Product type: semi-continuous magnesium alloy bar

　　Application: suitable for magnesium and magnesium alloy processing products, plate, strip, tube, bar, profile and wire products and alloy ingot and slab used.

　　Implementation standard:

　　GB/T5153-2003

　　ASTM/B107/B107M-92

　　Conventional product material: AZ31B, AZ31D, AZ61A, AZ80A, MG-Mn, etc.

　　Product features: ASTM·B107/B107M-92 semi-continuous draw-cast magnesium alloy compared with cast magnesium alloy, semi-continuous draw-cast magnesium alloy has finer structure, more uniform composition and denser interior, and has advantages of high strength and high elongation than cast magnesium alloy.

　　(1) Through pipetting and secondary scouring, the magnesium liquid is of high purity and less impurities. It is poured directly from the heating furnace to rapidly crystallize the magnesium liquid and improve the density of the internal tissue of the magnesium bar. The inner crystallization is more reasonable and compact, and the physical properties are greatly improved than the traditional casting products.

　　(2) molding products tend to have more zero flux slag content, namely half continuous use in the magnesium alloy smelting industry emerging inert gas protection device, changed the traditional craft completely exposed to the air in the process of smelting, only use the flame retardant materials, such as flux is made of the least flame retardant magnesium forming method, make the flux slag content is greatly reduced, improve product quality.

　?、?The surface is smooth and clean, without pores, shrinkage holes and slag inclusion.

　　(4) The length is flexible and optional, the existing specifications are φ 93, φ 112, φ 170, φ 212, φ 217, φ 230, can be cut according to user requirements, in addition, can also produce other different specifications of products to meet customer needs.

　　⑤ It can also be semi-continuous drawcasting of various specifications of magnesium alloy flat bar (such as: thickness 200mm×500mm).
