Abstract
A resident measurement system for a charge level of a blast furnace includes a chamber, a servo system, a distance measurement unit, and a cooling-cleaning unit. The chamber is combined with a lateral furnace wall of the blast-furnace, covers an opening of the furnace wall, and has a pivoting hole. A pivot of the distance measurement unit is pivotally disposed at the pivoting hole, and the distance measurement unit is driven by the servo system to perform a motion with the pivot as a movement center, so as to measure the charge level. The cooling-cleaning unit is used to supply a high-pressure gas, which flows through the distance measurement unit to perform cooling and cleansing operations. The measurement system is small in dimension, and capable of scanning the charge level in an environment with high temperature, high concentration of dust, and high corrosion in the blast furnace, establishing charge level information into a two-dimensional charge level mode, and obtaining a charge level profile distribution situation in real time, thereby promptly modifying a burden distribution mode.
