In traditional technology, mechanical probes are generally used to collect data on the blast furnace charge level, but the measurement range is small and the data error is large, making it difficult to analyze the distribution of the charge level in the furnace. Later researches and developments have been made to monitor the blast furnace charge level by means of infrared imaging or other imaging methods. However, due to large temperature changes and a lot of dust on the top of the charge surface, this method has caused great interference, and it is difficult to accurately obtain the shape of the charge surface. Another part of the measurement method is to install a certain number of ranging radars in multiple positions on the furnace roof to obtain the approximate shape of the material surface. However, due to the large number of sensors and the complexity of the sensing system in this method, the installation and maintenance of multiple equipment Both bring difficulties to on-site operators, and it is difficult to guarantee the real-time performance of the system operation, or the number of sensors is too small to reflect the shape information of the material surface.

本发明实施例提供了一种高炉料面形状测量方法,如图1所示,所述方法包括以下步骤:The embodiment of the present invention provides a method for measuring the shape of a charge surface of a blast furnace, as shown in Figure 1, the method includes the following steps:
S1:通过安装于高炉炉顶的测距雷达对高炉内料面的位置进行测量。S1: The position of the blast furnace inner material level is measured by the ranging radar installed on the top of the blast furnace.
