Method for preparing spherical nickel base alloy materials for manufacturing steel teeth

Abstract

The invention discloses a method for preparing spherical nickel base alloy materials for manufacturing steel teeth, which relates to the technical field of alloy material. The invention is characterized in that the nickel base alloy material comprises the following chemical compositions in percentage by weight: 10 to 15 percent of copper, 3 to 7 percent of chromium, 4 to 8 percent of tin, 2 to 5 percent of silicon, 0.1 to 0.5 percent of cobalt, 0.5 to 2 percent of boron, and the rest for nickel; and the method comprises the following steps: putting the chemical compositions above into a high-temperature crucible, and heating the chemical compositions in a high frequency or medium frequency furnace to melt the compositions; evenly mixing the obtained high-temperature melting liquid for 5 to 10 seconds; and pouring the high-temperature melting liquid subjected to even mixing into a cooling device to carry out centrifugal cooling treatment so as to form spherical particles (particle size: 5 to 8mm). The method is simple and the smelting process does not need to be carried out in a vacuum environment or an atmosphere protection environment by the method.

Description

technical field [0001] The invention relates to the technical field of alloy materials, in particular to a method for preparing a nickel-based alloy material mainly composed of metallic nickel, which is suitable for manufacturing steel teeth. Background technique [0002] Steel teeth are currently one of the most commonly used dentures, and the materials used to manufacture steel teeth are mainly nickel-based alloys. At present, the nickel-based alloys used to make steel teeth at home and abroad have various chemical compositions and great differences in appearance and shape, but there are various problems. These problems are mainly manifested in: 1) complex chemical composition, poor uniformity, inconvenient production; 2) brittle quality, easy to break castings; 3) dull luster or poor light perception; 4) quality during repeated use, that is, secondary melting Become brittle, or darken the luster, or produce defects, etc.; 5) It is difficult to melt the massive and cylind...
