Abstract

The invention relates to a cast bronze alloy material, in particular to a cast bronze alloy material for a nuclear turbine valve body. The alloy material comprises the following components in percent by weight: 0.5 to 1.5 percent of nickel plating silicon carbide, 15 to 17 percent of aluminum, 4 to 5.5 percent of iron, 0.5 to 1.5 percent of manganese, 0.5 to 1.2 percent of nickel, 0.2 to 0.7 percent of lanthanum or cerium, and the balance copper and inevitable impurities. The strength and the hardness of the alloy material can be realized without the need for further forging or heat treating alloy, the production cost is reduced, the production process is simplified, and the requirement on the material for the nuclear turbine valve body is met. The invention further relates to a preparation method of the cast bronze alloy material.

Description

technical field [0001] The invention relates to a bronze alloy material, in particular to a casting bronze alloy material for a valve body of a nuclear power steam turbine, and also relates to a preparation method of the bronze alloy material. Background technique [0002] Bronze materials are widely used due to their good ductility and forgeability. For example, they are forged into various valve blocks, wear-resistant pump blocks, and valve bodies, which are used in nuclear power steam turbines and other technical fields. However, with the rapid development of the nuclear power industry, the demand for bronze materials is increasing, and the performance requirements are also increasing. The traditional bronze material will produce various defects during the forging process, which is increasingly unable to meet the needs of high-standard alloy ingots for pumps and valves at home and abroad, and the forging process is complicated, costly, and long-hours. Therefore, the deve...
