摘 要:铅的高比热容和较低熔点使其在热处理领域获得广泛的应用,随着对环保和健康问题的重视,铅淬火技术的应用也存在一定的产业政策限制,但在钢丝生产领域并未受到禁止,仍是国内外常用的钢丝热处理技术之一。中国的铅尘、血铅限值标准比西方国家高,允许值较低,主要差距在于控制技术和管理措施,在使用中要遵守相关的职业健康标准要求,重视覆盖技术的应用和日常管理。替代技术的主要发展方向是特定水溶液淬火、喷雾冷却及盐浴淬火,随着新技术的应用,铅淬火在钢丝生产中的使用比例将逐步减少。Lead is widely used in heat treatment field because of its high specific heat and lower melting point.The application of patenting has been limited in some industry policy with the increased importance on environmental protection and health problem,but was not forbidden by steel wire production field and still be one of the favorite steel wire heat treatments at home and abroad.China lead dust and blood lead limiting value standard are higher than western country,the permissible value is lower.The main gap is technical control and management measure.Relevant professional health standard requirement should be abided,covering technology application and daily management should be emphasized.Alternative technology's main development direction is specified water quenching,mist cooling,and salt-bath quenching.With the development of new technology,patenting application rate in steel wire production will decrease steadily.
