Description

Technical Field

[0001] The utility model relates to the technical field of smelting equipment, in particular to an electric heating type tundish baking device. Background Art

[0002] The tundish is a refractory container used in mini-process steelmaking. It first receives molten steel from the ladle and then pours it into molds through the tundish nozzle to continuously form slabs, billets, beams, and other products. Dry charge is a new type of refractory material. Due to its advantages such as long life, ease of construction, and ease of disassembly, the tundish working layer of continuous casting machines made with dry charge has gained widespread application in recent years. The tundish working layer of dry charge continuous casting machines, or the dry charge layer, is typically constructed using a baking machine equipped with a baking and vibration device. The dry charge needs to be vibrated and heated to strengthen it. However, existing baking machines typically use gas flames for heating, which not only results in uneven heating and low thermal efficiency, but also poses safety risks such as gas leaks and explosions.

[0005] An electrically heated tundish roaster comprises a roaster body, wherein the roaster body is provided with a cavity with an open bottom, and a plurality of groups of electric heating tubes are laid on the inner wall of the side of the roaster body.

[0006] As a further improvement of the above technical solution:

[0007] The inner wall of the side of the roaster body is provided with multiple groups of horizontal ribs and multiple groups of vertical ribs. The horizontal ribs and the vertical ribs are staggered to form several groups of grid units. The electric heating tube is arranged in each group of the grid units.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1 and Figure 2 As shown, the electrically heated tundish roaster of this embodiment includes a roaster body 1 having a bottom-open cavity therein. Several groups of electric heating tubes 2 are laid along the inner side walls of the roaster body 1. By laying the electric heating tubes 2 along the inner side walls of the roaster body 1, this electrically heated tundish roaster replaces the conventional gas flame heating solution. By adjusting the heating power of the electric heating tubes 2, the heating temperature of the outer side walls can be effectively controlled, resulting in a more uniform heating temperature along the outer side walls of the roaster body 1, thereby improving the heating efficiency of the roaster body 1 and eliminating the safety hazard of gas leakage and explosion. The result is a highly user-friendly and safe system.

[0019] Preferably, the side inner wall of the roaster body 1 is provided with multiple sets of transverse ribs 3 and multiple sets of vertical ribs 4. These ribs 3 and 4 are staggered to form several grid cells, each of which houses an electric heating tube 2. In this embodiment, the side inner wall of the roaster body 1 is formed into a multiple grid cell framework by the transverse ribs 3 and vertical ribs 4. This improves the structural strength of the roaster body 1, reduces deformation of the side, and increases its service life. Furthermore, the electric heating tubes 2 are arranged within the grid cell framework, creating a grid-like distribution of heating areas. This allows the temperature of different areas to be adjusted according to actual application requirements, resulting in high flexibility and a wide range of applications.

[0020] Preferably, the top of the roaster body 1 is provided with several groups of hanging beams 5, and the hanging beams 5 are provided with several groups of lifting lugs 6. In this embodiment, the number of groups of hanging beams 5 is set to two, and the two groups of hanging beams 5 are respectively provided on both sides of the roaster body 1. The number of groups of lifting lugs 6 is set to four, and the two groups of lifting lugs 6 are respectively provided at both ends of one group of hanging beams 5. This facilitates the hoisting equipment to transfer the roaster body 1 through the lifting lugs 6 and the hanging beams 5, ensures uniform force distribution during lifting, and prevents the roaster body 1 from tilting when dropping or releasing the mold, thereby improving stability.

[0021] Preferably, a plurality of vibration motor mounting brackets 7 are provided on the top of the roaster body 1. In this embodiment, the number of vibration motor mounting brackets 7 is set to three, and the vibration motor is installed on the vibration motor mounting brackets 7. In actual use, the roaster body 1 is first placed in the tundish, and then the dry material is filled into the gap between the roaster body 1 and the tundish. The vibration motor is started to vibrate the dry material, and then the electric heating tube 2 bakes the dry material. After baking is completed, the roaster body 1 is lifted and demolded, completing the masonry of the dry material layer.

[0022] Preferably, a plurality of smoke and moisture exhaust pipes 8 are further provided on the top of the roaster body 1. In this embodiment, the number of smoke and moisture exhaust pipes 8 is set to six, with two sets of smoke and moisture exhaust pipes 8 provided on both sides and in the middle of the roaster body 1, respectively, to facilitate exhausting smoke and steam from the roaster body 1 through the smoke and moisture exhaust pipes 8.

[0023] The above is only a preferred embodiment of the present invention, and the scope of protection of the present invention is not limited to the above embodiment. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of the present invention should also be considered as the scope of protection of the present invention.
