。Sintered ore is made by mixing coke powder as a fuel in a predetermined ratio to a sintered raw material that is a mixture of main raw materials such as iron ore powder and Fe-containing dust, auxiliary raw materials for MgO sources such as serpentine, and slag-forming materials such as limestone powder. This mixed raw material is charged into the pallet of the sintering machine, and the coke powder is ignited in the ignition furnace, and then the coke powder is combusted by the air sucked through the wind box.
Manufactured by sintering main raw materials and auxiliary raw materials.

副原料としては、蛇紋岩のほかにカンラン岩、ニッケル
スラグ等が使用されている。The above-mentioned auxiliary raw material, serpentinite, is a Mg substance that increases the fluidity of blast furnace slag and improves the softening under load of sintered ore in the blast furnace.
It is added as an O source, and in addition to serpentine, peridotite, nickel slag, etc. are used as such auxiliary raw materials for the MgO source.
上述のように、蛇紋岩等のＭｇＯ源用副原料を配合した
焼結鉱は、高炉スラグの流動性を高め且つ高炉内におけ
る焼結鉱の荷重軟化性を改善する利点があるが、一方、
焼結鉱の高炉内における被還元性を劣化させる問題があ
る。As mentioned above, sintered ore mixed with auxiliary raw materials for MgO sources such as serpentine has the advantage of increasing the fluidity of blast furnace slag and improving the softening property of sintered ore under load in the blast furnace.
There is a problem in that the reducibility of sintered ore in the blast furnace deteriorates.
このような焼結鉱の被還元性の劣化は、高炉操業におけ
るエネルギー消費量の増大を招き好ましくない。Such deterioration in the reducibility of sintered ore is undesirable because it leads to an increase in energy consumption during blast furnace operation.
従って、この発明の目的は、高炉スラグの流動性全高め
且つ高炉内における荷重軟化性を改善する九めにＭ、０
源用副原料を配合しても、被還元性の優れ几焼結鉱を製
造する方法を提供することにある。Therefore, the object of the present invention is to completely increase the fluidity of blast furnace slag and improve the load softening property in the blast furnace.
The object of the present invention is to provide a method for producing sintered ore having excellent reducibility even when supplementary raw materials are mixed therein.
本発明者等は、上述した目的を達成すべく鋭意研究を重
ねた。ＭｙＯ源用副原料の配合によって焼結鉱の被還元
性が劣化する原因は次の通っである。The present inventors have conducted extensive research in order to achieve the above-mentioned objective. The reasons why the reducibility of sintered ore deteriorates due to the addition of the MyO source auxiliary raw material are as follows.
従来のＭ、０源用副原料は、第１表に示すような化学成
分組成および第２表に示すような粒度分布を有している
。Conventional auxiliary raw materials for M, 0 sources have chemical compositions as shown in Table 1 and particle size distributions as shown in Table 2.
従って、焼結時における副原料中のＭ２Ｏと主原料中の
Ｆ￥！２０３ との反応によって、多量のマグネタイト
（Ｆｅ５ｓｔ ）が生成し、このマグネタイトの定めに
焼結鉱の被還元性が劣化する。Therefore, M2O in the auxiliary raw material and F\ in the main raw material during sintering! Due to the reaction with 203, a large amount of magnetite (Fe5st) is produced, and this magnetite deteriorates the reducibility of the sintered ore.
そこで、焼結時においてＭ、ＯがＦ’ｅ２ｏ３と反応し
ないようにＭｈｏ源用副原料を粗粒化すれば、マグネタ

Main raw materials such as iron ore powder and Fe-containing dust are mixed with auxiliary raw materials for Mho sources such as serpentine and slag materials such as limestone powder, and a predetermined proportion of coke powder is added to the tomo-sintering raw materials and sintered. In the method for producing sintered ore, 5 of the Mto source auxiliary raw materials
It is particularly characterized by having a particle size of 0 wt.% or more, 1 wt.% or more, and 10 w or less.

合割合を低下させた場合よりも大きい。In this invention, the reason why the particle size of 50 Wt. The aim is to suppress the generation of magnetite by suppressing the reaction between MgO in the auxiliary raw material Φ and Fe20s in the main raw material during sintering. That is, by suppressing the generation of magnetite, the amount of FeO in the sintered ore is reduced, and as a result, the reduction ratio (RI) t- of the sintered ore can be significantly improved. This effect is greater than when the blending ratio of coke powder is lowered.
