Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting rollers, in particular to a guide water jacket type continuous casting roller. Background Art

[0002] As the core component of the continuous casting machine, the continuous casting roller mainly serves as a solidification container, bending and straightening the casting, driving and conveying the solidified casting, etc. The quality, strength and service life of the continuous casting roller have a great influence on the operation rate of the continuous casting machine. During the production process, if the continuous casting roller has an accident, it may cause the entire production line to stop production.

[0003] The existing continuous casting roller has a single structure. Since the surface circumferential temperature distribution of the continuous casting roller is uneven in the working state, unevenly distributed thermal stress will be generated on the surface and inside of the continuous casting roller. The external cooling water cannot be evenly transported to the inside of the continuous casting roller, and the heat inside the continuous casting roller cannot be evenly absorbed. After long-term use, the continuous casting roller will be damaged, reducing the service life of the continuous casting roller. Utility Model Content

[0004] In order to solve the above problems, that is, to solve the problems raised by the above background technology, the utility model proposes a guide water jacket type continuous casting roller, comprising:

[0005] Axis core;

[0009] Cavity B is formed in the shaft core and is connected to cavity A at one end away from the water outlet;

[0010] A water inlet hole is formed in one end of the shaft core and communicated with the cavity B.

[0011] Preferably, a plurality of X-shaped reinforcement members are fixedly installed in the cavity B.

[0012] Preferably, a plurality of reinforcing columns are fixedly installed in the cavity A.

[0013] Preferably, a rotating water feeder and a rotating water outlet are provided at one end of the shaft core, the rotating water feeder is communicated with the water inlet, and the rotating water outlet is communicated with the water outlet.

[0019] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0020] The utility model provides a guide water jacket type continuous casting roller, comprising:

[0021] Axis core 1;

[0022] The roller 2 is arranged on the outer surface of the shaft core 1;

[0023] The roller 2 is fixedly mounted on the outer surface of the shaft core 1 and can be fixed relatively thereto;

[0024] Cavity A3, formed in roller 2;

[0025] The water outlet 4 is formed in one end of the shaft core 1 and communicates with the cavity A3;

[0026] The cavity B5 is formed in the shaft core 1 and is connected to the cavity A3 at one end away from the water outlet 4;

[0027] A water inlet hole 6 is formed in one end of the shaft core 1 and communicates with the cavity B5;

[0028] The external cooling liquid can enter the cavity B5 through the water inlet 6 to cool the shaft core and flow into the cavity A3 to cool the roller 2, and then flow out through the water outlet 4.

[0029] Specifically, a number of X-shaped reinforcement members 7 are fixedly installed in the cavity B5;

[0030] Several X-shaped reinforcement members 7 can support the inner wall of the cavity B5, play a reinforcing role, and prevent the cavity B5 from deforming.

[0031] Specifically, a number of reinforcing columns 8 are fixedly installed in the cavity A3;

[0032] A number of reinforcing columns 8 can support the inner wall of the cavity A3, play a reinforcing role, and prevent the cavity A3 from deforming.

[0033] Specifically, a rotating water feeder 9 and a rotating water outlet 10 are provided at one end of the shaft core 1, the rotating water feeder 9 is connected to the water inlet 6, and the rotating water outlet 10 is connected to the water outlet 4;

[0034] The rotary water feeder 9 is fixedly mounted on one end face of the shaft core 1, and can facilitate the staff to transport the external coolant from the rotary water feeder 9 to the water inlet 6. The rotary water outlet 10 is fixedly mounted on one end face of the shaft core 1, and can facilitate the water in the cavity A3 to flow out from the water outlet 4.

[0035] Specifically, cavity A3 and cavity B5 are both annular cavities, which can increase the contact area between the coolant and the roller 2 and the shaft core 1, thereby improving the cooling efficiency.

[0036] Specifically, a protective layer 11 is provided on the outer surface of the roller 2 , and the protective layer can protect the roller 2 , improve its wear resistance, and prevent the roller 2 from being damaged.
