通过实验总结和分析了鞍钢中型热轧角钢(7.5～10号)的力学性能、金相组织与控冷工艺的关系:终冷温度对角钢的强塑性起着决定性作用,A3.16Mn角钢的终冷温度控制在700～650℃范围内具有较高的强塑性配合;碳当量C_eq影响A3、16Mn角钢控冷后强化效果,一般碳当量高强化效果大;A3角钢经轧后控冷后欲达到16Mn角钢的力学性能水平,需使碳当量C_eq≥_0.27,终冷温度控制在700～650℃范围内。
The relationship between mechanical properties and microstructure and controlled cooling process of Angang middle-sized hot-rolled angle steel (7.5-10) was summarized and analyzed through experiments: the final cooling temperature plays a decisive role in the ductility of angle steel, the final of A3.16Mn angle steel Cold temperament control in the range of 700 ~ 650 ℃ with a high degree of plasticity; carbon equivalent C_eq A316Mn angle after cooling effect of strengthening the control, the general effect of carbon equivalent high strengthening; A3 angle after rolling to achieve after cooling The mechanical properties of 16Mn angle steel should be such that the carbon equivalent C_eq≥_0.27 and the final cooling temperature controlled in the range of 700 ~ 650 ℃.
