Abstract
PURPOSE: To permit the slag flow rate to be continuously measured with the measuring error decreased by obtaining the solidified layer thickness from the measured values of the quantity of the heat penetrating through the wall of a metallic tub having a given width through which slag is flowing, and computing the slag flow rate from the solidified layer thickness.
CONSTITUTION: The slag flowing through a tube 1 is cooled by a cooling solvent (c) flowing through a hollow part 1a to form a solidified layer (s) on a tub surface 1b, resulting in the variation of the effective sectional area of the tub 1. The thickness of the solidified layer (s) is computed from the heat flow values on a heat flow meter 3 provided on the inner surface 1c1 of a tub wall 1c. To an arithmetic means 4, the constant value at each temperature within the working limits has been inputted from an input key 5. The solidified layer thickness is computed from the heat flow values from the heat flow meters 3, the slag temperatures from slag thermometers 2, the temperatures of the tub surface 1b from embedded thermometers 10, and the constant values. Moreover, the slag level height from an ultrasonic wave receiver 6 and the flow velocity data from flow velocity measuring means (floating monitors 9a and 9b) are inputted to the arithmetic means 4 to compute the flow rate of the slag. These data are outputted to lines 4aW4d. Thus, the flow rate can be measured continuously with the measuring error decreased.
