Study on Simulation of Mold Filling and Solidification Characteristics of Hypereutectic High-Chromium Cast Iron by Lost Foam Suspension Casting

Abstract

In this paper, the finite element software ProCAST version 14.5 was used to simulate the temperature field, flow field and defect prediction in the filling and solidification process of hypereutectic high-chromium cast iron. The effects of pouring temperature, negative pressure and the amount of suspension agent added during the technological process were explored. The optimum process parameters were presented. It was found that the suspension agent has a certain hindrance to the filling process, but the filling process remains stable. In the solidification stage, 89.4% of the suspension agent melted, resulting in a relative supercooling degree of 50 °C, which had a certain chilling effect and improved the solidification rate.

Numerical Simulation of Lost-Foam Casting for Key Components of A356 Aluminum Alloy in New Energy Vehicles

“…As a crucial analytical method, numerical simulation comprises various steps, including geometric modeling, flow simulation, heat transfer analysis, solidification analysis, and optimization design. Through multiple iterations of numerical simulation for process optimization, it not only visualizes the otherwise invisible behaviors of melt during casting but also maximizes the presentation of intricate details of the melt [17,18].…”
