Description

本発明は、廃棄物の処理方法に関し、詳しくは、鋼線で結束されていた故紙を再生紙の原料にするため溶解したときに残る鋼線の廃棄物と、他の鋼材廃棄物とを一体化して、電気炉製鋼のスクラップ原料として利用可能なブロックとする方法に関する。 The present invention relates to a method for treating waste, and more specifically, a waste of steel wire remaining when it is melted in order to use waste paper bound with steel wire as a raw material for recycled paper, and other steel waste are integrated. The present invention relates to a method of making a block that can be used as a scrap raw material for electric furnace steelmaking.

パルプ資源は、回収再利用が可能な資源としては、高い回収率をもって利用されている資源であるが、これまで鉄鋼業とはあまり関連がなく、わずかに高炉に吹き込んで熱源として利用することが提案された（特許文献１）程度である。高炉への吹き込みは、故紙を粉砕し、それと粒状の廃プラスチックとを混合して、燃焼性および気送性を高めることによって可能になるとのことである。
特開２００２−３１３１３ Pulp resources are resources that can be recovered and reused with a high recovery rate, but have not been so much related to the steel industry so far, and can be used as a heat source by being slightly blown into a blast furnace. It is about the proposed (Patent Document 1). Blowing into the blast furnace is possible by crushing the waste paper and mixing it with granular waste plastic to increase flammability and air transport.
JP 2002-31313 A

一方、故紙の回収に当たっては、取扱いの便宜のため、一定量の故紙を「番線」と呼ばれる太い鋼線で結束することが一般に行なわれている。再生紙を製造するには、この故紙の束を水中に投入して溶解させる。するとパルプ分は水中に分散し、溶解しない番線が、場合により含まれている夾雑物とともに残る。残ったものは表面にパルプが絡んだ番線であって、これまで利用の途がなく廃棄するほかないが、廃棄には、それに伴って、処分場や費用の問題がある。 On the other hand, when collecting waste paper, for the convenience of handling, a certain amount of waste paper is generally bundled with a thick steel wire called a “number wire”. To produce recycled paper, this waste paper bundle is poured into water and dissolved. Then, the pulp content is dispersed in water, and the wire that does not dissolve remains with the impurities contained therein. What remains is a wire with a pulp on the surface, and it has been used for a long time. However, there are problems with disposal sites and costs.

発明者らは、この故紙の結束に使用されていた番線が良質の鋼からなることに着目し、電気炉製鋼のスクラップ原料として利用することを企てた。しかし、表面にパルプが絡んだ番線は嵩高であって、スクラップ原料の電気炉装入に使用されている電磁クレーンで吊り上げることができないという不便さがあって、直接電気炉に入れることができない。 The inventors paid attention to the fact that the wire used for binding the waste paper is made of high-quality steel, and attempted to use it as a scrap raw material for electric furnace steelmaking. However, the wire with the pulp entangled on the surface is bulky, and there is an inconvenience that it cannot be lifted by an electromagnetic crane used for charging an electric furnace of scrap raw materials, so it cannot be directly put into an electric furnace.

本発明の目的は、上述した、故紙の結束に使用されていた番線を電気炉製鋼のスクラップ原料として利用することを可能にし、資源の有効な再利用を実現するとともに、廃棄物の処分場や費用の問題を解消した廃棄物の処理方法を提供することにある。 The object of the present invention is to make it possible to use the above-described wire used for bundling of waste paper as a scrap raw material for electric furnace steelmaking, to realize effective reuse of resources, The object is to provide a waste disposal method that eliminates the cost problem.

上記の目的を達成する本発明の廃棄物の処理方法は、鋼線で結束されていた故紙を再生紙の原料にするため溶解したときに残る鋼線の廃棄物と、他の鋼材廃棄物とを、鉄分が全体の重量の過半を占めるように混合し、混合物を少なくとも二方向からプレスすることにより一体化して、電気炉製鋼のスクラップ原料として利用可能なブロックとすることからなる。 The waste processing method of the present invention that achieves the above-mentioned object includes a waste of steel wire that remains when it is melted in order to use waste paper bound with a steel wire as a raw material for recycled paper, and other steel material waste. Are mixed so that the iron content occupies a majority of the total weight, and the mixture is integrated by pressing from at least two directions to form a block that can be used as a scrap raw material for electric furnace steelmaking.

本発明の処理方法により廃棄物を処理すれば、コンパクトに固められた、一辺数十センチの立方体ないし直方体状のブロックが形成される。このブロックは電磁クレーンで吊り上げることができるから、輸送および電気炉への装入が容易である。番線の周囲に絡んでいたパルプや夾雑物は、電気炉製鋼の過程で燃焼し、またはスラグ中に入って除去されるから、製鋼作業には実質的な影響を与えない。プレス作業の設備は、さしたる場所や費用を要するものではなく、故紙の溶解を行なうプラントの近傍に建設することができ、そこへ他の鋼材廃棄物を運びさえすれば、本発明の処理方法は簡単に実施できる。このようにして、鉄鋼資源の有効な再利用が実現するとともに、廃棄物の処分場や廃棄費用の問題が解消する。 When the waste is treated by the treatment method of the present invention, a cube or a rectangular parallelepiped block having a side of several tens of centimeters is formed. Since this block can be lifted by an electromagnetic crane, it is easy to transport and load into an electric furnace. Pulp and foreign matter entangled around the wire are burned in the electric furnace steelmaking process or are removed by entering the slag, so that the steelmaking operation is not substantially affected. The press work equipment does not require much space and cost, and can be constructed in the vicinity of the plant where the waste paper is melted. As long as other steel waste is carried there, the treatment method of the present invention can be performed. Easy to implement. In this way, effective reuse of steel resources is realized, and the problem of waste disposal sites and disposal costs is solved.

他の鋼材廃棄物としては、鋼板、鋼棒、形鋼などの基礎製品を製造する際に、またはそれらを加工して製品を製造する際に発生する、「新断（しんだち）」と呼ばれる裁断屑が好適である。用済みのドラム缶やブリキ缶などの廃棄物もまた、他の鋼材廃棄物として有用である。これらの材料を、鉄分が全体の重量の過半を占めるように混合する理由は、ひとつは、故紙を結束していた鋼線は単独でプレスしても一体化することが困難であるか、または一体化できても崩れやすいが、他の鋼材廃棄物を組み合わせることにより強固なブロックにすることができるということであり、いまひとつは、鉄分が過半量、好ましくは６割以上を占めることにより、電磁クレーンで吊り上げることができ、ブロックの取扱いおよび電気炉への装入が容易に行なえるからである。 Other steel waste is “new sashichi” that occurs when manufacturing basic products such as steel plates, steel bars, and shaped steel, or when processing them to manufacture products. A so-called cutting waste is preferred. Wastes such as used drums and tin cans are also useful as other steel wastes. The reason for mixing these materials so that the iron content occupies a majority of the total weight is that the steel wire that bundles the waste paper is difficult to integrate even if pressed alone, or Even if it can be integrated, it tends to collapse, but it can be made into a solid block by combining other steel wastes. The other is that the iron content is more than 60%, preferably more than 60%. This is because it can be lifted by a crane, and the handling of the block and the charging into the electric furnace can be easily performed.

故紙を結束していた鋼線の廃棄物と他の鋼材廃棄物と配合したものをプレスする作業は、たとえば図１に示すように実施する。図１において、型枠（２）内に投入された配合材料（１）は、ピストン（３，４）により縦・横二方向からプレスされ、それに伴う変形で相互に絡み合う。ピストンが波線の位置から実線の位置に進んだところで、上下の方向、図でいえば紙面に直角な方向においてもピストンで押圧して、三方向からプレスすることが好ましい。形成するブロックは、実際上は、一辺が５０〜６０cmのほぼ立方体形状で、重量がほぼ３００kg内外のものが好適である。 The operation of pressing the steel wire waste that has been bundled with the waste paper and the other steel material waste is performed as shown in FIG. 1, for example. In FIG. 1, the compounding material (1) thrown into the mold (2) is pressed from both the longitudinal and lateral directions by the pistons (3, 4), and is entangled with each other due to the accompanying deformation. When the piston advances from the position of the wavy line to the position of the solid line, it is preferable to press from the three directions by pressing with the piston also in the vertical direction, in the direction perpendicular to the paper surface in the figure. In practice, the block to be formed is preferably a substantially cubic shape having a side of 50 to 60 cm and a weight of approximately 300 kg.

故紙の溶解処理を行なうプラントで発生した、鋼線にパルプが絡んだ廃棄物を４２０kg、鋼板の加工工場で発生した裁断屑を８０kg、図１に示したピストンをそなえた型枠の中へ、１回にそれぞれ約２１０kgおよび約４０kgずつ、２回に分けて交互に投入し、まず水平の二方向からプレスし、続いて垂直にプレスした。縦・横が約６０cmで高さが約７０cmのブロックが得られた。この廃棄物ブロックの重量は５００kgで、その中の鉄分は、重量で約５０％を占めていた。このブロックは強固で、電磁クレーンによる取扱いおよび電気炉への装入に支障がなかった。 Into a form with 420 kg of waste generated in a waste paper melting plant and pulp tangled in steel wire, 80 kg of cutting waste generated in a steel plate processing factory, and the piston shown in FIG. About 210 kg and about 40 kg each at a time were alternately charged in two portions, first pressed from two horizontal directions, and then pressed vertically. A block having a length and width of about 60 cm and a height of about 70 cm was obtained. The waste block weighed 500 kg, and the iron content thereof accounted for about 50% by weight. This block was strong and had no trouble in handling with an electromagnetic crane and charging into an electric furnace.
