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 tra-ditional high cost process to smelt nickel-base alloys with high molybdenum content,and analyzes the production effi-ciency 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 af-ter vacuum to below 67 Pa,and the smelting of nickel-base alloy N06625 and N10276 products with high molybdenum con-tent was successfully realized.The steel ingot produced after electroslag is 204 mm forging products,the chemical composi-tion 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.
