本発明はウオーキング炉の材料装入構造に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a material charging structure for a walking furnace.
ウオーキング式加熱炉あるいはウオーキング式熱処理炉
で、炉尻側から炉内に材料を装入する際に、炉の側面す
なわち前面壁近傍の側壁に開口部を設け、そこから材料
を縦方向に装入する方法が多く採用されている。In a walking heating furnace or walking heat treatment furnace, when charging material into the furnace from the bottom of the furnace, an opening is provided in the side wall of the furnace, that is, near the front wall, and the material is charged vertically from there. Many methods have been adopted.
この方法を示したものを第１゜図、第２図に示す。１は
ウオーキングハース式加熱炉の長手方向に延びた側壁２
は炉幅方向に延びた炉尻側壁、即ち前面壁である。３は
側壁１に開口部を設けた材料Ｍの炉尻側装入口である。This method is shown in Figs. 1 and 2. 1 is a side wall 2 extending in the longitudinal direction of a walking hearth type heating furnace.
is a side wall of the furnace tail extending in the width direction of the furnace, that is, a front wall. Reference numeral 3 denotes a furnace bottom side charging port for material M, which has an opening in the side wall 1.

わち鎖線で示すＭの位置まで押し込まれることになる。Material M is placed on a roller table 4 close to the charging port 3 outside the furnace.
Overwriting = Charging car 5 placed so that it can move forward and backward is charged into a horizontal charging hearth 6. Next, the charging hearth 6
The material M on top penetrates the front wall 3 and is pushed into the end of the fixed hearth 8, that is, the position M indicated by the chain line, by the charging device 7 that protrudes from outside the furnace into the furnace. .
固定炉床８の端部（二押し込まれた材料Ｍは可動炉床９

方向Ａすなわち抽出側へと搬送される。The end of the fixed hearth 8 (the second pushed material M is the movable hearth 9
In a transport cycle of descending, retreating, rising, and advancing, the material is sequentially transported in the direction of arrow A, that is, toward the extraction side.

ル４な経て、装入炉床６上へ押し出すので、装入材料の
方向性は定まらないことが多かった。However, since the charging material M is a slab-rolled steel billet or a steel billet extracted from a continuous casting machine, it is inevitable that the material will be bent during the cooling process or during cutting of the material. In addition, the push metal part at the tip of the charging car 5 is
Just by contacting the material, the material is pushed out through the table 4 of the straight rollers and onto the charging hearth 6, so the directionality of the material is often not determined.
このような曲がりのある材料が不安定な方向性やもって
装入されると、装入炉床の範囲を越え、炉内側へ押され

料先端を引っ掛け、装入が不可能となったり、既に炉内
に装入されている材料に衝突し、炉内材料間隔を狂わし
、材料の均一加熱が行なわれない原因を生じさせた。If such curved material is charged with an unstable orientation, it may exceed the range of the charging hearth and be pushed into the furnace. In this case, the movable hearth space 1 part I: the tip of the material may get caught, making it impossible to charge, or collide with the material already charged in the furnace, disrupting the material spacing in the furnace. This caused the material to not be heated uniformly.
また、炉内側へ入りすぎると、前面壁に設けた装入装置
の材料押し込みストロークでは、完全に押せず、やはり
適正な材料間隔が得られなくな−っだ。In addition, if the material entered too far inside the furnace, the material could not be pushed completely with the material pushing stroke of the charging device installed on the front wall, making it impossible to obtain an appropriate material spacing.
一方、装入材料が前面壁側へ押された場合には、前面壁
に衝突し、壁面を損傷させた。On the other hand, when the charged material was pushed toward the front wall, it collided with the front wall, damaging the wall surface.

供するものである。... [The present invention is directed to the material charging path, that is, the material charging hearth 6, from the end of the fixed hearth 8 toward the hearth butt wall, that is, the front wall side.
A taper roller having an inclination angle approximately equal to that of the material charging path is provided near the outside of the material charging port 3, and The object of the present invention is to provide a material charging hearth for a walking furnace that completely eliminates the above-mentioned troubles by disposing, for example, a guide plate having an uneven shape when viewed from a longitudinal section at a portion corresponding to the material height.
本発明に基づ〈実施例を第３図、第４図により説明する
。An embodiment based on the present invention will be explained with reference to FIGS. 3 and 4.
図中の番号１〜９は、第１図、第２図で指示する個所と
対応している。本発明では装入炉床６を固定炉床８の端
部から前面壁２に向け′て、固定炉床８レベルＬより、
直線状に低くなるように傾斜させている。Numbers 1 to 9 in the figures correspond to the locations indicated in FIGS. 1 and 2. In the present invention, the charging hearth 6 is directed from the end of the fixed hearth 8 toward the front wall 2, and from the level L of the fixed hearth 8,
It is sloped downward in a straight line.
従って装入口３から装入される材料は、自重の摩擦力に
よる分力により装入炉床６の傾斜方向すなわち前面壁２
側へと導かれることになる。Therefore, the material charged from the charging port 3 is moved in the direction of the inclination of the charging hearth 6, that is, the front wall 2, by the component force due to the frictional force of its own weight.
You will be led to the side.
また、材料装入口３の炉外近傍には、装入炉床６とほぼ
等しい傾斜角度をもつテーパローラ４を、装入炉床と同
一の傾斜方向に並列設置している。Further, near the outside of the furnace of the material charging port 3, taper rollers 4 having approximately the same inclination angle as the charging hearth 6 are installed in parallel in the same inclination direction as the charging hearth.

により固定している。FIG. 4 shows an embodiment in which a guide plate 10 is provided at a portion corresponding to the material height inside the front wall furnace. The guide plate 10 is made of heat-resistant steel or the like, and has an uneven shape when viewed from a longitudinal section so that it can withstand material impact from the lateral direction X, and has a large section modulus to increase mechanical strength. , a cross-sectional structure that is less likely to cause thermal distortion increases the effectiveness. Further, the guide plate 10 is fixed from outside the front wall furnace through a channel or the like by tightening bolts.

護されることになる。Since the present invention is configured as described above, the charging material is conveyed on the roller table along the slope of the tapered roller, and is regulated by the front wall side, which is the inclined direction in the furnace material charging path. Become. Furthermore, since the front wall is provided with an uneven guide plate, the side wall is protected even if the material is restricted to the front wall side.
したがって装入口から曲がりのある材料が、不安定な方
向性をもった状態で装入されても、装入炉床範囲を越え

トラブルが回避されることになる。Therefore, even if curved material is charged from the charging port with unstable directionality, various problems caused by exceeding the range of the charging hearth or colliding with the front wall can be avoided. That will happen.
