The company has developed a semi-solid forming visualization technology for automotive aluminum alloy wheels. The technology has developed a set of equipment which can objectively reproduce the semi-solid filling and solidification process of automotive aluminum alloy wheels, the device consists of a slurry preparation device, a quantitative crucible, a semi-solid slurry filling and solidification simulation device, and a video recorder. A certain amount of CARNAUBA WAX was added into the slurry melting box at the melting temperature of 80 ~ 85 °C. when the CARNAUBA WAX was paste, 30 ~ 50 μm organic particles were added, which accounted for 15 ~ 50% of the volume of the CARNAUBA wax. After stirring, the semi-solid slurry was formed A quantitative crucible was used to scoop the semi-solid slurry into the feeding hole of the semi-solid slurry filling and solidification simulation device, and a video recorder was opened to analyze the filling and solidification process of the slurry by slow release. The viscosity, fluidity and solidification state of the semi-solid slurry prepared by Carnauba wax and organic particles are very similar to that of the semi-solid slurry of aluminum alloy, which can provide valuable guidance for the development of automobile aluminum alloy wheel die and process.
