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。 Aiming at the working conditions of large and medium-sized centrifuge molds rotating at high speed and high temperature molten metal, the total tensile stress composed of the mass of the metal tube and the centrifugal force caused by the molten metal on the metal tube section was analyzed. Through the establishment of its own quality due to the metal tube sleeve under centrifugal force on the tensile stress of the metal tube sleeve section and the liquid metal under centrifugal force on the metal sleeve section of the tensile stress calculation method designed to centrifuge mold metal sleeve rupture The quantitative analysis of safety accidents provide a reference.
