本文讨论转炉等盛液回转体的重量、重心及其绕垂直于对称面某轴转动时的倾动力矩与转动惯量的计算。对常见的回转体,推导和归纳出了简单统一的计算公式,为设计者进行手算或电算提供了方便。 This article discusses the calculation of the weight, the center of gravity, and the moment of inertia and moment of inertia of a rotary converter such as a converter when it is rotated about an axis perpendicular to the plane of symmetry. For the common revolving body, a simple and unified calculation formula is deduced and summarized, which provides convenience for designers to do manual calculation or calculation.
