Abstract
Steel plate making can be produced by hot and cold rolling method. To obtain the optimal results, the production on the cold rolling mill (CRM) must be carried out continuously. This CRM is equipped with a flash butt welding machine to connect between one plate and anothers. The purpose of this research is to determine the effect of thickness reduction on mechanical properties of steel JIS 3141. The method used in this study is experimental, namely mechanical properties testing at weld area, heat affected zone (HAZ) and base material. The thickness reductions used in this research are 0%, 69,78%, 71,56% and 73,33%. The material characteristics observed were hardness, tensile strength, yield strength, elaongation and corrosion rate. From this study it is known that the thickness reduction 73.33% resulted the best mechanical properties. The values of hardness, tensile strength, yield strength and corrosion rate were 82.26 HRB, 644 N / mm2, 501 N / mm2 and 1.3844 mpy, respectively.
钢板可采用冷轧法和热轧法生产。为了获得最佳效果，冷轧机上的生产必须连续进行。该CRM配备了闪光对焊机，以连接一个板和另一个板。本研究的目的是确定减薄对JIS 3141钢力学性能的影响。本研究采用的是实验方法，即焊接区、热影响区和基材的力学性能测试。本研究采用的厚度减薄分别为0%、69、78%、71、56%和73、33%。观察材料的硬度、抗拉强度、屈服强度、伸长率和腐蚀速率。结果表明，当厚度减小73.33%时，合金的力学性能最佳。硬度、抗拉强度、屈服强度和腐蚀速率分别为82.26 HRB、644 N / mm2、501 N / mm2和1.3844 mpy。
