があつた。 Conventionally, the sag attached to these steel pieces was either passed on to the next process and used as is, or when it was necessary to remove it for marking, etc., the sag was removed manually with a crowbar, etc. Ta. This sag may cover the end face of the steel piece and become an obstacle to marking, or it may disappear as scale or remain on the steel piece when heated in a heating furnace. This may cause embossments and scratches, or it may remain attached to the edges and enter the product section, reducing the yield of the product. Sagging can be prevented by automatic marking or direct rolling of steel billets to save energy and labor.
This has become an obstacle in the continuous processing of steel billets, such as direct charging into a heating furnace, and it has been necessary to mechanically remove the sag in order to improve product quality and yield.

常ガス切断により鋼片を所定寸法にするため、凹
凸段差等の発生がさけられない）、段差Δxは必ず
生じるといえる。 By arranging the grindstone at an angle, the grindstone and the end of the steel piece can easily come into contact with each other. The reason for this will be explained next. As shown in Figure 6a, the side of the grindstone is attached to the steel piece 1.
If the grindstone is moved parallel to the side surface of the steel piece as shown by the arrow, it will collide with the end face of the steel piece if there is a step Δx. However, there is an uneven step on the end face (normally, the steel piece is cut to a predetermined size by gas cutting, so the occurrence of uneven steps, etc. is unavoidable), and it can be said that the step Δx will always occur.
しかしながら、第６図ｂに示すように砥石を傾
斜させることにより、砥石の研削面がガイドとし
て利用できることになる。 However, by tilting the grindstone as shown in FIG. 6b, the grinding surface of the grindstone can be used as a guide.
従つて凹凸面と干渉する状態となつていても、
砥石が研削面で鋼片端面の段差に倣つて乗りうつ

5 is a pin that swingably supports the support arm 13 on the support arm 12, 16 is a pin that swingably supports the grindstone shaft arm 14 on the support arm 13, 17 is an electric motor that rotates the grindstone 3, and 18 is a support with one end. 12 is swingably attached to the lower part of the support arm 13, and the other end is swingably attached to the support arm 13. One end of 19 is swingably attached to the middle of the column 12, and the other end is a grindstone shaft arm. A telescoping device is swingably attached to the support arm 1 when the telescoping device 18 expands and contracts.
3, the center of the whetstone 3 moves up and down from 0 1 to 0 2 to 0 3 , and when the telescoping device 19 expands and contracts, the whetstone shaft arm 14
The center of the grindstone 3 moves back and forth from 0 1 to 0 2 to 0 3 due to the oscillation. When the billet transfer cart 10 loaded with the billet 1 stops at a predetermined position, a device for detecting the position of the billet 1, which will be described later, determines the positions of the grindstone 3 and the billet 1, and the grindstone is rotated by the electric machine 17. 3 is pressed against the steel piece 1 by the expansion/contraction device 19, and the sag removing device cart 8 is run to grind the steel piece 1.

It is attached to 0. Detection arm 25 and steel piece 1
The rod 30 of the telescoping device 24 is pulled out by the swinging movement caused by the contact with the rod 30, and the contact between the limit switch 28 and the striker 29 provided in the outer cylinder 31 surrounding the rod 30 is released. the result,
A top surface detection signal of the steel piece 1 is output. In addition, 32
The limit switch shown by is for detecting whether the detection arm 25 is in the retracted position.In order to retract the detection arm 25 from the steel piece 1, when the rod 30 is further extended from the state shown in FIG. 30), the striker 29 then comes into contact with the limit switch 32, and at this stage it is known that the retraction of the detection arm 25 has been completed. At this time, the dimensions of each structure are determined so that the grindstone 3 is located exactly at the corner of the top surface of the end of the steel piece 1. Note that, of course, wear of the grindstone 3 is also taken into consideration in determining this dimension.

and the position of the grindstone 3 by operating the expansion and contraction devices 18 and 19, and the limit switch 2 provided on the expansion and contraction device 24.
8 and the detection point on the upper surface of the steel piece 1, which is determined from the arrangement position of the striker 29, are arranged so that they match at the corner position of the upper surface of the end of the steel piece 1. As shown in FIG. 4, the grinding wheel 3 is set to come into contact with the end surface of the steel piece 1 at the upper surface detection point of the steel piece 1 by the limit switch 28 and the striker 29. Therefore, this position becomes the grinding line on the upper end surface of the steel piece 1, and this grindstone position is detected by the upper surface detection device and output to the control device 11.

This detection device is attached to a cover 9 surrounding the sag removing device shown in FIG. 1, and is arranged using a bracket 23 provided on the cover 9 in FIG. 1 as a base. That is, as shown in FIG. 5, the bracket 33 is fixed to the cover 9, and the telescopic device 3 is attached to this.
4 is swingably attached to one end by a pin 35, and the other end is swingably attached to one end of a detection arm 36, and a part of the detection arm 36 is swingably attached to a bracket 33. It is being
The detection arm 36 is equipped with a touch roll 37 at its tip that contacts the side surface of the steel piece 1. When the sagging device trolley 8 is run with the telescopic device 34 protruding, when the touch roll 37 comes into contact with the side surface of the steel piece 1, the force tries to retract the telescopic device 34 via the detection arm 36. If a limit switch or the like is used to detect that the extension device 34 is out of the protrusion limit, the side surface of the steel billet 1 can be detected. Here, 38 indicates a limit switch, and 39 indicates a striker. 40
indicates the rod of the telescoping device 34, and this rod 40
A striker 39 is attached to the tip. Therefore, as the sagging device cart 8 moves to the right in FIG. 5, the detection arm 36 is pushed by the steel piece 1, and the end of the detection arm 36 swings to push the rod 40 toward the telescoping device 34. The contact between the striker 39 attached to the rod 40 and the limit switch 38 is released, and the end face of the steel piece 1 is detected at this point. After detecting this end face, the detection arm 36 is retracted from the steel piece 1 by activating the telescopic device 34 and retracting the rod 40. The completion of retraction is detected by the striker 39 and the limit switch 4.
1 contact can be detected.
なお側面の検出位置に丁度砥石３の中心がくる
ように各構造寸法が決められている。 The dimensions of each structure are determined so that the center of the grindstone 3 is exactly at the detection position on the side surface.

ように構成している。 Therefore, the telescopic devices 18 and 19 (FIG. 1) are operated so that the center of the grindstone 3 is located at the side surface detection position, and the side surface detection position is detected and output to the control device 11. After detecting both the top surface and the side surface of the steel piece, the detection arms 25, 36 are moved to the telescopic device 24,
34 in the retracting direction, and after retracting the detection arms 25 and 36 from the surface of the steel piece, grinding is performed. Further, during detection, the weights of the detection arms 25, 36 and the touch rolls 27, 37 are increased so that it is not necessary to apply large pressure to the expansion and contraction devices 24, 34.

法を走行して研削を行う。 Grinding is performed as follows. First, in order to remove the sagging 2 after cutting the steel piece 1 shown in FIG. The sagging device cart 8 is moved in the width direction of the steel piece 1 with the position of the end face of the steel piece determined by the arm 36 as a reference point. During this time, the grindstone 3 is being driven to rotate, and the telescoping device 18,
19 has been finely adjusted. Here, the traveling distance of the sagging device trolley 8 is controlled by separately given steel piece information, that is, the width dimension and the thickness dimension, and grinding is performed by traveling the above width dimension from the end face position determined by the detection arm 36. .

Grinding is performed until the thickness of the steel slab in the piece information is reached.
なお、マーキング位置等の情報を合わせて与え
