Embodiment Construction
[0020] In the traditional method of controlling the material surface shape of the blast furnace material distribution, the mechanical probe material distribution control is mainly used: mainly based on a mechanical probe, the mechanical probe follows the material surface in a contact manner. As the smelting progresses, the material surface After the material level drops to a set height, the mechanical probe is raised to start feeding. After adding the batch of furnace materials that have been manually set in advance, the mechanical probe is continued to be lowered to start a new round of feeding process. The traditional method is to select the detection point data of the mechanical probe on the material surface as the basis when the charge level of the blast furnace changes, and take corresponding control operations according to the data of the mechanical probe. This method takes a point value as the controlled object, and the method of controlling the material surface is very ...
