Definitions
- the present invention relates to a method for producing a metal briquette that can efficiently produce a briquette-like metal material having a shape that can be easily reused from, for example, a steel can or an aluminum can collected by recycling or the like.
- Patent Document 1 and Patent Document 2 a metal briquette having a shape excellent in handleability is manufactured from a steel can or aluminum can recovered by recycling or the like, and this is used in a steel mill or a foundry. It is widely used as a deoxidizer or the like.
- a method for producing metal briquettes a plurality of concave dies are placed and pressed into granular aluminum scraps and pressed into metal briquettes of a predetermined shape, and then metal briquettes are removed from the dies. The method of taking out is common.
- the present invention solves the above-mentioned problems, can ensure a sufficient strength of the briquette as well as being excellent in productivity, and can efficiently produce a metal briquette having low cost and excellent handleability. It aims at providing the manufacturing method of the metal briquette which can be manufactured.
- the method for producing a metal briquette of the present invention made to solve the above problems includes a step of heat-treating the recovered steel can and / or aluminum can to remove impurities, a step of crushing it to obtain a granular metal material, The step of compressing the granular metal material into a sheet-like briquette sheet in which a large number of briquettes are connected in a rosary shape via a connecting portion by a briquetting machine, and the obtained briquette sheet is divided at the connecting portion. And individual metal briquettes.
- This method is excellent in productivity and can secure a sufficient briquette strength.
- a pair of cylindrical cutter rolls each having a plurality of wedge-shaped cutting blades protruding at equal intervals on the outer peripheral surface are rotated in the reverse direction. It is preferable that the cutting is performed by causing the tips of the cutting blades to approach and separate from each other as the cutter roll rotates.
- This dividing method is preferable from the viewpoint of increasing productivity, and by pushing and cutting the connecting portion of the briquette sheet around the briquette body from the sheet-like briquette sheet in which a large number of briquettes are connected in a beaded manner through the connecting portions.
- the briquette sheet so that a burr portion generated by pushing off the connecting portion of the briquette sheet is left around the briquette main body, particularly at both ends. In this way, waste can be eliminated. Furthermore, it is preferable from the viewpoint of availability that the burr portion has a length of 1 to 5 mm. A metal briquette exhibiting excellent formability and handling properties can be obtained without any waste due to such division.
- both the steel can and the aluminum can that are recovered are in a required ratio even if they are treated separately depending on the use of the obtained metal briquette.
- FIG. 1 is a flowchart showing the manufacturing process of the present invention.
- the present invention will be described in more detail with reference to this flowchart.
- the raw material steel can and aluminum can for example, those collected by recycling or the like are used (step 21 in FIG. 1), and this is washed and used as necessary.
- the body of the metal can to be collected is made of steel and the lid is made of aluminum, it is preferably collected in a separated state, and of course, it may be a can made of steel alloy or aluminum alloy. is there.
- the collected steel can and / or aluminum can is heat-treated to remove impurities (step 22 in FIG. 1).
- Impurities such as printing paints and protective coating materials are present on the surface of the can, so that this can be removed to make a steel can or aluminum can substantially free of impurities. It is sufficient to stir in a heating apparatus such as about 400 to 500 ° C. under heating conditions.
- the heat-treated substantially impurity-free steel can and / or aluminum can taken out from the rotary kiln is crushed into small pieces by a general shredder machine or granulator to form a granular metal material composed of particles of a predetermined size or less.
- a general shredder machine or granulator to form a granular metal material composed of particles of a predetermined size or less.
- the granular metal material obtained in the above-described process is compressed into a sheet-like briquette sheet 3 in which a large number of metal briquettes 1 are connected in a rosary shape via connecting portions 2 as shown in FIGS. 2A and 2B, for example. Molding is performed (step 24 in FIG. 1).
- the molding speed can be increased as compared with the case of molding into individual briquettes, and sufficient briquette strength can be secured. Is played.
- the connecting portion 2 of the obtained briquette sheet 3 is pushed through the cutting blades 11a and 12a to form the metal briquette 1 (steps 25 and 26 in FIG. 1).
- a plurality of cutting machines are formed on a pair of cylindrical cutter rolls 11 and 12 that rotate in reverse to each other so as to form wedges and the tips approach and separate from each other.
- a cutting machine in which the cutting blades 11a and 12a are provided on the outer peripheral surface at regular intervals is used. The ends of the cutting blades 11a and 12a are sufficiently close to each other when the briquette sheet 3 is cut, and the briquette sheet 3 is pushed by the cutting blades 11a and 12a at the connecting portion 2 between the briquette bodies.
- the metal briquette 1 will be manufactured.
- the metal briquette 1 is compression-molded by a briquette machine (not shown), and comprises a briquette body 1a and a burr portion 1b generated by pushing the connecting portion 2 between the briquette bodies.
- the burr 1b preferably has a length of 1 to 5 mm. The reason for this is that if the length of the burr portion is less than 1 mm, the briquette bodies 1a, 1a adjacent to each other in the briquette sheet 3 are too close to each other, making it difficult to manufacture briquettes, and ensuring sufficient strength is difficult. This is because if the length is longer, handling of the briquette sheet 3 becomes difficult and the burr portion 1b is long and the utility value is lowered.
- the metal briquette manufacturing method according to the present invention is excellent in productivity, can secure sufficient briquette strength, and is excellent in handling at low cost. A metal briquette can be manufactured efficiently.
- FIG. 2B is a side view of the briquette of FIG. 2A.
- FIG. 2 It is a front view which shows the push-off process of a briquette sheet.

Abstract
Description
また、金属ブリケットの製造方法としては、複数個並んだ凹状の金型内に粒状化したアルミニウム屑等を投入およびプレスして所定形状の金属ブリケットに圧縮成型し、その後、金型から金属ブリケットを取り出すという方法が普通である。
また、ブリケットシートは、ブリケット本体の周囲、とりわけ両端にブリケットシートの連結部分の押し切りにより生じたバリ部が残されるように分断することが好ましい。こうすることにより、無駄をなくすことができる。
さらに、バリ部は、長さが1~5mmであることが利用性のうえからも好ましい。このような分断により全く無駄が生じることなく優れた成形性およびハンドリング性を発揮する金属ブリケットを得ることができる。
図1は、本発明の製造工程を示すフロー図である。以下、このフロー図に従い、本発明を更に詳述する。
