Title:
ELECTRIC MELTING METHOD FOR FORMING NUCLEAR POWER PLANT VOLTAGE REGULATOR CYLINDER
Document Type and Number:
WIPO Patent Application WO/2016/070779
Kind Code:
A1
Abstract:
An electric melting method for forming a nuclear power plant voltage regulator cylinder: a high-energy heat source formed by combining electric arc heat, resistance heat, and electroslag heat is employed to melt a continuously conveyed raw material metal wire (1), which is solidified and deposited layer-by-layer on a substrate (2) to form a manufactured metal structure; an electric melting head (6) and a substrate (2) are connected to either electrode of a power source, when forming, the raw material metal wire (1) is fed to a surface of the substrate (2) via a conveyor mechanism (5) and the electric melting head (6), under the protection of a stack of a granular auxiliary material (3), an electric arc (9) is produced between the raw material wire (1) and the substrate (2) to partly melt the surfacing auxiliary material (3) to form a molten slag pool (8), an electric current flows through the raw material wire (1) and the molten auxiliary material slag pool (8) to form resistance heat and electroslag heat, the raw material wire (1) is molten under the effect of the high-energy heat source combining the electric arc heat, the resistance heat, the 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 on the substrate (2) is implemented, and finally, the voltage regulator cylinder is formed by layer-by-layer deposition.
