Problems solved by technology

Although this interlocking protection method can reduce the temperature, the air permeability of the sintered ore added with water will become poor, which is not conducive to the subsequent blast furnace production
Moreover, once there is a problem in the detection of the above-mentioned material surface temperature detection device, it will also cause safety problems such as burning of the tape machine due to high temperature.

Abstract

The invention discloses a neutral network based temperature control method and system for a ring cooler. The method comprises the following steps of: obtaining a current detection temperature of eachtemperature zone by a temperature detecting device arranged in the temperature zone of the ring cooler; inputting the current detection temperature of each temperature zone into a pre-trained neutralnetwork model to obtain a predicating temperature, namely the temperature, obtained by considering mutual coupling and other interference factors of the temperature in each temperature zone, of the temperature zone; and comparing the predicating temperature of each temperature zone with a temperature threshold value which corresponds to the temperature zone, and regulating air quantity output by an air blower which corresponds to the temperature zone which exceeds the temperature threshold value, thereby realizing regulation on the temperature in each temperature zone. According to the embodiment of the invention, temperatures of various zones in the ring cooler are monitored, and effective decoupling control can be realized through a neural network, so that stable control on the temperature of each temperature zone in the ring cooler is realized.

Description

technical field [0001] The invention relates to the field of iron and steel smelting, in particular to a method and system for controlling the temperature of an annular cooler based on a neural network. Background technique [0002] In iron and steel production, iron-containing raw material ores need to be sintered by a sintering machine before being smelted in a blast furnace. The sintered ore obtained by sintering in the sintering machine is cooled by the ring cooler, and then transported to the sintered ore screening system by the belt conveyor for screening, granulation and other treatments. [0003] figure 1 It is a schematic diagram of the basic structure of a sintering system. With this sintering system, the raw materials stored in the raw material ore bin are fed into the mixer through the batching scale, and the raw materials are added with water through the mixer, mixed, and then enter the mixing tank. The mixed material is evenly arranged on the sintering machi...
