摘要: 基于抚顺特殊钢股份有限公司镍基合金生产平台,研究了“30 t非真空感应炉-炉外精炼-电渣重熔”工艺代替传统高成本工艺冶炼高钼含量镍基合金的可行性,并结合生产实际分析了生产效率和成本优势。结果表明,采用30 t非真空感应炉熔炼钢水,VOD吹氧脱碳后抽真空至67 Pa以下脱气冶炼工艺方案,成功实现了高钼含量镍基合金N06625、N10276产品的冶炼。电渣后的钢锭生产为204 mm锻材产品,化学成分、非金属夹杂物均满足行业标准要求,进一步提高了高钼镍基合金的生产保障及成本控制能力。

Abstract:  Based on the nickel-base alloy production platform of Fushun Special Steel Co., LTD., this paper studies the feasibility of "30 t non-vacuum induction furnace-external furnace refining-electroslag remelting" process instead of the traditional high cost process to smelt nickel-base alloys with high molybdenum content, and analyzes the production efficiency and cost advantages combined with the production practice. The results show that by degassassing smelting process scheme with 30 t non-vacuum induction furnace was used to melt molten steel , VOD blowing oxygen and decarbonized after vacuum to below 67 Pa, and the smelting of nickel-base alloy N06625 and N10276 products with high molybdenum content was successfully realized.The steel ingot produced after electroslag is 204 mm forging products, the chemical composition and non-metallic inclusions meet the industry standard requirements, and further improve the production guarantee and cost control ability of high molybdenum nickel-base alloy.
