摘要
介绍了高速钢的概念、成分及其分类。中国高速钢生产从1918年开始经历了萌芽阶段、仿制阶段、创制阶段、替代进口、专业化和国际化6个阶段,现已成为世界高速钢大国。对比近5年高速钢品种变化,显现出热轧棒材数量减少,光亮材数量增加;锻材和扁钢数量均减少;锻坯、锻件、工具毛坯等增加的趋势。国产高速钢基本满足国内市场需求,并有大量出口和少量进口,总体看高速钢出口增量超过进口增量,高速钢产能过剩,市场需求减少。建议:获得全球视野,提升国际竞争力;做专做强,争创标杆;树立卓越思维,实现管理精细化;提高服务质量,拓展应用领域,加快高速钢的产业发展。
It is introduced the concept, composition and classification of HSS. Its production history in China includes six periods since 1918： beginning, imitation, create, import substitution, professionalization, internationalization and now China has become a world power in HSS. In research about change of high speed steel varieties in recent 5 years, a trend is represented： amount of hot rolling bars reduced, but bright steels increased; forging materials and flat steel decreased, but forging stock, forging pieces and tool blank increased. The HSS made in our country has been able to basically meet the requirement of domestic market with a large quantity to export and a little to import. In generally, its export growth is over its import growth, its production capacity is excess, market demand is decreasing. It is suggested： to have a global perspective, promote the international competitiveness; become more professional, stronger, and strive for benchmarking; set up excellent thinking, realize meticulous management; improve service quality, expand application field, speed up the development of HSS industry.
