高品质Inconel 600焊丝(ERNiCr-3)坯料熔炼工艺研究

Study on the smelting process of high quality Inconel 600 welding wire(ERNiCr-3)

Inconel 600焊丝主要用于熔化极气体保护焊、钨极惰性气体保护焊和埋弧焊等方法焊接Inconel 600/601/690合金,此焊丝形成的金属焊缝具有较高的强度和较好的耐蚀性,在高温下具有较好的抗氧化能力和较高的蠕变破裂强度。本文从真空感应熔炼、真空电弧熔炼及电渣熔炼三种熔炼方法入手,在原有生产工艺上探索、改进高品质Inconel 600焊丝(ERNi Cr-3)熔炼方法。

Inconel 600 wire is mainly used for MIG welding,TIG welding and submerged arc welding of Inconel 600/601/690 alloys. The welding joints by using the Inconel 600 wires have a high strength and good corrosion resistance and good oxidation resistance and high creep rupture strength at high temperature. The exploration and improvement of the smelting method of high quality Inconel 600 welding wire( ERNiCr-3) which is produced by vacuum induction melting,vacuum arc melting and electroslag smelting are introduced in the paper.
