Abstract

The invention discloses a production process of a non-vacuum downwards-drawing continuous casting copper-iron alloy slab ingot. The production process mainly comprises the following steps of burdening, charging, smelting, refining degassing, pouring, casting and ingot casting, wherein the copper-iron alloy slab ingot is successfully prepared by using an electrolytic copper plate and a CuFe50 master alloy as smelting raw materials through a non-vacuum downwards-drawing continuous casting process, and compared with a traditional vacuum casting process, the equipment requirement is low; inert gasprotection is adopted in the casting process, appropriate measures such as iron content are adjusted, and the alloy composition and the oxygen content are effectively controlled; the process has theadvantages of being stable in process, simple and convenient to operate, low in casting production cost and capable of realizing industrial production of the copper-iron alloy slab ingot.

Description

technical field [0001] The invention relates to the technical field of metal smelting, in particular to a production process for non-vacuum down-drawing continuous casting copper-iron alloy slabs. Background technique [0002] As high-strength and high-conductivity copper-iron 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-iron alloys. Copper-iron alloys exhibit 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 can be used in various industrial fields , has unsurpassed competitiveness and market prospects. [0003] However, judging from the copper-iron phase diagram, the two are almost completely immiscible a...
