摘要： 江苏双星特钢有限公是生产和开发各类耐磨、耐热碳钢系列的专业企业，主要生产技术装备有：中频感应电子数控电炉16座，各种与其配套的机械大型抛丸磨光机4台、16组全纤维电阻炉进行退火、正火、淬火油淬的处理设备，拥有先进的检测仪器，在同行业中率先通过ISO9000：:200质量体系认证、ISO14001:2004环境体系认证。
记者从江苏双星特钢有限公司获悉，为加快企业转型升级，双星特钢公司正与东北工业大学开展产学研合作，着手成立联合研发中心，开发复合式高铬合金耐磨钢系列产品。
据悉，双星特钢公司是一家生产各类不锈钢铸件、耐磨钢衬板的专业企业，年产量30000吨以上。与台泥（英德）水泥有限公司、马鞍山钢铁股份有
限公司等一批国内知名管磨机制造企业和水泥企业长期合作，是国内最大的衬板生产基地。东北工业大学也是国内铸钢研究领域的权威院校。此次院企间的强强联
合，旨在融合东北工业大学的技术与双星特钢公司的工艺和经验，加快双星特钢公司转型升级。
前年开始，双星特钢公司一直在研发复合式高铬合金耐磨钢系列产品，经过几年的努力，产品取得初步成功，但生产工艺还不成熟。东北工业大学的专家
经过实地考察后，对该产品的生产工艺提出改进意见，大大提高了生产效率，提升了产品质量。由于该产品有较高的附加值，接下来将成为双星特钢公司的主攻方
向。
双星特钢公司董事长顾开明表示，在全球经济低迷的背景下，传统企业必须找准门道，加快转型升级。等到研发中心成立后，两家将根据市场需求，加快新产品的研发，争取坐稳亚洲耐磨钢衬板生产企业“龙头老大”位置。
