Description

Technical Field

[0001] The utility model relates to the technical field of smelting furnace equipment, in particular to an electromagnetic flow guide device for a casting and rolling furnace. Background Art

[0002] Melting furnaces are important equipment for melting and heating metals or metal alloys. They are widely used in the chemical industry. They are mainly used for melting and heating precious metals such as gold, platinum, silver, copper, iron, stainless steel, aluminum alloys, aluminum and other metals. The raw materials are melted into liquid at high temperature in the melting furnace to remove impurities, and then the metal is precipitated by adding electrolyte and other means.

[0003] Before aluminum is cast, it must be smelted first. The smelted aluminum liquid flows from the discharge port of the smelting furnace through the guide groove for subsequent processing. Among them, the aluminum slag remaining in the smelting furnace is easily discharged into the guide groove together with the aluminum liquid through the discharge port, resulting in a high content of impurity solids in the aluminum liquid, affecting the quality of the cast and rolled aluminum products. In addition, when transporting the molten metal in the smelting furnace, most mechanical pumps are used to transport the molten metal in the smelting furnace. In the process of transporting the molten metal, slag and lumps will appear on the mechanical pump, resulting in the mechanical pump running smoothly. It is necessary to clean the rotor slag of the mechanical pump every day, and the manual workload is large. Summary of the invention

[0004] In order to solve the problem that the aluminum slag remaining in the existing smelting furnace is easily discharged into the diversion trough together with the aluminum liquid through the discharge port, resulting in a high content of impurity solids in the aluminum liquid, affecting the quality of the cast and rolled aluminum products; at the same time, in the process of transporting the molten metal, the mechanical pump will produce slagging and lumps, resulting in the mechanical pump running unsmoothly, and the rotor slagging of the mechanical pump needs to be cleaned every day, resulting in a large amount of manual workload, the utility model proposes an electromagnetic diversion device for a casting and rolling furnace, which lifts the molten metal into the diversion channel through a conveying mechanism arranged between the solution inlet of the diversion channel and the smelting furnace one, reduces the aluminum slag entering the diversion channel, and drives the molten metal flowing into the inlet of the diversion channel through the diversion channel through a magnetic field generator two circumferentially arranged in the diversion channel to finally enter the smelting furnace two through the diversion channel, thereby avoiding the slagging phenomenon when the mechanical pump contacts the molten metal when providing power, thereby reducing the manual workload.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: an electromagnetic flow diversion device for a casting and rolling furnace, comprising a casting and rolling double-chamber furnace and a flow diversion channel, the casting and rolling double-chamber furnace comprising smelting furnace one and smelting furnace two, a conveying mechanism is provided between the flow diversion channel and the smelting furnace one, the conveying mechanism comprises a riser pipe and a magnetic field generator one, the solution outlet of the smelting furnace one is located at the lower side of the riser pipe, one end of the riser pipe is connected to the solution outlet of the smelting furnace one, and the other end is connected to the solution inlet of the flow diversion channel, the magnetic field generator one is arranged on the side of the riser pipe, and the magnetic field generator two is arranged circumferentially of the flow diversion channel. The conveying mechanism is used to lift the molten metal flowing out of the solution outlet of smelting furnace one into the guide channel. The magnetic field generator one can generate a magnetic field, and under the action of the magnetic field, the molten metal flowing out of the solution outlet of smelting furnace one can be driven to enter the guide channel through the riser pipe. The magnetic field generator two can generate a magnetic field, and under the action of the magnetic field, the molten metal flowing in from the inlet of the guide channel can be driven to enter the guide channel through the guide channel and finally enter the smelting furnace two. Magnetic field generator one is provided on both sides of the riser pipe. The magnetic force generated by the magnetic field generator one lifts the molten metal to a specified height. The magnetic field generator one generates an upward traveling wave magnetic field under the control of the frequency conversion unit, driving the aluminum solution to move upward. The metal solution inlet of the riser pipe is connected to the solution outlet of smelting furnace one. When the solution outlet of smelting furnace one is opened, the metal solution can flow into the riser pipe and then be transported to the guide channel through the conveying mechanism.

[0006] Furthermore, an interface plate is provided between the solution outlet of the riser and the solution inlet of the guide channel, and the interface plate is used to block the gap between the solution inlet of the guide channel and the solution outlet of the riser. The shape of the interface plate matches the shape of the gap and can block the gap.

[0007] Furthermore, a support seat is provided below the guide channel, a second magnetic field generator is provided inside the support seat, a fixing block is provided on the side of the guide channel, and the fixing block is fixed to the support seat by bolts. A second magnetic field generator is symmetrically provided inside the support seat, and the second magnetic field generator is located on both sides of the guide channel. The fixing block is fixed to the side of the guide channel and fixed to the support seat by bolts to achieve stability of the guide channel.

[0008] Furthermore, the guide channel is open on the upper side, is "U"-shaped, and has a "concave"-shaped cross section.

[0009] Furthermore, the support seat matches the shape of the guide channel, and the support seat is "U"-shaped and the cross-section is "concave"-shaped.

[0010] Furthermore, a liquid outlet is provided on the side of the riser pipe. If the molten metal in the smelting furnace has been completely transported, there will be a small amount of residual molten metal in the riser pipe that cannot be transported to the guide channel. If there is no new molten metal replenished in a short time, the molten metal will solidify. To avoid this situation, the molten metal in the riser pipe must be emptied. For this purpose, a liquid outlet needs to be provided below the riser pipe to facilitate the discharge of the remaining molten metal in the pipe.

[0011] Furthermore, the magnetic field generator one or the magnetic field generator two is a solenoid coil.

[0012] Through the above technical scheme, the beneficial effects of the utility model are as follows: the utility model lifts the molten metal into the guide channel through the magnetic field generator 1 arranged on both sides of the riser, reduces the metal slag entering the guide channel, and ensures the quality of the molten metal. At the same time, the magnetic force generated by the magnetic field generator 2 arranged on both sides of the guide channel can drive the molten metal flowing into the guide channel inlet through the guide channel and finally enter the smelting furnace 2, avoiding the slagging phenomenon caused by the mechanical pump contacting the molten metal when providing power, reducing the manpower workload and improving efficiency.

As shown Figure 2 A magnetic field generator 5 is provided on both sides of the riser tube 4. In this embodiment, the solution outlet of the riser tube 4 is located at the upper part of the riser tube 4.

[0020] A support seat 8 is provided below the guide channel 1, and a magnetic field generator 6 is provided inside the support seat 8. The magnetic field generator 6 can generate a magnetic field, and under the action of the magnetic field, the metal solution flowing from the inlet of the guide channel 1 can be driven to pass through the guide channel 1 and finally enter the smelting furnace 3. Figure 4 As shown, the support seat 8 is located below the guide channel 1, and a second magnetic field generator 6 is symmetrically arranged inside the support seat 8.

[0021] The magnetic field generator 1 5 or the magnetic field generator 2 6 is an electromagnetic coil, such as a solenoid coil. When an alternating current is passed through the solenoid coil, the molten metal flows under the action of the electromagnetic force. Under the action of the magnetic field generator 1 5 , the molten metal is lifted to the entrance of the guide channel 1 , and at the same time, the magnetic field generator 2 6 drives the molten metal in the guide channel 1 to flow into the smelting furnace 2 3 along the set direction.
