摘　　要：通过试验和分析,阐述了10B21钢中的硼在炼钢、连铸、轧制等过程中的经历,通过调整生产工艺,达到使硼在炼钢时不氧化,在凝固时不形成"硼相"BN,在轧制时抑制Fe23(C,B)6的形成,使硼从炼钢到轧制等4个过程中得以顺利形成为有益的酸溶硼,合理选择用户加工参数,提高钢的晶界上的酸溶硼量,提高产品的淬透性和冷加工性,从而达到发挥硼在钢中的作用这一目的。The experience of boron was expounded in process of steel-making and continuous casting and rolling by test and analysis.The boron has been not oxidized in steel-making.The BN phase has been not formed in continuous casting.Fe23（C,B）6 has been restrained in rolling by adjusting produce technology.Useful acid-solve boron（Bs） has been formed in the steel from steel-making to rolling.Acid-solve boron on boundary was increased by adjusting rational technology parameter of user,to improve the product hardenability and cold deformation property which function of boron was gived play to.
