Description

[0001] The utility model relates to the technical field of magnesium alloy production and processing equipment, in particular to a drying and preheating device for magnesium alloy production. Background Art

[0002] In the production process of magnesium alloy, especially in the casting and heat treatment stages, drying and preheating are crucial steps. These steps can affect the quality of the alloy and the performance of the final product. The main purpose of drying is to remove moisture from the mold or raw materials, because magnesium alloy is very sensitive to moisture, and the presence of moisture may cause pores, cracks or other defects.

[0003] The existing drying and preheating devices for magnesium alloy production still have the following problems when in use: they usually use a preheating furnace to heat the magnesium alloy material, and the equipment should be able to accurately control the temperature and heating speed. However, since the heat source of its heating structure is located on one side of the preheating furnace, after the magnesium alloy to be dried and preheated is placed in the preheating furnace, the magnesium alloy close to the heat source end often receives more heat and affects the heating and drying of the remaining magnesium alloys. It is difficult for multiple magnesium alloys placed in the preheating furnace to be heated and dried uniformly. Utility Model Content
