Title:
ELECTRIC MELTING METHOD FOR FORMING NUCLEAR POWER PLANT EVAPORATOR CYLINDER
Document Type and Number:
WIPO Patent Application WO/2016/070777
Kind Code:
A1
Abstract:
An electric melting method for forming a nuclear power plant evaporator cylinder: an electric melting head (6) and a substrate (2) respectively are connected to either electrode of a power source (12), when forming, a raw material wire (1) is fed to a surface of the substrate (2) via a wire feeder mechanism (5) and the electric melting head (6), under the protection of a stack of a granular auxiliary material (3), the raw material wire (1) is molten under the effects of three heat sources, namely electric arc heat, resistance heat, and electroslag heat, a partly molten pool (11) is formed on the surface of the substrate (2), conveyance of the raw material wire (1) and the auxiliary material (3) is continued, a computer is employed to control relative movements of the electric melting head (6) and of the substrate (2) on the basis of layer slicing data of a forming component, rapid cooling and layer-by-layer solidification and deposition of the molten pool (11) on the substrate is implemented, and finally, the nuclear power plant evaporator cylinder is formed. The method is highly efficient and inexpensive. The nuclear power plant evaporator cylinder formed is provided with great mechanical properties.
