Technical Field

[0001] The utility model relates to the technical field of casting furnaces, in particular to a high-efficiency continuous casting furnace. Background Art

[0002] In the production of copper casting, some copper raw materials are put into a furnace, and the furnace melts the copper raw materials inside the furnace through high-frequency heating to form copper liquid.

[0003] In order to facilitate pouring the molten copper from the furnace into the container, the furnace is set to be flippable. Therefore, the molten copper inside the furnace can be poured into the container by rotating the furnace to a certain angle. Then, the molten copper is injected into the mold through the container, thereby obtaining a product of the desired shape.

[0004] However, after the existing copper raw materials are melted, there is an action of pouring the copper liquid, which makes it impossible to continuously put them into the melting furnace for melting, and the waiting time is long, which makes the melting efficiency low. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a high-efficiency continuous casting furnace, which can continuously input copper raw materials for melting, reduce pause and waiting time, and improve melting efficiency.

[0009] According to some embodiments of the present invention, a vertical partition plate is provided in the second crucible, two ends of the partition plate are connected to two opposite inner side walls of the second crucible, and the bottom end of the partition plate is suspended.

[0010] According to some embodiments of the utility model, the first power member includes a sprocket located above the gate, a chain transmission connected to the sprocket, and a cylinder located on a horizontal side of the sprocket, one end of the chain is connected to the telescopic end of the cylinder, and the other end of the chain is connected to the top of the gate.

[0011] According to some embodiments of the present invention, the invention further includes a melting chamber and a smoke exhaust pipe connected to the melting chamber, and the inner cavity of the melting chamber accommodates the melting furnace.

[0012] According to some embodiments of the present invention, refractory bricks are arranged on the outside of the melting furnace, and the refractory bricks are stacked to form the melting chamber.

[0014] A high-efficiency continuous casting furnace according to an embodiment of the utility model has at least the following beneficial effects:

[0015] 1. The utility model provides a first crucible, a first heating coil and a liquid outlet channel. After the first heating coil is energized, the copper raw material inside the first crucible is melted by high-frequency electric heating to obtain copper liquid. The copper liquid can flow into the insulation furnace through the liquid outlet channel. Therefore, the copper raw material can be continuously added for heating and melting.

[0016] 2. The utility model provides a second crucible and a second heating coil. Since the second crucible is located below the first crucible, the second crucible can receive the copper liquid naturally flowing out of the first crucible. After the second heating coil is energized, the copper liquid inside the second crucible is heated and kept warm by high-frequency electric heating to keep the copper liquid in a liquid state. Therefore, the copper liquid can be extracted from the second crucible using a container and can be injected into multiple molds at the same time to meet production needs. At the same time, the temperature of the second crucible can be lower than the temperature in the first crucible.

[0017] 3. The utility model provides a gate and a first power member, so that after the copper raw material inside the first crucible is completely melted, the first power member drives the gate to rise, so that the copper liquid in the first crucible flows into the second crucible through the liquid outlet channel. When the copper raw material is put into melting again, the first power member drives the gate to descend, so that some raw material particles that are not completely melted cannot enter the second crucible, thereby ensuring the quality of the copper liquid in the second crucible. Therefore, the copper liquid can be continuously supplied to the insulation furnace, so that the copper liquid in the insulation furnace is sufficient, the pause and waiting time are reduced, and the melting efficiency is improved.

The drainage groove 180 is connected to the liquid outlet channel 130 , and the low point of the drainage groove 180 is disposed close to the top of the second crucible 140 .

[0032] Therefore, the copper liquid in the first crucible 110 is guided into the second crucible 140 through the drainage groove 180 , so as to prevent the copper liquid from splashing when falling into the second crucible 140 .

[0033] In some embodiments of the present invention, a vertical partition plate 190 is disposed in the second crucible 140 , two ends of the partition plate 190 are connected to two opposite inner side walls of the second crucible 140 , and the bottom end of the partition plate 190 is suspended.

[0034] Therefore, one side of the partition plate 190 can isolate the debris on the surface of the copper liquid in the second crucible 140 , making it convenient for operators to extract purer copper liquid on the other side of the partition plate 190 .

[0035] In some embodiments of the present invention, referring to Figure 2 The first power component includes a sprocket 200 located above the gate 160, a chain 210 drivingly connected to the sprocket 200, and a cylinder 220 located on a horizontal side of the sprocket 200, one end of the chain 210 is connected to the telescopic end of the cylinder 220, and the other end of the chain 210 is connected to the top of the gate 160.

[0043] 2. The utility model provides a second crucible 140 and a second heating coil 150. Since the second crucible 140 is located below the first crucible 110, the second crucible 140 can receive the copper liquid naturally flowing out of the first crucible 110. After the second heating coil 150 is powered on, the copper liquid inside the second crucible 140 is heated and kept warm by high-frequency electric heating to keep the copper liquid in a liquid state. Therefore, the copper liquid can be extracted from the second crucible 140 using a container and can be injected into multiple molds at the same time to meet production needs. At the same time, the temperature of the second crucible 140 can be lower than the temperature in the first crucible 110. It is sufficient that the temperature of the second crucible 140 can keep the copper liquid in a liquid state, thereby reducing energy consumption.

[0044] 3. The utility model provides a gate 160 and a first power member, so that after the copper raw material inside the first crucible 110 is completely melted, the first power member drives the gate 160 to rise, so that the copper liquid in the first crucible 110 flows into the second crucible 140 through the liquid outlet channel 130.
