Most of the magnesium materials are produced by extrusion process, and the products include tubes, rods, and shapes, and the extrusion is carried out at a certain temperature. The magnesium alloy extrusion process and equipment are equivalent to those for the production of aluminum alloy extrusions.The typical extrusion process of magnesium alloy: heating ingot→primary extrusion→cutting intermediate billet→heating→secondary extrusion→artificial aging→stretch straightening→cutting head and tail and taking samples→roller straightening→manual Straightening→inspection→cutting and printing→oxidation coloring→finished product inspection→packaging→warehousing.
Hot extrusion is the primary plastic deformation processing technology for deformed magnesium alloys. Like the extrusion of deformed aluminum alloys, magnesium alloy extrusions can be extruded forward or backward, and can be produced by single-acting extrusion machines. It can also be produced with a double-action extrusion machine, either a horizontal extrusion machine or a vertical extrusion machine. In short, any equipment used for extrusion-aluminum alloy semi-finished products can be used to produce magnesium alloy materials, but the process parameters are different, and the supporting equipment and finishing equipment are different.
The forward extrusion method is mainly used in the production of magnesium alloy extrusion materials, and the reverse extrusion method is rarely used. If you have time, you may use the combined extrusion method, that is, the reverse extrusion method is used at the initial stage of extrusion to eliminate the friction between the extrusion cylinder and the ingot during forward extrusion, and then immediately turn to forward extrusion. However, this combined process is rarely used.
