PROBLEM TO BE SOLVED: To provide a hot rolling equipment line advantageously suitable for the manufacturing of a product, particularly, a grain oriented electrical steel sheet for which high temperature heating of a slab is essential, by realizing an equipment structure capable of heating the slab uniformly in the width direction of the slab, in a hot rolling equipment line incorporated with a vertical type electric heating furnace. SOLUTION: In the hot rolling equipment line in which a gas heating furnace 1, roughing-down mills 2-4, and a continuous finishing mill 5 are successively connected through a roller table 6, at least one vertical type electric heating furnace 9 is arranged on one side of the roller table, while a slab turning device is installed near the roller table.
