Heat number. An example of a heat number on a plate. A heat number is an identification coupon number that is stamped on a material plate after it is removed from the ladle and rolled at a steel mill. Industry quality standards require materials to be tested at the manufacturer and the results of these tests be submitted through a report, also called a Mill Sheet, Mill Certificate or Mill Test Certificate (MTC).
Electrical energy = Volts x Amps x time = Electrical Power x time. Therefore: Heat energy = mass x specific heat capacity x temperature rise = VIt = Power x time. Example problem A 50 W heater is used to heat a 2 kg block of aluminium.eat energy input = 50x10x60 = 30 000J Heat energy gained by aluminium = 2 x specific heat capacity x 15 = 30 000J Specific heat capacity of aluminium = 30 000/30 =1000J/(kgoC) Notice that the time (10 minutes) has been converted into seconds.
