Embodiment 1
[0048] This embodiment provides a device for adding refining agent, see Figure 1 to Figure 2 , including a storage tank 1, a stirring mechanism, and a lifting mechanism (not shown in the figure) for driving the storage tank 1 and the stirring mechanism to lift. For example, aluminum alloy refining agent, the slot of the storage tank 1 and the through hole 2 serve as the circulation channel of the refining agent.
[0049] During implementation, the lifting mechanism is activated, and the lifting mechanism drives the storage tank 1 and the stirring mechanism to move toward the molten pool, and finally enters the molten pool, close to the bottom of the molten pool; close the lifting mechanism, open the stirring mechanism, and under the stirring action of the stirring mechanism, The melt in the molten pool flows between the inside and outside of the storage tank 1, and at the same time, the refining agent in the storage tank 1 is taken out of the storage tank 1 and dissolved in t...
Embodiment 2
[0072] This embodiment provides a method for adding a refining agent, using the method for adding a refining agent provided in Embodiment 1, and the above-mentioned adding method includes the following steps:
[0073] Step S1: start the lifting mechanism, the lifting mechanism drives the storage tank 1 and the stirring mechanism to move towards the direction close to the molten pool, and enters the molten pool, close to the bottom of the molten pool;
[0074] Step S2: closing the lifting mechanism, opening the stirring mechanism, and under the stirring action of the stirring mechanism, the refining agent in the storage tank 1 is taken out of the storage tank 1 and dissolved in the melt, thereby completing the addition of the refining agent.
[0075] Compared with the prior art, the beneficial effects of the refining agent adding method provided in this embodiment are basically the same as the beneficial effects of the refining agent adding device provided in the first embodimen...

Abstract
The invention discloses a refining agent adding device and adding method, which belong to the technical field of alloy smelting and solve the problems of iron increase or poor refining effect in the refining process in the prior art. The adding device of the present invention includes a storage tank, a stirring mechanism and a lifting mechanism for driving the storage tank and the stirring mechanism to lift up and down. The storage tank is provided with a through hole with the notch facing downward, and the storage tank is filled with refining agent. The adding method of the present invention comprises the following steps: start the lifting mechanism, the lifting mechanism drives the storage tank and the stirring mechanism to move towards the direction close to the molten pool, and enter the molten pool, close to the bottom of the molten pool; close the lifting mechanism, open the stirring mechanism, and Under the action of stirring, the refining agent in the storage tank is taken out of the storage tank and dissolved in the melt, thereby completing the addition of the refining agent. The adding device and adding method of the present invention can be used for adding refining agent.
Description
technical field [0001] The invention belongs to the technical field of alloy smelting, and particularly relates to a refining agent adding device and adding method. Background technique [0002] Refining agent is a key additive for degassing and slag removal in aluminum alloy smelting. The refining agent usually adopts the following two methods: one of the methods is to use a bell jar to press the refining agent into the bottom of the alloy molten pool. The bell jar is generally made of stainless steel coating to reduce the direct contact between the bell jar and the alloy molten pool. However, in the refining process, there is still ablation of the bell jar, which leads to the increase of iron in the alloy molten pool and the deterioration of the molten pool composition, which affects the performance of the casting. In another way, the refining agent is sent to the bottom of the alloy molten pool by compressed gas. During the process of sending the refining agent to the bo...
