Abstract

The mathematical apparatus of a model developed to describe the distribution of dispersed particles during centrifugal casting is described. The distribution of dispersed tungsten carbide particles in grade 20 steel during centrifugal casting on a centrifugal casting machine with a vertical axis of rotation is investigated. As a result of numerical simulation, the presence of a gradient distribution of dispersed particles is found and the limiting concentration of particles (0.008–0.013 g/cm³) is determined. The distribution of dispersed particles over the solidifying workpiece volume to be simulated is obtained.

垂直旋转轴离心铸造过程中硬化分散颗粒分布的数值模拟

摘要

描述了为描述离心铸造过程中分散颗粒的分布而开发的模型的数学装置。研究了在具有垂直旋转轴的离心铸造机上离心铸造过程中20级钢中分散的碳化钨颗粒的分布。作为数值模拟的结果，发现了分散颗粒的梯度分布，并确定了颗粒的极限浓度（0.008-0.013 g/cm ³）。获得了待模拟的凝固工件体积上分散颗粒的分布。
