DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for detecting the temperature of a sintered raw material layer on a pallet in a moving grate type sintering machine (hereinafter referred to as DL sintering machine).

似粒塊とした焼結原料をDL焼結機で焼結鉱としたもの
が主要原料として使用されている。
As is well known, in modern iron metallurgy, powders such as iron ore lime and coke are kneaded with an appropriate moisture content, and the sintered raw materials are made into coagulated granules and sintered using a DL sintering machine. The condensed ore is used as the main raw material.

前述のDL焼結機における鉄鉱石の焼結手段においては
、高温でも充分な潰裂強度を持ち、粉化しにくく、高い
通気性が保てる高品質の焼結鉱を得るため、焼成が基準
通り適確に進行しているかどうかを常に監視し、焼成制
御を適切に実施せねばならない。
In the method of sintering iron ore in the aforementioned DL sintering machine, sintering must be performed in accordance with standards in order to obtain high-quality sintered ore that has sufficient crushing strength even at high temperatures, is difficult to powder, and maintains high air permeability. It is necessary to constantly monitor whether the firing is progressing properly and to appropriately control firing.

例を上げるとDL焼結機ではパレットの移動速度が早す
ぎると焼成が不充分となる。
For example, in a DL sintering machine, if the pallet movement speed is too fast, sintering will be insufficient.

つまりベッド下層部まで充分な焼結反応が進行しないた
め歩留りが低下し得られた製品は落下強度の低いものと
なる。
In other words, since the sintering reaction does not proceed sufficiently to the lower layer of the bed, the yield decreases and the resulting product has low drop strength.

逆にパレットの移動速度が遅過がると焼結反応は充分で
あるが酸化が進みすぎて還元粉化指数が悪化する。
On the other hand, if the moving speed of the pallet is too slow, the sintering reaction will be sufficient, but oxidation will proceed too much and the reduction powdering index will deteriorate.

つまり生産性は著しく低下してしまう。In other words, productivity will drop significantly.

前述のように適切な焼成を行なうための一条件としての
パレットの移動速度のみをとっても、それぞれ異なった
原料配合の状態においてベッドの通気性が変化するため
、それに応じてパレットの移動速度の最適値も変化する
As mentioned above, even if we consider only the pallet moving speed as one condition for proper firing, the air permeability of the bed will change depending on the state of the different raw material compositions, so the optimal value of the pallet moving speed should be determined accordingly. also changes.

即ち通常の操業では原料配合、含水率、原料充填度等が
絶えず変動するため、それに応じてパレットの移動速度
を変更する必要がある。
That is, in normal operations, the raw material composition, moisture content, degree of filling of raw materials, etc. constantly change, so it is necessary to change the moving speed of the pallet accordingly.

In other words, it is required to maintain the firing rate at a value determined from past technical experience, but since there is no suitable index for determining the firing rate, conventionally the sinter cake fracture surface in the ore discharge area was Methods such as making judgments based on observation results, such as the shape, thickness, and brightness of the combustion zone, and operating so that the exhaust gas temperature distribution in the latter half of the strand is constant have been adopted.
