本発明は、ウオーキングビーム式加熱炉から被
加熱材（以下「材料」という）を何等トラブルな
く自動抽出する方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for automatically extracting a material to be heated (hereinafter referred to as "material") from a walking beam heating furnace without any trouble.
（従来の技術）

ローラ上に受け渡される。(Prior art) In the case of a walking beam heating furnace, the material W
The materials are sequentially transferred from the charging side to the extraction side while being delivered alternately between the fixed beam and the moving beam, and are heated during this process. Then, the material W that has been conveyed to the extraction end is delivered onto the extraction roller by the material extraction device in response to an extraction command.

料の抽出ずれは900−550＝350mm程度発生してい
ることがわかる。 By the way, when materials are charged into a heating furnace, they are arranged in parallel at a constant pitch, but the arrangement changes during transportation in the furnace, and the arrangement at the extraction reference position is, for example, as shown in Figure 10A. This may result in skewing, bending as shown in B and C of the same figure, or pecking of materials. This change is thought to be caused by the heat pattern of the heating furnace, the operating conditions of the furnace, the stiffness and feed error of the walking beam, the mechanical properties of the material, the furnace type, etc. Therefore, due to the above-mentioned change in the arrangement during transportation within the furnace, the extraction position of the material will shift from the extraction reference position. FIG. 11 shows the results of an investigation by the present inventors regarding the extraction position of the material. As is clear from the results of this investigation, it can be seen that the material extraction deviation occurs by approximately 900-550=350 mm.

ている。 Therefore, as disclosed in Japanese Utility Model Application Publication No. 62-97162, laser beam detectors are installed at two locations on the ceiling near the extraction reference position, and the difference in detection time of the extracted material by each detector is calculated. The amount of skew of the extracted material is calculated from this calculated value, and based on the calculated amount of skew, each material extraction device of the multiple material extraction devices arranged in the width direction of the furnace is driven, that is, the movement during forward and backward movement. The speed is controlled so that the skew of the extraction material is corrected and delivered onto the extraction roller.

置での抽出作業ができない。(Problem to be Solved by the Invention) However, as described above, the waiting state of the extraction material W at the extraction reference position is not limited to the oblique state, and the material W itself may be in a curved state. be. Therefore, in the conventional method,
If the extracted material is in a diagonal state without heating bending,
However, in a diagonal state that includes heating bending or in a heated bending state, extraction work using the material extraction device cannot be performed.
従つて、かかる材料配列の変化、特に、抽出材
料に加熱曲がりが発生して場合には、自動抽出が
不可能となる為、手動抽出によつて材料を抽出し
ていた。そのため、加熱炉の操業能率が低下する
ことになる。 Therefore, if such a change in material arrangement occurs, especially if the material to be extracted is bent by heating, automatic extraction becomes impossible, so the material has been extracted by manual extraction. As a result, the operating efficiency of the heating furnace decreases.

グビーム式加熱炉の材料抽出方法である。(Means for Solving the Problems) The present invention provides a method for extracting a material heated to a predetermined temperature using a plurality of extraction rollers arranged in parallel in the furnace width direction on the extraction side of a walking beam heating furnace. Two or more material extraction devices arranged in parallel between them can each be driven independently, and a position detection device for the extracted material is provided at a position corresponding to each material extraction device to detect the position of the extracted material in the longitudinal direction. This material extraction method for a walking beam heating furnace is characterized in that the material extraction method is carried out by independently controlling the position of each corresponding material extraction device based on each detected value.

運転で材料を確実に抽出できる。(Effects of the Invention) As explained above, the present invention provides a method for extracting a material heated to a predetermined temperature using a plurality of extraction rollers arranged in parallel in the width direction of the furnace on the extraction side of a walking beam heating furnace. to 2
More than one extractor arranged in parallel can be driven independently, and a position detection device for the extracted material is provided at a position corresponding to each extractor to detect the longitudinal position of the extracted material. Extraction is performed while controlling the position of each extractor independently based on the value. In particular, since the position of each extractor is controlled independently using individual position detectors, the material at the extraction material position is in a skewed state. Of course, even if the material itself is in a heated bent state or an oblique state that includes heated bending, the extractor can reliably extract the material automatically without correcting the arrangement of the material.
