Advantages
1.High hardness, wear resistance, light weight.
2.The biggest advantage is the price, the current market products are mainly aluminum wheels, there are relatively few uses other materials.
3.The cost is lower than the cast alloy wheels. The Strength to weight ratio is also better than that of the cast alloy wheel.
4. Hardness is 1.90 times than the original material (stainless steel)
5. Energy-saving, 35% lighter than the original material (stainless steel)
6. Repairing technology is maturing, and there are many domestic spare parts suppliers.
Benefits
In order to accelerate the development of new technology for future products, to explore new markets, and to rapidly expand the market share of enterprises, many brands are preferring aluminum alloy wheels, which have replaced cast iron wheels and are becoming more and more favored by consumers one step at a time.
Influence of improper design of wheel hub structure on wheel hub cracks
The improper size of the fillet is the most common cause of hot cracks in the hub, because the sharp corner of the hub will generate a lot of stress when it cools. In parts with small fillets, even if the feeding is good and no shrinkage cracks occur, thermal cracking will occur.
The sudden change of the hub section will lead to different cooling rates. Even if the feeding is good, large stress will be generated, which will cause cracks or cracks to appear after the hub is solidified.
Influence of unreasonable process parameters on wheel hub cracks
In low-pressure casting, the liquid in the riser solidifies due to too long pressure holding time or too long riser pipe, and bears a certain tensile force when the hub casting is ejected, resulting in cold cracking of the hub. Therefore, it is of great significance to design a reasonable pressure holding time and lifting system to reduce the cracking caused by the hub during ejection.
Influence of die temperature on hub cracks
The mold temperature of low pressure casting determines the solidification method of the alloy liquid, and directly affects the internal and surface conditions of the casting. It is one of the main reasons for many defects such as dimensional deviation and deformation of the casting. Die temperature varies with casting weight, die casting cycle, die casting temperature and die cooling method.
From the point of view of heat transfer, increasing the mold temperature can reduce the heat transfer intensity between the metal and the mold and prolong the flow time. Some studies have also shown that increasing the mold temperature can slightly reduce the interfacial tension between the molten metal and the mold. As the mold temperature increases, the filling time decreases slightly, that is, the filling capacity increases with the increase of the mold temperature.
Therefore, an appropriate increase in the mold temperature is conducive to reducing stress. If the mold temperature is too low, the casting will cool too quickly in the metal mold, and the solidification speed of each part of the casting will be different, which will cause uneven cooling of the casting in the mold, resulting in thermal stress and deformation result in thermal cracking and large residual stress and residual deformation on the finished casting. The higher mold temperature is not conducive to obtaining a fine crystal structure, and the liquid metal is easy to inhale and shrink, causing the casting to produce an increased chance of defects such as pores, shrinkage and shrinkage. To unify this contradiction, the mold temperature can be appropriately increased without casting defects.
