The present invention relates to a marking device for marking the specifications for the post-work process of the cast on a cast, such as a billet (BILLET) produced through the continuous casting process of the steel mill, more specifically, the casting of the cast through the marking device Convenient marking centering and leveling can be automatically and smoothly adjusted, so that the marking part of the cast steel is always constantly marked at the center of the face of the cast steel, thereby preventing line troubles in the post-process of the cast steel due to poor marking. It relates to a slab marking centering and leveling device of a slab marking facility to improve the line productivity of the product.

In general, molten steel that has undergone blast furnace operation is fed into a continuous casting machine to produce slabs such as slabs or rectangular billets with a cross section. Through the cutting process, the marking work is performed to indicate the specifications of each billet. In the post-working process of the produced cast steel, the marking work is performed as the marking equipment, and the marking equipment is shown in FIGS. 1 and 2. Doing.

That is, as shown in Figure 1, since the billet playing line is usually composed of about 6-8 lines, the billet 100 cast in the player is 6-8 lines (driven by the chain 110 driving method ( The feed is stopped along the guide rolls 122 of the 120 and stops by the stopper 140 installed in multiple rows at the marking points of the marking facility 130 disposed forward of the transfer lines 120. The operation stop of the transfer line 120 is performed by the limit switch 150 installed on the frame of the line 120 by the billet 100 to be transferred and quenched.

Of course, when the quench operation of the limit switch 150 is set in advance so that the line is stopped after a certain period of time, the cast steel to be transported so that the front portion is in close contact with the stopper 140.

On the other hand, the marking facility 130 is shown in detail in Figures 1 and 2, the transfer along the transfer line 120 is in contact with the stopper 140, the transfer is stopped, the installation frame 132 in front of the line The marking nozzle 136 on the lower side of the marking machine 134 moving along its length is to perform the marking operation on the front surface of the billet 100.

At this time, the marking machine 134 is a drive wheel 138 driven by the motor 138a installed on the upper side moves along the rail 132a of the frame 132, at this time billet transfer in the longitudinal direction of the frame 132 A multi-position position adjustment sensor 139a is installed in the same straight line as the line 120, and the sensor 139a is operated by a sensor detection bar 139b installed on the marking machine 134 side.

That is, when the marking machine 134 moves along the rail 132a of the installation frame 132 by driving the motor and coincides with the sensing bar 139b on the machine side and the sensor 139a installed in multiple rows on the frame 132. , The motor 138a of the machine 132 is stopped and the marking operation is performed on the front surface of the billet 100 whose position is matched as the nozzle 136 of the marking machine 134, and after a predetermined time, The motor is driven by the motor again to move along the rail 132a of the frame 132 to complete the following billet marking operations sequentially.

Of course, although not shown in the figure, it is also possible to adjust the marking position of the nozzle 136 of the marking machine 134 by using a sensor bar 139a as a limit switch, and by installing a pinch bar to hold it.

However, in such a conventional marking facility, a banding phenomenon occurs in which the tip portion sags downward due to trabble on the line during the transfer of the billet 100, or the centering of the billet is precisely adjusted on the transfer line 120. If it is conveyed to the left and right side rather than the right side, the centering and level state between the nozzle 136 of the marking machine 134 and the marking surface 100a of the billet 100 often becomes poor. There was no separate device to compensate for such centering and level failures.

That is, as shown in FIGS. 3A to 3C, the marking M is biased left or right or right on the marking surface 100a of the billet 100, or when the level is poor, the bias is upward.

Therefore, if the centering and level of the cast before the marking operation through the nozzle 136 of the marking machine marking machine 134, such as billet, it will be desirable to be able to always perform a constant marking operation as shown in Figure 3d.

The present invention has been made in order to improve the various problems as described above, the object of the present invention is to smoothly adjust the marking centering and level state of the cast during the marking of the cast through the marking device, the marking portion of the cast Marking centering and leveling of cast iron marking equipment to prevent line defects in the post-process of the cast due to poor marking and to improve product line productivity by marking at the center of cast iron face at all times.
