In the early application of squeeze casting technology, the melt transportation was basically manual transportation and mold filling. The labor intensity of workers was high, and the production efficiency was low. During the mold filling process, the high-temperature molten metal was prone to oxidation, which affected the performance of...
Al-Si alloy has good casting properties. After modification, inoculation and heat treatment, it has good comprehensive mechanical properties, corrosion resistance and good cutting performance. It is the most famous and most widely used alloy among cast aluminum alloys. It is widely used in military, industrial, railway transportation and other...
Casting process refers to the process of pouring high-temperature liquid metal into the mold to obtain a certain shape of castings after cooling and solidification. The spiral bevel gear studied belongs to small thin-walled precision steel castings. The casting material 20CrMoH belongs to low alloy steel, which has high...
Pressure casting Pressure casting refers to the process of injecting molten metal into the mold under the action of other external forces (excluding gravity). Pressure casting in a broad sense includes pressure casting, vacuum casting, low-pressure casting, centrifugal casting, etc; Narrow sense of pressure casting refers to the metal...
The so-called pressure casting mainly refers to the aluminum alloy wheel hub casting obtained by filling the liquid metal into the mold cavity at a high speed under the action of high pressure and condensation through the action of pressure. The aluminum alloy wheel hub casting produced by pressure...
Casting mainly includes back pressure casting and low pressure casting. The pressure of low-pressure casting is relatively low, so it is called “low-pressure casting”. Low pressure casting mainly uses the pressure of gas, adds liquid metal into the mold, and condenses and forms under the action of pressure. Backpressure...
The structure of the flywheel housing is relatively complex and belongs to a typical thin-walled shell structure. Due to the need to install a variable displacement pump on the flywheel housing, one side of the flywheel housing is suspended outside, which has a great impact on the structural stiffness...
The flywheel housing is an extremely important power output component in the vehicle power system, and it is also a vital component to bear the load. On the small road sweeper, the flywheel housing is installed between the Ningmou frame and the engine, which directly bears the overturning torque...
The low-pressure casting simulation model of flywheel housing is established by ProCAST. The simplified three-dimensional digital model of the die is imported into ProCAST in. XT format to establish the curved surface and close the casting cavity. Generate two entities of die and low-pressure casting blank, and set the...
From the point of view of thermodynamics, primary carbides should only exist in hypereutectic alloy. But in fact, it can also be observed in the near eutectic alloy 2 #. According to the previous research results, this may be due to the left shift of eutectic point caused by...
