Coiling temperature

WebThe sensible heat in a heating or cooling process of air (heating or cooling capacity) can be calculated in SI-units as hs = cp ρ q dt (1) where hs = sensible heat (kW) cp = specific heat of air (1.006 kJ/kg oC) ρ = density … WebJul 18, 2013 · In conventional batch annealed Al-killed steels, cold reductions of around 70%, low coiling temperatures and slow heating rates induce the development of the most desired annealing textures and correspondingly the highest r m values. The optimum cold reduction increases to about 90% in Nb or Ti stabilised interstitial free (IF) steels.
