高韧性热轧管线用钢主要用于制造石油和天然气输送管。这种钢要求具有良好的综合性能，既要有较高的强度和韧性，又要有良好的焊接性能和较低的脆性转变温度，其化学成分的特点是低碳、低硫、高锰和添加微合金元素。轧制中采用了控制轧制和控制冷却的新工艺。文中对控轧工艺及轧制力能参数进行分析研究，并利用模拟实验所得到的结果，提出此种钢较好的轧制工艺制度。 High toughness hot-rolled pipeline steel is mainly used in the manufacture of oil and gas pipelines. This steel requires a good overall performance, both high strength and toughness, but also have good welding properties and low brittle transition temperature, the chemical composition is characterized by low-carbon, low sulfur, high manganese and Add microalloying elements. Rolling used in the control of rolling and control of the new cooling process. In this paper, the control rolling process and the rolling force energy parameters are analyzed and studied, and the results of the simulation experiments are used to propose a better rolling system for this kind of steel.
