sand casting

In order to verify the feasibility of casting process, the sample of open axle housing was trial produced according to […]

After adding riser and chill to the gating system, mesh division, casting parameters setting and pouring process simulation calculation are

The cold iron is directly attached to the area where the riser is not suitable. Because of the chilling effect

The ratio of the volume of the axle housing divided by the heat transfer surface area is called the solidification

Simulation and analysis of temperature field in closed gating system of axle housing The simulation of temperature field is shown

During pouring, under the action of gravity, the molten metal first enters the cavity through the sprue, enters the runner

Figures (a) and (b) show the flow of the liquid metal in the bridge shell when the metal liquid fills

Figure (a) is the real-time screenshot of the molten metal just filling the runner at the beginning of pouring, and

In order to predict and confirm the location, size and range of shrinkage defects in the pouring and feeding system

Setting of sand mold material parameters When sodium silicate molding sand is used in production, it can be replaced by

During the solidification of hot metal, the liquid and solid state of most metals exist together most of the time.

Generally, the thermal conductivity of metal is related to the temperature and chemical composition of molten steel, which is generally

The numerical model of axle housing is established by Creo software and saved in. STP format. The STP file is
