COPPER-IRON ALLOY SLAB NON-VACUUM DOWN-DRAWING CONTINUOUS CASTING PRODUCTION PROCESS

WIPO Patent Application WO/2021/018203

A1

A copper-iron alloy slab non-vacuum down-drawing continuous casting production process, the main steps comprising: ingredient provision, furnace loading, smelting, refining and degassing, pouring, casting, and ingot cooling, electrolytic copper plate and a CuFe50 master alloy being used as the raw materials for smelting, copper-iron alloy slabs being prepared by means of successfully undergoing a non-vacuum down-drawing continuous casting process, and the equipment requirements being lower than traditional vacuum casting processes; appropriate measures such as inert gas protection and iron content adjustment are employed during the casting process, effectively controlling the alloy composition and oxygen content; the present invention has the advantages of the process being stable, the operations being simple, and the casting production being low cost, and can implement industrial production of iron-copper alloy slabs.
