Question: a long roll of 2rnwide and 05cm thick manganese steel...

Question details

A long roll of 2-rn-wide and 0.5-cm thick Manganese steel plate coming off a furnace at 820°C and entering a 9-rn long oil bath at a steady velocity of 20 mlrnin for quenching process at 45°C. You are required to evaluate the quenching process and the sizing of a cooling equipment for maintaining the oil bath temperature at 45°C if it is assumed that the heat transfer coefficients on both sides of the plate are 860 W/m2K,
