12CrNi_3MoV钢是一种高强度高韧性的低合金钢,原成份中不含硼,由于脱氧时硼以复合脱氧剂的成份带入钢中,硼的波动范围为0.0009～0.0039％。本文用物理化学相分析方法研究了硼在钢中的状态及其对钢性能的影响。 一、试验用材 试样取自现场生产钢板,其酸溶硼含量分别为0.0032,0.0023,0.0019,0.0012,0.0009％。 二、用正交设计法选择电解制度 电解制度的选择包括电解液成分、电流密度、电解温度以及连续电解的时间。使用
12CrNi_3MoV steel is a high strength and toughness of low alloy steel, the original composition does not contain boron, boron deoxidation due to composition of composite deoxidizer into the steel, boron fluctuation range of 0.0009 ~ 0.0039%. In this paper, the physical and chemical phase analysis of boron in the steel state and its impact on steel properties. First, the test material samples taken from the site production of steel, the acid-soluble boron content of 0.0032,0.0023,0.0019,0.0012,0.0009% respectively. Second, the use of orthogonal design choice of electrolysis system The choice of electrolysis system, including electrolyte composition, current density, electrolysis temperature and continuous electrolysis time. use
