A Blast Furnace Charge Level Detection Method Combining Distance Measurement and Temperature Measurement

Abstract

The invention provides a distance measuring and temperature measuring combined detection method for blast furnace burden surface and can realize real-time monitoring of a burden surface shape in a production state of a blast furnace. The distance measuring and temperature measuring combined detection method comprises the following steps: different radar nodes are mounted in different positions in one radial direction at the top of the blast furnace, wherein each radar node comprises a radar and a radiometer mounted on an antenna of the radar, and the radar comprises the antenna; the radars and the radiometers are used for performing scanning measurement on the whole stock line in radial directions in the blast furnace, and when each radar acquires stock line distance information in one radial direction in the blast furnace, the radiometer mounted on the antenna of the radar acquires temperature information of the whole stock line in the same radial direction; the acquired stock line distance information and stock line temperature information are processed, and burden surface information matched with internal dimensions of the blast furnace is obtained. The invention relates to the field of radar monitoring of the blast furnace burden surface.

Description

technical field [0001] The invention relates to the field of blast furnace radar material level monitoring, in particular to a blast furnace material level detection method combining distance measurement and temperature measurement. Background technique [0002] In recent years, my country is a big country of iron and steel, and the metallurgical industry is of great significance to the development of the country. Due to the very harsh environmental conditions of the blast furnace: high temperature, high pressure, dust, etc., the internal working mechanism of the blast furnace has not been understood by people. And mastering the distribution of the material surface inside the blast furnace can better control the material distribution to ensure that the materials in the furnace fully react. This is also an important way to increase blast furnace output and reduce fuel ratio, thereby improving the economic benefits of blast furnace production, saving energy and reducing emiss...
