Abstract
A method for continuously measuring slag foaming within a converter during blowing and an apparatus for practising the method are disclosed. In this method, the foaming slag level is determined by detecting and processing a beat signal developed between the frequency-modulated transmitted wave and the reflected wave of a microwave radar. The apparatus for practising this method comprises a microwave generator, an antenna and a waveguide, and signal processing circuitry. The microwave generator generates frequency-modulated microwaves and supplies them to the antenna which is provided with a waveguide for directing these microwaves into the converter. The antenna with the waveguide are provided with water-cooling means and air purge means to overcome the heat, dust and splash from the converter. The signal processor determines the foaming slag level by detecting and processing the beat signal between the microwaves reflected from the slag within the converter and the reflected waves from a reference reflector added to the antenna.
