Problems solved by technology
However, magnesium alloys are flammable and easy to oxidize, and more oxidation defects are easily introduced during the preparation process. For particle-reinforced magnesium-based composites, the stirring process is inevitable in order to make the reinforcement uniformly dispersed in the magnesium alloy matrix. It brings great difficulties to the preparation process of magnesium matrix composites
At present, the equipment used to prepare particle-reinforced magnesium-based composite materials is a traditional high-temperature melting furnace. The stirring process uses a stirrer separate from the furnace body. This step is very easy to introduce air to react with magnesium to form inclusions, and the stirring blades are rotated into the melt.

The present invention relates to the technical field of melting furnaces, in particular to a melting and stirring integrated high-temperature melting furnace for the preparation of magnesium-based composite materials, which includes: a crucible for containing materials; a main body for containing the crucible; a cover set on the main body The top seals the accommodation space of the main body; it also includes a stirring unit, which has a first state of stirring the materials in the crucible, and a second state connected to the cover and away from the crucible; the power unit drives the stirring unit to perform linear motion To achieve switching between the first state and the second state, and provide rotational power for the stirring unit. In the present invention, a stirring unit is provided which is always located in the sealed space limited by the cover body and the main body. Through the conversion of the two states, the implementation of the stirring action and the storage state can be realized respectively. Through the improvement of the stirring unit, it can effectively reduce the The possibility of introducing air, so as to avoid the reaction of air and magnesium to form inclusions, and rotate into the melt with the stirring blade.
Description
technical field [0001] The invention relates to the technical field of smelting furnaces, in particular to an integrated smelting and stirring high-temperature melting furnace for the preparation of magnesium-based composite materials. Background technique [0002] Magnesium alloy is the lightest metal material in engineering applications, and has broad development prospects in aerospace and automobile industries. The preparation of magnesium-based composites, which aims to enhance the strength of magnesium alloys, is favored by many researchers. However, magnesium alloys are flammable and easy to oxidize, and more oxidation defects are easily introduced during the preparation process. For particle-reinforced magnesium-based composites, the stirring process is inevitable in order to make the reinforcement uniformly dispersed in the magnesium alloy matrix. It brings great difficulties to the preparation process of magnesium-based composite materials. At present, the equipme...
