Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum liquid refining outside the furnace, in particular to an aluminum smelting outside the furnace refining equipment for casting and rolling. Background Art

[0002] Aluminum refining is a crucial process for improving the quality of molten aluminum. After the aluminum alloy is melted at high temperatures, it is prone to forming lead oxide crystals on the surface of the mold. These crystals can seriously affect the smoothness of the aluminum alloy during molding, so they must be scraped off before die-casting.

[0003] Comparatively, Chinese patent publication number CN212191222U discloses an off-furnace refining device for aluminum smelting for casting and rolling, comprising a retaining ring, a chain transmission device, and a billet refining mechanism. The outer ends of the support ring are further connected to first and second outer racks via L-shaped support plates. The base is further provided with first and second inner racks. A discharge port is provided at the other flat end of the top of the base, and first and second flip racks are provided at the upper outer ends of the discharge port. A linkage gear engages with the racks, causing a scraper to scrape out alumina slag in the ladder trough driven by a threaded rod. The flip gear engages with the first flip rack, causing the billet refining mechanism to flip downward, disengaging the aluminum ingot. The flip gear engages with the second flip rack, driving the billet refining mechanism to flip back to its original position. The linkage gear again engages with another rack, causing the scraper to return to the upper side of the inner end partition driven by the threaded rod, without requiring manual intervention.

[0004] However, the above patent adopts a single-end force-pulling and moving setting, which results in uneven force, seriously affecting the maintenance cycle and service life. In addition, the aluminum oxide is only scraped off once at one end, and the thoroughness of the aluminum oxide scraping cannot be guaranteed. Therefore, a new device needs to be designed.
