Title: Method and apparatus for measuring thickness of slag
Inventor: PARK JUN-HYUNG
IPC: B22D2/00
Filed: 1999-12-24
Abstract: PROBLEM TO BE SOLVED: To eliminate measurement error of the interface between molten steel and slag due to solid phase slag existing on a slag layer by detecting the interface between air and slag and the interface between slag and molten steel from the graph of the moving distance of an immersion rod vs variation of load. SOLUTION: Variation of load value due to the falling distance of an immersion rod is detected and the interface between air and slag is detected. The immersion rod is lowered by 180 mm from the immersion position 262 mm at that time. A decision is then made whether the moving distance of the immersion rod is equal to 442 mm which is the sum of the interface position (262 mm) of slag plus 180 mm or not and the immersion rod is lifted after it is moved further downward by 180 mm. The load value is varied to have a predetermined inclination b. When the immersion rod is lifted up to the interface between slag and molten steel, inclination of load variation decreases on the interface b between slag and molten steel. Subsequently, the immersion rod passes through the interface between molten steel and slag and reaches a slag layer.  When it passes through the interface between slag and air and being reset to the initial position, driving of a motor is stopped.
