squeeze casting

In the middle part of the workpiece, take a test bar with a diameter of 6 mm according to the

By analyzing the metallographic structure of the parts successfully manufactured by rheo squeeze casting, it is found that liquid phase

Figure 1 shows the metallographic structure of different parts of 7075 alloy wheel extrusion casting. It can be seen from

The quality of wheel shaped rheo squeeze casting parts is closely related to the extrusion filling speed, pouring temperature, mold

Under the condition that the pouring temperature is 630 ℃ and the extrusion filling speed is 0.4m/s, the mold temperature

Under the condition of keeping the die temperature at 160 ℃ and high extrusion speed of 0.4m/s, the pouring temperature

According to the specific parameters of semi-solid vertical squeeze casting machine, combined with the laboratory test data, the process parameters

The process of numerical simulation of AnyCasting software includes: firstly, the pre-processing is carried out by any pre, including the

Based on the theory of numerical simulation and fluid mechanics, the equations of solidification heat transfer are established Momentum conservation

The semi-solid 7075 alloy melt is different from the traditional liquid alloy ① Semi solid alloy melt has good fluidity,

Rheo squeeze casting is to squeeze the semi-solid alloy melt from the bottom into the cavity which has been closed

The structure design of squeeze casting die requires simple structure, reasonable process, easy manufacturing and quality assurance. This paper mainly

According to the needs of design and development of semi-solid vertical squeeze casting machine, a wheel like part (similar to

Figure 1 shows the microstructure of as cast rheo squeeze casting Mg – 0.43nd – XY – 0.08zn – 0.11zr
