不純物混入を避ける上で好ましい。[0008] As the above-mentioned metal cutting chips, steel-based chips, cast iron-based chips, or a mixture of both are used. On the other hand, the plastic waste material is preferably a polyolefin-based thermoplastic resin, for example, polyethylene, which is frequently used as interior and exterior materials for automobiles,
Polypropylene, polystyrene and the like are used. However, in the case where the surface of the plastic waste material is coated, it is preferable to use those in which the coating films are peeled in advance in order to avoid contamination with impurities.

The plastic waste is reused as a raw material or a molten material to be used, and at the same time, the plastic waste is reused as a heat source for melting or fuel for replacing a part of coke. That is, this claim 1
According to the invention described in (1), the charging of the raw material to the cupola and the charging of the heat source or the fuel are simultaneously achieved by charging the fuel briquette into the cupola.

ことを特徴としている。The invention described in claim 2 is the first invention.
In producing the fuel briquette for cupola described in (1), a plastic waste piece of a polyolefin resin and metal shavings are kneaded, and the mixture is solidified by a cold pressure molding process.

切削屑成分が増加した場合である。[0013] In terms of compressibility, metal cuttings are generally superior to waste plastic pieces. However, since the shape retention of compression also depends on the blending ratio of both, the compact is formed by cold pressing. What can be done is when the metal shavings component increases more than about 2: 1 as a ratio of metal shavings to plastic waste pieces.

法により成形固化させる。The reason why the plastic waste material is once melted is to make the mixing state of the metal cutting waste and the plastic waste material uniform, and in particular, as the mixing ratio of the plastic waste material to the metal cutting waste increases, the above-described cold state increases. Since it is difficult to solidify by pressure molding, in this case, it is molded and solidified by this method.

According to the construction method of the second aspect, since cold pressure molding is performed at room temperature without melting the plastic waste material, it is excellent in man-hour and cost.

源化を同時に達成できる効果がある。According to the first aspect of the present invention, as a fuel briquette for a cupola, a metal chip such as steel or cast iron is mixed with a crushed polyolefin-based plastic waste material piece or a molten plastic waste material. Since this is compression molded and solidified, metal cuttings are reused as raw materials or molten materials that are to be melted by melting, and at the same time, plastic waste is used as a heat source for melting instead of coke. Since the fuel is reused as a fuel, charging the above-mentioned fuel briquettes into the cupola makes it possible to simultaneously supply the raw materials to the cupola and the heat source or the fuel. There is an effect that the recycling of waste materials as fuel can be achieved at the same time.

In producing the above-mentioned cupola fuel briquette, a polyolefin-based plastic waste material is once melted, then the molten resin material and metal cutting chips are kneaded, and this is solidified by a pressure molding process. Compared with the production method according to the second aspect, the composition of the metal shavings and the plastic waste can be made more uniform or homogenous, and in particular, there is an advantage that the calorific property as fuel is stabilized.

宜設定される。The compression strength of the fuel briquette B after the compression molding is specified because the fuel briquette B is prevented from collapsing due to an impact during the transportation process or the charging of the fuel briquette B into the cupola.
This is to promote efficient heating or combustion while maintaining air permeability in the cupola. Also, fuel briquette B
The shape and size of are not limited to those exemplified above, and are appropriately set in consideration of the transportability and the air permeability and liquid permeability in the cupola.

May be directly charged into the kneading mixer 3 while being measured, and kneaded with the cutting waste. In this case, the labor for melting the plastic waste material can be omitted, and the manufacturing cost can be reduced accordingly.

In addition to the molten raw materials such as pig iron, steel scrap, old pig iron, and other fuels or coke and limestone as component adjusting materials, they are charged into the cupola from the charging inlet, and the cutting waste components contained in the fuel briquette B Is melted into molten metal as a casting raw material, and similarly, plastic waste material components are effectively used as a heat source fuel for melting, and the amount of fuel briquette charged is appropriately adjusted according to the ratio with the above-mentioned iron or coke. Adjusted. However, although fuel briquette B is used as a part of alternative fuel for coke, considering the maintenance of the height of bed coke in cupola and the effect on the quality of molten metal, the replacement amount is at most 25% of the added coke. It is desirable to be about.

As a part of the melt, it contributes to the dissolution of the raw material, while the cutting waste component dissolves and becomes a part of the molten metal.
