The present invention relates to a method of stacking blended light using a stacker, and more particularly, to a method of stacking blended light using a stacker for controlling a blending light stacker to shorten a head head traveling distance according to a change in height of a blended light stacking pile. .

In general, steel mill raw materials are mixed with iron ore using a blending facility in a blending process in which iron ores are mixed. In such a blending operation of iron ore, the iron ore component is used in an importing country, that is, currently used in a steel mill. Since the ingredients of iron ore imported from Australia, Canada and Brazil, which are the main importers of iron ore, are varied, blending is performed to keep the iron ore constant.

For example, the content of SiO2 must be kept constant during de-silicon treatment, so that the amount of slag generated by constant supply of flux required for de-silicon treatment can be kept constant. It is important to keep.

Meanwhile, in the process of producing the blended ore, which is the sintered raw material ore manufactured in the raw material processing process, the iron ore and the subsidiary material of each blend are deposited on the blended ore stacking yard with the blending ore stacker, and such a stacker is schematically illustrated in FIG. 1. .

As shown in FIG. 1, the stacker 1 moving in the stacking yard 4 forms a stack pile of the blending light 3 manufactured by reciprocating the stacking yard 4 at approximately 250 to 300 m. In accordance with this, the stacking is carried out while varying the height in approximately 1 to 4 steps 3a, 3b, 3c, and 3d.

And the stacker 1 as described above is to be deposited in the stacking yard (4) to be deposited in the stacking light (3) when the stacking piled on the stacking yard 4 through the belt conveyor (2a) installed in the boom (2) The ore dispersing device 6 is installed under the support beam 5a of the tension adjusting device 5 provided at the tip end of the belt conveyor 2a of the boom 2 so that the stacked blending light 3 is accumulated and stacked.

In FIG. 2 and FIG. 3 to be described later, the same reference numeral 3 as in FIG. 1 shows the blending light.

And, as shown in Figure 2, the branding reclaimer 10 is a mobile device installed on the running rails (17a, 17b), unlike the general reclaimer is a remote operation type, unmanned installation.

This branding reclaimer 10 is composed of a double bucket wheel (double bucket wheel), as shown in Figure 3, the bucket wheel 13, a plurality of buckets 14 are mounted on the outer peripheral surface It is.

The bucket wheel 13 equipped with the plurality of buckets 14 is rotated at a fixed height and at the same time, the ore flowed by the harrows 12a and 12b while collecting transversely is collected into the buckets 14. To be loaded onto a belt conveyor in the cabin and fed to the sintering process.

The branding reclaimer 10 as described above, when the traverse is completed, the traveling for 4 seconds (100mm) is made, and the repetition operation is performed in the dispensing method that the traverse progresses again in the opposite direction.

However, the stacking method of stacking the blending light of the stacker according to the related art, the ore and auxiliary raw materials of each brand stacked by the stacking method of the stacking method of reciprocally stacking a designated section and changing only the height of the pile pile from the initial pile to completion Build up different brands of piled ore.

In this loading method, as shown in FIG. 3, the component instability is generated, and the blending reclaimer 10 is rebranded and processed into the next loading file. That is, as shown in FIG. 3, a rebranding file is generated and needs to be rebranded and processed by the rebranding reclaimer 10.

When the amount of unstable rebranding occurs, for example, about 2000 tons, the dispensing time is about 1 to 2 hours when dispensing to the branding reclaimer 10, which greatly affects the maintenance of sinter bin inventory. When it is difficult to maintain, since it directly granulates into a sintering bin, there is a great difficulty in stabilizing components in the sintering process.

The present invention was created in order to solve the above problems, the re-branding file is not generated, and the blending light storage method using a stacker to contribute to the stable operation of the sintering process by adding the blending light of a uniform component The purpose is to provide.

In the stacking method of stacking light using the stacker of the present invention for achieving the above object, in the method of stacking the blending light using a stacker for stacking the blending light, the total stacking amount when the blending light is stacked with the stacker To calculate the initial driving distance, and the file completion height of the blended light, to determine the value of the total layer by applying the same value to the entire layer divided by the total height of the pile to the entire layer, and the initial driving distance and When the boom up tilt for starting the pile operation at the initial pile height and detecting the pile completion of the initial pile height is operated, the boom up tilts to the next height, and the mileage is shortened by the linear distance with respect to the pile height. It is characterized by running.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

4 and 5 schematically show the pile loading degree and the pile discharging degree to which the blending light loading method using the stacker according to the present invention is applied, respectively.

Referring to each of the drawings, in the stacking light stacking method using the stacker according to the present invention, the stacking (1) to calculate the total stacking amount when the blending light (30) when the initial running distance (L) is specified.

The pile height H of the blending light 30 is equally applied to the entire layers H1 to H6 by dividing the total height by the total layers H1 to H6 to the entire layers H1 to H6. Set the value.

In addition, when the boom up tilt to start the loading operation to the initial driving distance (L) and the initial pile height (H1), and is installed on one side of the stacker (1) to detect the completion of the pile pile of the initial pile height (H1) height , Ascends to the next height H2.

The travel distance is shortened by the straight distance L1 for each pile height from the initial travel distance L and travels.

In this way, the initial driving distance (L) starting from the initial pile height (H1) piles, each time the height value changes by one step from H1 to H6 in each floor, the mileage value of the initial mileage (L) is the initial driving Each time the floor changes in distance L, the driving distance is shortened to L1 to L5.

Therefore, when the pile is completed by the automatic control of the driving distance and pile height accumulated by the pile completion driving distance L0, the rebranding pile distance is not formed as in FIG. 3, and the blending light (as shown in FIGS. 4 and 5). Only the uniform component loading pile of 30) is formed.

As described above, the accumulation file of the blending light 30 formed of only a uniform component is obtained after the completion of the pile placement, and converts the new pile into the new head and the damage of the branding reclaimer 10 as shown in FIG. (harrow) (12a, 12b) parts coincide with the uniform blending light into the sintering bin from the start of dispensing without the head re-blending process.

As described above, the method of accumulating the blended light using the stacker according to the present invention has the following effects.

According to the height change of the pile pile of the blending light can shorten the head distance, and contribute to the stable operation of the sintering process by incorporating the blending light of uniform components into the sintering bin from the start of dispensing without the reheading process.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
