Abstract

The invention provides a nickel alloy powder atomization manufacturing process. The nickel alloy powder atomization manufacturing process comprises the first step of smelting, wherein various raw materials meeting the requirement for the composition proportion of nickel alloy powder are added into a furnace to be smelted to be alloy liquid, and then the obtained alloy liquid is cooled through a cooler unit; the second step of atomization, wherein an atomization tower is used, and jet atomization is carried out on the alloy liquid obtained in the first step through a high pressure water pump system under the protection of nitrogen; the third step of filtering, wherein moisture of the nickel alloy powder obtained in the second step is removed through a pressure filter; the fourth step of drying, wherein the nickel alloy powder obtained in the third step is poured into a double-cone rotation vacuum drier to be dried; the fifth step of grading, wherein the nickel alloy powder obtained in the fourth step is graded through a double-layer eddy-vibrating screen, and a nickel alloy powder product of 160-300 meshes is separated out. The invention further provides equipment of the nickel alloy powder atomization manufacturing process. According to the technical scheme, nickel alloy powder particles meeting the GB5316-85 regulation can be produced, and the particles within the range of 160-300 meshes can reach above 70%.

Description

technical field [0001] The invention relates to the field of metal surface spraying, in particular to a nickel alloy powder atomization manufacturing process and equipment thereof. Background technique [0002] Nickel alloy powder is the main material for thermal spraying on metal surfaces in the machinery manufacturing industry, usually with a specification of 160-300 mesh. At present, domestic high-pressure water atomization nickel alloy powder production equipment is just in its infancy, and most of the production equipment is imported from the United States, the United Kingdom, and Germany. Due to the high price and low powder output, the development of my country's powder industry is restricted; some domestic imitation equipment is due to foreign technology. Strictly confidential, the production technology is not up to standard, the production process is relatively backward, and the shape uniformity and oxygen content of the produced powder are unstable. Domestically, t...
