  13.33333×13.33333×32=5688.9  15120000÷5688.9=2657.8  __ **//Describe the process steps in the making of a beverage can//** First, the raw materials are charged into the blast furnace, and given the required properties. Liquid iron is formed and tapped into large containers, which are than transported. In the steel plant the hot metal is tapped into a hot metal ladle. The hot metal is after that charged with scrap into a converter, in which pure oxygen is blown through a cooled lance. Oxides are created and form a layer of slag on the steel or leave the melt as a gas. After this process the steel is tapped into a steel ladle. The created free oxygen has to be removed before the steel can be cast, by adding aluminium. Aluminium oxide is formed as small particles in the steel. The amount of these particles must be minimised above a critical size to make steel. The steel is poured into a tundish than, which divides the steel over two moulds. After that, the steel must be solidified. The steel slabs are flattened till they’re about 2.5 mm thick. Next, the steel slabs are brought to America and Europe, where further adjustments are added. The plates are formed to a cup, which are than pushed through a ring, because than the cup is smaller at the top and the lower parts. When the sides are thin and high enough, there will be made a bottom in the can. At last, the can is given a coating at the inner and outer parts. If you throw a can away, there is a change it comes back at Corus and will be used for can making again.

When you`re done drinking your beverage you usually throw it away.
 * //Where and how are cans recycled?//**

**//But do you know where it goes to?//** When your trash is picked up by the Garbage car it is transport to: either the local recycling centre or the community drop off sites, or just the junkyard

**//The recycling process begins//** At first the cans are collected in huge amount by recycling companies. Than they get heated to a certain degree and the skin melts off. After that the cans get shredded and crushed into small chip-like pieces. The pieces are put into the furnace and new pieces of iron are added to make a new slab of steel. //**Where and how are cans recycled?**// When you`re done drinking your beverage you usually throw it away.
