Description

Technical Field

[0001] This utility model relates to the field of heating furnace technology, specifically to a conveyor slide for a copper ingot heating furnace. Background Technology

[0002] In the processing and production of copper tubes and rods, copper ingots need to be heated to a certain temperature before undergoing a series of processes such as forging and rolling. Electromagnetic induction heating furnaces are commonly used metal heating equipment in industrial production. Heating furnaces used for heating copper ingots are usually horizontally placed tubular structures. Copper ingots need to be conveyed into the heating furnace by a pushing device, and after heating, they are output by the pushing device.

[0003] The heating furnace used for heating copper ingots usually has a sleeve inside to support the copper ingots. In the existing technology, the copper ingots are generally pushed into the sleeve by a pushing device. This method causes the copper ingots to come into frictional contact with the inner wall of the sleeve during the pushing process, which can easily cause wear and tear on the sleeve during long-term use. Since the manufacturing cost of the sleeves is generally high, this method of conveying the sleeves will lead to an increase in maintenance costs.

[0004] Existing technologies also employ a method of using a slide rail within the heating furnace to allow copper ingots to slide into the furnace body under the action of a pusher. For example, Chinese patent document CN204080042U discloses a billet slide rail for a pusher-type heating furnace. This slide rail includes two parallel bottom water beams and multiple sliders fixed to each bottom water beam and evenly arranged along the axial direction of the bottom water beams. Each slider has multiple heat insulation holes. This slide rail can significantly reduce the energy loss of the billet, eliminate or reduce the black marks on the water beams of the heated billet, and thus improve the heating quality of the billet.

[0005] The aforementioned billet slide rails are exposed to high-temperature environments for extended periods during use, and are subjected to mechanical friction and impact from the sliding of billets. This makes them prone to fatigue damage and cracks due to thermal fatigue, which in turn increases maintenance costs. Furthermore, these billet slide rails are generally suitable for large fuel-fired heating furnaces and cannot be installed in small electromagnetic induction heating furnaces, resulting in poor applicability.

[0006] Therefore, a conveyor slide for a copper ingot heating furnace is needed that can avoid sleeve wear, reduce the maintenance cost of the heating furnace, and also reduce the probability of fatigue damage to the slide. Utility Model Content

[0007] This utility model provides a conveyor slide for a copper ingot heating furnace, which can not only avoid sleeve wear and reduce the maintenance cost of the heating furnace, but also reduce the probability of fatigue damage to the slide.

[0008] To solve the above problems, the present invention provides a conveyor slide for a copper ingot heating furnace, which adopts the following technical solution:

[0009] A conveying chute for a copper ingot heating furnace includes a cooling pipe. The cooling pipe is U-shaped and meanders around the bottom of a sleeve. The cooling pipe includes two straight sections arranged in parallel along the axial direction of the sleeve and a bend connecting the two straight sections. The two straight sections are used to slide and support the copper ingot. The ends of the two straight sections away from the bend have an inlet and an outlet, respectively, to input coolant into the cooling pipe.

[0010] This utility model discloses a copper ingot heating furnace. By installing a U-shaped cooling pipe inside the casing, the copper ingot can slide along the two straight sections of the cooling pipe under the action of the pushing device, avoiding the wear of the casing caused by long-term friction between the copper ingot and the casing, thereby reducing the maintenance cost of the heating furnace. By introducing coolant into the cooling pipe, the temperature of the cooling pipe in the heating furnace can be reduced, preventing the cooling pipe from overheating and fatigue due to excessive temperature, and improving the service life of the conveyor slide. At the same time, the cooling pipe has a simple structure, low manufacturing cost, and its size can be adjusted according to the volume of the heating furnace, making it highly adaptable.

[0011] Furthermore, the conveying chute also includes multiple connecting plates located between the two straight sections. The connecting plates are fixedly connected to the two straight sections. The connecting plates are arc-shaped plates, and the arc surface of the connecting plates fits against the inner wall of the sleeve.

[0012] Its beneficial effects are as follows: by setting multiple connecting plates between the two straight sections of the cooling pipe, the rigidity of the two straight sections of the cooling pipe can be enhanced, preventing the cooling pipe from deforming during use, ensuring the load-bearing strength of the cooling pipe, and extending the service life of the cooling pipe.

[0013] Furthermore, the connecting plate is fixed to the inner wall of the sleeve by welding.

[0014] Furthermore, the cooling pipe is characterized in that it has a diameter of 12 mm and a wall thickness of 2 mm.

[0015] Furthermore, the cooling pipe is characterized in that it is made of 310S stainless steel.

[0016] Its beneficial effects are as follows: 310S stainless steel has good high temperature resistance. By using 310S stainless steel as the manufacturing material of the cooling pipe, the high temperature resistance of the cooling pipe can be enhanced, the probability of fatigue damage to the conveyor slide can be reduced, and the service life of the conveyor slide can be extended.

[0017] Furthermore, the inlet and outlet are located outside the casing and at a height lower than the lower end of the casing to avoid affecting the copper ingot transportation.

[0018] Furthermore, the coolant is water.

[0019] Furthermore, the distance between the bend and the end of the sleeve is less than 80 mm.

[0020] The beneficial effects of the conveyor slide of the copper ingot heating furnace provided by this utility model are:

[0021] 1. This utility model discloses a copper ingot heating furnace. By setting a U-shaped cooling pipe inside the sleeve, the copper ingot can slide along the two straight parts of the cooling pipe under the action of the pushing device, avoiding the wear of the sleeve caused by long-term friction between the copper ingot and the sleeve, thereby reducing the maintenance cost of the heating furnace. By introducing coolant into the cooling pipe, the temperature of the cooling pipe in the heating furnace can be reduced, preventing the cooling pipe from overheating and fatigue due to excessive temperature, and improving the service life of the conveying slide. At the same time, the cooling pipe has a simple structure, low manufacturing cost, and its size can be adjusted according to the volume of the heating furnace, making it highly adaptable.

[0022] 2. By setting multiple connecting plates between the two straight sections of the cooling pipe, the rigidity of the two straight sections of the cooling pipe can be enhanced, preventing the cooling pipe from deforming during use, ensuring the load-bearing strength of the cooling pipe, and extending the service life of the cooling pipe.

[0023] 3. 310S stainless steel has good high temperature resistance. Using 310S stainless steel as the manufacturing material of cooling pipes can enhance the high temperature resistance of cooling pipes, reduce the probability of fatigue damage to the conveyor slide, and extend the service life of the conveyor slide.

[0031] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0032] Embodiment 1 of the conveyor slide of the copper ingot heating furnace provided by this utility model:

[0033] like Figures 1 to 5 As shown, a conveying chute for a copper ingot heating furnace includes a cooling pipe 2, a connecting plate 3, and a connector 4. The cooling pipe 2 is U-shaped and meanders within a sleeve 1 to slide and support the copper ingot, preventing frictional contact between the ingot and the sleeve 1. The connecting plate 3 is fixedly connected to both the cooling pipe 2 and the sleeve 1 to enhance the rigidity of the cooling pipe 2. The connector 4 is installed at both ends of the cooling pipe 2 for connecting to a coolant supply device.

[0034] The cooling pipe 2 is a round pipe with a diameter of 12 mm and a wall thickness of 2 mm. It is made of 310S stainless steel. 310S stainless steel has good high temperature resistance. By using 310S stainless steel as the manufacturing material of the cooling pipe 2, the high temperature resistance of the cooling pipe 2 can be enhanced, the probability of fatigue damage to the conveyor slide can be reduced, and the service life of the conveyor slide can be extended.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the cooling pipe 2 includes a bend 22 and two straight sections 21. The two straight sections 21 are arranged parallel to each other along the axial direction of the sleeve 1, and the distance between the two straight sections 21 matches the size of the copper ingot to support the copper ingot to slide along the axial direction of the sleeve 1 on the upper side of the two straight sections 21. The bend 22 is used to connect the two straight sections 21. The distance between the bend 22 and the end of the sleeve 1 away from the connector 4 is less than 80 mm to prevent the copper ingot from tilting downward when it is conveyed to the end of the sleeve 1, thus ensuring the stable conveying of the copper ingot at the end of the sleeve 1.

[0036] The connecting plate 3 is an arc-shaped plate with a downward arc. The radius of the lower side of the connecting plate 3 is the same as the inner diameter of the sleeve 1, so that the lower side of the connecting plate 3 fits against the inner side of the sleeve 1. Six connecting plates 3 are located between the two straight sections 21 of the cooling pipe 2 and are equidistantly arranged. The two ends of each connecting plate 3 are welded to the two straight sections 21 of the cooling pipe 2. The connecting plate 3 is three millimeters thick, and its welding position is located on the lower side of the two straight sections 21 of the cooling pipe 2 to avoid affecting the sliding of the copper ingot in the axial direction of the sleeve 1. Each connecting plate 3 is welded to the inner wall of the sleeve 1 to fix the cooling pipe 2 to the inner wall of the sleeve 1, preventing the cooling pipe 2 from shifting during the sliding of the copper ingot.

[0037] like Figures 1 to 5As shown, the cooling pipe 2 also includes an inlet and an outlet. Two connectors 4 are installed at the inlet and outlet respectively. Each connector 4 is located outside the sleeve 1, and its installation height is lower than the lowest point of the outer wall of the sleeve 1 to avoid affecting the movement of the copper ingot. The coolant supply equipment consists of an electric pump and a storage tank. The connectors 4 are used to connect to the coolant supply equipment. In this embodiment, the coolant is water; in other embodiments, the coolant is silicone oil or ethylene glycol. The coolant circulates within the cooling pipe 2 to cool it down, preventing thermal fatigue due to overheating during prolonged use and extending the service life of the cooling pipe 2.

[0038] The working principle of the conveyor slide of the copper ingot heating furnace provided by this utility model is summarized as follows:

[0039] First, the inlet and outlet of cooling pipe 2 are connected to the coolant supply equipment via two connectors 4, allowing the coolant to circulate within cooling pipe 2. Then, the copper ingot is pushed into sleeve 1 by the jacking device. Supported by cooling pipe 2, the copper ingot slides along the axial direction of sleeve 1. At this point, the copper ingot does not contact sleeve 1, preventing wear. After moving to a designated position, the copper ingot heats up under electromagnetic induction, and cooling pipe 2 also heats up synchronously under electromagnetic induction. At this time, the coolant inside cooling pipe 2 maintains a controlled temperature, preventing overheating.

[0040] Embodiment 2 of the conveyor slide of the copper ingot heating furnace provided by this utility model:

[0041] Its main difference from Example 1 is:

[0042] In Example 1, each of the connecting plates is welded to the inner wall of the sleeve.

[0043] In this embodiment, each connecting plate has a plug-in structure at its lower end, and a corresponding plug-in hole is provided on the side wall of the sleeve. The connecting plate is plugged into and fixed to the sleeve through the plug-in structure.

[0044] Embodiment 3 of the conveyor slide of the copper ingot heating furnace provided by this utility model:

[0045] Its main difference from Example 1 is:

[0046] In Example 1, the cooling pipe is welded to the connecting plate.

[0047] In this embodiment, the cooling pipe is welded to the inner wall of the sleeve.
