Optical measurement of the charge profile of the blast furnace
The slope sensor provides access to angle related data depending on the materials and their loading conditions; this is essential for using estimated load models. This equipment can guide the blast furnace operator and help him to obtain the optimal adjustment of the spread of material and gas inside the furnace. It is particularly effective from the metallurgical point of view when it is backed up with temperature measurements and gas analysis. The purpose of this report is to summarize the various techniques used to obtain this measurement, and to compare them. Optical Measurement: The principle consists of scanning the surface of the blast furnace charge with a laser beam in a known plane which can be selected. The light beam impact is then observed by means of a very sensitive video system situated in a different plane. Other Measurement Techniques: The other measuring systems are: mechanical sensors and sensors using microwaves. The advantage of mechanical sensors is that of being cheaper, but microwave and optical sensors provide access to a larger area of the load. However, they are more expensive.
