Abstract: The present invention discloses a system and method for on-line measuring a burden surface in blast furnace to get burden surface information. The system comprises laser emitter(s) disposed above the burden surface and emitting laser beam(s) to continuously scan at least one portion of the burden surface; a video camera configured to shoot burden surface images, each of which comprises a detection point pattern formed by the laser beam incident on the burden surface; an image processing device configured to receive the burden surface images transferred from the video camera and output the burden surface information. As compared with the prior art, the present invention may substantially reduce the cost of the measuring system and obtain burden surface information sufficiently accurate with a large number of actual detection points.

Abstract: The present invention provides a video camera plugged into kiln to monitor and an image processing system using the camera. The video camera is composed of a camera body, a video recorder, a monitor, and a digital thermometer; the image processing system is composed of the camera body mentioned above, a computer and a color monitor. Especially, the present invention is used to monitor material surface during the smelting in a blast furnace; process the image by a computer, describing quantificationally the airflow and temperature distribution of the material surface; monitor the operation state of charging chute or bell, the material stream, and the abnormality in the furnace such as pipeline and material collapse. The advantages of the present invention: Micro camera used to obtain IR image in the furnace, pint-sized, low cost, easy installation, simple maintenance, long service life, and the maintenance performed without stopping production.
