Abstract

The invention relates to a method for smelting a high-purity nickel-molybdenum alloy. The high-purity nickel-molybdenum alloy comprises the following main components in percentage by weight: 8-30wt% of Ni, 10-30wt% of Mo, no more than 0.5wt% of Si, no more than 0.5wt% of C, no more than 0.1wt% of Cu, no more than 0.03wt% of P, no more than 0.03wt% of S and the balance of iron. According to the invention, the advantageous resource Mo in China is added in the known formula, and simultaneously, the process is improved to reduce the S (sulfur) and P (phosphorus) content, thereby ensuring that the high-purity nickel-molybdenum alloy completely achieves various performance indices of like products at home and abroad.

Description

technical field [0001] The invention relates to the application field of alloy steel, especially the application of special materials for engines and pistons on automobiles and motorcycles. Background technique [0002] The performance of the engine and piston materials on automobiles and motorcycles is directly related to the performance and safety of automobiles and motorcycles, as well as the stability, service life and work efficiency of the engines. The alternation of rapid cooling and rapid heating of automobiles has caused a large contrast in the alternating stress suffered by the engine. Therefore, higher requirements are placed on the creep strength, electrical conductivity, safety factor, and corrosion resistance of spark plug materials. The performance of the material is related to the overall performance of the engine and the service life of the vehicle. Because of this, countries all over the world have paid more attention to the development of special material...
