An embodiment of the present invention provides a method for detecting the length of a slab, which is used to detect the length of the slab 2 before the slab 2 enters the heating furnace, including steps:

S1 setting the detection position, setting the first detection position and the second detection position, and the distance between the first detection position and the second detection position is a preset distance;

That is, two positions are selected first, and the two positions are respectively set as the first detection position and the second detection position, and the distance between the first detection position and the second detection position is a preset distance. Detectors are arranged at the first detection position and the second detection position, so as to detect the slab 2 . The value of the preset distance may be equal to the standard length of the slab 2 .

S2 Move the slab 2, move the slab 2 so that it passes through the first detection position and the second detection position in sequence, and the length direction of the slab 2 is parallel to the line between the first detection position and the second detection position during the movement ;

After the first detection position and the second detection position are selected, the slab 2 is moved, and the length direction of the slab 2 is kept parallel to the line between the first detection position and the second detection position during the movement. Before moving, the slab 2 is completely located on the side of the first detection position away from the second detection position; during the movement, the first end of the slab 2 first passes through the first detection device, and the first end passes through the first detection position in turn and the second detection position.

S3 detection, judging whether the first detection position and the second detection position detect the slab 2 at the same time, if yes, the length of the slab 2 exceeds the standard length.

In the process of moving the slab 2, if the first end of the slab 2 has passed the second detection position and the second end has not passed the first detection position, the first end of the slab 2 is located far away from the second detection position. One side of the first detection position and the second end are located on the side of the first detection position away from the second detection position, so at this time the slab 2 can be detected at both the first detection position and the second detection position, that is, at this time If the first detection position and the second detection position detect the slab 2 at the same time, it can be determined that the length of the slab 2 exceeds the standard length.

Applying the slab overlength detection method provided by the present invention, it is possible to judge whether the length of the slab 2 exceeds the standard length by identifying whether the first detection position and the second detection position detect the slab 2 at the same time, and then realize that the slab 2 enters The length of the slab 2 is detected before the heating furnace, thereby avoiding the situation that the slab 2 is too long to be loaded when the slab 2 is close to the furnace, which saves time and greatly improves the work efficiency.

Further, after the detection step, it also includes: if the length of the slab 2 exceeds the standard length, prohibiting the slab 2 from entering the heating furnace. In this way, the continuous operation of the roller table can be blocked by increasing the interlocking signal between the equipments, and the signal can be used to notify the staff to take the slab off the line in time to realize the purpose of prohibiting the slab 2 from entering the heating furnace.

Specifically, the preset distance may be 11000mm. Of course, the preset distance can also be set according to actual conditions, which is not limited here.

The present invention also provides a slab overlength detection device, which includes a first detector 1 , a second detector 3 and a conveying member. Wherein, the first detector 1 and the second detector 3 can detect the slab 2, the distance between the first detector 1 and the second detector 3 is a preset distance, the first detector 1 can be located at the first detection position, the second detector 3 may be located at the second detection position. The conveying member can drive the slab 2 to move, and the first detector 1 and the second detector 3 are arranged along the conveying direction of the conveying member. When the conveying part drives the slab 2 to move, the length direction of the slab 2 remains parallel to the conveying direction of the conveying part, that is, the length direction of the slab 2 is also parallel to the connecting line between the first detection position and the second detection position.

Using the slab overlength detection device, the slab 2 is moved by using a conveying member. Before moving, the slab 2 is completely located on the side of the first detector 1 away from the second detector 3 . During the moving process, the first end of the slab 2 first passes the first detector 1 , and the first end passes the first detector 1 and the second detector 3 in sequence. In the process of moving the slab 2, if the first end of the slab 2 has passed the second detector 3 and the second end has not passed the first detector 1, the first end of the slab 2 is located at the second detector 3 on the side away from the first detector 1 and the second end is located on the side of the first detector 1 away from the second detector 3, so both the first detector 1 and the second detector 3 can detect The slab 2, that is, the first detector 1 and the second detector 3 detect the slab 2 at the same time, then it can be determined that the length of the slab 2 exceeds the standard length. In this way, the length of the slab 2 can be detected before the slab 2 enters the heating furnace, thereby avoiding the situation that the slab 2 is too long to be loaded when the slab 2 is approaching the furnace, which saves time And greatly improved work efficiency.

Specifically, for the convenience of detection, both the first detector 1 and the second detector 3 can be located above the conveying member, so that the first detector 1 and the second detector 3 can detect the upper surface of the slab 2 . Certainly, the first detector 1 and the second detector 3 may also be respectively located on both sides of the conveying member, which is not limited here.

Wherein, the first detector 1 and the second detector 3 may both be cold metal detectors, or of course other types of detectors, as long as the slab 2 can be detected.

Specifically, the conveying member may be a roller table 4, and of course may also be a conveyor belt, which is not limited herein.

Likewise, the preset distance between the first detector 1 and the second detector 3 may be 11000mm. Of course, the preset distance can also be set according to actual conditions, which is not limited here.

The slab overlength detection device may also include a controller connected in communication with the first detector 1 and the second detector 3, if the first detector 1 and the second detector 3 detect the slab 2 at the same time, the control The device prohibits the slab 2 from entering the heating furnace. In this way, the control by the controller saves more labor and saves labor costs.

Further, it also includes an alarm communicated with the controller. When the first detector 1 and the second detector 3 detect the slab 2 at the same time, the controller controls the alarm to give an alarm. Like this, once there is super long slab 2, then alarm just can notify staff.
