Abstract

In a device for longitudinal field heating of metallic stock, a coil (21) having two coil halves (9, 10) is provided, through which the stock is to be guided. In this case, each coil half (9, 10) includes one or more turn halves (2, 3; 14, 15; 16, 17), which are arranged one behind the other in the transport direction of the stock, and connecting elements (7; 18). Each two turn halves (2, 3; 14, 15; 16, 17) assigned to one another form one complete turn (1), the ends of these turn halves (2, 3; 14, 15; 16, 17) ending at a slight distance to one another and each turn half end being connected in an electrically conductive way to a connecting element (7; 18). The respective connecting elements (7; 18) connected to neighboring ends of two turn halves (2, 3; 14, 15; 16, 17) form a pair insulated in relation to one another by solid insulators. For simple introduction and removal of the stock, the coil halves (9, 10) may be pulled apart transverse to the transport direction to form two introduction passages. The heating appearance of a coil (21) of this type is extensively congruent with the heating of an encompassing longitudinal field coil.
