In-furnace raw material moisture detection system

Abstract

The invention relates to the technical field of blast furnace smelting, and particularly discloses a furnace raw material moisture detection system. The system comprises a conveying module and a detection module, the conveying module comprises a conveying support and a conveying belt, the conveying belt is installed on the conveying support, and the conveying belt can bear the raw materials entering the furnace and drive the raw materials entering the furnace to move in the material flow direction; the detection module comprises a microwave signal transmitter, a microwave signal receiver and a signal processing assembly, the microwave signal transmitter and the microwave signal receiver directly face each other, one is located above the conveying belt, the other is located below the conveying belt, the microwave signal transmitter is used for transmitting microwave signals, and the signal processing assembly is used for processing the microwave signals; the microwave signal receiver is used for receiving microwave signals of the furnace entering raw materials penetrating through the conveying belt and located on the conveying belt, and the signal processing assembly is used for processing the microwave signals received by the microwave signal receiver. By means of the structural design, accurate weighing of raw materials entering the furnace is achieved, the accuracy of subsequent compensation is guaranteed, and the frequency of fluctuation of the furnace condition of the blast furnace is reduced.

Description

technical field [0001] The invention relates to the technical field of blast furnace smelting, in particular to a moisture detection system for raw materials fed into the furnace. Background technique [0002] The raw materials fed into the blast furnace generally include burnt ore, ball ore, raw ore and coke, etc. The raw ore usually includes many different varieties. Due to the different production and transportation links of various raw materials, the moisture fluctuation of the raw materials is relatively large. Under normal circumstances, the maximum temperature of the sintered ore for direct delivery can reach about 50 °C, but most of them are at room temperature, and most of the temperature of the sintered ore is also at room temperature, and the moisture of the sintered ore pellets is relatively low. Zero (except for being wet by rain during the rainy season). For coke, the commonly used dry quenching moisture is generally within 3%, while the water quenching moistu...
