Non-vacuum smelting and continuous casting of copper-iron alloys

Abstract

The invention discloses a technology for smelting and continuous casting of a copper-iron alloy in a non-vacuum manner. The technology comprises the following steps that firstly, burdening is conducted, according to weight percent, the percent content of the Fe element in raw materials is 5%-20%, and the percent content of the Cu element is 80%-95%; secondly, charging is conducted, the mixed raw materials are arranged in a furnace, and a covering agent, a CuFe mother alloy and an electrolytic copper plate are sequentially arranged in the smelting furnace; thirdly, smelting is conducted, temperature rise is conducted for melting, and in the temperature rise melting process, gas protection is conducted in a furnace opening of the smelting furnace; fourthly, gas removal and deoxidation are conducted, argon gas removal, pure titanium deoxidation and CuMg alloy deoxidation are sequentially conducted; and fifthly, continuous casting is conducted, a runner is subjected to gas protection in the pouring process, the casting speed of a casting machine is strictly controlled, and electromagnetic stirring is conducted. The technology is stable, operation is simple and convenient, the fusion casting production cost is low, and the prepared CuFe is free of the obvious segregation phenomenon.

Description

technical field [0001] The invention relates to the technical field of non-ferrous metal alloys, in particular to a non-vacuum melting and continuous casting process for copper-iron alloys. Background technique [0002] As high-strength and high-conductivity copper alloys are widely used in various industries, higher requirements are placed on the performance and manufacturing costs of such high-strength and high-conductivity copper alloys. Copper-iron alloys have the electrical conductivity, thermal conductivity, and ductility of copper at the same time. properties such as resistance, elasticity and iron's wear resistance, strength, hardness, magnetism and other properties, showing unique and superior characteristics, such as electromagnetic wave shielding, elasticity, conductivity, heat release, wear resistance, antibacterial properties etc., and copper-iron alloys can be processed into various physical forms such as rods, cables, plates, films, powders, tubes, etc., and c...

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
