摘　　要：为减少510L汽车大梁钢由于成分波动而导致的性能变化,应用低碳加高锰及微合金化元素的化学成分的设计思路,利用控制冶炼工艺及轧制工艺试验生产钢板。试验结果显示:试验生产的510L汽车大梁钢板的化学成分在标准要求范围内;轧制以后组织为铁素体和珠光体,各项力学性能指标都在标准的要求范围之内。In order to reduce the performance change caused by the fluctuation of composition of 510L automobile girders, the design of chemical composition of low carbon and high manganese and microalloying dements is applied, and the steel plate is produced by controlling the smelting process and rolling process. The test results show that the chemical composition of the 510L automobile girder steel plate produced by the test is in the standard requirements; after rolling, the microstructure is ferrite and pearlite, and the mechanical properties are all within the requirements of the standard.
