It will be one of effective means to improve the performances of hot-rolled section steel to replace the microalloy addition with green, energy-saving, low-cost and resource-friendly controlled cooling technology after rolling. The metallographic structure of product with controlled cooling after hot rolling is ferrite + pearlite, the morphology is fine, performance is uniform, yield strength is increased by about 70~100 MPa and tensile strength is increased by about 80~150 MPa. In the paper, the research ideas, methods, experimental simulation and application examples of controlled cooling after rolling for high-strength section steel are introduced by taking angle steel as an example. The results show that the experimental data and simulated results are consistent with the production practices, which proves that the research method proposed in this paper is accurate and effective so that it can provide the reference for researching controlled cooling of angle steel and other hot-rolled section steels.

采用绿色、节能、低成本、资源友好型的轧后控制冷却技术代替微合金添加将成为提高热轧型钢性能的有效手段之一。经热轧后控制冷却的产品金相组织为铁素体+珠光体,且形态细小、性能均匀,屈服强度提高约70~100 MPa,抗拉强度提高约80~150 MPa。文章具体以角钢为例介绍了高强型钢轧后控制冷却的研究思路、方法、实验模拟以及应用实例。结果表明,试验数据和模拟结果与生产实践吻合,证明了本文提出的研究方法准确、有效,可为角钢以及其它热轧型钢控制冷却的研究提供参考。

采用绿色、节能、低成本、资源友好型的轧后控制冷却技术代替微合金添加将成为提高热轧型钢性能的有效手段之一。经热轧后控制冷却的产品金相组织为铁素体+珠光体,且形态细小、性能均匀,屈服强度提高约70~100 MPa,抗拉强度提高约80~150 MPa。文章具体以角钢为例介绍了高强型钢轧后控制冷却的研究思路、方法、实验模拟以及应用实例。结果表明,试验数据和模拟结果与生产实践吻合,证明了本文提出的研究方法准确、有效,可为角钢以及其它热轧型钢控制冷却的研究提供参考。

It will be one of effective means to improve the performances of hot-rolled section steel to replace the microalloy addition with green, energy-saving, low-cost and resource-friendly controlled cooling technology after rolling. The metallographic structure of product with controlled cooling after hot rolling is ferrite + pearlite, the morphology is fine, performance is uniform, yield strength is increased by about 70~100 MPa and tensile strength is increased by about 80~150 MPa. In the paper, the research ideas, methods, experimental simulation and application examples of controlled cooling after rolling for high-strength section steel are introduced by taking angle steel as an example. The results show that the experimental data and simulated results are consistent with the production practices, which proves that the research method proposed in this paper is accurate and effective so that it can provide the reference for researching controlled cooling of angle steel and other hot-rolled section steels.
