The invention discloses a moisture content measuring device, which is used for measuring the moisture of sintered ore in the sintering process, including a material acquisition system, a pressure system, a material receiving plate, an image detection system, a model training system and a control system; the material acquisition system is set At the feed port of the pressure system, it is used to collect materials as samples; the pressure system squeezes the samples; the material receiving plate is set under the discharge port of the pressure system to receive samples; the image detection system is set at the receiving port At the material plate, the image of the sample is obtained and the image characteristics are analyzed; the model training system receives the data from the image detection system, trains the convolutional neural network model, and outputs the moisture content of the sample through the trained convolutional neural network model; the control The system is used to control the operation of the material collection system and the pressure system. The invention also provides a water content detection method. The invention can quickly detect the moisture content of the sintered ore, and has simple structure and high precision.
Description
technical field [0001] The invention relates to the field of iron and steel production, in particular to a moisture content measuring device and a detection method. Background technique [0002] In the iron and steel industry, the moisture content of sinter has an important impact on the final product quality and economic benefits of sinter. The level of moisture content will not only affect the air permeability of sinter, but also directly affect the sintering process, such as the influence on the over-burning and under-burning state of sinter, in addition, it will also affect the final sinter Quality affects, such as drum strength, FeO content, etc. [0003] At present, the commonly used methods for determining the moisture content of sinter are drying and weighing detection method, infrared moisture analyzer detection method and neutron determination method. Drying and weighing detection method is a general method for moisture measurement of powdery materials. Its princ...
