Description

Technical Field

[0001] This utility model relates to the field of refining agent addition, and in particular to a refining agent addition device. Background Technology

[0002] Aluminum alloys are among the most widely used non-ferrous metal structural materials in industry, with extensive applications in aviation, aerospace, automotive, machinery manufacturing, shipbuilding, and chemical industries. The rapid development of the industrial economy has made refining agents crucial additives for degassing and slag removal in aluminum alloy smelting a key factor. Refining agents are typically forced into the bottom of the molten alloy pool using a bell jar. These bell jars are generally made of stainless steel with a coating to minimize direct contact between the bell jar and the molten alloy pool. Commercially available bell jars are typically semi-enclosed, which limits the contact between the refining agent and the molten alloy pool, resulting in an unsatisfactory reaction rate, uneven distribution, and negatively impacting the refining effect, thus affecting the performance of the castings. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a refining agent addition device, including a bell jar and a handle; the main body of the bell jar has a cylindrical cavity structure, the bottom of the main body of the bell jar is provided with a bottom injection port that is completely penetrating, and the top of the bell jar is provided with a handle in the middle; the side wall of the main body of the bell jar is provided with a side injection port, and the top of the bell jar is provided with a top injection port.

[0004] The side inlet is symmetrically arranged in two parts.

[0005] There are two symmetrically arranged top injection ports, and the top injection ports are arc-shaped through-holes.

[0006] The handle includes a vertical section, a curved section, and a force-bearing section; the top of the bell jar body is connected to the vertical section of the handle, the upper end of the vertical section is connected to the curved section, and the other end of the curved section is connected to a force-bearing section perpendicular to it.

[0007] The angle between the vertical section and the curved section is 110°.

[0008] The beneficial effects of this utility model are as follows:

[0009] Adding refining agents to this bell jar accelerates the reaction rate of the refining agents after they are pressed into the molten pool inside the bell jar. This makes the distribution of the refining agents in the molten pool more uniform during the pressing and stirring process, resulting in a more ideal refining effect of the alloy liquid, thereby improving the performance of the castings and increasing the casting qualification rate. The 110° long lever arm makes operation more labor-saving and greatly ensures the safety of the smelting workers. Attached Figure Description

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0011] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0013] See Figure 1 .

[0014] This utility model discloses a refining agent addition device, including a bell jar 1 and a handle 2; the main body of the bell jar has a cylindrical cavity structure, the bottom of the main body of the bell jar is provided with a bottom injection port 3 that is completely penetrating, and the top of the bell jar is provided with a handle in the middle; the side wall of the main body of the bell jar is provided with a side injection port 4, and the top of the bell jar is provided with a top injection port 5.

[0015] The side inlet is symmetrically arranged in two parts.

[0016] There are two symmetrically arranged top injection ports, and the top injection ports are arc-shaped through-holes.

[0017] The handle includes a vertical section 21, a curved section 22, and a force-bearing section 23; the top of the bell jar body is connected to the vertical section of the handle, the upper end of the vertical section is connected to the curved section, and the other end of the curved section is connected to a force-bearing section perpendicular to it.

[0018] The angle between the vertical section and the curved section is 110°.

[0019] By opening elongated holes at the bottom and side walls of the bell jar, the reaction method between the molten alloy in the molten pool and the refining agent is changed from bottom-pouring to bottom-pouring + top-pouring + side-pouring, which greatly accelerates the reaction rate of the refining agent. During the downward pressure process, the refining agent is continuously stirred, making the distribution of the refining agent in the molten pool more uniform. The angle between the top rod of the bell jar and the handle is changed from 90° to 110°, and the length of the lever arm is increased, which increases the operating distance between the worker and the smelting furnace.

[0020] First, the refining agent is prepared as needed and wrapped in aluminum foil to form a cylinder of the specified size for later use. The surface of the bell-type refining agent adding device is coated to reduce burn-off after being pressed into the molten pool. The smelter places the refining agent inside the bell from a safer operating distance and presses the bell into the molten pool. The molten alloy in the pool flows into the bell in a bottom-in, top-in, and side-injection manner to react with the refining agent. Simultaneously, the reacted refining agent inside the bell diffuses into the molten pool in the same manner, resulting in more uniform and rapid dispersion throughout the pool with stirring, achieving a better refining effect. This process is repeated according to the weight of the molten metal to add the required amount of refining agent, completing the refining of the aluminum alloy. This device not only better ensures the operational safety of the smelter but also ensures a more uniform distribution of the refining agent in the molten pool, a faster reaction rate, a more ideal refining effect, and better performance of the cast parts.
