[0002] In the amorphous and nanocrystalline ribbon industry, smelting equipment is a key component in ribbon preparation. Based on current process requirements for amorphous / nanocrystalline ribbon production, medium-frequency induction furnaces are typically used for smelting due to their advantages of low pollution and high efficiency. Considering requirements for feeding, ease of operation, and steel purification, the furnace tonnage is usually below 10 tons, with a maximum single-batch molten steel weight of 10 tons. Only after the molten steel has been cast can it be re-fed for smelting.

[0003] In summary, existing smelting and casting equipment suffers from problems such as limited single-spray pouring capacity, inability to operate continuously resulting in ineffective cycles between sprays, and low overall production line efficiency. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments provided by this utility model without inventive effort are within the scope of protection of this utility model.

[0024] This utility model discloses a continuous smelting and casting equipment, comprising: a smelting furnace 1; a casting furnace 2 having a steel inlet; a guide channel 3 located at the front end of the smelting furnace 1 and between the smelting furnace 1 and the casting furnace 2; a smelting furnace carrier 4, which moves the smelting furnace 1 to a smelting position for feeding and smelting, and moves the smelting furnace 1 to a continuous steel supply position for conveying molten steel in the smelting furnace 1 through the guide channel 3 and the steel inlet to the casting furnace 2; a casting furnace carrier 5, which moves the casting furnace 2 to a receiving position for conveying molten steel in the smelting furnace 1 through the guide channel 3 and the steel inlet to the casting furnace 2, and moves the casting furnace 2 to a casting position for casting molten steel in the casting furnace 2; the smelting position, the receiving position, the continuous steel supply position, and the casting position are arranged sequentially in a straight line.

[0025] The aforementioned continuous smelting and casting equipment utilizes a guide channel 3 between the smelting furnace 1 and the casting furnace 2. The smelting furnace 1 is moved by a carrier 4, and the casting furnace 2 is moved by a carrier 5. Through the coordinated operation of these furnaces, long-term continuous operation is achieved, enabling continuous smelting and casting and improving operational efficiency. Specifically, the smelting furnace 1 is used for raw material smelting, and the casting furnace 2 is used for casting. While the casting furnace 2 is performing casting operations, the smelting furnace can simultaneously perform smelting operations. Furthermore, the guide channel 3 continuously replenishes the molten steel in the casting furnace 2, allowing for longer continuous casting operations and increasing the equipment's effective operating rate.

[0026] To further ensure operational efficiency, the melting efficiency of the above-mentioned smelting furnace 1 is sufficient to melt the raw materials into molten steel before the molten steel in the casting furnace 2 is finished. The capacity of smelting furnace 1 and casting furnace 2 can be configured according to the casting efficiency.

[0027] In some embodiments, a movable component 8 is also included. One end of the movable component 8 is connected to the bottom of the guide channel 3. The movable component 8 extends and retracts, causing the guide channel 3 to rotate up and down around the end of the guide channel 3 near the smelting furnace 1. It is understood that the movable component 8 can be a cylinder, a hydraulic cylinder, or a motor. When the movable component 8 is a cylinder, one end of the piston rod of the cylinder is connected to the bottom of the guide channel 3. The piston rod extends and retracts, causing the guide channel 3 to rotate up and down around the end of the guide channel 3 near the smelting furnace 1. The guide channel 3 can connect to the steel receiving port on the furnace cover of the casting furnace 2. The guide channel 3 has a certain inclination angle to facilitate the passage of molten steel.

[0028] In addition, to facilitate the transfer of molten steel from the smelting furnace 1 to the casting furnace 2 via the guide channel 3, the smelting furnace 1 can be tilted 90° to pour the molten steel into the casting furnace 2 through the guide channel 3. The casting furnace 2 adopts a bottom tapping casting method. To achieve the tilting of the smelting furnace 1, existing tilting structures can be used, including but not limited to tilting hinges and lifting cylinders.

[0029] In some embodiments, a steel receiving device 7 is also included, located at the casting position and below the casting furnace 2, and the casting furnace 2 pours molten steel into the steel receiving device 7 by bottom pouring.

[0030] In some embodiments, a guide rail 6 is also included, along which the smelting furnace carrier 4 and the casting furnace carrier 5 move. The smelting furnace 1 is mounted on the smelting furnace carrier 4 (which can be a smelting furnace moving vehicle), and the smelting furnace carrier 4 can move back and forth along the guide rail 6; the casting furnace 2 is mounted on the casting furnace carrier 5 (which can be a casting furnace 2 moving vehicle), and the casting furnace carrier 5 shares the guide rail 6 with the smelting furnace carrier, and can move back and forth along the guide rail 6.

[0031] like Figure 1 As shown, when the smelting furnace 1 is in the smelting position and the casting furnace 2 is in the receiving position, the guide trough 3 connects the smelting furnace 1 and the casting furnace 2, and transports the molten steel in the smelting furnace 1 to the casting furnace 2 through the receiving port. Specifically, when the smelting furnace 1 is in the smelting position and the casting furnace 2 is in the receiving position, the piston rod retracts and drives the guide trough 3 to rotate downwards until the end of the guide trough 3 near the casting furnace 2 is lower than the end of the guide trough 3 near the smelting furnace 1. The guide trough 3 connects the smelting furnace 1 and the casting furnace 2, and transports the molten steel in the smelting furnace 1 to the casting furnace 2 through the receiving port.

[0032] like Figure 2As shown, when the smelting furnace 1 is in the smelting position and the casting furnace 2 is in the casting position, the smelting furnace 1 is charged and smelted, and the molten steel in the casting furnace 2 is cast. Specifically, when the smelting furnace 1 is in the smelting position and the casting furnace 2 is in the casting position, the piston rod extends and drives the guide trough 3 to rotate upward until the end of the guide trough 3 near the casting furnace 2 is higher than the end of the guide trough 3 near the smelting furnace 1.

[0033] like Figure 3 As shown, when the smelting furnace 1 is in the continuous steel supply position and the casting furnace 2 is in the casting position, the guide trough 3 connects the smelting furnace 1 and the casting furnace 2, and transports the molten steel in the smelting furnace 1 to the casting furnace 2 through the steel receiving port. Specifically, when the smelting furnace 1 is in the continuous steel supply position and the casting furnace 2 is in the casting position, the piston rod retracts and drives the guide trough 3 to rotate downwards until the end of the guide trough 3 near the casting furnace 2 is lower than the end of the guide trough 3 near the smelting furnace 1. The guide trough 3 connects the smelting furnace 1 and the casting furnace 2, and transports the molten steel in the smelting furnace 1 to the casting furnace 2 through the steel receiving port.

[0034] The working process of the above-mentioned continuous melting and casting equipment is as follows:

[0035] Continue to refer to Figure 1 The smelting furnace 1 is charged at the smelting position for smelting, and the casting furnace 2 is at the steel receiving position. The steel receiving port on the furnace cover of the casting furnace 2 is connected to the guide channel 3. After the molten steel in the smelting furnace 1 is smelted, the molten steel is transferred to the casting furnace 2 through the guide channel 3. After the molten steel in the smelting furnace 1 is discharged, the raw materials are refilled and the smelting begins again.

[0036] like Figure 2 One end of the guide channel 3 rises and separates from the casting furnace 2. The casting furnace carrier 5 moves along the guide rail 6 to the casting position. The casting furnace 2 pours molten steel into the steel receiving device 7 by bottom pouring. At the same time, the smelting furnace 1 is smelting molten steel.

[0037] like Figure 3 As shown, after the steel in the smelting furnace 1 is melted, the smelting furnace carrier 4 moves to the steel feeding position, and one end of the guide trough 3 lowers to connect with the steel receiving port of the casting furnace 2. The molten steel is then transferred to the casting furnace 2 through the guide trough 3, allowing the casting furnace 2 to continuously perform casting operations. When the guide trough 3 is raised, the smelting furnace carrier 4 moves to the smelting position, and the smelting furnace 1 is refilled for smelting. This cycle repeats, allowing the casting furnace 2 to continuously perform casting operations for an extended period of time.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
