沈阳铸造研究所特钢技术产业部承担着我国耐热、耐磨、耐蚀特种铸钢材料、铸造工艺CAD、AOD精炼技术与设备的研究与开发任务。特别是在水电站水轮机过流部件用特种铸钢系列的材质、工艺和热处理研究方面取得了多项重大成果,由他们研究开发的OCrl3Ni4Mo和OCrl6Ni5Mo等电站用不锈钢系列材料已成为我国水轮机制造业采用的主体钢种,最新研制成功的电站用高屈强比不锈钢已达到国际先进水平。
该产业部目前有3000M2中试生产基地,装备有2吨一拖二串联逆变中频感应电炉和从美国联碳公司引进的AOD钢水精炼装置和现代化的炉前分析设备,具备生产高纯净钢的手段和条件。多年来,已为三峡等几十家国内外大型水电站,为多家水电站提供了多项先进制造技术和几千吨的优质铸件,研究成果先后获得国家技术进步特等奖等多项奖励。
