2021/06/11 category：Furnace Metallurgy 资讯中心 2533

The blast furnace top imaging system is the main equipment to monitor and detect the material surface environment on the upper part of the blast furnace. The monitoring range includes the shape of the material surface inside the blast furnace, the air flow, the chute, the chute distribution, the real-time working condition of the equipment in the furnace such as the probe, nozzle, water spray, cooling stave, etc.

Through timely understanding and mastering the charge level of the blast furnace throat and the distribution of gas flow, adjusting the blast furnace operation, maintaining the smooth and stable furnace condition, and improving various technical indicators, it plays an important role.

Technical introduction

The system is mainly composed of infrared thermal imager of blast furnace charge surface and protection and image processing device. The hardware structure diagram of the system is as follows:

System function

1. Real time monitoring the temperature distribution of the charge surface in the furnace before and after the distribution, as well as the distribution of materials;

2. Real time monitoring of the material level in the furnace before and after the distribution and the operation of the equipment in the furnace (such as distribution chute and feeler);

3. Multi point fixed-point temperature measurement and real-time temperature curve display;

4. It can directly measure the temperature of any point in the temperature image;

5. The temperature image at any time is stored in the way of hard disk storage, so as to query the historical data.
