Description

Technical Field

[0001] This utility model relates to the field of water cooling equipment technology, and in particular to a water cooling device for casting rolls. Background Technology

[0002] After molten metal is injected between the casting rolls, it needs to undergo cooling and crystallization deformation until it becomes a metal strip with the desired cross-sectional shape. During operation, the outer surface of the roll sleeve is in contact with the hot molten metal, while the inside of the roll sleeve is flushed by powerful cooling water to quickly remove a large amount of heat, resulting in intense heat exchange. The casting rolls bear both the rolling pressure of the deformed metal and enormous heat exchange stress, thus placing special requirements on the roll sleeve material and the roll structure. The selected roll sleeve material must be able to withstand alternating heat loads, have sufficient heat transfer capacity, not chemically react with the molten metal, and possess sufficient strength and rigidity to ensure the smooth progress of the casting and rolling process.

[0003] Casting rolls require the use of a water cooling device during operation, but the existing water cooling devices are not effective at cooling high-temperature water, which affects product quality and needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a water-cooling device for casting rolls in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A water-cooling device for casting rolls includes a water tank, a water pump, a return water pipe, a casting mill body, and a water inlet pipe. The water pump is installed on one side of the water tank, the return water pipe is installed on the other side of the water tank, the casting mill body is installed above the water tank, and the water inlet pipe is located above the return water pipe. It also includes a heat dissipation mechanism for cooling high-temperature water, which is installed on the water inlet pipe.

[0007] The heat dissipation mechanism includes a fixed shell and a heat dissipation component. The heat dissipation component is installed inside the fixed shell. The heat dissipation component includes a heat dissipation pipe, a fixed pipe, and a connecting pipe. The fixed pipe is installed at both ends of the heat dissipation pipe, and the connecting pipe is installed on the fixed pipe.

[0011] Preferably, the axial flow fan is connected to the fixed box by bolts, and the number of the coolers is three.

[0012] Preferably, the gas supply pipe is welded to the fixed box, and the number of gas supply pipes is seven.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] By setting up a heat dissipation mechanism, when the casting and rolling begins, the water pump is started. The cooling water in the water tank enters the casting rolls in the main body of the casting and rolling mill under the action of the water pump. The cooling water in the casting rolls absorbs heat and its temperature rises. The high-temperature water enters the fixed pipe through the water inlet pipe. The high-temperature water in the fixed pipe flows into the heat dissipation pipe. The heat in the high-temperature water is discharged through the heat dissipation pipe. There are many heat dissipation pipes and they are curved. This can prolong the heat dissipation time of the high-temperature water and expand the heat dissipation area of ​​the high-temperature water, effectively improving the cooling effect of the high-temperature water.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a water cooling device for casting rolls includes a water tank 1, a water pump 2, a return water pipe 3, a casting and rolling mill body 4, and a water inlet pipe 5. The water pump 2 is installed on one side of the water tank 1, the return water pipe 3 is installed on the other side of the water tank 1, the casting and rolling mill body 4 is installed above the water tank 1, and the water inlet pipe 5 is located above the return water pipe 3. It also includes a heat dissipation mechanism 6 for cooling high-temperature water, which is installed on the water inlet pipe 5.

[0027] In this utility model, the heat dissipation mechanism 6 includes a fixed shell 601, a heat dissipation pipe 602, a fixed pipe 603, and a connecting pipe 604. The heat dissipation pipe 602 is disposed inside the fixed shell 601, the fixed pipe 603 is installed at both ends of the heat dissipation pipe 602, and the connecting pipe 604 is installed on the fixed pipe 603. The heat dissipation pipe 602 is made of copper, and the fixed pipe 603 is welded to the heat dissipation pipe 602. When casting and rolling begins, the water pump 2 is started, and the cooling water in the water tank 1 enters the casting roll in the main body 4 of the casting and rolling mill under the action of the water pump 2. The cooling water in the casting roll absorbs heat and its temperature rises. The high-temperature water enters the fixed pipe 603 through the water inlet pipe 5, and the high-temperature water in the fixed pipe 603 flows into the heat dissipation pipe 602. The heat in the high-temperature water is discharged through the heat dissipation pipe 602. There are many heat dissipation pipes 602, and they are curved, which can prolong the heat dissipation time of the high-temperature water and expand the heat dissipation area of ​​the high-temperature water, effectively improving the cooling effect of the high-temperature water.

[0028] In this invention, a cooling mechanism 7 is installed on the heat dissipation mechanism 6. The cooling mechanism 7 includes a fixed box 701, an axial flow fan 702, a cooling plate 703, a cooler 704, an air supply pipe 705, and a nozzle 706.

The axial flow fan 702 is connected to the fixed box 701 by bolts. There are three coolers 704. The air supply pipe 705 is connected to the fixed box 701. 01 Welding, the number of gas supply pipes 705 is seven; as the high-temperature water continues to dissipate heat, the temperature inside the fixed shell 601 gradually rises. The axial flow fan 702 and the cooler 704 are started. The outside gas enters the fixed shell 701 under the action of the axial flow fan 702. The cooler 704 cools the gas inside the fixed shell 701. The low-temperature gas inside the fixed shell 701 enters the gas supply pipe 705. The low-temperature gas in the gas supply pipe 705 is sprayed out through the nozzle 706. The low-temperature gas sprayed out by the nozzle 706 can reduce the temperature of the fixed shell 601. In this way, the heat dissipation effect of the high-temperature water is not affected, and the cooling effect of the high-temperature water is effectively improved.

[0029] In the above structure: when casting and rolling begins, water pump 2 is started. Cooling water in water tank 1 enters the casting roll in the main body 4 of the casting and rolling mill under the action of water pump 2. The cooling water in the casting roll absorbs heat and its temperature rises. The high-temperature water enters the fixed pipe 603 through the water inlet pipe 5. The high-temperature water in the fixed pipe 603 flows into the heat dissipation pipe 602. The heat in the high-temperature water is discharged through the heat dissipation pipe 602. As the high-temperature water continues to dissipate heat, the temperature inside the fixed shell 601 gradually rises. Axial flow fan 702 and cooler 704 are started. External gas enters the fixed box 701 under the action of axial flow fan 702. Cooler 704 cools the gas inside the fixed box 701. The low-temperature gas in the fixed box 701 enters the gas delivery pipe 705. The low-temperature gas in the gas delivery pipe 705 is sprayed out through nozzle 706. The low-temperature gas sprayed out by nozzle 706 can reduce the temperature of the fixed shell 601. After sufficient heat dissipation, the high-temperature water returns to the water tank 1 through the return water pipe 3.
