Application of Radar High Temperature Level Sensor in Blast Furnace

The level of the blast furnace is a very important measurement data in the steel industry. It plays a very important role in the quality control of steel production, the improvement of production efficiency and the improvement of production safety.

blast furnace

The level measurement points on the blast furnace include the measurement of two kinds of media: the level measurement of the furnace top mineral material and the level measurement of the molten iron of the torpedo tanker.

However, due to these conditions, the process temperature is very high (generally more than 300 ℃). Level measurement on blast furnaces has always been a problem.

For a long time, major steel manufacturers have been committed to finding an economical solution with long service life, reliable performance, low maintenance, and high measurement accuracy.

In the working condition of a blast furnace, there are usually three main measurement requirements for level measurement:
Blast furnace material level measurement;
Level measurement of blast furnace distribution bin;
Torpedo tank hot metal level measurement.

Application of Radar High Temperature Level Sensor in Blast Furnace
  1. Blast furnace material level measurement.
    Need to use the level sensor to measure the mineral material to be added to the blast furnace. The control of the material level needs to ensure that the material level is maintained at a certain height. The height of the blast furnace silo cannot be empty. Otherwise, there is no guarantee that the mineral material of the cloth bin will be supplied in time. Do not make the silo material level too full, resulting in overflow. Generally, the maximum measurement range required for this measurement point is about 5-6 meters.
  2. The main difficulty in measuring the slag level of the blast furnace distribution bin is: the temperature at the top of the bin top is very high, generally exceeding 600°C. The top thickness of the silo roof is relatively large, generally about 1 meter to 1.5 meters.
    The outlet temperature at the installation location of the level gauge generally exceeds 600°C. After repeated research, it is found that the high temperature is mainly caused by the radiant heat of the high temperature medium in the warehouse. Guide wave elbow can be made to avoid the high temperature gas at the outlet of the warehouse roof installation.
    In addition, in order to reduce the influence of conduction heat, the length of the entire waveguide is more than 2 meters. So that the high temperature gas in the tube can get enough cooling pipe section. After installing the guided wave elbow, the temperature of the installation flange is less than 100℃.
  3. Measurement of molten iron in torpedo tanks.
    The temperature of molten iron is as high as 1000℃ or more. But because the measured medium is liquid, the main problem to be solved is how to solve the problem of high temperature.
    At this measurement point, three different methods can be used to solve the high temperature problem.
    • Install compressed air channels on the extended installation standpipe. Inject compressed air to reduce the process temperature of the horn antenna port of the radar level gauge.
    • Design of guided wave elbow. Avoid ultra-high temperatures caused by radiation.
    • Keep a certain distance between the horn antenna of the radar level sensor and the installation port. To reduce the ultra-high temperature in the process.

The application of the radar level sensor on the blast furnace can take full advantage of the characteristics of solid-type radar, and the cost performance is very high. Radar High Temperature Level Sensor provides an ideal solution acceptable to customers for blast furnace level measurement applications.
