摘　　要：对莱钢生产的铌微合金化H型钢进行了总结。介绍了型钢产品生产工艺流程,探讨了生产过程中如何控制加热制度和热轧工艺等问题,重点解决了铌微合金化钢种的生产中出现的问题,为同类钢种的开发与生产提供重要的参考基础。Development of hot - rolled H - beam using niobium mieroally in Laigang was summarized. In this paper, the production process of H - beam awas introduced, how to control the heating system and hot rolling in production were discussed, and the problems appeared in niobium microallying production were solved. It is a ponderability use for reference acting for the development and production of uniformity steel grade.
