Abstract

The invention relates to a composite control device of an ignition furnace of a sintering machine, comprising a detection instrument, a control device consisting of an industrial computer, a programmable logic controller (PLC), an instrumentation cabinet and an actuator of a regulating valve, wherein the programmable logic controller (PLC) is provided with a Fuzzy-PID composite control program, a CPU, a digit input template, a digit output template, an analog input template and an analog output template; the detection instrument is composed of an ignition furnace temperature sensor, a pressure sensor, a flow sensor and a flow regulating valve. The invention has the advantages of improving air permeability of the ignition furnace of the sintering machine, enhancing the thickness of a sintering layer, increasing the speed of the sintering machine, and lowering the negative pressure of the sintering machine, thus realizing low-temperature thick-material layer sintering technology, reducing fuel consumption for sinters per ton, improving utilization factor of the sintering machine greatly, bettering the quality of sinters and having enormous economic benefit.

Description

technical field [0001] The invention relates to a detection and control device for an ignition furnace of a sintering machine, in particular to a composite control device for an ignition furnace of a sintering machine. Background technique [0002] As we all know, the ignition furnace of sintering machine can determine the quality, physical properties and chemical composition of sintering, and has a profound impact on the quality of blast furnace molten iron and ironmaking efficiency. The ignition furnace control is an important link in the sintering production control. The temperature of the ignition furnace and the opening of the valve not only affect the vertical sintering degree of the sintering process, but also affect the yield and productivity of sintering ore. The temperature of the ignition furnace and the opening of the valve are large, although the sintering speed is fast, the yield is low and the amount of ore returned is large; the temperature of the ignition fu...
