Embodiment 1

[0044] combine Figure 12 As shown, the detection method of a kind of iron ore powder assimilation reaction temperature and assimilation reaction speed of the present invention utilizes the detection device that is provided with electrode to detect the electric signal and temperature in the assimilation reaction process of iron ore powder sample 140 in the heating process. In the case of time change, the assimilation temperature and the time t required for the reaction process are judged by the change of the electrical signal, and then the assimilation reaction rate is calculated by using the time t and the distance δ between the electrodes. The specific process is as follows: first prepare the sample, cover the iron ore powder sample 140 on the calcium oxide tablet 130 of the detection device, and set the electrodes inside the calcium oxide tablet 130; The first detection unit and the second detection unit detect the electrical signal and temperature change over time during t...

Embodiment 2

[0089] combine Figure 5-11 As shown, the content of this embodiment is basically the same as that of Embodiment 1, and the difference is that a device for detecting iron ore powder assimilation temperature and assimilation reaction speed of this embodiment also includes a reaction timer 310, and the reaction timer 310 is connected with the assimilation reaction speed. The control processing unit 400 is electrically connected, and the reaction timer 310 times the reaction process, so that the time taken for the iron ore powder sample 140 and the calcium oxide tablet 130 to react to the third electrode 230 can be known, and further by calculating the time between the electrodes. The ratio of the distance between them and the time taken for the reaction gives the assimilative reaction rate. In the process of detecting the assimilation reaction in this implementation, when the temperature measurement part a222 detects that the temperature rises to 1150 ° C, the timer 300, the det...

Abstract

The invention discloses a detection method for iron ore powder assimilation reaction temperature and assimilation reaction speed, belonging to the technical field of iron ore powder sintering. A detection method of iron ore powder assimilation reaction temperature and assimilation reaction speed of the present invention uses a detection device equipped with electrodes to detect the electrical signal and temperature change with time during the assimilation reaction process of iron ore powder sample , judge the assimilation temperature and the time t required for the reaction process through the change of the electrical signal, and then use the time t and the distance δ between the electrodes to calculate the assimilation reaction rate. The invention provides a detection method for iron ore powder assimilation reaction temperature and assimilation reaction speed, which can accurately detect the iron ore powder assimilation temperature and assimilation reaction speed.

Description

technical field [0001] The invention relates to the field of iron ore powder sintering, in particular to a detection method for iron ore powder assimilation reaction temperature and assimilation reaction speed. Background technique [0002] Metallurgical sintering is to put iron-containing raw materials (iron ore powder), fuel (coal powder, coke powder), solvent (quicklime, limestone), etc., into granules after adding water, and put them on the sintering equipment. The process of igniting the fuel in the mixture, melting the easily soluble substances to produce a liquid phase, adhering to the surrounding insoluble substances, and condensing into blocks after cooling is called sintering. The sintering process has a direct and important impact on the output and quality of sintering production. Therefore, the sintering process should not only ensure the smooth operation of blast furnace production, but also increase production, and save energy and reduce consumption during prod...
