[0034] In the following description, a large number of details are discussed in order to provide a more thorough explanation of embodiments of the application, however, it will be apparent to those skilled in the art that embodiments of the application can be practiced without these specific details, and in other instances, well known structures and devices are shown in block diagram form, rather than in detail in order to avoid obscuring embodiments of the application.

[0035] In an exemplary embodiment, the present application exemplarily provides a tundish control method, please refer to Figure 1 , Figure 1 is a flow chart of a tundish control method according to an exemplary embodiment of the present application, the method at least includes steps S110 to S150, which are described in detail as follows:

[0036] Step S110, when the billet is detected by the laser detection in the furnace, the walking beam is lowered to the front middle position of the heating furnace, and the tundish action command is sent;

[0037] Step S120, the furnace door of the heating furnace is raised to the half-open position;

[0038] Step S130, the tundish is extended into the heating furnace, and at the same time, the furnace door of the heating furnace is raised to the fully open position;

[0039] Step S140, after the tundish is extended to the position, it is raised to the upper position, and the billet is placed on the roller;

[0040] Step S150, the tundish is lowered to leave the billet, and the roller is started to send the billet.

[0041] The steps S110 to S150 are described in detail as follows:

[0042] In step S110, when the laser detection in the furnace detects the billet, the walking beam is lowered to the front-middle position of the heating furnace, and a tundish action instruction is sent.

[0043] It should be noted that the walking beam needs to perform the stepping cycle actions of ascending, advancing, descending, and retreating, and sequentially passes through the upper position, the upper-front position, the front-middle position, the lower-front position, the lower position, and the rear-middle position of the heating furnace. In the prior art, the tundish needs to wait for the walking beam to complete the last stepping cycle action, and the billet reaches the tundish position, so that the tundish action instruction can be sent. The tundish waits for a long time for the walking beam to complete the stepping cycle action.

[0044] Specifically, the distance between the walking beam and the bottom of the heating furnace is 1000m. When the walking beam is lowered to the front-middle position of the heating furnace, the distance between the walking beam and the bottom of the heating furnace is less than 500m. When the walking beam is lowered to the front-middle position of the heating furnace, the tundish action instruction is sent, so that the tundish can start to perform the tundish action during the time when the walking beam is lowered from the front-middle position to the rear-middle position, thereby saving the waiting time and improving the tundish efficiency.

[0045] In step S120, the heating furnace door is raised to the half-open position. During the descending process of the walking beam, the distance between the walking beam and the bottom of the heating furnace is measured by the displacement sensor. When the distance between the walking beam and the bottom of the heating furnace is less than 500m, it is determined that the walking beam is lowered to the front-middle position of the heating furnace, and the tundish action instruction is sent to the heating furnace. The heating furnace door is opened, and the heating furnace door is raised to the half-open position, so that the tundish can extend into the heating furnace. This can effectively reduce the heat overflow of the heating furnace, reduce the energy consumption of the heating furnace, and save the production cost.

[0046] In step S130, the tundish extends into the heating furnace, and at the same time, the heating furnace door is raised to the fully open position. After the heating furnace door is opened and raised to the half-open position, the tundish extends into the heating furnace. At the same time, the heating furnace door continues to rise to the fully open position. During the process of the tundish extending into the heating furnace, the detection element detects the extension position of the tundish to ensure that the tundish is extended to the designated position.

[0047] It should be noted that in the prior art, the tundish needs to extend into the heating furnace and reach the designated position first, and then the heating furnace door is raised to the fully open position. During the tundish extension process, the tundish needs to wait for a long time for the tundish to extend into the heating furnace and for the door to rise to the fully open position. In the present application, the tundish extension and the door rising are performed synchronously, which shortens the tundish waiting time and improves the tundish efficiency.

[0048] In step S140, after the tundish is extended to the position, it is raised to the upper position, the billet is placed on the roller way, and the tundish starts to descend to reset when the billet is placed on the roller way.

[0049] In step S150, the roller way is started to send the billet at the same time when the tundish descends to leave the billet. In the prior art, after the tundish places the billet on the roller way, it needs to wait for the tundish to reset to the lowest position completely before the roller way is started to send the billet. The waiting time for the tundish to reset is long. In the present application, the sending signal is sent to start the roller way to send the billet when the tundish leaves the billet and does not contact the billet, so that the billet is sent to the next process.

[0050] It can be seen that the technical scheme provided by the embodiment reduces the waiting time of the tundish in the process of tapping. When the laser inspection in the furnace detects the billet, the walking beam is lowered to the front middle position of the heating furnace, the tapping action instruction is sent, the furnace door of the heating furnace is raised to the half-open position, the tundish is extended into the heating furnace, and at the same time, the furnace door of the heating furnace is raised to the fully open position. After the tundish is extended to the position, it is raised to the upper position, the billet is placed on the roller way, and finally the tundish is lowered to leave the billet, and the roller way is started to send the billet, so that the billet is sent to the next process. The waiting time of the tundish in the process of tapping is reduced, the tapping efficiency is improved, the production efficiency is ensured, the opening time of the furnace door of the discharge furnace is shortened, the heat overflow of the heating furnace is reduced, and the energy consumption and production cost of the heating furnace are reduced.

[0057] The billet feeding module 205 is configured to, after the tundish is lowered to leave the billet, start the roller way to feed the billet.

[0058] The steel tapping control device provided in the application is characterized in that, when the laser detection device detects the billet in the furnace, the tundish is first lowered to a front middle position of the heating furnace, a steel tapping action instruction is sent, the heating furnace receives the instruction, the furnace door is raised to a half-open position, the tundish is extended into the heating furnace, at the same time, the furnace door of the heating furnace is raised to a fully-open position, after the tundish is extended into position, the tundish is raised to an upper position, and the billet is placed on the roller way, finally, the tundish is lowered to leave the billet, and the roller way is started to feed the billet, thereby reducing the waiting time of the tundish in the steel tapping process, improving the steel tapping efficiency, guaranteeing the production efficiency, shortening the opening time of the furnace door of the discharge furnace, reducing the heat overflow of the heating furnace, and reducing the energy consumption and production cost of the heating furnace.
