[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0019] Example

[0020] See also Figure 1 , Figure 3 and Figure 4As shown, a continuous casting sector comprises a continuous forging sector 1 and a protective cover 4. Top plates 2 are arranged on the tops of both sides of the continuous forging sector 1. Oil cylinders 3 are symmetrically arranged on both sides of the continuous forging sector 1. The oil cylinders 3 penetrate the top plates 2. Protective covers 4 are fixed on the upper surface of the top plates 2. The structure of the protective cover 4 is U-shaped and open outward, so that one side of the oil cylinder 3 is open to facilitate the heat dissipation of the oil cylinder 3 itself and isolate the heat transfer between the sector. The protective cover 4 is placed on the outside of the oil cylinder 3. Ear plates are symmetrically arranged on the outside of the bottom of the protective cover 4. Bolts 6 are symmetrically penetrated on the surface of the ear plates. The bolts 6 are screwed on the surface of the top plates 2. Check washers 7 are sleeved on the surface of the bolts 6. The check washers 7 are placed above the ear plates to prevent the bolts 6 from loosening due to vibration during the operation of the continuous forging sector 1.

[0021] Among them, the ear plates are connecting plates 5 fixed on both sides of the bottom of the protective cover 4 to ensure stability after installation and prevent it from moving. The protective cover 4 includes inner and outer steel plates 401 and a central quartz rubber plate 402. The quartz rubber plate 402 is used to increase the thermal insulation capacity.

[0022] Example

[0023] Please refer to Figure 1 and Figure 2 As shown, a lip 8 is provided on the outer side of the bottom of the protective cover 4. The lip 8 extending outward can improve the stability of the installation of the protective cover 4. The ear plate is an adjustment plate 9 that slides on the lip 8. The adjustment plate 9 slides to control the position between the adjustment plate 9 and the protective cover 4. Then, when the position of the threaded hole on the surface of the top plate 2 is fixed, the distance between the protective cover 4 and the cylinder 3 is adjusted to improve the practicality during use. A pressing plate 10 is provided on one side of the adjusting plate 9. The pressing plate 10 is placed above the lip 8. An anti-slip rubber pad 11 is glued to the lower surface of the pressing plate 10. The lower surface of the anti-slip rubber pad 11 contacts the upper surface of the lip 8. The adjustment plate 9 can be controlled to be pressed down by screwing the bolt 6, and then the lip 8 is pressed down by the pressing plate 10 to achieve the stability of the installation of the protective cover 4. At the same time, the anti-slip rubber pad 11 can increase the connection friction while ensuring that the lip 8 is prevented from being deformed due to excessive tightening of the bolt 6.

[0024] Working principle: The protective cover 4 is fixed to the upper surface of the top plate 2 by bolts 6, and the oil cylinder 3 is effectively wrapped to isolate the oil cylinder 3 from the internal equipment. The quartz rubber plate 402 inside the protective cover 4 can prevent the heat inside the continuous forging sector 1 from being transferred to the top plate 2, thereby ensuring the stability of the top plate 2 and improving its service life. According to the usage, a protective cover 4 with a fixed connecting plate 5 or a protective cover 4 with a movable adjustment plate 9 is selected to facilitate docking with the threaded holes on the surface of the top plate 2.

[0025] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
