Question 1 A specialty steel producer is setting up its melting furnace to make a 1000kg heat of stainless steel with a specified composition of Fe,Ni,Cr, Mo, and W. You are to melt together appropriate amounts of ferro-moly, ferro-nickel, and three different scrap alloys to achieve the specification. A summary of the charge streams and product is provided in the attached figure. a) Using a basis of 1000kg of product, calculate the weights of the input streams. Note that Mo can be used as a tie component if you choose. b) At the last minute a customer changes the Mo specification to 4.5%. Can this be accommodated using the given charge compositions
