Abstract

The invention relates to the technical field of blast furnace smelting and particularly relates to a method for establishing an operating model of a blast furnace. The method comprises the steps of acquiring original data in the production process of the blast furnace; acquiring a process parameter of the blast furnace on the basis of the original data; acquiring state mode recognition results of the blast furnace in various control links in a cluster analysis way on the basis of the original data and the process parameter; acquiring at least one furnace condition on the basis of the mode recognition results; determining a regulating scheme corresponding to each of the furnace conditions; and establishing the operating model of the blast furnace on the basis of the furnace conditions and the regulating schemes. Due to the establishment of the operating model of the blast furnace, different furnace conditions can be accurately and rapidly handled according to the operating model, it is not needed to judge the furnace conditions by experienced operating personnel on site, and furnace condition abnormality caused by temporal judgment faults of the operating personnel and blast furnace damage caused when effective handling measures are not taken in time are also avoided.

Description

technical field [0001] The invention relates to the technical field of blast furnace smelting, in particular to a method for establishing a blast furnace operation model. Background technique [0002] Blast furnace ironmaking is currently the main way for iron and steel enterprises to produce pig iron. The blast furnace is huge and there are many auxiliary systems. A large blast furnace detects thousands of pieces of data per minute, and the blast furnace production process is a multi-variable and time-varying complex process. In the industrial process, the furnace body is closed, and it is difficult to obtain the physical and chemical changes inside the blast furnace by using conventional detection equipment and detection methods. The operator judges the furnace condition on site and gives the corresponding treatment plan. For large-scale blast furnaces, once the operator makes a wrong judgment, the furnace condition will be abnormal, and if no effective treatment measures...
