The present invention relates to a coke oven charging coal level flattening apparatus, and more particularly, to pull the charging coals charged into the coke oven in the reverse direction to prevent the stacking of the coals at an excessive height in the lower portion of the particular charging opening. The planarization work is smoothly reduced by providing a structure that significantly reduces the weight of the flattening device for leveling the charging coal level of the coke oven, thereby preventing the tip from sagging due to the load. The present invention relates to a charging coal level planarizing device including a device for improving a call density and further, a gas flow inside the carbonization chamber, to prevent poor dry flow.

In general, in order to make iron from iron ore, a chemical reaction called reduction is necessary, and coke is used to reduce iron ore, which is a kind of iron oxide, and carbon monoxide generated by burning coke reacts well with iron oxide because it is an unstable molecule. This is because it is reducing.

Prior to the introduction of such iron ore or coal into the furnace, it cannot be put in the furnace as it was taken from the mine. Therefore, iron ore is baked in the furnace and requires a sintering process to make iron ore agglomerates of a certain size. There is a need for a coke oven process, which is baked in an oven to produce a burnt mass called coke.

As shown in FIG. 1, the coke oven 110 generally includes a plurality of charging holes 112A, 112B, 112C, and 112D in a plurality of locations with respect to the width direction of the coke oven 110. The charging coal supplied from the charging vehicle is dropped down through the charging holes 112A, 112B, 112C, and 112D to be filled to a certain level in the coke oven 110, and this charging Coke is made by carbonizing the coal.

 At this time, the upper level of the charging coal filled in the coke oven is a portion (A) located directly below the charging hole is a higher peak form than the other parts (B) that are not, in severe cases close the lower part of the charging port It's about to let go. In addition, when the level of the charging coal is non-uniform, a problem occurs that the gas generated in the coke oven 110 is not properly processed. Therefore, the leveling of the charging coal level is performed by a level flattening device provided separately. The work is performed.
