用されてきた。 Conventional heating furnaces with movable hearths that can extract the heated material from the side of the heating furnace have only one series of multiple table rollers installed in the extraction side furnace, and are transported to the extraction reference position. The material to be heated can be extracted one by one in the case of long items, or multiple pieces at the same time in the case of short items, from the fixed hearth to the roller table by the movement of the movable hearth itself, or by installing an extractor and extracting it from outside the furnace. A method has been adopted in which extraction is carried out from above the fixed hearth to the roller table by the forward movement, upward movement, backward movement, and downward movement of an extraction arm that protrudes into the furnace and is operated from above.

も大きく阻害されていた。 In any of the above methods, automatic extraction may become impossible if the material to be heated is transported to the extraction reference position in the furnace and becomes misaligned during the process of being heated and transported and becomes slanted. In order to align the slanted material to be heated, a manually operated correction rod (not shown) protruding from outside the furnace into the furnace is used,
The tip of the extractor arm of the conventional extractor is used to poke the diagonally shaped heated material to correct its alignment to a parallel state, which is a complicated manual operation that wastes a lot of time. Moreover, productivity was also greatly hindered.

That is, the material to be heated is heated in the heating furnace 4 according to a predetermined heating pattern and is conveyed by the walking beam 12 while being alternately delivered to and from the fixed beam 11. is extracted one by one by the command,
It is further transferred onto the in-furnace roller table 8 by the walking beam 12, and extracted up to the pinch roll 5 near the extraction port 7 by the rotation of the in-furnace roller table 8 itself. The anti-extraction port 6 is a material extraction port in case of mill trouble. In such a conventional method, the materials to be heated 1, 2, 3, etc., which are conveyed to the extraction reference line, are disarranged during the process of being heated and conveyed and become oblique, which often causes automatic extraction to become impossible.

被熱材料２′で示している。 Furthermore, as shown in Fig. 2, in a walking type heating furnace having multiple series and a plurality of in-furnace roller tables, the automatic extraction conditions for the heated material are even stricter than in the case explained in Fig. 1 above. The extractor 10 extracts the material to be heated. In other words, the materials to be heated 1, 2, 3 are placed in the heating furnace 4.
The conditions are the same as in the case of FIG. 1, in which the inside is heated in a predetermined heating pattern while being alternately delivered to and from the fixed beam 11 by the walking beam 12 and transported to the extraction reference position. Then, the material to be heated 1 at the extraction reference position is transferred by the extractor 10 to the in-furnace roller 8 of the short axis of the in-furnace roller table 8, 13, which has two lines, which is closer to the furnace wall, according to an extraction command. I will post it. This state is shown by heat target material 1'. Next, the material to be heated 2 at the extraction reference position is transferred by the extractor 10 to the in-furnace roller table 13 with the long axis located away from the furnace wall among the two series of in-furnace roller tables. This state is shown by the heated material 2'.

系列の同時抽出が可能である。 The materials to be heated 1' and 2' transferred to the two series of furnace roller tables 8 and 13 are sequentially pinch rolled while being guided from the extraction port 7 to the extraction port guide wheel 15 according to the necessity of the mill side. into the mill (not shown) while synchronizing the pullout speed or mill speed of 5. Even after being fed into the mill, the rear parts of each extracted material 1' and 2' still remain in the furnace, but after the remaining materials in the furnace are completely removed, preparations are made to receive the next material to be heated. , the above operations are repeated in sequence. The anti-extraction port 6 is a material extraction port in case of mill trouble and is normally closed. As mentioned above, the in-furnace roller table is illustrated as being composed of two types: the long-axis in-furnace roller table 13 (see FIG. 3) and the short-axis in-furnace roller table 8 (see FIG. 4). Therefore, in this case 2

（図示せず）。 The shaft 16 is usually hollow and double-pipe, and is often internally water-cooled.Therefore, the shaft 16 is provided with a rotary joint 19 for water supply and drainage at the outer end of the furnace. A refractory sealing material 22 is provided at the portion where the shaft 16 penetrates from outside the furnace into the inside of the furnace.
This is used to prevent gas from blowing out from inside the furnace and preventing outside air from entering the furnace from outside. Bearings 17 and 17' for supporting the shaft 16 are mounted on a movable frame 20, and the movable frame 20 is stably mounted on a fixed frame 21. The short shaft furnace roller table 8 is supported and rotated via a shaft 16' as shown in FIG. The shaft 16' is usually rotatably supported by two sets of bearings 17, 17', and is mounted in a stable state in exactly the same manner as the long shaft in-furnace roller table 13 described above. Although the pass line (PL) of the long-axis in-furnace roller table 13 and the short-axis in-furnace roller table 8 are illustrated as being the same, if the pass line needs to be changed due to the mill's request, Furthermore, the roller table 8,
This can be done by adding a lifting device to 13 (not shown).

装置２６を備えている。 The extraction machine 10 is raised and lowered by raising and lowering the raising and lowering rollers 23 which are driven by a raising and lowering cylinder 24 (sometimes electric, but a cylinder is shown as an example) through a lever, and the extractor 10 is moved back and forth. This is normally done by a pinion rack type forward and backward movement device 25. A portion of the extractor 10 that penetrates the inside and outside of the furnace is provided with a sealing device 26 to prevent gas from blowing out from inside the furnace to the outside of the furnace, and to prevent outside air from entering the inside of the furnace from outside the furnace.

する結果となつている。 The tip of the extraction arm of the extraction machine 10 is equipped with a material holder 14, so that it is possible to transfer the heated materials 1 and 2 located at the extraction reference position S to the in-furnace roller tables 8 and 13 each having two lines. I'm used to it. However, in a regular extraction cycle as shown in FIG. 6a, if the heated materials 1 and 2 conveyed to the extraction reference position S become oblique and are out of alignment, automatic extraction is often impossible. Therefore, a flat motion operation is performed to correct the alignment to a parallel state by poking the slanted heated material with the tip of the extraction arm, which not only complicates the work but also greatly impedes productivity. There is.

つ掛け等トラブルの完全解消が計れなかつた。 As a means to solve the above-mentioned drawbacks, it is possible to automate the means of correcting the alignment to a parallel state by poking the diagonal heated material with the tip of the extraction arm. After performing one cycle of ascending → moving forward (perform alignment correction work here) → slightly retreating → descending → advancing → ascending → retreating → descending (returning to the starting point) from the starting point shown, next is the starting point shown in Figure 6 c. A total of 1 cycle: forward from (to a position that does not interfere with the already extracted material) → rise → forward (perform alignment correction work here) → slight retreat → descent → advance → rise → retreat → descent → retreat (return to starting point) Two cycles must be performed. According to this process, as mentioned above, the extraction cycle is extremely complicated, and it is not only difficult to keep up with operations where the extraction cycle is extremely fast, such as in the case of small cross-section steel pieces (materials such as billets). The positioning accuracy of the tip of the extractor arm was very precise, and it was not possible to completely eliminate problems in actual work, such as dropping the heated material due to insufficient stroke of the tip of the extractor arm, or catching the succeeding heated material due to excessive stroke. .

炉抽出機である。 This invention is intended to eliminate the numerous drawbacks mentioned above, and its gist is that the material to be heated is extracted from the side of the heating furnace. Two or more rows of table rollers are arranged in parallel in the furnace length direction, and a stepped protrusion is formed at the tip of the extractor installed in front of the heating furnace with a low step facing inside the furnace. This is a material extraction device for a heating furnace that is arranged so that the skew of the material to be heated can be corrected and extracted. That is, a plurality of table rollers are arranged in multiple rows in the extraction side furnace, and a plurality of materials to be heated, which have been conveyed by a movable hearth, are sequentially placed on the extraction reference line in the heating furnace, starting from the leading material at the extraction end. Even if the objects are individually slanted, the alignment is corrected so that they are parallel to each other, and the roller tables of the above-mentioned multi-row roller table are sequentially moved from the roller table closest to the extraction side furnace wall to the roller table located further away from the furnace wall. This heating furnace extractor is characterized by having an extraction arm equipped with an L-shaped protrusion to enable extraction of heat materials in multiple lines.
