Embodiment Construction

[0032] First: define the cloth uniformity index θ i . Referring to Figure 1, the sintering mixture bed is equally divided into N (i=1, 2, ..., N) regions along the width direction of the sintering section, that is, the section is divided into N columns (vertical planes), and the width of the sintering mixture bed is considered There is no other segregation in direction except compactness. Assuming that the mass of the mixture in the i-th region is m i (kg), the average mass of the mixture in each equal area is

[0033] Definition: Cloth uniformity index θ of the i-th region i for:

[0034] Known from physics, m i =ΔV·ρ o ·(1-ε i ), m ‾ = ΔV · ρ o · ( 1 - ϵ ‾ )

[0035] In the formula: m i , --The mass of the mixture in the i-th region and th...

Abstract

The invention discloses an on-line testing method of cloth even condition of cloth bed in the sintering manufacturing course, which is characterized by the following: assembling multiple thermocouples among each waste gas bellow at middle back part of sintering machine and at each bellow evenly; forming the temperature testing array of the sintered waste gas; establishing the plane temperature field of waste gas temperature of sintering machine; obtaining the character information through analyzing on-line temperature field; proceeding quantitative estimation for cloth uniformity; providing and defining the uniformity index of the sintered cloth as well as the mathematical model of the index. The invention realizes the on-line quantitative analysis of uniformity condition of composite material bed, which provides criterion to control the sintering material on the machine.

Description

(1) Technical field [0001] The invention relates to an online detection method for the uniform state of the material bed in the sintering production process. (2) Background technology [0002] Whether the sintering mixture is evenly distributed on the trolley directly affects the output, quality and energy consumption of sintering ore. Uniform material distribution is one of the main goals of the automatic control of the sintering system. Due to the continuity and long lag characteristics of the sintering process, once the mixture is distributed to the sintering machine, it cannot be adjusted again. Whether the distribution is uniform can only be judged by the manual experience of the operator at the tail of the sinter bed, and the results of the analysis and judgment are fed back to the automatic control system. This feedback method of production result information seriously restricts the basic automatic control. performance of the system. [0003] The online monitoring o...
