Definitions
- the present invention relates to a method and an apparatus for measuring the remaining amount of refractory material in a molten steel pan, which can easily and accurately measure the remaining amount of refractory material in a molten steel pan used for transporting molten steel in a steelmaking factory.
- a steel pan used to transport molten steel to a continuous casting facility or the like in a steelmaking factory has a structure in which a refractory is lined on the inner surface of a bottomed cylindrical iron shell, and its inner diameter and height are several meters. It is a structure. It is inevitable that the refractory on the inner surface of the pan is gradually worn out by contact with high-temperature molten steel. The refractory in the worn part is repaired by regular repairs.
- the laser rangefinder 2 is installed in the upper outer periphery of the molten steel pan 1, and the distance to the surface of the refractory 3 is measured while scanning in the horizontal direction and the vertical direction, and the remaining amount of the refractory is determined. There are also attempts to find it.
- This method has an advantage that a relatively inexpensive laser distance meter 2 can be used.
- it since it is not easy to accurately set the measurement reference point where the laser distance meter 2 is installed, there is a problem that a measurement error increases. In particular, in order to grasp the transition of the wear state over time, it is desirable to perform measurement with the same measurement reference point at each periodic repair.
- the mark of the measurement reference point attached to the iron skin of the molten steel pan 1 disappears due to damage of the iron skin, adhesion of slag, etc., and it is difficult to repeat measurement with the same measurement reference point. Met.
- Patent Document 2 describes a method of measuring a profile of a refractory on the inner surface of a molten steel pan using a time pulse type light wave distance meter installed on the bottom surface of the molten steel pan.
- the coordinate origin of the light wave distance meter is determined by measuring the distance to a detachable reference position indicator installed on the upper outer periphery of the molten steel pan. According to this method, it is possible to repeat measurement using substantially the same measurement reference point.
- this method has a problem in that it requires a step of attaching at least three sets of reference position indicators and measuring the distances to the respective reference position indicators, which makes measurement work complicated.
