Abstract
PURPOSE: To make it possible to measure definitely a slag flow rate by providing a head sufficient to make slag flow section circle at the halfway point of a slag flow passage and then by measuring the diameter of the circle slag flow section.
CONSTITUTION: At the halfway point of shaft furnace duct 2 carrying shaft furnace slag 1 to water crash facility, discontinous level-difference part 3 is provided and around it, image sensor 4, thermometer 5, index-object lancher 6, and detectors 7 and 8 are provided. The above-mentioned level-difference part 3 has head H0 sufficient to make the section of a shaft furnace slag flow circle when shaft furnace slag 1 falls, and sensor 4 measures sectional diameter D of the shaft furnace slag flow of circle section at a sufficient low part. Thermometer 5 detects the temperature of the shaft furnace slag flow surface and operator 10 calculates the specific gravity of it from the measured value. Measured sectional diameter D of the shaft furnace slag flow is multiplied by cross section A and adropping speed, i.e. flow velocity V, measured by detectors 7 and 8 to obtain volume flow Qv. Then, weight flow Qw can also be obtained from the volume flow Qv and the specific gravity.
