Embodiment Construction
[0048] The method for in-line straightening and strengthening of magnesium alloy extruded materials using waste heat according to the present invention will be further explained and explained below in conjunction with the accompanying drawings and specific embodiments of the description. The technical solution constitutes an improper limitation.
[0049] figure 1 The process of preparing by using the method for in-line straightening and strengthening of magnesium alloy extruded material by using waste heat according to the present invention is schematically shown.
[0050] like figure 1 As shown, in the extrusion process, the ingot is heated to a set temperature by induction, and the set temperature can be between 350°C and 450°C according to different alloy compositions. Heating is performed by the extrusion cylinder, and the heating temperature of the extrusion cylinder is the same as the set heating temperature of the ingot. The mold is heated in a heating furnace, and a...

Abstract
The invention discloses a method for on-line straightening and strengthening of magnesium alloy extruded material by using residual temperature, which comprises the steps of: applying a set traction force to the magnesium alloy extruded material downstream of the outlet end of the extruder, so that The magnesium alloy extruded material undergoes warm plastic deformation; the strain range of the warm plastic deformation is 0.5%-6%. This method can use residual temperature to carry out online straightening and strengthening of magnesium alloy extruded materials. On the one hand, it can ensure the continuous production of magnesium alloy extruded products on a shorter production line, thereby saving process steps, improving production efficiency, and reducing The cost and energy consumption of the magnesium extrusion process, on the other hand, is also conducive to improving the high precision of the produced magnesium alloy extrusion.
Description
technical field [0001] The present invention relates to a magnesium alloy method, in particular to a method of magnesium alloy extrusion material. Background technique [0002] The magnesium-aluminum alloy extruded material in the light alloy has higher strength, plasticity and corrosion resistance than the as-cast state, and the light alloy extrusion process can realize one-time extrusion molding, with high production efficiency and great product flexibility. , it can produce products with complex cross-sectional shapes, and the lightweight effect is obvious. [0003] In addition, magnesium alloys have a low density (density of 1.8 g / cm 3 ), high specific strength and specific stiffness, and some excellent physical properties (such as thermal conductivity, electromagnetic shielding performance, damping and shock absorption performance, and response characteristics to the high-frequency range of sound), therefore, it is widely used in transportation industries such as autom...
