Problems solved by technology

[0004] At present, the methods of producing CuFe alloy at home and abroad include: mechanical alloying method, gas atomization method, falling tube method, electromagnetic levitation melting method and vacuum arc melting method, etc. Some of these methods are relatively expensive, and some cannot achieve mass production. The existing vacuum induction smelting method needs to add rare earth elements. The present invention aims at the deficiencies in the prior art and provides a preparation method using vacuum induction smelting

Abstract

The invention discloses a preparation method for a CuFe mother alloy material by adopting vacuum induction melting. The preparation method for the CuFe mother alloy material by adopting vacuum induction melting comprises the steps of (1) weighing Cu and Fe raw materials according to the proportion, loading in a crucible, placing in a vacuum melting furnace, closing a furnace cover and a deflationvalve, and cleaning an observation window; (2) starting a mechanical pump and a low-vacuum baffle valve: when the vacuum pressure P in the vacuum melting furnace is less than or equal to 0.08MPa, starting the roots pump; when vacuumizing until the P is less than or equal to 4Pa, rising the power of the vacuum melting furnace to 25KW, preserving heat for 8min, rising the power of the vacuum meltingfurnace to 45KW, preserving heat for 8min, rising the power of the vacuum melting furnace to 65KW, and reducing the power to 20KW after raw materials in the crucible are uniform; and filling argon into a furnace body, closing an argon filling valve when the pressure in the furnace rises to 0.08Mpa, rising the power to 70KW, and refining for 2min; and (3) reducing the power of the vacuum melting furnace to 40KW, keeping for 0.5min, starting to cast in a casting mould, cooling for 60min after finishing casting, and discharging.

Description

technical field [0001] The invention belongs to the technical field of new material preparation, and in particular relates to a preparation method of CuFe master alloy material by vacuum induction melting.
