On-line blast furnace charge level measuring system and method

Abstract

The invention provides an on-line blast furnace charge level measuring system and method. The on-line blast furnace charge level measuring system comprises a first laser scanner and image processing equipment connected with the laser scanner; the first laser scanner is installed at the top of a blast furnace to scan complete charge level information and transmit the charge level information to the image processing equipment, the image processing equipment generates a three-dimensional charge level image of the blast furnace charge level according to the charge level information, and the first laser scanner is a three-dimensional laser scanner. The charge level is comprehensively scanned through the three-dimensional laser scanner installed in the blast furnace and a slide way of a fixing rod, the scanning process is high in automation degree, short in measuring time, high in measuring accuracy, and on-line real-time and complete three-dimensional charge level images can be obtained to obtain charge level information meeting the practicality better then. The requirements for observing the charge level shape more visually and obtaining the chare level information more completely are met truly.

Description

technical field [0001] The invention relates to the field of blast furnace measurement in iron and steel metallurgy, in particular to an online measurement system and method for blast furnace material level. Background technique [0002] With the continuous improvement of blast furnace ironmaking technology and equipment, breakthroughs have been made in blast furnace online monitoring and diagnosis technology. Especially in the online monitoring of the furnace top, from the initial furnace top camera, to infrared imaging, and now to the current laser scanning online measurement of material level technology, the perspective of the top of the blast furnace is becoming clearer and more effective in guiding the operation of the blast furnace. bigger and bigger. In particular, laser on-line measurement of material level technology has made great progress in both software and hardware of the system, and is gradually at the forefront of on-line monitoring and diagnosis of blast fu...
