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.

The present invention relates to an RFID tag holder, which comprises an RFID tag carrier used to carry an RFID tag, and a base having a circular surface, a holding portion and at least one magnetic component disposed therein. The shape of the circular surface matches that of the disposing hole, the magnetic component is used to make the disposing hole magnetically attachable to combine the base with the disposing hole, and two clip arms of a holding unit grip the holding portion and hold the RFID tag carrier after passing through two through holes of a metal substrate. The RFID tag holder has the following advantages: fast installation, low cost and reusability; is suitable for disposing holes with any depth and size; reduced interference and improved reading effect; no extra processing cost; dust-proof, water-proof and oil-resistant; and better composability, extensibility and flexibility.
