Description

Technical Field

[0001] The utility model relates to the field of aluminum ingot production, in particular to a crystallization aluminum ingot lifting device. Background Art

[0002] Crystallization is a short-process, high-efficiency, low-pollution high-purity aluminum preparation technology. It is an application extension of directional solidification technology in the industrialization process, and is particularly suitable for the preparation of electronic-grade high-purity aluminum. The specific process of the crystallization method is: insert a crystallization axis with rotation and cooling functions into the high-temperature aluminum liquid, pass a cooling medium into the crystallization axis, and control the temperature gradient to cause the aluminum liquid to continuously crystallize and accumulate on the surface of the crystallization axis. At the same time, the crystallization axis is started to rotate, which, on the one hand, reduces the thickness of the impurity element enrichment layer near the solid-liquid interface, and on the other hand, accelerates the diffusion rate of the impurity elements and improves the purification effect.

[0003] The crystallized aluminum ingot made by the crystallization method has an opening at the upper end formed by the crystallization axis and a spherical surface formed by rotation at the lower end. The crystallized aluminum ingot is usually placed in a horizontal lying form due to the spherical surface at the lower end. Before lifting and transportation, the crystallized aluminum ingot usually needs to be erected to achieve grabbing and lifting. In addition, the outer circumferential surface of the crystallized aluminum ingot usually has an arc, and the upper end diameter is usually larger than the lower end diameter. The aluminum ingot lifting tools in the prior art are usually clamped and lifted, which are not suitable for crystallized aluminum ingots. For example, the patent with authorization announcement number CN210150581U discloses an aluminum ingot lifting clamp, whose reference part is provided with symmetrically distributed clamping arms, and the aluminum ingot is clamped and lifted by the clamping arms when in use. For example, the patent with authorization announcement number CN214733844U also discloses an aluminum ingot lifting clamp, which also has a first clamping arm and a second clamping arm symmetrically hinged on a fixed seat to complete the clamping and lifting and transportation of the aluminum ingot.
