Closed-loop control method for temperature of top gear box of blast furnace based on IOT (Internet of Things)

Abstract

The invention belongs to the technical field of blast furnace, and discloses a closed-loop control method for the temperature of a top gear box of a blast furnace based on the IOT (Internet of Things). The method employs a solar power supply module, a blast furnace parameter configuration module, a main control module, a feeding module, a ventilation module, a heating module, a cast iron module, aresidue processing module, a display module, an external power supply module, and a sensor module. The external power supply module can be used for continuing the operation when the light is not sufficient, and the sensor module and the main control module can achieve the intelligent control of the temperature. Meanwhile, the residue processing module is used for the thermal insulation processingof the molten blast furnace residues, and enables the metal iron in the blast furnace residues to be fully deposited, and enables the metal iron to be gathered at the bottom of a slag car in advance,thereby reducing the content of metal iron in the blast furnace residues, simplifying the production procedure, and reducing the energy consumption of production. Moreover, the content of the metal iron in the blast furnace residues of a second slag pit is higher, thereby facilitating the preparation of slag iron at a higher level.

Description

technical field [0001] The invention belongs to the technical field of blast furnaces, and in particular relates to a method for closed-loop temperature control of a top gear box of a blast furnace based on the Internet of Things. Background technique [0002] The blast furnace is made of steel plate as the furnace shell, and the shell is lined with refractory bricks. From top to bottom, the blast furnace body is divided into five parts: the furnace throat, the furnace body, the furnace waist, the furnace bosh, and the hearth. Due to the good technical and economic indicators of blast furnace ironmaking, simple process, large production volume, high labor production efficiency, and low energy consumption, the iron produced by this method accounts for the vast majority of the world's total iron production. During blast furnace production, iron ore, coke, and flux (limestone) for slagging are loaded from the top of the furnace, and preheated air is blown in from the tuyeres l...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the existing blast furnaces are powered by the traditional method, which consumes electric energy; at the same time, the quality of the blast furnace slag obtained from the treatment of the tailings after ironmaking is low, and automatic control cannot be realized
