The electric furnace oxidation slag is provided as a granular material or a crushed material.
〔電気炉酸化スラグ粒化法〕
上記電気炉酸化スラグを粒化して粒状物を製造するには、該電気炉酸化スラグの溶融物を高速回転する羽根付きドラムに注入し、該溶融物を該羽根付きドラムによって破砕粒状化し、粒状化した該溶融物を水ミスト雰囲気中で急冷処理する方法が採られる。該羽根付きドラムは複数個配置して複数段の破砕粒状化を行なってもよい。
このようにして得られる電気炉酸化スラグの粒状物は、再酸化が促進されるので、Ｆe2Ｏ3 系の鉱物を多く含み、かつ急冷により、極微細な粒状物になるため、電磁波加熱性が非常に良好なものとなる。また通常５mm以下の粒径を有し、粒径２．５mm以下のものは略球状であり、比重は３．３〜４．１の範囲にあり、表面にはひび割れ等の欠陥はなく、微細な凹凸を有しまた中空構造のものからなるかまたは中空構造のものを含んでいる。
[Electric furnace oxidation slag granulation method]
In order to granulate the electric furnace oxidation slag, a granular material is produced by injecting a melt of the electric furnace oxidation slag into a bladed drum rotating at high speed, and crushing and granulating the melt with the bladed drum. A method of quenching the melted melt in a water mist atmosphere is employed. A plurality of bladed drums may be arranged to perform a plurality of stages of crushing and granulating.
Since the granular material of the electric furnace oxidation slag obtained in this way promotes re-oxidation, it contains a large amount of Fe 2 O 3 mineral and becomes extremely fine granular material by rapid cooling. Will be very good. Also, the particles having a particle size of 5 mm or less are usually spherical, and the specific gravity is in the range of 3.3 to 4.1, and there are no defects such as cracks on the surface. And have a hollow structure or a hollow structure.
〔電気炉酸化スラグ破砕法〕
上記電気炉酸化スラグ破砕物を製造するには、上記電気炉酸化スラグを溶融状態で耐熱容器中に所定の厚みに流し出し、上から水をかけることによって急冷改質処理が施される。この場合、耐熱容器中のスラグ溶融物の厚さが小さすぎると、水をかける前に自然冷却（徐冷）によって硬化し易くなり、所望の硬度が得られなくなるおそれがあり、また厚さが大きくなり過ぎると、水をかけた場合に水が急激に水蒸気となり、水蒸気爆発の危険がある。望ましいスラグ溶融物の厚さは８０mm〜１２０mmである。
[Electric furnace oxidation slag crushing method]
In order to manufacture the electric furnace oxidized slag crushed material, the electric furnace oxidized slag is poured into a heat-resistant container in a molten state to a predetermined thickness, and subjected to rapid cooling reforming by pouring water from above. In this case, if the thickness of the slag melt in the heat-resistant container is too small, it tends to harden by natural cooling (slow cooling) before applying water, and the desired hardness may not be obtained. If it becomes too large, when water is applied, the water suddenly becomes water vapor and there is a danger of water vapor explosion. The preferred slag melt thickness is 80 mm to 120 mm.
水をかける場合には耐熱容器中のスラグ溶融物のスラグ溶融物の表面に水が溜まらないようにすることが望ましく、水をかける量が多過ぎてスラグ溶融物の表面に水が溜まって水の蒸発潜熱による急冷効果が期待出来なくなる。
上記水をかける量は、スラグ溶融物１トン当たり毎秒２００〜４００リットル程度が望ましい。
上記急冷によってスラグ溶融物は急速に硬化するが、この際自己破砕によって容器中のスラグ溶融物の厚さ程度の径を有するスラグ原塊が得られる。
When water is applied, it is desirable to prevent water from accumulating on the surface of the slag melt in the heat-resistant container. Too much water is applied and water accumulates on the surface of the slag melt. The rapid cooling effect due to the latent heat of vaporization cannot be expected.
The amount of water applied is preferably about 200 to 400 liters per second per ton of slag melt.
The slag melt is rapidly cured by the rapid cooling, and at this time, a slag ingot having a diameter of about the thickness of the slag melt in the container is obtained by self-crushing.
該スラグ原塊は粗砕機で粗砕され、更に細砕機で細砕される。上記粉砕によって、スラグ塊はスラグ成分のマトリクスと鉱物相との境界で破断し、表面に微細な凹凸が形成される。所望なれば上記破砕物は粗篩機等によって粗分級され、更に細砕機等によって細分級して５〜２５mm望ましくは５〜２０mmの粗骨材、粒径５〜１３mm望ましくは５〜１０mmの粗骨材、および５mm以下の細骨材に分ける。 The slag bulk is crushed by a pulverizer and further pulverized by a pulverizer. By the pulverization, the slag lump is broken at the boundary between the slag component matrix and the mineral phase, and fine irregularities are formed on the surface. If desired, the crushed material is coarsely classified by a coarse sieving machine, etc., and further subdivided by a fine pulverizer or the like to give a coarse aggregate of 5 to 25 mm, preferably 5 to 20 mm, and a coarse particle of 5 to 13 mm, preferably 5 to 10 mm Divide into aggregates and fine aggregates of 5mm or less.
上記粗砕および細砕はスラグ原塊が水で濡れたまゝで行ってもよいし、またスラグ原塊を乾燥して粗砕以後の工程を行ってもよいし、あるいはスラグ原塊を粗砕した後に乾燥して細砕以後の工程を行ってもよい。また上記分級工程において、篩を通過しない残分は破砕工程に戻されることが望ましい。
このようにして得られる破砕物は徐冷スラグに較べ、再酸化が促進されるので、Ｆe2Ｏ3 系の鉱物を多く含み、かつ急冷により、微細な粒状物になるため、電磁波加熱性が非常に良好なものとなり、その比重は水砕品と同様３．３〜４．１の範囲にある。
The above crushing and pulverization may be carried out while the slag block is wet with water, or the slag block may be dried and subjected to the steps after crushing, or the slag block may be crushed. Then, it may be dried to carry out the steps after grinding. Moreover, in the said classification process, it is desirable to return the residue which does not pass a sieve to a crushing process.
Since the crushed material obtained in this way promotes reoxidation as compared with slow-cooled slag, it contains a lot of Fe 2 O 3 minerals and becomes a fine granular material by rapid cooling. It becomes very good, and its specific gravity is in the range of 3.3 to 4.1 like the granulated product.
〔改質電気炉酸化スラグ〕
更に本発明の電気炉酸化スラグには電磁波加熱性を向上させるための添加物を添加する。
上記電磁波加熱性を向上させるための添加物としては、Ｆe ，Ｂa ，Ｃo ，Ｎi ，Ｃr ，Ｃu ，Ｍn ，Ｓr ，Ｚn 等の金属あるいはこれら金属を含む合金あるいはこれらの金属の酸化物、水酸化物、塩化物、硫酸塩等の加熱により酸化物を与える化合物である。望ましい添加物としては鉄スクラップ、スケール、ＢａＯ屑、硫酸バリウムを含む重晶石等がある。
上記添加物は前記粒化法あるいは破砕法において、電気炉酸化スラグ溶融物に添加されるかあるいは電気炉酸化スラグに混合されて共に溶融される。上記溶融は通常電気溶解炉で行われるが、この時溶融物に空気または酸素を吹込み強制酸化処理を施す。上記強制酸化処理は特にＦe Ｏ比率が高い破砕法によるスラグに対して有効であり、上記強制酸化処理によってＦe2Ｏ3 比率を高めて電磁波加熱性を向上せしめることが出来る。
該改質電気炉酸化スラグも粒状物または破砕物として提供される。

In the granulation method or crushing method, the additive is added to the electric furnace oxidation slag melt or mixed with the electric furnace oxidation slag and melted together. The melting is usually carried out in an electric melting furnace. At this time, air or oxygen is blown into the melt and subjected to forced oxidation treatment. The forced oxidation treatment is effective against slug especially by Fe O ratio is high fracturing, by the forced oxidation treatment Fe 2 O 3 ratio of the can of improving an electromagnetic wave heating resistance enhances.
The reformed electric furnace oxidation slag is also provided as a granular or crushed material.

In the present invention, when a synthetic resin emulsion or rubber latex is used as the binder, the viscosity of the electric furnace oxidation slag granule or mixture of the crushed material and the binder, or the electric furnace when the binder is a hydraulic inorganic powder, is used. A thickener may be used to adjust the viscosity when kneading with water a powder composition mainly composed of a mixture of oxidized slag granules or crushed material, or a mixture obtained by mixing a water reducing agent in the mixture. .
