武汉钢铁(集团)公司所属的武钢铁路工程器材厂生产的“钢禾牌”混合稀土金属丝于1998年11月24日通过了湖北省经济贸易委员会组织的新产品鉴定。由北京科技大学、北京钢铁研究总院、中国金属学会炼钢学会、湖北省稀土办等单位的专家组成的鉴定委员会经过认真审议,一致认为:该厂生产的混合金属丝生产工艺先进,在重熔、挤压、焊接等工艺技术上较现行工艺有明显改进,经查新检索有创新性;经检测,钢禾牌混合金属丝的产品质量各项指标均达到 YB/T010—92标准。其中抗拉强度、弯曲次数优于标准;该产品的质量达到国内先进水平,Φ2.0丝填补了国内空白。混合稀土金属丝作为炼钢添加剂,可以改善钢材的横向韧性、抗层状撕
Wuhan Iron and Steel (Group) Co., Ltd. Wugang Railway Engineering Equipment Factory production of “Steel Wo” mixed rare earth wire on November 24, 1998 adopted by the Hubei Provincial Economic and Trade Commission organized a new product identification. The accreditation committee composed of experts from Beijing University of Science and Technology, Beijing Iron and Steel Research Institute, China Metals Society Steelmaking Society, Hubei Rare Earth Office and other units after careful consideration, agreed that: the production of mixed metal wire factory advanced production technology, heavy Melting, extrusion, welding and other technology significantly improved than the current technology, the search has a new search innovative; After testing, steel Wo brand mixed wire quality indicators have reached YB / T010-92 standards. Among them, the tensile strength and bending times are better than the standard; the quality of the product has reached the advanced domestic level, Φ2.0 wire has filled the domestic blank. Mixed rare earth wire as a steelmaking additive, can improve the transverse toughness of steel, anti-layered tear
