    (ii) Name the material produced in this furnace-Pig iron
    (iii)Name part A and describe how the charge is melted-the furnace charge melts an electric passes between the electrodes and the scrap metal the temperature around the ark rises to 1200C  blowing with oxygen to oxidise elements such as carbon, silicon and maganese
    (iv)?
    (b) (i) Titanium
    (ii) the benifets of titanium are its corrosion resistant and its strength to weight ratio.
    (c) (i)Hardening, case hardening and annealing
    (ii) annealing is carried out by heating to predetermined temperature holding for a certain time and then cooling to room tempreture]]>     2020-03-24 19:05:28 UTC https://padlet.com/mo2018_27968/jemvapfnvzfx/wish/473407391
