Automatic-stirring smelting furnace

Abstract

The invention discloses an automatic-stirring smelting furnace. The automatic-stirring smelting furnacecomprises a furnace body, wherein a feeding inlet and a discharging outlet are arranged on the furnace body; the bottom part of the furnace body is provided with a permanent magnet stirrer; the permanent magnet stirrer is mounted on the bottom part of a smelting furnace; and the stirring operation is performed by the permanent magnet technology. Compared with manual stirring, the automatic-stirring smelting furnace has the following advantages: 1, the operation is carried out without opening a furnace door, the heat consumption is reduced, and 20% of energy consumption can be saved; 2, since the components are even and the grains are refined, the best smelting effect is achieved; 3, non-direct-contact stirring is adopted so as to avoid artificial secondary pollution, and the generation of aluminum oxide slags is reduced; 4, the smelting speed of the smelting furnace is increased; 5, the temperature difference between the surface layer and the bottom part of a smelting body normally can be controlled within 5 DEG C so as to avoid the smelting body being overheated or being over-burnt locally; and 6, the operation is simple and the workload of workers is reduced greatly.

Description

technical field [0001] The invention relates to a melting furnace, in particular to an automatic stirring melting furnace for melting aluminum alloy. Background technique [0002] Melting is one of the casting production processes. Put metal materials and other auxiliary materials into the smelting furnace to melt and temper to make them meet the requirements of pouring castings. The smelting furnaces currently used in the market do not have automatic stirring devices, and almost all use manual stirring. However, many disadvantages caused by manual stirring need to be solved urgently: [0003] 1. Uneven stirring will affect the melting effect and easily lead to local burning; [0004] 2. Destroy the protective layer of the melt covering agent and increase the alumina slag; [0005] 3. The furnace door must be opened for operation, and a large amount of heat is lost, resulting in high unit energy consumption; [0006] 4. Manual operation is not only labor-intensive, but a...
