Detailed Description
In order that the present invention may be more readily and clearly understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
Fig. 1 is a schematic structural diagram of a cooling device for dynamically adjusting the flatness of a slab according to this embodiment. The cooling device comprises an upper cooling assembly, a lower cooling assembly and a cooling water flow regulating assembly. The upper cooling assembly may deliver cooling water to the upper surface of the slab. The lower cooling assembly can convey cooling water to the lower surface of the slab. The cooling water flow regulating assembly can regulate the flow of cooling water in the upper cooling assembly and the lower cooling assembly, so that the temperature of the upper surface and the lower surface of the plate blank is closer to a target value, and the flatness of the plate blank is ensured.
Specifically, the upper cooling assembly comprises an upper cooling nozzle 1 and a cooling water delivery pipeline 3 communicated with the upper cooling nozzle 1. The lower cooling assembly comprises a lower cooling nozzle 2 and a cooling water delivery pipe 3 communicating with the lower cooling nozzle 2. The upper cooling nozzle 1 is located above the slab and faces the upper surface of the slab. The lower cooling nozzles 2 are located below the slab and face the lower surface of the slab. The cooling water conveying pipeline 3 can convey cooling water to the corresponding cooling nozzles, and the cooling nozzles spray the cooling water to the surface of the plate blank to cool the plate blank.
In the present embodiment, the upper cooling nozzles 1 and the lower cooling nozzles 2 are each provided with five. Five upper cooling nozzles 1 and five lower cooling nozzles 2 are all arranged along the horizontal direction in sequence at equal intervals, and the upper cooling nozzles 1 and the lower cooling nozzles 2 are symmetrically arranged along the horizontal direction, namely, any upper cooling nozzle 1 and the adjacent lower cooling nozzle 2 are positioned on the same vertical line. When the plate blank passes through the cooling device, the five upper cooling nozzles 1 and the five lower cooling nozzles 2 spray cooling water to the plate blank at the same time, and the upper surface and the lower surface of the plate blank are cooled simultaneously.
Preferably, the upper cooling nozzle 1 and the lower cooling nozzle 2 are both fan-shaped, the spraying range is wide, and the sprayed cooling water is more uniformly distributed on the surface of the slab.
The upper cooling assembly further comprises an atomizing gas delivery conduit 6 communicating with the upper cooling nozzle 1. Correspondingly, the lower cooling assembly also comprises an atomising gas delivery duct 6 communicating with the lower cooling nozzle 2. The atomizing gas delivery duct 6 can deliver atomizing air to the corresponding cooling nozzle. The atomizing air in the atomizing gas delivery pipe 6 and the cooling water in the cooling water delivery pipe 3 are mixed at the inlet end of the corresponding cooling nozzle and then sprayed out from the cooling nozzle. After the atomized air is mixed with the cooling water, the uniformity of the cooling water sprayed by the cooling nozzle can be further improved.
It will be appreciated that a cooling water flow rate regulating valve 4 for regulating the flow rate of cooling water in the pipe is installed in the cooling water delivery pipe 3. And a control valve 7 for controlling the on-off of the pipeline is arranged on the atomized air conveying pipeline. And the cooling water flow regulating valve 4 and the control valve 7 are electrically connected with the main control equipment. The operator can control the flow of the cooling water in the cooling water conveying pipeline 3 and the on-off of the atomized air conveying pipeline by controlling the cooling water flow regulating valve 4 and the control valve 7.
Preferably, a flow meter 5 is installed on the cooling water delivery pipe 3. The flow meter 5 is electrically connected with the main control equipment. The flow meter 5 can monitor the flow rate of the cooling water in the corresponding pipeline in real time and transmit the monitored data to the main control equipment.
The technical scheme can ensure that the cooling rate of the upper surface and the cooling rate of the lower surface of the plate blank are consistent, thereby ensuring the flatness of the plate blank and the quality of the plate blank.
In addition to the above embodiments, the present invention may have other embodiments; all technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the present invention.
