Description

Technical Field

[0001] The utility model relates to the technical field of buried aluminizing furnaces, in particular to a buried aluminizing furnace. Background Art

[0002] A buried aluminizing furnace is a specialized device used for aluminizing. Its design features a buried furnace body, enabling a specialized heating and aluminizing process. The operating principle of a buried aluminizing furnace is based on electromagnetic induction heating and the aluminizing reaction. During the aluminizing process, an induction coil generates heat through electromagnetic induction, heating the molten aluminum within the furnace lining to a specific temperature. The workpiece is clamped in a fixture and fed into the furnace, where it comes into contact with the hot molten aluminum. At this high temperature, aluminum atoms in the molten aluminum diffuse into the workpiece surface, forming a dense aluminide coating.
