摘　　要：通过对钛微合金化技术的研究,在普通低合金钢的基础上添加钛微合金化元素,结合板材控轧、控冷技术控制微合金元素的析出行为,获得良好的力学性能,在中厚板机组上成功研制出钛微合金化Q345C钢,并作为一种低成本的低合金高强度钢批量应用于中厚板生产。Through the study of Ti micro alloying technology,micro alloying elements Ti are added on the basis of ordinary low alloy steel,and the precipitation behavior of micro alloying elements is controlled by controlled rolling and controlled cooling technology to obtain good mechanical properties,the Ti micro alloyed Q345 C steel is successfully developed on medium and heavy plate production line. As a low cost low alloy high strength steel,it is used in the production of medium and heavy plate.
