The Al-Si-based alloy is widely used, with more than 85% of the cast aluminum alloy, alloy smelting and formulation process is a critical factor in relationships. Among them, the silicon element is added to the crystalline silicon, which often requires an induction furnace and other equipment, and there is a problem such as crystalline silicon floating and oxidation.
In response to this problem, Shandong University has developed a fine alternating Al-50Si intermediate alloy (fine Al-50Si), which can be used to add silicon elements in the thermal stove, saving time saving.
Implementation Effect
Figure 10-1 Crystal Al-50Si products and their microstructure Figure 10-2 formulated Al-18Si-Cu-Ni-Mg alloy with fine al-50Si
As shown in Fig. 10-1, it is a fine-50 Si product and its micro-tissue, and the initial crystal silicon in the alloy is small, controlled below 70 μm. Add the fine crystal Al-50Si to the near eutectic Al-Si alloy, and add anti-Si \"poisoned \" AlTIC-B crystal alloy obtained by Al-18Si-Cu-Ni-Mg alloy, its primary crystal Si The average grain size is about 35 μm, the distribution is uniform, and the substantially no agglomeration is phenomenon, and the α-Al dendritic crystal is small, see Fig. 10-2.
Product advantages
Apply easy to use high energy consumption equipment such as induction furnace.
Fast dissolution, saving time saving.
The alloy prepared, its element content is accurate.
According to customer needs, other alloy elements such as Cu, Mg, Ni, etc. are added thereto.
Product specifications
The fine crystal Al-50Si is primarily a spindle specification.
Application field
Suitable for adding silicon elements in silicon-containing aluminum alloy melting.
