源有効利用の観点から、炉滓中の鉄分の回収と鉱滓の骨
材としての利用が行われている。Most of the blast furnace slag, converter slag, electric furnace slag, etc. generated in the iron and steel manufacturing processes were disposed of by dumping, but in recent years, from the perspective of reducing landfill sites and making effective use of raw materials, efforts have been made to recover the iron content in the furnace slag. Mine slag is used as aggregate.

で、ロッドミル。In the process of crushing the furnace slag, the iron content is recovered by magnetism as steel layer concentrate.
Furthermore, a rod mill is used for the purpose of increasing the iron content as a concentrate for iron and steel manufacturing.

自生粉砕ミルで磨鉱を行う工夫もなされている。Efforts have also been made to grind ore using an autogenous grinding mill.

そこで本発明者等は、上記塊状炉滓を効率良く粗割する
機械を開発すべ（，５００５ｍ以上の寸法で鉄分含有率

よう々結果を得た。Therefore, the inventors of the present invention aimed to develop a machine that can efficiently coarsely split the above-mentioned lumpy furnace slag.We conducted a test to apply compressive force to furnace slag with a size of 5005 m or more and a high iron content, and found the following results. We obtained various results.

（１）鉄分が銑の場合、鉄分含有率が１００ヂ近いもの

つた。(1) When the iron content was pig iron, iron content up to nearly 100 degrees was roughly divided from the gun itself and the slag involved. At this time, the slag that was attached to the pig iron and the slag that was caught in it were
It was distributed on the smaller side compared to the size of the coarsely cracked pig iron.

In addition, the steel was cracked due to thin parts of the steel itself, irregularities on the surface, and defects such as internal cavities.

（３）上記（１）　、　、（２）項で粗割された炉滓の
鉄分含有率は必ず上昇し、高いものは９０チを超えた。(3) The iron content of the furnace slag coarsely divided in items (1), , and (2) above always increased, and in some cases it exceeded 90%.

になるものと認められる。It is not homogeneous like cast steel or cast iron, but has many irregularities and sharp cracks on its surface, and contains many cavities and blow holes, which are often referred to as casting defects. . Therefore, if compression is applied to the metal in the furnace slag as in the test described in fil, stress concentration will occur on the surface and internal defects of the metal, and the compressive strength of the iron solid M will be affected by LL, Because the slag is involved in the raw metal, the larger the proportion of slag in the rough cutting 1i11, the smaller the force is required to roughly break the metal. It is recognized that this is the case.

されることが判明した。Furthermore, as shown in Figure 1, the compressive force applied during rough splitting is as follows: If the compressive force is applied in the direction of the arrow by bending the lumpy slag S at three points, the amount required to roughly split the lumpy slag S is The force is several minutes.
It has been found that most of the lumpy furnace slag with a size of 300 to 500 fins or more can be roughly broken or transformed to a size of 300 to 500 fins or less.

ある。The present invention was made in view of this point, and the iron content is as high as 50 to 60 inches or more, and the size of the iron content is as high as 30 inches.
It is an object of the present invention to provide an oscillating type coarse cracker capable of efficiently coarsely splitting or deforming large lumps of furnace slag of 0 to 500 or more.

の間に形成された徂’ＪｉＵ室である。One of the swing-type rough splitting machines of the present invention will be explained with reference to the embodiment shown in FIGS. The swinging +l'f1 splitting plate is tilted opposite to the rough splitting plate, and the swinging rough splitting plate 3 is fixed to a jaw 5 that swings back and forth while moving up and down using an eccentric shaft 4 as a fulcrum. has been done. The eccentric shaft 4 has its shaft end directly connected to the rotating shaft 4 (116), and is integrally connected to the rotating shaft 6. A V-boo 91 is fixedly attached to the rotating shaft 6, and the V-pulley 7 is connected to the output shaft of an electric motor (not shown). V belt 8 between the V pulley of
is mounted. Reference numeral 9 denotes a 'JiU chamber formed between the fixed rough dividing plate 1 and the swinging rough dividing plate 3.

つの波形状になされている。The opposing surface shapes of the fixed rough dividing plate 1 and the swinging rough dividing plate 3 are as follows:
It is formed into a wave shape in which peaks 11 and valleys 12 face each other in the radial direction of the entrance to the coarse splitting machine, that is, the entrance 10 at the upper end of the coarse splitting chamber 9. The number of ridges 11 on the surface of one coarsely divided plate is 1 to 3, and the number of ridges 11 on the surface of the other coarsely divided plate is 2 to 4. In this example, the number of ridges on the fixed rough dividing plate 1 is 3, and the number of ridges on the swinging rough dividing plate 3 is 4.
It is made into a wave shape.

、粗割でき々い塊状炉滓Ｓが多く発生するからである。The reason why the number of ridges 11 on the surface of one rough dividing plate is 1 to 3 and the number of ridges 11 on the surface of the other rough dividing plate is 2 to 4 is as shown in FIG. This is to roughly split S by applying compressive force in the form of three-point bending, and if the number of ridges 11 on the rough-splitting plate surface is larger than this, the compressive force due to three-point bending will not be reduced. This is because a large amount of hard lumpy slag S is generated.

Typical dimensions for bulk furnace slag of 0 mm or more are 500 x 75
If GX100 psnJ is considered, then the dimensions LXW of the entrance 10 of the coarse cracking chamber 9 that receives such a lumpy slag is 1
With this size, which is about 500 x 750 ma, most of the lumpy slag can be put into the coarse cracking chamber 9. Therefore, no matter what direction this lump-like furnace slag enters, the number of peaks 11 that are susceptible to bending force is a combination of two peaks and three peaks, as shown in FIGS. 4B, b, and e. This is 50QX750X
This shows an example of a 100O gourd block slag and L-1500mm, but if the block slag is placed vertically in the direction of the maximum side length of 1000m and placed in the rough-splitting chamber 9, the length will be L.
-j It can be reduced from 500 to 750. In this case, a combination of one mountain and two mountains may be used instead of a combination of two mountains and three mountains.

組合わせ、即ち谷と山の組合わせでも不適当である。On the other hand, if the general size of lumpy furnace slag of 300 to 500 +++ m or more is on the smaller side, it would be strange to consider a combination of 2 and 3 ridges as a combination of 3 and 4 ridges. However, increasing the number of slags more than this is not suitable for coarsely splitting lumpy furnace slag of 300 to 500 tan or more by causing bending due to compressive force. Even combinations with fewer valleys and peaks are inappropriate.

A wavy shape with successive trapezoidal peaks and valleys may also be used.

The 111S of the slag, which was reduced to ~500 ml or less and had a low iron content, was exfoliated and the iron content was reduced to 80.
It is raised above the coefficient μ and outputted from the outlet 13 by vl. Thus, the iron content is 5] with dimensions of 300 to 500 or more.
~60 pieces of lumpy slag S is continuously and efficiently coarsely cracked or deformed to a size of 300~500 m or less, and the iron content is increased to 80 mm or more.

２１５とした理由について説明する。That is, the dimension between the opposing fixed rough dividing plate 1 and the swinging rough dividing plate 3 at the outlet 13 at the lower end of the rough dividing chamber 9 is the same as that of the opposing fixed rough dividing plate 1 at the inlet 10 at the upper end of the coarse dividing chamber 9. The dimension between the plate 1 and the rocking rough dividing plate 3 is 115 to 215, and the rocking rough dividing plate 3 can maintain a constant compressive force on the back side of the rocking rough dividing plate 3. A hydraulic mechanism 14 that can retreat when a reaction force that overcomes the compression force is provided is provided.0 The dimensions of the outlet 13 of the rough splitting chamber 9 are set to 115 to 100 of the dimension of the inlet 100.
The reason why it is set to 215 will be explained.

口１００寸法の１１５〜２１５と決定したものである。The gap W at the entrance 10 of the coarse cracking chamber 9 is determined by the maximum supply arm of the block slag S. On the other hand, the gap W' at the outlet 130 is determined by the crushing ratio of the ingot, which requires a large pressure m+i force when 8i'I11 is in the block slag S. Generally speaking, it is said that the harder and higher the compressive strength, the smaller the crushing ratio.
Rough splitting room 9 where a test was conducted to roughly split the bullion using compressive force.
If the gap W' of the outlet 13 of the rough-splitting chamber 9 is (0,2 to 0.4)XW with respect to the gap W of the entrance 10 of It has been found. Based on this, in the present invention, the dimension of the outlet 130 of the rough-splitting chamber 9 is determined to be 115 to 215 of the dimension of the inlet 100.

The lumpy furnace slag S, which is 300 to 500 ff1m or more and has an iron content of 50 to 60% or more, which is input from the inlet 1o of the tuna, is shaken in the coarse cracking chamber 9 by the buried movement of the tuna 1. When the roughing plate 3 approaches the fixed roughing plate 1 side, the space in the roughing chamber 9 becomes narrower, compressive force is applied to the lumpy furnace slag S, and the hydraulic machine i4#
Pressure is generated in the 14 hydraulic cylinders 15. When the pressure of this hydraulic cylinder 15' is below the holding force of the hydraulic system and the lumpy furnace slag S,'lr:m is divided, the oscillating rough-splitting plate 3 moves away from the fixed rough-splitting &1 side. The slag descends due to gravity, is again subjected to the compressive force of the oscillating coarse-splitting plate 3, and is coarse-split.This is repeated several times until it reaches the outlet 13 of the coarse-splitting chamber 9.
If the size is smaller than the normal gap W', the liquid will be discharged through the outlet 13 and fall.

The oscillating coarse plate 3 retreats by the same amount, and the gap W between the outlet 13 widens. Therefore, the lumpy slag S falls under its own weight and is again subjected to the compressive force of the shaking MJhm plate 3.
One or more portions of the material are removed. The slag that cannot be roughly divided in this way is discharged through the outlet 13 and falls due to gradual deformation or partial peeling of the slag with low iron content.
