Embodiment Construction

[0024] Preferred embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will understand the features and advantages of the present invention from the accompanying drawings and corresponding descriptions.

[0025] In the present invention, the sintered raw materials after batching are mixed twice and a certain amount of water is added each time they are mixed. Among them, adding water for the first time makes the water content of the mixture reach the target value set by the first time mixing and adding water. The amount of water reaches the target value set for the second mixing and adding water, which is beneficial to the pelletizing of the mixture, ensures good air permeability during sintering, and improves the output and quality of sintering ore.

[0026] In the present invention figure 1 A schematic diagram of the mixing and adding water system is shown in , which includes th...

Abstract

The invention relates to an automatic water mixing control system for sintering production, comprising a first-time mixer, a second-time mixer and a plurality of infrared moisture meters, wherein each infrared moisture meter comprises a first infrared moisture meter and a second infrared moisture meter, wherein the first infrared moisture meter is arranged on the outlet of the first-time mixer; and the second infrared moisture meter is arranged on the outlet of the second-time mixer. The automatic water mixing control system is characterized in that other infrared moisture meters are arrangedon a blending material bin, the original water content of sintering raw materials is obtained through summarization and measurement by other infrared moisture meters arranged on the blending materialbin to provide the reference basis of moisture control for the first-time water feed mixing of a next production process; and besides, the closed loop PID (Proportion Integration Differentiation) feedback control of water feed is respectively set on the first-time mixer and the second-time mixer.

Description

technical field [0001] The invention relates to a fine ore processing system used in iron and steel metallurgy, in particular to an automatic water mixing control system used in sintering production. Background technique [0002] Generally speaking, the fine ore processing system in the iron and steel industry is to first mix various powdery iron-containing raw materials into an appropriate amount of fuel and flux, then add an appropriate amount of water in batches, mix and pelletize, and finally use it on the sintering equipment. A series of physical and chemical changes occur in the material, and the powder ore particles are bonded into blocks. [0003] At present, belt-type exhaust sintering machines are widely used in production to produce sintered ore. The technological process of sintering production mainly includes the proportioning of sintering raw materials, that is, adding an appropriate amount of fuel and flux into powdery iron-containing raw materials and making...
