PURPOSE: A device and a method for measuring the temperature of a casting slab are provided to minimize interference in cooling water and residual water with respect to a pyrometer unit, thereby accurately measuring temperature in a traversal direction of a casting slab. CONSTITUTION: A device for measuring the temperature of a casting slab comprises a pyrometer unit, an opening/closing valve(205), and a controller(206). The pyrometer unit measures the temperature of a casting slab while being transferred on a frame. The opening/closing valve is mounted to a spray nozzle spraying cooling water to the casting slab. The controller transfers he pyrometer during a time period in which a cooling water discharge through the spray nozzle is prevented by applying off-signals to the opening/closing valve, thereby controlling to measure the temperature of the casting slab. |
