Abstract
Disclosed is a method and device for determining the loss on ignition of at least part of an iron and steel product during passage through a furnace upstream of a descaler. The device includes electromagnetic sensors, with at least one arranged to scan the product's lower surface near the furnace outlet, the sensor oriented so the scanning plane of the electromagnetic radiation from the sensor is perpendicular to a direction of movement; a set of at least two electromagnetic sensors upstream of the descaler, oriented so their scanning planes are substantially on a single plane perpendicular to the direction of movement of the at least part of the product; and at least two electromagnetic sensors downstream of the descaler, oriented so their scanning planes are substantially on a single plane perpendicular to the product's movement direction. The sensors determine the height of the product upstream and downstream of the descaler.
