摘　　要：通过分析钢的化学成分、夹杂物情况等对性能的影响,采取优化冶炼工艺及轧制工艺的措施,合理控制了碳当量及夹杂物的形态、分布,在钢板的强度不降低的情况下,提高了塑性,冷弯试验合格率达100。By analyzing the effect of chemical contents and inclusions on properties, adopting the measures for optimizing smelting and rolling process, the carbon equivalent and the form and the distribution of the inclusions were controlled reasonably, on the condition of retaining the strength of the steel plate, its plasticity was improved and the pass percent of the coldbending test reach 100 percent.
