〈産業上の利用分野〉
本発明は高炉に装入して用いる焼結法を製造する場合に
用いるバインダーに関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a binder used in the production of a sintering method that is charged into a blast furnace.
〈従来の技術〉
現在行われている焼結法は、約10m+m以下の鉄鉱石

焼結パレットに装入後表層部のコークスに点火し、下方
向へ空気を吸引し乍らコークスを燃焼させ、その燃焼熱
で粉鉱石を焼結させる方法である。<Prior art> The currently used sintering method involves mixing iron ore powder of approximately 10 m+m or less with coke and an appropriate amount of limestone powder.
In this method, after charging into a sintering pallet, the coke in the surface layer is ignited, the coke is combusted while sucking air downward, and the fine ore is sintered by the combustion heat.
この襟に、コークスの燃焼により焼結が進行する為に焼
結層への空気の供給度合を決定する焼結層の通気性の程
度は操業上の重要な要因となる。Since sintering progresses through the combustion of coke, the degree of permeability of the sintered layer, which determines the degree of air supply to the sintered layer, is an important operational factor.
この通気性を向上させる為に造粒条件の改善や造粒時間
の延長等種々の方策が講じられているが、用いるバイン
ダーも大きな要因である。従来からこの種の焼結に用い
られているバインダーは、生石灰や急結セメント成分で
ある。Various measures have been taken to improve this air permeability, such as improving granulation conditions and extending granulation time, but the binder used is also a major factor. Binders conventionally used in this type of sintering are quicklime and quick-setting cement components.
〈発明が解決しようとする問題点〉
上述した焼結用バインダーとして用いられている生石灰

用方法は少なく、はとんど埋立廃棄処分されている。The present inventor previously made an invention using steelmaking slag as an inexpensive binder for sintering, as published in Japanese Patent Application No. 84148/1983, and also made an invention using ferronickel slag and steelmaking slag, No. 143039 has already been filed, and although blast furnace water slag is used as an admixture for blast furnace cement, it has not been completely digested and effective utilization is desired. Furthermore, there are few effective ways to use the slag (water slag and slow cooling) generated during the manufacturing process of ferromanganese and silicomanganese, and most of the slag is disposed of in landfills.

セメントを用いる事もある。Means for Solving the Problems> The present invention uses inexpensive blast furnace slag, ferronickel slag, ferromanganese slag, and silicomanganese slag in place of quicklime and quick-setting cement that have been conventionally used as sintering binders. The main points are ferromanganese slag and/or silicomanganese slag, steelmaking slag that has been rapidly cooled from a molten state, blast furnace water slag, ferronickel slag, and Ca504.2
H201CaO+Ca(OH)2, Naoll, Nat
This is a method for producing a sintering binder consisting of a mixed powder with a stimulant consisting of at least one type of CO3, in which the steelmaking slag used in this case is mixed with silicate rocks or minerals or their weathered products while in a molten state. A modifying material consisting of at least one of the following is added and subjected to a melting reaction: karami, glass waste, caster waste sand 2 coal ash, waste bricks, red mud, volcanic ejecta, blast furnace slag, desiliconization slag, and iron oxide. It is sometimes used in the form of a quenched product, and cement is sometimes used instead of steelmaking slag.

By using ferromanganese slag, silicomanganese slag, ferronickel slag, steelmaking water slag, cement, and a small amount of stimulants, it can be used as a sintering binder that can replace expensive quicklime and quick-setting cement. In that case, the effect on the sintered product is equivalent to that of conventional expensive quicklime. It is also beneficial from the point of view of recycling blast furnace slag and steelmaking slag, which are byproducts of the steel industry, as well as ferromanganese slag and ferronickel slag, which are byproducts of ferroalloy manufacturers.
