Embodiment 1

[0023] Example 1, such as figure 1 shown.

[0024] exist figure 1 Among them, 1 represents the sintering trolley and its sintering mixture. 2 is an arrow representing the moving direction of the sintering trolley. The 3rd is the blowing main pipe, which is a round pipe shown in the figure, and it can also be a rectangular pipe or other special-shaped pipes. 4 is the spout made on the blowing main pipe 3, specifically to the present embodiment, this spout is a long slit with a width of 2.5-3 millimeters, but it does not rule out that it adopts other forms. 5 is the flow line which shows the airflow ejected from the nozzle 4. 6 is a blanking slide plate representing the sintered mixture. 7 represents the sintered mixture in the falling process. 8 represents the streamline of the sintered mixture 7 in the falling process. 9 is a water mist injection pipe, which adds an appropriate amount of moisture to the surface of the sintered mixture through the water mist nozzle. ...

Embodiment 2

[0027] Example 2, such as figure 2 shown.

[0028] The present embodiment has carried out a little change on the basis of embodiment 1: replace the drop slide plate 6 in embodiment 1 with multi-roll distributor 10; At this time, the distance L between the spout 4 and the lower edge of the multi-roll distributor 10, which is the feeding mechanism for the sintered mixture, can be determined according to 120 mm.

[0029] For the rest, refer to the relevant description of Embodiment 1.

Abstract

The invention discloses a method for reducing water of sintered mixture, which belongs to the technical field of sintering process in the metallurgical industry. The main technical problem to be solved by the present invention is to reduce the moisture in the sintering mixture and thereby reduce the energy consumption of the sintering process. The basic technical solution of the present invention is: a water-reducing method for sintered mixture, which includes the process of blowing the sintered mixture in the process of falling through the nozzle and using wind force to make it particle size segregated, characterized in that: the sintered mixture The moisture content is reduced by at least 3.6%. The invention is not only suitable for newly designed sintering machines, but also suitable for the transformation of existing sintering machines.

Description

technical field [0001] The invention relates to a water-reducing method for sintering mixture, which belongs to the technical field of sintering technology in the metallurgical industry. Background technique [0002] Sintering is one of the key process links in the metallurgical industry. During the sintering operation, a thin layer of primer is usually laid on the grate bar or grate plate of the sintering machine trolley, then the sintering mixture is filled, and then ignited from the upper surface, and under the action of the induced draft fan, the combustion The belt moves down continuously to finally complete the sintering process. [0003] In order to meet the needs of mixing, granulation and sintering processes, about 7% of water usually needs to be added to the sintering mixture and mixed evenly. During the sintering process, these moistures formed an obvious over-wet zone below the combustion zone. [0004] The main problem that prior art exists is: [0005] 1. I...
