【摘要】 为了梳理高炉风口小套的研究发展态势，对近二十年国内外对高炉风口小套的研究现状、研究热点进行了系统化的梳理和分析。同时，明确提升高炉风口小套使用寿命的重点研究方向。以近年与风口小套主题相关的文献作为研究数据源，对风口小套的服役情况、破损机理和表面强化技术的研究现状分析，探析风口小套的研究热点，提出激光表面仿生强化技术及其在风口小套上的应用是未来的发展趋势。结果表明铜基体上的激光仿生强化机理和仿生强化结构设计方法，是未来提升风口小套使用寿命的重点研究方向。更多还原

【Abstract】 In order to sort out the research and development trend of blast furnace tuyere sleeve, the research status and research hotspots of blast furnace tuyere sleeve at home and abroad in the past two decades were systematically sorted out and analyzed. At the same time, the key research direction of improving the service life of blast furnace tuyere sleeve is clarified. Taking the literature related to the tuyere sleeve theme in recent years as the research data source, this paper analyzes the research status of the service condition, damage mechanism and surface strengthening technology of tuyere sleeves, explores the research hotspots of tuyere sleeves, and puts forward that the laser surface bionic strengthening technology and its application in tuyere sleeves are the future development trend. The results show that the laser bionic strengthening mechanism and bionic strengthening structure design method on the copper substrate are the key research directions to improve the service life of the tuyere sleeve in the future.更多还原
