摘要
针对承钢公司低合金高强度Q345B钢板存在屈服强度波动范围大、延伸率偏低、使用冷弯过程开裂、生产成本偏高等问题,结合承钢钒钛资源特色,提出利用钒微合金化工艺生产Q345B钢,采用提钒、降硅、降锰措施后,提高了产品质量,降低了生产成本。
To solve the problems of low-alloy high-strength Q345 steel plate： large change range of yield strength,low elongation,cracking in cold bending,relative high cost and so on,it is proposed to produce Q345B steel with vanadium-microalloying process,and with measures adopted： vanadium extracting,silicon reducing,manganese reducing,the quality of products improved,the cost lowered.
