摘　　要：研究了UNS N08825合金在非真空感应熔炼与采用含有TiO2渣系电渣重熔后合金元素,特别是钛元素的控制;分析了钛元素烧损的机理;结果表明非真空感应熔炼825合金时电极锭钛含量至少在1.0%,1.0~1.2%最佳,经过电渣后铸锭钛含量可控制在0.6~1.2%规格范围内。The control of alloying elements,especially titanium,of UNS N08825 alloy after non vacuum induction melting and electroslag remelting using a slag system containing TiO2 was studied;The mechanism of burning loss of titanium was analyzed;The results show that the titanium content in the electrode ingot during non vacuum induction melting of 825 alloy is at least 1.0%,and 1.0~1.2%is the best.After electroslag remelting,the titanium content in the ingot can be controlled within the specification range of 0.6~1.2%.
