Question 1 [29] 1. How has the by-passing of the blast furnace process changed the production of iron and steel? (3) 2. Do you think it is important for physical metallurgist to be involved in the steel convertor stage? (3) 3. What is the difference between batch and continuous casting? (6) 4. Discus atleast three ladles found in the secondary steel making plant. (9) 5. A spectrometer is used to measure percentage composition of metals. If ingot cast steel parts are measured; what could be the detrimental element found from these set of parts? Also, what is expected from these range of metals? (8) Question 2 [32] 1. Low carbon steels are the main contributor to the flat-rolled produces. Discus what it means to a metallurgist when the term "low carbon steel" is mentioned. (5) 2. Flat-rolled products are a feed to the plastic manufacturing products. How does anisotropy impact on this process of manufacturing? (3) 3. Differentiate the impact of drawability and stretchability to strip steels. (4) 4. IF and AIK are favourable range of strip products. Using the strachability and drawability effect, how does these two grades differ. (8) 5. Compare the properties of IFHS and bake hardenable steels. (6) 6. Why would it be possible for strip/sheet steels to show difference in properties after annealing by batch or continuous? (6) Question 1 [29] 1.
