摘要
为了降低电渣重熔过程中电渣锭的增氢量,以316H钢为研究对象,对自耗电极中的初始氢含量、渣料成分、空气湿度的影响进行了分析,并在此基础上提出相应的改进措施.改进实施后增氢量由原有的平均2.2 × 10-6降至平均1.3 × 10-6以下,其电渣锭中氢含量平均降低了0.9×10-6,降低率达到了41％,有效控制了电渣锭的增氢量.
Abstract
In order to reduce hydrogen pick-up during the electroslag remelting,taking 316H steel as the research object,the influence of the initial hydrogen content,slag composition and air humidity of the consumable electrode were analyzed,and on this basis,the corresponding improvement measures were put forward.After putting these measures into practice,the hydrogen increment amount was decreased from the original average 2.2×10 to the average 1.3×10-6 below,and the average hydrogen content in the electroslag ingot was reduced by 0.9×10-6,reaching a reduction rate of 41％.The hydrogen increment amount of the electroslag ingot was effectively controlled.
