Coils of strip to be annealed are placed in a furnace with their eye vertical and are heated to the annealing temperature by heating elements on the furnace side wall at the same elevation as the coils. An insulation shield is provided between the heating elements and the coil. This may be a cover surrounding the coil in spaced relationship therewith and extending the full height of the coil.
