摘要

针对大、中型离心机铸型在高速旋转及高温金属液作用的工况

分析了金属筒套断面上由金属筒套自身质量及金属液产生的离心力组成的总拉应力。通过建立因金属筒套自身质量在离心力作用下对金属筒套断面拉应力和因金属液在离心力作用下对金属筒套断面的拉应力的计算方法

旨在为离心机铸型金属筒套破裂的安全事故定量分析提供参考。

Abstract

Total drawing stress for cross section of metal sleeve was analyzed

which comes from self mass of metal sleeve and centrifugal force of molten metal

aiming at the operating condition of large or middle centrifugal machine in condition of high speed rotating and high temperature molten metal.The new calculating equation was presented for reference to quantitatively analyzing crack accident of the metal sleeve in centrifugal machine mould.
