摘　　要：微合金元化元素的应用范围越来越广泛 ,如今已成为控轧钢必不可缺的元素 ,而且 ,也越来越多地应用到了调质钢的生产。尤其是硼、钛、铌元素在调质钢中的加入 ,不但能提高调质钢的淬透性 ,而且有利于焊接甚至大线能量焊接性能 ,为调质高强钢在大型工程项目中的应用起到了关键作用。The micro-alloying elements have found wider and wider application,they have now become indispensable elements for controlled rolled plate,moreover,they are being used more and more in the production of quenched and tempered plate.in particular,the addition of boron,titanium,niobium in quenched and tempered steel can not only enhance the hardenability of quenched and tempered steel,but also be favourable for welding,even for high heat input weldability,playing a key role in the application of quenched and tempered high strength steel in large-scale engineering projects.
