Description

Technical Field

[0001] The utility model relates to the technical field of steel metallurgy production, in particular to a cored wire welding cooler. Background Art

[0002] The cored wire machine is a crucial component of the cored wire production process. Its primary function is to crush various additives (deoxidizers, desulfurizers, modifiers, alloys, etc.) to be added to molten steel or iron into a specific particle size, then incorporate this into a composite material of any length using cold-rolled low-carbon steel strip. This adjusts the molten steel's composition, significantly improving various parameters such as inclusion morphology to meet production requirements.

[0003] The current cored wire machine produces cored wire by wrapping alloy powder around a strip of steel. The steel strip obtained after uncoiling is not a continuous steel strip. The steel strip needs to be welded end to end to meet the needs of the steel strip production line. Welding equipment is required for welding. When the welding equipment currently used welds the steel strip of the cored wire, the heat during the welding process will cause the material around the weld to heat up rapidly, which may cause welding deformation, stress concentration, and even make the material brittle, affecting the subsequent coiling and packaging and even the wire feeding process, affecting production or process requirements.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example: Figure 1-2 As shown, the utility model provides a cored wire welding cooler, which includes a hot water tank 1, a cold air tank 2, a cold water tank 3, a left hot water pipe 9, a cold water pipe 10, a right hot water pipe 11, a left cold air pipe 12, a right cold air pipe 13, a cored wire 14 and a cooling wall 18;

[0023] The connection between the cold water tank 3 and the cold water pipe 10 can cool the welding part of the cored wire 14. The cored wire 14 passes through the cooling wall 18. By setting the cooling wall 18, after the cored wire 14 passes through the cooling wall 18, the cooling wall 18 begins to play a straightening role and standardizes the forward direction of the cored wire 14. A reserved water outlet 19 is provided at the lower part of the cooling wall 18. By setting the reserved water outlet 19, after the cooling water flushes and cools the welding part of the cored wire 14 and the surrounding tissues, the remaining cooling water is guided to the reserved water outlet 19 at the lower part through the cooling wall 18, thereby draining out the excess cooling water.

[0024] The left hot water pipe 9 and the right hot water pipe 11 are connected to the hot water tank 1, the cold water pipe 10 is connected to the cold water tank 3, and the left cold air pipe 12 and the right cold air pipe 13 are connected to the cold air tank 2;

[0025] The bottom of the hot water tank 1, the air conditioning tank 2 and the cold water tank 3 are all provided with a one-way valve 8. By setting the one-way valve 8, when the hot water tank 1, the air conditioning tank 2 and the cold water tank 3 are refilled, the one-way valve 8 can make the cooling medium flow in one direction to prevent the cooling medium in the hot water tank 1, the air conditioning tank 2 and the cold water tank 3 from being insufficiently filled and the pressure from being insufficient, resulting in a low degree of subsequent cooling process. A cold water pipeline electric valve 6 is provided in the middle of the cold water pipeline 10. The cold water pipeline electric valve 6 controls the cold water to enter the cold water pipeline 10 according to the prescribed route. The one-way valve 8 controls the cooling water to flow in one direction, and the cold water A power switch 7 is provided on the water pipe electric valve 6. By setting the power switch 7, the power switch 7 can control the switch and flow rate of the cooling water to adjust the cooling speed and cooling intensity of the cored wire 14. When the cold water pipe electric valve 6 is opened, the cold water tank 3 releases cold water through the cold water pipe 10, which can quickly cool the welding part of the cored wire 14. The one-way valve in the cold water pipe 10 controls the one-way input flow of cold water to prevent backflow during the re-addition of water. A hot water pipe electric valve 4 is provided in the middle of the left hot water pipe 9 and the right hot water pipe 11. When the cored wire 14 passes through After the track enters the reserved water inlet 19, the hot water pipe electric valve 4 is opened, and the hot water in the hot water tank 1 flows along the right hot water pipe 11 to the surrounding of the welding body, cooling the surrounding tissue of the cored wire 14 welding body. The one-way valve in the right hot water pipe 11 controls the one-way flow of hot water. After the cored wire 14 is cooled, the hot water pipe electric valve 4 is closed, and the hot water tank 1 stops delivering hot water. It is opened again when the cored wire 14 enters, and the cycle repeats. The one-way valve in the left hot water pipe 9 controls the one-way input flow of hot water to prevent backflow during the re-addition of water. The left cooling pipe 12 A cold air duct electric valve 5 is provided in the middle of the right cold air duct 13. When the cored wire 14 enters the cooling wall 18 through the track, the cold air duct electric valve 5 is opened, and the cold air in the cold air tank 2 flows along the right cold air duct 13 to the surrounding tissue of the welding, cooling the surrounding tissue of the cored wire 14 welding body. After the cored wire 14 is cooled, the cold air duct electric valve 5 is closed, and the cold air tank 2 stops supplying cold air. It is opened again when the cored wire 14 enters, and the cycle is repeated. The one-way valve in the right cold air duct 13 controls the one-way flow of cold air to prevent backflow during the re-filling process.

[0026] One-way valves are provided inside the left hot water pipe 9, the right hot water pipe 11, the left cold air pipe 12 and the right cold air pipe 13. Hot water pipe temperature sensors 15 are provided inside the left hot water pipe 9 and the right hot water pipe 11. Cold air pipe temperature sensors 16 are provided inside the left cold air pipe 12 and the right cold air pipe 13. The cold air pipe temperature sensor 16 can monitor the cold air temperature. A cold water pipe temperature sensor 17 is provided inside the cold water pipe 10. The cold water pipe temperature sensor 17 can monitor the cold water temperature in the cold water pipe 10. By arranging the hot water pipe temperature sensor 15, the cold water pipe temperature sensor 16 and the cold water pipe temperature sensor 17, when the cored wire 14 is straightened by the cooling wall 18 and enters the interior of the external cycloid, the hot water pipe electric valve 4, the cold air pipe electric valve 5 and the cold water pipe The electric valve 6 is opened, and the hot water pipe temperature sensor 15, the cold air pipe temperature sensor 16 and the cold water pipe temperature sensor 17 start to work automatically. In order to prevent the cored wire 14 from being over-cooled due to too low cooling temperature or insufficient cooling due to too high temperature during the cooling process, the hot water pipe temperature sensor 15, the cold air pipe temperature sensor 16 and the cold water pipe temperature sensor 17 are preset with a cooling temperature before the cored wire 14 enters the cooling wall 18 for straightening. After the cored wire 14 enters the cooling wall 18, the hot water pipe temperature sensor 15, the cold air pipe temperature sensor 16 and the cold water pipe temperature sensor 17 control the opening and closing degree of the hot water pipe electric valve 4, the cold air pipe electric valve 5 and the cold water pipe electric valve 6 by sensing the temperature of the internal cooling medium, thereby controlling the cooling temperature and degree of the cored wire 14.
