Spin-casting device and spin-casting centrifugal disk

Abstract

The invention relates to a spin-casting device and a spin-casting centrifugal disk. The spin-casting device comprises a fixed frame, the fixed frame is provided with a crucible for holding metal raw materials in a molten state, a centrifugal disk body is arranged under the crucible, and the centrifugal disk body rotates at a high speed to atomize and throw out the metal raw materials and the metalraw materials are attached to the inner wall of a cylinder-shaped die; and the centrifugal disk body is further provided with a cooling medium flow channel, and a cooling medium can cool the disk surface of a disk body. The cooling medium is led to the cooling medium flow channel of the centrifugal disk body in the centrifugal disk body to cool the disk surface, and when the metal raw materials are poured downwards onto the centrifugal disk body by a flow guide pipe under the crucible, heat exchange is carried out between the metal raw materials and the disk surface, so that heat of the metalraw materials is reduced, cooling can be carried out faster; and in the process of throwing out, the metal raw materials can form semi-solid droplets smoothly, and the phenomenon of sample collapse due to the fact that the atomized particles still keep in a liquid state when colliding with the inner wall of the cylinder-shaped die and the droplets on the die fuse and flow together is avoided, sothat a produced metal hollow ingot has a flat surface, uniform thickness and small grain size.

Description

technical field

[0001] The invention belongs to the technical field of processing and forming of advanced metal materials, and in particular relates to a throw casting device and a throw casting centrifugal disc. Background technique

[0002] In recent years, with the development of my country's petroleum, chemical, nuclear power, thermal power and other industries, the efficiency of energy development and utilization has become higher and higher, and the volume of energy equipment has also become larger and larger. The performance and size of hollow forgings in energy equipment The requirements are also constantly increasing. For example, "large cylindrical parts" such as nuclear reactor pressure vessels and petrochemical hydrogenation reactors, "large-diameter thick-walled alloy steel pipes" such as "large-diameter thick-walled alloy steel pipes" such as nuclear power main pipes and ultra-supercritical thermal power main steam pipes, thermal power turbine generator guard ri...
