Manufacturing method of non-magnetic alloy

Abstract

The invention discloses a manufacturing method of a non-magnetic alloy. The manufacturing method comprises the following technological steps that a, an alloy mixture and anhydrous alcohol are poured into a ball grinding mill to be subjected to ball-milling treatment, and the alloy mixture is composed of tungsten carbide, metal nickel powder, tantalum carbide powder, metal titanium powder, metal molybdenum powder and metal aluminum powder; b, one-time screen filtering treatment is conducted; c, drying treatment is conducted; d, an alcohol mixture which is subjected to drying treatment is pouredinto a mixing machine, and a paraffin rubber gasoline solution is added into the mixing machine; e, a mixture formed by the alcohol mixture and the paraffin rubber gasoline solution which are mixed is poured into a pressing mould, and the mixture is pressed to form an alloy blank by means of an oil press; f, demoulding and blank taking are conducted; g, the alloy blank is subjected to drying treatment through an electric furnace; h, the alloy blank is installed into a graphite boat; i, alloy blank sintering is conducted; j, cooling is conducted; and k, cleaning is conducted. According to themanufacturing method, through the technological step design, a non-magnetic alloy part can be effectively produced and prepared, and the technological steps are reasonable, and good in stability and reliability.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a method for manufacturing a non-magnetic alloy. Background technique [0002] Non-magnetic alloys refer to hard alloy materials with no or weak magnetic properties. Since the forming mold for producing magnetic materials requires the use of non-magnetic materials, non-magnetic steel has been used in the past. The mold performance is poor, the hardness is low, and the service life is short. After a period of use, the inner wall of the mold is severely roughened and deformed, which affects the magnetic properties. The dimensional accuracy and surface quality of the material. Nowadays, non-magnetic hard alloys are used to replace non-magnetic steel with its excellent performance, which can double the work efficiency. [0003] For non-magnetic alloys, how to effectively produce and prepare non-magnetic alloy parts is particularly important. Contents of the invention [0004] The...
