Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the tail-seen steel tapping device comprises a walking beam 1, wherein the walking beam 1 is used for transferring steel billets from a heating furnace to a tapping cantilever roller 2, the tapping cantilever roller 2 comprises a plurality of rotating rollers, the walking beam 1 and the plurality of rotating rollers on the tapping cantilever roller 2 are arranged at intervals, and the installation height of the walking beam 1 is higher than that of the tapping cantilever roller 2.

A tapping roller table 9 is arranged on one side of the tapping cantilever roller 2, an HMD3-4ZC1 hot metal detector 10 is arranged on one side parallel to the tapping roller table 9, whether a billet exists at a corresponding position on the tapping roller table 9 or not can be detected through temperature change of the hot metal detector 10, a pinch roller 12 is arranged at the tail end of the tapping roller table 9, a roller 13 is arranged on the outer side of the pinch roller 12, the roller 13 is a working roller and used for rolling a billet material, the pinch roller 12 is used for stably sending the billet on the tapping roller table 9 into the roller 13, and according to the length of the billet, the hot metal detector 10 is placed at the position eight meters in front of the roller 13.

During installation, the installation height of the tapping roller table 9 is higher than that of the tapping cantilever roller 2 and the walking beam 1.

And meanwhile, a lifting assembly is arranged below the tapping cantilever roller 2 and is used for driving the tapping cantilever roller 2 to lift, and when the lifting assembly drives the tapping cantilever roller 2 to lift, the height of the tapping cantilever roller 2 can be consistent with that of a tapping roller way 9.

As the preferred scheme of this embodiment, lifting unit includes base 3, lift cylinder 4, lift swing arm 5, installation piece 6 and connecting rod 7, wherein base 3 and lift swing arm 5 all are equipped with two, bilateral symmetry places, lift swing arm 5 wholly is L shape, and the centre of L shape lift swing arm 5 rotates and connects on base 3, lift swing arm 5's one end is rotated and is connected on installation piece 6, the other end is connected with lift cylinder 4, and connecting rod 7's both ends are rotated respectively and are connected on controlling two lift swing arms 5.

A bearing beam is arranged below a plurality of rotating rollers of the tapping cantilever roller 2, wherein the upper end surface of the mounting block 6 is fixed on the bottom surface of the bearing beam of the tapping cantilever roller 2 by welding.

Still electric connection has PLC controller 11 in hot metal detector 10's top, has time-recorder 8 through screwed connection in the side of lift cylinder 4 simultaneously, and PLC controller 11 and time-recorder 8 and lift cylinder 4 electric connection, when PLC controller 11 control signal sent promptly, time-recorder 8 starts, begins the timing, and after appointed time, PLC controller 11 control lift cylinder 4 starts.

The working process and principle are as follows: the steel billet in the heating furnace is firstly transferred to the walking beam 1, when the hot metal detector 10 detects that the steel billet exists at the corresponding position on the furnace outlet roller way 9, the PLC controller 11 has no response, the steel billet continues to wait on the walking beam 1, and along with the rotation of the furnace outlet roller way 9, as shown in figure 1:

the billet moves to the right gradually, send the roll 13 through pinch roll 12 and roll in, when the end of billet, after hot metal detector 10 is crossed to the left end face promptly, hot metal detector 10 passes through the temperature variation, detect that the corresponding position on the roll table 9 of drawing off the furnace does not have the billet, hot metal detector 10 sends the signal this moment, PLC controller 11 receives after the point signal, start timer 8, according to the rolling efficiency of roll 13, set the time of timer 8 for 20 seconds, after 20 seconds, through PLC controller 11 control lift cylinder 4 extension, when lift cylinder 4 extends, drive L shape lift swing arm 5 around the tie point rotation on the base 3, as shown in FIG. 3:

under the effect of connecting rod 7, when controlling 5 anticlockwise rotations of two lift swing arms, can promote out of furnace cantilever roller 2 rebound through installation piece 6, when out of furnace cantilever roller 2 highly be higher than walking beam 1, the steel billet on the walking beam 1 can shift out of furnace cantilever roller 2 on, out of furnace cantilever roller 2's height and out of furnace roll table 9's highly uniform time, drive out of furnace cantilever roller 2 through the motor and rotate, the steel billet shifts on out of furnace roll table 9, then send the interior rolling of roll 13 through out of furnace roll table 9 and pinch roll 12.

Then the furnace is retracted through the lifting cylinder 4 to drive the discharging cantilever roller 2 to descend, and the operation is repeated.

Because the billet adopts flame cutting, and receive the sizing machine precision, influence such as crystallizer wearing and tearing, can not guarantee billet weight, the sizing is the same completely, consequently the rolling time of roll 13 also has the difference, in order to avoid piling up too much billet before roll 13, consequently survey the rolling progress of roll 13 through hot metal detector, after the billet afterbody passes through hot metal detector 10, just carry out the billet and shift after the rethread PLC controller 11 control lift cylinder 4 postpones 20 seconds, guarantee can not pile up too many billets before tapping roller 9 or roll 13, guarantee going on smoothly of rolling process.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
