- the present invention relates to a technique for effectively utilizing shot meal generated when shot blasting is performed on an iron-based metal.
- Shot lees generated when a shot brass is applied to an iron-based metal generally contains about 75 to 95% by weight of an iron-based metal powder and used shot balls (steel balls). For this reason, the shot residue can be an effective resource as a steelmaking raw material. However, this shot cake is easily ignited and scattered. In addition, since it contains a large amount of shot balls, it is difficult to perform solid molding by compression molding or the like. Therefore, it is inconvenient for handling such as transportation and storage, and it is disadvantageous in terms of technology and cost to reuse it. Therefore, the actual situation is that shot meal is landfilled as industrial waste.
- the present invention has been made in view of the above problems, and has been made for a steelmaking raw material capable of effectively reusing shot residue.
- Object of the present invention is to provide a plywood and a method for manufacturing the same.
- a prequette for a steelmaking raw material of the present invention for achieving the above object is a dried prequette containing an iron-based metal. It is obtained by solidifying with an auxiliary agent.

It is easy to handle. In addition, since it is a dry solid, there is no danger of bumping or soaring and discharging even if it is put into the blast furnace as it is. The force is over 90% by weight Since a large number of shot balls composed of pure iron are included, the amount of reducing agent used during steelmaking can be reduced. Therefore, the shot residue can be reused as a high-quality raw material for steelmaking, which contributes to environmental protection and reduces the disposal cost of the shot residue.
- the shot balls are bonded to each other via an iron-based metal powder impregnated with the solidification aid. As a result, shot balls that have been difficult to combine

- the steelmaking raw material prequette containing an oil component preferably contains 5 to 25% by weight of shot lees. Thereby, appropriate bulk density and mechanical strength can be ensured. In other words, if the shot meal content is less than 5% by weight, the bulk density becomes small, and depending on the type of the blast furnace, the prique may not fall smoothly when charged into the blast furnace. Further, when the shot meal exceeds 25% by weight, when the shot meal is unevenly distributed, the partial force of the shot meal which is unevenly distributed in the pricket is easily broken.
- the shot lees are preferably steel shot balls.
- the shot meal generally contains steel shot balls and powder

There is no need to grind finely. Therefore, it is possible to easily and inexpensively produce a prequette for a steelmaking raw material. [0014] In the second method for producing a pricket, it is preferable that the shot meal is mixed in an amount of 10 to 30% by weight.
- the amount of the shot residue in the flocculent aggregate is less than 10% by weight, it is difficult to obtain a bulky bulk plywood. Further, if the amount of the shot residue in the flocculent aggregate exceeds 30% by weight, it is difficult to solidify the shot residue, and when the shot residue is unevenly distributed, the partial force of the skewed scattered prey is likely to be broken.
- the second method for producing a plywood it is preferable to use a steel shot ball as the shot residue.
- the content of iron oxide is reduced, so that a prequette more suitable as a raw material for steelmaking can be obtained.

It is preferable to carry out this curing for about 2 days because the contained water can be surely removed. In the curing, the air may be blown at room temperature or cooled to rapidly cool the air.
- the precket A is a porous material obtained by solidifying the brittle molded product F, the moisture content can be easily and reliably removed by curing. For this reason, there is no danger that bumping will occur or dance, and it will go up and be discharged even if it is put into the blast furnace as it is.
- the briquette A since the content of shot lees S in briquette A is 5 to 25% by weight, the briquette A has appropriate bulk density and mechanical strength. That is, it is required that the prequette A for the steelmaking raw material fall smoothly without soaring when charged into the blast furnace. For this reason, depending on the type of blast furnace, the bulk density may be required to be 0.2 or more, but if the amount of shot cake in briquette A is less than 5% by weight, this requirement may not be satisfied. You. Further, when the shot cake in the briquette A exceeds 25% by weight, when the shot cake is unevenly distributed in the briquette A, the partial force of the shot cake is easily broken.

- it is possible to remove the influence of the spring knock and thereby to solidify the solidified prequette A. Can be easily obtained.
- ground swarf containing 0.2% by weight or more of carbon ground swarf of bearing steel can be mentioned.
- a shot ball having a used shot ball and a powder containing oxidized iron powder is used as the shot lees S. You may use what was done. In this case, since the content of the iron oxide in the prequette A is reduced, the amount of the reducing agent used during steelmaking can be reduced accordingly. For this reason, it becomes more suitable as a raw material for steelmaking raw materials.
- the shape of the pricket A has a rounded edge such as an egg shape, an almond shape, a rugby ball shape, and the like. It may be almost in the shape of a pillow, with the thickness gradually increasing from the part toward the center (see Fig. 3).
