'' PROCESS OF HEATING A METALLIC WITHIN A PREDETERMINATED TEMPERATURE TOLERANCE BAND AND HEATING SYSTEM TO HEAT A FIRST AND SECOND METAL STRIPS WITHIN A FIRST AND SECOND TEMPERATURE TEMPERATURE BAND. A heating system (50) and a process for heating a metal strip (40) within a predetermined temperature tolerance range while the metal strip (40) consecutively propagates through the heating system (50). The heating system (50) has at least one preceding heating section (52), at least one induction heating section (54), and at least one subsequent heating section (56), with heating sections (52 , 54, 56) being consecutively arranged. The metal strip (40) is heated to a level below the Curie point of the metal strip (40) in the preceding heating section (52). Then, the metal strip (40) is heated to a maximum, approximately the Curie point in the induction heating section (54). Then, the metal strip (40) is heated to a level above the Curie point and within the predetermined temperature tolerance range in the subsequent heating section (56).
