Embodiment 1
[0023] Example 1: see figure 1 , a method for controlling the furnace top temperature by adjusting the upper and lower parts of a blast furnace under oxygen-enriched conditions, the method comprising the following steps:
[0024] Step 1. Real-time detection of furnace top temperature;
[0025] Divide the top of the blast furnace into several equidistant areas in the radial direction, and obtain the real-time data of the top temperature of each area through the temperature detection device installed in each area;
[0026] Step 2. Judgment and analysis of furnace condition;
[0027] Step 3, the upper and lower parts of the blast furnace are adjusted;
[0028] According to the judgment and analysis of the real-time furnace condition, when the furnace temperature is abnormal, start the adjustment;
[0029] Step 4. Real-time information feedback;
[0030] The change of the furnace top temperature in the above-mentioned area is judged in real time, and the second step is entered...
