The scope of application: applicable to magnesium and magnesium
alloy products, plates, ribbons, tubes, rods, profiles and wire
products and its alloys used in ingot and slab.
Implementation of standards：
GB/T5153-2003
ASTMB107/B107M-92
Conventional materials：AZ31B, AZ31D, AZ61A, AZ80A, Mg-Mn Implementation of standards: ASTM B107/B107M-92 pull
semi-continuous casting of magnesium alloy and magnesium alloy
casting as compared to semi-continuous casting of magnesium alloy
in Latin America, organized on a more detailed, more uniform
composition, the internal is more dense than the magnesium alloy
casting with high-strength and high elongation and so on.
① transfer fluid through the secondary refining, high purity and
low impurities, magnesium liquid directly from the heated casting
holding furnace to the rapid crystallization of a magnesium rod to
raise the internal microstructure of the compact, dense internal
crystallization of a more rational, physical properties than the
traditional casting products has increased greatly.
② Forming products slag content in more flux tends to zero, that
is, semi-continuous use of the current magnesium alloy smelting
industry emerging inert gas protection equipment, has changed the
traditional process in the smelting process of fully exposed to the
air, can only rely on flux, such as flame-retardant molding
products made of magnesium were the most fire-retardant approach,
so that the content of the slag flux greatly reduced, improved
product quality.
③ the surface smooth, clean, non-porosity, shrinkage, slag.
④ arbitrary length of flexible, existing specifications 93, 112,
170, 212, 217, 230, according to user requirements skinned, cut
above the other, but also the production of other products with
different specifications to meet customer needs .
⑤ pull can also be semi-continuous casting of magnesium alloys of
various specifications for flat bars. (For example: thick
200mm500mm). | | | | | |
