Thickness control method and control system of mixed material layer

Abstract

The invention relates to a thickness control method of a mixed material layer, comprising the following steps of: acquiring round roller speed, round roller output coefficient, speed of mixed material sintering, width of a sintering pallet and density of the mixed material; multiplying the round roller speed with the round roller output coefficient to obtain a product which is then divided by the product of the speed of the mixed material sintering, the width of the sintering pallet and the density of the mixed material to obtain a quotient which is taken as the current thickness of the mixed material layer; and regulating the ratio between the round roller speed and the speed of the mixed material sintering to cause the current thickness of the mixed material layer to be close to the set layer thickness. The invention also discloses a thickness control system of the mixed material layer. The method realizes control to the thickness of the mixed material layer by a soft-sensing mode, thus not only saving the production and maintenance cost of a manufacturer, but also having the advantages of stable and reliable control, etc.

Description

technical field [0001] The invention relates to the field of iron and steel sintering, in particular to the problem of controlling the thickness of the mixed material layer on the sintering machine trolley during the sintering process. Background technique [0002] see figure 1 , is a schematic diagram of the iron ore sintering system. The ore tank group 10 includes a plurality of ore tanks, and each ore tank is equipped with a raw material, and the raw material includes fine iron ore, solvent, fuel and miscellaneous materials. The ore tank discharges various raw materials in a certain proportion to the mixing belt 11 below. The mixing belt 11 mixes various raw materials, sends them to the primary mixer 12 for primary water addition, and then transports them to the secondary mixing belt 13. The mixer 14 adds water for the second time to form a mixed material, which is then transported to the mixed material tank 17 through the first burning belt 15 and the second burning bel...

AI Technical Summary

Problems solved by technology

However, in actual use, the sintering machine often has operational failures. When the exhaust fan (not shown in the figure) below the sintering machine trolley 19 fails, the ignition does not stop, and the temperature of the ignition furnace accessories is very high. Burn out the layer thickness detection instrument, the price of the layer thickness detection instrument is very expensive, frequent replacement will increase the production cost of the manufacturer

[0006] After the layer thickness detection instrument is damaged, the system will not be able to obtain the layer thickness parameters of the mixture, and cannot effectively control the layer thickness of the mixture
