Compared with conventional casting magnesium alloys,
semi-continuous casting magnesium alloys are finer in the
organization, more uniform on the ingredients, and more compact
inside with higher strength and elongation.
1. By pipetting and secondary refining, the Mg alloys have high
purity and low impurity. The magnesium liquid pouring directly from
the heat holding furnace crystallize rapidly to improve the
compactness of internal microstructure of the Mg rods. The internal
crystal are more compact , and the physical performance is greatly
enhanced compared to conventional casting products.
2. The flux slag content of finished products tends to zero. Using
the emerging insert gas protective devices, the flux slag content
are greatly reduced and product quality is improved. In traditional
process, the smelting process is completely exposed to the air, and
the flame is retardant only by flux and other flame retardant
materials.
3. Smooth surface. Clean. No porosity, shrinkage or slag.
4. Flexible length. The existing maximum diameter is 600mm. It can
be skinned and cut according to customers' requirements. In
addition, other products with different specifications can be
produced to meet customers needs. We can also produce various
specifications of Mg alloy flat bars by semi-continuous casting.
