Problems solved by technology

Therefore, within the period (T-t, T), the finished products obtained by sintering cannot meet the requirements of the process
[0007] It can be seen from the above that the traditional finished product inspection has a large time delay, and cannot obtain the composition information of the finished product in time, and cannot adjust the mixture ratio in time, resulting in a relatively high defective rate and low quality of the sintered product

Embodiment Construction

[0047] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] The component forecasting device of the finished sintered ore product according to the present invention is set at the first assembly point, by obtaining the ratio of each mineral material in the mixed material falling on the mixing belt, and combining the percentages of various components in each mineral material The predicted value of the percentage content of various components in the finished sintered ore product is obtained by calculation.

[0049] refer to figure 2 , is the structural diagram of the component prediction device for the finished sintered ore product according to the first embodiment of the present invention.

[0050] see figure 1, set the junction of the mixing belt and the primary mixer 2 as the fir...

Abstract

The invention discloses a composition prediction device which includes: a mineral composition obtaining unit, a mineral mixture ratio obtaining unit and a composition prediction unit; wherein, the mineral composition obtaining unit is used for obtaining percentage content of each composition in each mineral material; the mineral mixture ratio obtaining unit is used for obtaining total cutting flux of each mineral kind and calculating mixture ratio of each mineral material in the mixed mineral material; the composition prediction unit is used for calculating a prediction value of the percentage content of each composition in the sinter product according with the mixture ratio of each mineral material in the mixed mineral material and percentage content of each composition in each mineral material. The invention also discloses a composition prediction method of the sinter product. The method and the device can predict the component of the sinter product and increase the sinter quality.

Description

technical field [0001] The invention relates to the field of iron and steel smelting, in particular to a composition prediction device and method for sintered ore finished products. Background technique [0002] refer to figure 1 , is the process flow diagram of the batching system of the sintering plant. [0003] The batching workshop of the sintering plant is equipped with several large ore tanks 1 along the mixing belt, which are used to store various materials required for sintering production, such as concentrate, fine ore, blast furnace return, fuel, flux, etc. Each ore tank 1 feeds to a mixing belt, and finally forms the mixed raw materials of 13 ore tanks 1 at the end of a mixing belt. The above is often referred to as the batching system. The batching system controls the discharge flow rate of each ore tank 1 in proportion according to the comprehensive delivery volume, and then controls the chemical composition of the sintered product. The raw materials on the ...
