本発明は鉄鉱石のベツデイング方法に係り、特
に均一性に優れた鉄鉱石のベツデイング方法に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for bedding iron ore, and particularly to a method for bedding iron ore with excellent uniformity.
溶鉱炉装入物は物理的にも化学的も均一性が要
求される。このために多数銘柄の鉄鉱石を多層状
に薄く積付けるベツデイングが広く実施されてい
る。 Blast furnace charges are required to be physically and chemically uniform. For this reason, bedding, in which many brands of iron ore are stacked thinly in multiple layers, is widely practiced.

されて落下撒布される。すなわち第１図に示す走
行方向のブームコンベヤー４から鉄鉱石６が落下
すると粒度の大きなものは左側に、粒度の小さな
ものは右へ落下する傾向がある。 In the conventional bedding method, as shown in Fig. 1, ore 6 falls from a boom conveyor 4 that moves along a bedding yard while keeping an angle close to perpendicular to the longitudinal direction of the ore bed 2 to perform bedding. ing. The ore 6 does not fall uniformly from the discharge end 8 of the boom conveyor 4 into the ore bed 2, but is distributed depending on particle size, viscosity, amount, specific gravity, etc. That is, when iron ore 6 falls from the boom conveyor 4 in the traveling direction shown in FIG. 1, those with large grain sizes tend to fall to the left, and those with small grain sizes tend to fall to the right.
すなわち鉄鉱石ベツド２の中央点積付けが守ら
れず、かつ成分偏析および粒度偏析が発生しやす
い。 That is, the central point stacking of the iron ore bed 2 is not maintained, and component segregation and particle size segregation are likely to occur.

効果があがつていない。 For this reason, an improvement is being considered in which the falling trajectory is adjusted using a hanging baffle plate 10 as shown in FIG. As a result, there is component segregation as shown in FIG. 3, and sufficient effects are not achieved.
第３図は鉄鉱石ベツドの巾方向断面のSiO2％

変動がある。 Figure 3 shows SiO 2 % in the cross section of the iron ore bed.
This shows the segregation, which varies from slightly less than 3% to slightly less than 7%.
本発明の目的は、前記の従来技術の問題を解消
し、優れた均一性を示す鉄鉱石のベツデイング方
法を提供するにある。 SUMMARY OF THE INVENTION An object of the present invention is to solve the problems of the prior art described above and to provide a method for bedding iron ore that exhibits excellent uniformity.

積付けることを特徴とする鉄鉱石のベツデイング
方法である。 The gist of the present invention is as follows. That is, in the bedding of iron ore, the ore is stacked so that the falling direction of the ore at the discharge end of the conveying and stacking device is made to coincide with the stowing progress direction of the ore bed, and the falling width of the ore is in the center of the ore bed. This is a betting method for iron ore.

た。 The inventors of the present invention have conducted various research studies to prevent segregation, and have found that if the falling direction of ore and the loading direction are made the same, even if the falling trajectory changes, the falling trajectory will change depending on the particle size. They also completed the present invention by paying attention to the fact that segregation in the cross section of ore beds disappears and does not occur.

ベツド２は一定品質となる。 The method of the present invention will be explained with reference to the drawings. FIG. 4A is a front view showing the method of the present invention, and FIG. 4B is a side view thereof. The ore falling direction at the discharge tip 8 of the stowage conveyor 12 is made to coincide with the stowage advancing direction, and the fourth
As shown in the side view of FIG. B, the ore is stacked so that the width of the ore fall from the discharge tip 8 is at the center of the ore bed 2. In this case, the segregation due to differences in the falling trajectories of the ore 6 is automatically equalized by moving the falling point in the loading direction of the ore bed 2, and the ore bed 2 has a constant quality.

おける偏析は発生しなかつた。Embodiment 1 FIG. 5 shows a loading device in which a tip conveyor 14 is installed. The ore 6 conveyed by the boom conveyor 4 passes through the tip hopper 16 and falls onto the ore bed 2 by the tip conveyor 14. In this case, the conveyance direction of the boom conveyor 4 is changed by 90 degrees by the tip conveyor 14, so that the direction in which the ore falls and the direction in which the ore bed 2 is loaded coincide with each other. As a result, segregation within the cross section of the ore bed 2 did not occur.

6B is a front view thereof, and FIG. 6B is a side view thereof, in which the stowage conveyor 12 is mounted on a pedestal 20 running on rails on pedestals 18 disposed at both ends of the ore bed 2. In this case, the transport direction of the stowage conveyor 12 coincides with the falling direction and the stowage direction of the ore. There was no segregation within the cross section of the ore bed 2, and the quality was uniform.
