摘要
介绍了Q420B高强度角钢的工艺研究与质量控制,认为通过采用合理的钒氮微合金化工艺和合理的冶炼、精炼、连铸工艺,能生产出质量和轧材性能均符合有关标准要求的Q420B高强度角钢。
The steelmaking process and quality control method of Q420B high strength angle steel is introduced. The results show that the quality and performance of Q420B can meet the standard requirements through the rational process of smelting, refining, continuous casting and micro-alloying with V and N.
