Description

Technical Field

[0001] The utility model relates to the field of roller cores, in particular to a cast roller core. Background Art

[0002] As we all know, casting rollers are essential tools for casting and rolling machines. Most of the existing casting rollers are equipped with roller sleeves on their outer walls, and the steel is rolled by the roller sleeves. As the rolling time increases, the temperature of the roller sleeves and the roller core gradually rises. The surface temperature of the roller sleeves can be cooled by a variety of methods, such as water cooling and air cooling, but the temperature between the roller sleeves and the roller core cannot be cooled, resulting in a large temperature difference between the inside and outside, causing the roller sleeves to be damaged, etc., which greatly increases the cost of use while reducing work efficiency.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a casting roll core, which has the following beneficial effects:

[0014] For the roll core of the cast roll, low-temperature water flows into the cooling pipe through a conduit, and the water in the cooling pipe exchanges heat with the roll core body. After the heat exchange, the high-temperature water flows back into the water tank through another conduit, thereby providing a heat dissipation effect for the roll core body, avoiding excessive temperature difference between the roll core body and the roll sleeve, avoiding damage to the roll sleeve, reducing costs and improving work efficiency.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When the gear rotates, the driving wheel 11 can drive the roller core body 1 to rotate. At this time, the conduit 10 can be supported by a designated device. This structure can be used with a designated water cooling device. The water cooling device includes a water pump, a water tank and a refrigeration component. The refrigeration component can cool the water in the water tank. The low-temperature water flows into the cooling pipe 5 through the conduit 10. The water in the cooling pipe 5 exchanges heat with the roller core body 1. After the heat exchange, the high-temperature water flows back to the water tank through another conduit 10, thereby providing a heat dissipation effect for the roller core body 1, avoiding excessive temperature difference between the roller core body 1 and the roller sleeve, avoiding damage to the roller sleeve, reducing costs and improving work efficiency.

[0022] If the sealing at both ends of the cooling tube 5 is insufficient, leakage will occur. A sealing ring is provided inside the flow guide frame 9 and is penetrated by the cooling tube 5. The sealing ring is made of silicone. When the two ends of the cooling tube 5 are inserted into the fixing seat 7, the sealing ring will be squeezed. The sealing ring can ensure the sealing of the two ends of the cooling tube 5 and avoid leakage at the two ends of the cooling tube 5.

[0023] In this structure, side blocks 8 are symmetrically arranged on both sides of the liquid guide ring 6, and cavities 4 are symmetrically arranged on both sides of the annular groove 2. The side blocks 8 are fixed inside the cavity 4 by bolts 12.
