Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical equipment, and in particular relates to a smelting flat car with a vibration platform. Background Art

[0002] The rail-type electric flat car is an auxiliary equipment for the smelting operation outside the furnace in the metallurgical industry, and is mainly used to transfer the smelting furnace. During the reaction process of the charge, the smelting furnace is the place provided for the charge reaction, and the smelting furnace is placed on the smelting flat car, so the various functions of the smelting flat car mainly serve the smelting process.

[0003] Patent document CN 201407909Y discloses a smelting flat car with a rotating disk. A rotating disk that can rotate freely and carry a smelting furnace is added to a traditional rail flat car. During smelting, the rotating disk is driven by a motor to rotate and further drives the smelting furnace to rotate synchronously, solving the problem that the smelting furnace is placed statically on the smelting flat car, resulting in the inability to adjust and control the smelting reaction speed, temperature and uniformity of the charge, thereby improving the smelting yield, quality and reducing costs.

[0004] With the development of alloy material quality, the variety and dosage of some multi-component alloys have gradually increased, and at the same time, the requirements for alloy impurities and apparent quality have become more stringent. When smelting these alloys, due to the high molten pool temperature of more than 2000℃, and the fact that stirring the furnace is not allowed to bring in other impurities, it is easy to cause defects such as pores and slag inclusions inside the alloy cake obtained by smelting. Process research shows that this problem can be effectively solved by vibrating the furnace body after the reaction of the charge, thereby driving the vibration of the molten liquid in the furnace.

[0005] Since the existing smelting flat car only has walking and rotating functions, it is extremely important to design a smelting flat car with a vibration platform to meet the process requirements and improve the quality of the alloy. Utility Model Content

[0035] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0036] According to the first aspect of the utility model, a smelting flat car with a vibrating platform is provided. Figure 1 As shown, the smelting flat car includes: a car body 1; a vibration platform 2 elastically supported on the car body 1, the vibration platform 2 is used to place the smelting furnace; a vibration mechanism 3 connected to the vibration platform 2, the vibration mechanism 3 is used to drive the vibration platform 2 to vibrate.

[0037] The smelting flat car with a vibration platform provided by the utility model can drive the vibration platform 2 to vibrate through the vibration mechanism 3, thereby driving the smelting furnace on the vibration platform 2 to vibrate, and then driving the molten liquid in the smelting furnace to vibrate, promoting the separation of the alloy and the slag and the upward migration of the gas inside the alloy, and can meet the needs of improving the quality of the alloy by the out-of-furnace method.

[0038] In some embodiments, the smelting flat car with a vibration platform further includes: a shock absorbing mechanism 4 arranged between the car body 1 and the vibration platform 2. The vibration platform 2 is elastically supported on the car body 1 through the shock absorbing mechanism 4. "Elastic support" is relative to "fixed support". "Elastic support" means that a certain degree of relative movement can occur between the vibration platform 2 and the car body 1. In contrast, "fixed support" means that there is no relative movement between the vibration platform 2 and the car body 1. The shock absorbing mechanism 4 is arranged above the car body 1 and below the vibration platform 2. The shock absorbing mechanism 4 can prevent the amplitude from being too large and prevent the molten metal in the smelting furnace from overflowing.

[0039] In the illustrated embodiment, the shock absorbing mechanism 4 is configured as a spring support column 41, one end of the spring support column 41 (the lower end in the figure) is connected to the vehicle body 1, and the other end (the upper end in the figure) is connected to the vibration platform 2. In order to stably support the vibration platform 2 and even the smelting furnace placed thereon, the number of spring support columns 41 is set to be multiple, for example, the number of spring support columns 41 can be set to three, four or more. Preferably, a plurality of spring support columns 41 are symmetrically arranged at the four corners or edge positions between the vehicle body 1 and the vibration platform 2, thereby making the vibration of the vibration platform 2 more uniform and avoiding the bumping of the smelting furnace. For example, a spring support column 41 is arranged at each of the four corner positions below the vibration platform, and a total of four spring support columns 41 are arranged.

[0040] In other embodiments, the shock absorbing mechanism 4 may also be configured in other forms, for example, as a rubber buffer, a hydraulic buffer, etc.

[0041] In some embodiments, the vibration mechanism 3 includes a vibration motor 31, which is connected to the vibration platform 2 and is used to provide vibration force to the vibration platform 2. In the illustrated embodiment, the vibration motor 31 is arranged below the vibration platform 2. Preferably, in order to provide stable vibration to the vibration platform 2, the number of the vibration motors 31 is set to be multiple, and the multiple vibration motors 31 are arranged in a space surrounded by multiple spring support columns 41.

[0042] In some embodiments, a fixed stop mechanism 21 for fixing the smelting furnace is provided on the vibration platform 2. The fixed stop mechanism 21 can be provided in the form of a fixed stop block, for example. A plurality of fixed stop blocks can be provided on the vibration platform 2, and the smelting furnace is fixed on the vibration platform 2 via the plurality of fixed stop blocks.

[0043] In some embodiments, a heat insulating material layer is laid on the vibration platform 2 to prevent the high temperature of the smelting furnace from damaging the components (eg, the vibration motor 31) located below the vibration platform 2. For example, the heat insulating material layer can be set as a heat insulating magnesium brick.

[0044] In some embodiments, the smelting flat car with a vibration platform further includes: wheels 5 arranged under the car body 1; a power system connected to the wheels 5, the power system is used to provide power to the wheels 5. The arrangement of the wheels 5 and the power system can facilitate the transportation of the smelting furnace to the working area, with flexible movement, no need for manual handling, and greatly reducing labor intensity. The number of wheels 5 is set to multiple, preferably four, and symmetrically arranged on both sides of the car body 1.

[0045] In some embodiments, the vehicle body 1 includes a bottom plate for connecting to the shock absorbing mechanism 4, the wheels 5 are arranged at the lower end of the bottom plate, and the power system is arranged on the lower side of the bottom plate.

[0046] When the smelting flat car with a vibration platform provided by the utility model is working, the smelting furnace is placed on the vibration platform 2 (for example, placed inside the fixed limit block on the upper part of the vibration platform 2), and the vibration mechanism 3 (for example, the vibration motor 31) is turned on according to the process requirements. Under the vibration action of the vibration mechanism 3, the molten metal in the smelting furnace vibrates, which promotes the separation of the alloy and slag in the smelting furnace and the upward migration of the gas inside the alloy, effectively preventing the defects such as pores and slag inclusions inside the alloy cake obtained by smelting, which is conducive to improving the quality of the alloy. In some cases, the vibration frequency of the vibration mechanism 3 can be adjusted to control the vibration frequency of the molten metal in the smelting furnace, thereby controlling the upward migration rate of the gas.
