Problems solved by technology

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. Dimensional accuracy and surface quality of materials

Embodiment Construction

[0029] The present invention will be described below in conjunction with specific embodiments.

[0030] A method for manufacturing a non-magnetic alloy, comprising the following process steps, specifically:

[0031] a. Accurately weigh tungsten carbide powder, metal nickel powder, tantalum carbide powder, metal titanium powder, metal molybdenum powder, and metal aluminum powder, and weigh the tungsten carbide powder, metal nickel powder, tantalum carbide powder, and metal titanium powder , metal molybdenum powder, and metal aluminum powder are poured into the ball mill. Tungsten carbide powder, metal nickel powder, tantalum carbide powder, metal titanium powder, metal molybdenum powder, and metal aluminum powder form an alloy mixture. The percentage of each material in the alloy mixture is The content is as follows: tungsten carbide powder 80.5%, metal nickel powder 15%, tantalum carbide powder 0.5%, metal titanium powder 2%, metal molybdenum powder 1%, metal aluminum powder 1...

Abstract

The invention discloses a method for manufacturing a non-magnetic alloy, which includes the following process steps: a. Pour the alloy mixture and absolute alcohol into a ball mill for ball milling treatment. The alloy mixture consists of tungsten carbide powder, metal nickel powder, Composed of tantalum carbide powder, metal titanium powder, metal molybdenum powder, and metal aluminum powder; b, primary screen filtration treatment; c, drying treatment; d, pour the dried alcohol mixture into the mixer, and pour it into the mixer Add paraffin rubber gasoline solution; e, pour the mixture formed by the mixed secondary filtered mixture and paraffin rubber gasoline solution into the pressing mold, and press and form the alloy blank by means of a hydraulic press; f, demoulding and taking; g , drying and processing the alloy blank by electric furnace; h, loading the alloy blank into a graphite boat; i, sintering the alloy blank; j, cooling; k, cleaning. Through the above design, the present invention can effectively produce and prepare non-magnetic alloy parts with reasonable process steps and good 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...
