2013 中国铸造活动周论文集 Cr26MoWVTiRE合金铸铁溜槽衬板的开发与应用 李固成 (驻马店市永诚耐磨材料有限公司，河南驻马店463000 ) 摘要：针对钢铁企业高炉布料溜槽衬板所处的恶劣作业环境，研究开发出具有一定耐高温、耐腐蚀性 的Cr26MoWVTiRE 高铬合金铸铁材料，经1020 ～1050℃淬火 320 ～520℃回火，使材料宏观硬度 2 HRC达到60 ～62 ，aK ＞5J/cm 。特别是Mo、W 合金和V、Ti 等强碳化物元 的复合加入，提高了溜槽衬 板的硬韧性、红硬性和高耐磨性。经实际应用其使用寿命超过18个月，与镶铸(嵌)硬质合金溜槽衬板 相比，具有生产工艺简单、成本低、性价比高等特点，有一定积极推广应用价值。 关键词：溜槽衬板；高铬铸铁；耐高温；高抗磨性 Cr26MoWVTiRE Development and Application of Cast Alloy Iron Chute Lining Plate LI Gu-cheng (Zhumadian Yongcheng wear-resistant materials Co., Ltd., Zhumadian 463000 ，Henan) Abstract: Aiming at the bad working environment and distributing chute for iron and steel enterprises furnace liner at,Research and development of Cr26MoWVTiRE high chromium alloy cast iron material of high temperature resistance, corrosion resistance,After 1020℃-1050℃ quenching + 320℃-520℃ 2 tempering, the material hardness reached a higher level, HRC60-62, a , 5J/cm .Especially the composite by K adding Mo, W alloy and V, Ti and other strong carbide elements, To improve the toughness, chute lining board red hardness and high wear resistance, Through the practical application of the service life of more than 18 months, With cast-in (block) hard alloy chute lining board compared, Has the advantages of simple production process, low cost, high performance-cost ratio. There are certain positive value of popularization and application. Key words: chute lining board, high chromium cast iron, high temperature resistance, high abrasion resistance. 1 引言 我国钢铁工业自上世纪70 年代高炉炉顶装置由料钟式改为无料钟式结构以来，矿石由对大小料 钟的磨损变为一系列输料衬板的磨损。随着冶金装备技术的发展，当代大中型高炉冶炼强度不断提
