In the steel making process, steel products are passed through a heating furnace to a hot rolling step.

The material is conveyed through the roller table, placed on the front side of the inlet side of the heating furnace, and then the pusher conveys the material loaded on the roller table to the entrance end.

The material transferred to the loading end is charged into the loading door of the heating furnace by the operation of a walking beam and is gradually moved by the sequential operation of the working beam to eventually exit the heating furnace through the extracting door.

In the case of the working beam, after the work beam is placed at the home position, when the work is loaded, the working beam is turned up, and then the forward beam (FWD), the working beam down (down) It comes.

Conventionally, after a long lifting, that is, a pusher puts a material on a long mouth, and after returning to a home position, that is, a long lifting position, the operation of the walking beam is started, There was a process delay during the return to position.

The heating-channel working beam automatic control system according to the present invention can make various changes and may have various embodiments, and specific embodiments will be illustrated in the drawings and described in detail in the description. It should be understood, however, that the invention is not intended to be limited to the particular embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

1 is an embodiment in which a heating-beam working beam automatic control system according to the present invention is applied. 2 is a block diagram showing each configuration according to an embodiment of the present invention.

The heating furnace automatic control system 100 according to the present invention, as shown in FIGS. 1 and 2, includes a sensing unit 110; And a working beam adjusting unit 120.

First, the sensing unit 110 is a component for sensing the position of the pusher 3, as shown in FIG.

As shown in FIG. 1, the sensing unit 110 may be disposed at the long-side end 22 to sense the state of the working beam 2, which will be described later.

The sensing unit 110 senses position information of the pusher 3, which may be a laser pointing sensor or other optical sensor.

The position information of the pusher 3 sensed by the sensing unit 110 is utilized as reference information based on the function of the working beam adjuster 120.

2, the working beam adjusting unit 120 may directly or indirectly network with the sensing unit 110 to receive information about the position of the pusher 3.

The working beam adjusting unit 120 basically controls the operation of the working beam 2 of the heating furnace and the operation control of the working beam 2 is controlled by the position of the pusher 3 recognized by the sensing unit 110 .

More specifically, after the pusher 3 puts the work 1 on the long-end 22 of the work 1, the working beam adjuster 120 immediately starts the operation of the working beam 2 at the time of starting the retreat , So that there is no delay in the charging of the material (1).

That is, the working beam adjusting unit 120 can raise and lower the working beam immediately after the work 1 is placed on the groove arrangement of the working beam 2.

As shown in FIG. 1, the sensor unit 110 may include a first sensor 111.
