Description
Technical Field
The invention relates to a pellet production process in steel smelting, in particular to a pellet raw material mixing degree detection device and a detection method thereof.
Background
In recent years, along with the exhaustion of high-quality lump ores, fine ore and ultrafine ore become main raw materials for iron making, and the pellet process is rapidly developed due to the advantages of the pellet process in the aspects of agglomeration of fine ore and ultrafine ore iron ore. On the premise of stable pellet process conditions, the quality of green pellets mainly depends on the mixing effect of raw materials, and the better the mixing effect is, the better the quality of green pellets is. At present, the mixing effect of raw materials is greatly improved due to the fact that the vertical type intensive mixer is introduced into a ball process, but the mixing uniformity detection of the ball raw materials is seriously delayed from actual production, and real-time on-line detection and automatic control cannot be realized, so that the development of a set of on-line detection technology for the mixing uniformity of the ball raw materials is particularly urgent to realize the intellectualization of the intensive mixer. At present, methods for detecting the mixing uniformity of materials by different industries, different fields and different raw materials are not the same. The variation coefficient CV (%) of the mixture is usually calculated by sampling, detecting and tracking the difference of a certain index in each sample of the mixture, and the variation coefficient is used for representing the uniformity degree of the detected material, and generally, the smaller the variation coefficient value of the detected index in each sample is, the higher the uniformity of the mixture is.
At present, two methods exist for detecting the mixing degree of the pellet raw materials, one method is a fluorescent powder method, fluorescent powder is added into the pellet raw materials and enters a mixer for mixing uniformly, the cross section of the mixed materials is observed, and the mixing degree of the pellet raw materials is judged by observing the distribution of the fluorescent powder on the cross section. The method can intuitively feel the mixing condition of the pellet raw materials, but the method can not perform quantitative analysis, only judges images, and has serious hysteresis, so that the method can not realize the online detection of the mixing uniformity of the pellet raw materials. The other method is to judge the mixing degree of the pellet raw materials in a fuzzy way through the using amount of bentonite, the balling performance of the mixed materials and the proceeding condition of the subsequent process, and the method can not judge the mixing uniformity of the pellet raw materials accurately and instantly and can not guide the production in time. Therefore, developing a set of on-line detection technology for mixing uniformity of pellet raw materials is particularly urgent to realize the intellectualization of the intensive mixer.

2. The overall device is small in size, with approximate dimensions capable of being as small as 400mm by 600mm. The transportation and the installation are convenient, and large-scale carrying equipment is not required for maintenance.
3. The driving power is low, and the energy consumption is low.
The invention can combine the vertical intensive mixer which is successfully applied to the pellet process raw material treatment in the metallurgical industry, realizes the intellectualization of the pellet raw material mixing system, ensures that the mixing system operates under the optimal parameters, and is a great breakthrough of the industry technology. The method can obviously reduce the energy consumption and material consumption of the raw material treatment process, improve the pellet quality, reduce the production cost and has great significance for the technical progress of the industry.
