该数据集主要对马鞍山钢铁股份有限公司生产的99mm翼缘厚度规格热轧H型钢进行低温冲击性能的检测,该数据中检测对象同一批号3种不同工艺方法生产成品,采用55×55×10mm标准冲击试样进行检测,试验温度为-40℃,通过冲击试样锤断吸收的能量评价材料的低温冲击性能。
This data set mainly tests the low temperature impact performance of 99mm flange thickness hot-rolled H-section steel produced by Maanshan Iron and Steel Co., LTD. In this data, the test object is the same batch number and three different processes are used to produce finished products. Standard impact samples of 55×55×10mm are used for testing, and the test temperature is -40℃. The low temperature impact properties of materials were evaluated by the energy absorbed by impact samples.
