Description

Technical field:

[0001] The utility model relates to the technical field of steelmaking equipment, in particular to a hydraulic jacking device for removing refractory materials from a continuous casting tundish. Background technology:

[0002] When the continuous casting tundish reaches the end of its service life, the residual slag and refractory working lining in the offline tundish need to be removed and rebuilt, which is a time-consuming and labor-intensive work method. Utility model content:

[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and to provide a hydraulic jacking device for removing refractory materials from a continuous casting tundish. The device welds a hinged shaft connecting block at the bottom of the continuous casting tundish and uses a hydraulic cylinder to drive the jacking, thereby quickly removing the residual slag and refractory working lining in the continuous casting tundish.

[0004] In order to solve the problems existing in the background technology, the utility model adopts the following technical solution: it includes a continuous casting tundish bottom, a hinged shaft connecting block, a hydraulic station, a hydraulic cylinder, a quick-connecting bolt, a connecting support and a pin shaft. A hinged shaft connecting block is provided at the bottom of the continuous casting tundish bottom, the hinged shaft connecting block is connected to the hydraulic cylinder through a pin shaft, the hydraulic cylinder is connected to the connecting support through a quick-connecting bolt, and the hydraulic cylinder is connected to the hydraulic station.

[0005] The bottom of the continuous casting tundish is the bottom of the continuous casting tundish, and both ends of the continuous casting tundish are connected to the tundish tilting device through a quick-change connection device.

[0006] The beneficial effects of the utility model are:

[0007] 1) The entire device has no connectors with the tundish tilting device, thus avoiding the generation of additional external forces on the tundish tilting device during operation, which may cause deformation and bending.

[0008] 2) Simple structure and low maintenance cost. Description of the drawings:

[0009] Figure 1 It is a schematic structural diagram of the utility model. Specific implementation method:

[0010] Reference Figure 1The present invention specifically adopts the following implementation: it includes a continuous casting tundish bottom 1, a hinged shaft connection block 2, a hydraulic station 3, a hydraulic cylinder 4, a quick-connect bolt 5, a connecting support 6, and a pin 7. The bottom of the continuous casting tundish bottom 1 is provided with a hinged shaft connection block 2, which is connected to the hydraulic cylinder 4 via a pin 7. The hydraulic cylinder 4 is connected to the connecting support 6 via a quick-connect bolt. The hydraulic cylinder 5 is connected to the hydraulic station 3. The continuous casting tundish bottom 1 serves as the bottom of the continuous casting tundish 8. The two ends of the continuous casting tundish 8 are connected to the tundish tilting device 10 via quick-change connection devices 9.

[0011] When using this hydraulic jacking device for removing refractory materials from a continuous casting tundish, hydraulic station 3 provides power to hydraulic cylinder 4, which is placed below the tundish bottom 1 and connected to the hinged shaft connecting block 2 at the bottom of the tundish bottom 1. By welding the hinged shaft connecting block 2 to the bottom of the tundish bottom 1, hydraulic cylinder 4 is used to drive the jacking, enabling the rapid removal of residual slag and the refractory working lining within the continuous casting tundish.

[0012] In summary, the hydraulic jacking device for removing refractory materials from the continuous casting tundish has no connectors between the entire device and the tundish tilting device, thus avoiding additional external forces on the tundish tilting device during operation that may cause defects such as deformation and bending; the structure is simple and the maintenance cost is low.
