钢中氢的来源及控制对策

Controlling countermeasures for the source of hydrogen in the steel

通过采用浸入式直读测氢仪对“转炉炼钢＋LF炉＋连铸”过程中[H]的来源进行研究，试验结果表明：转炉冶炼、LF精炼、浇注过程均存在钢水增[H]现象。增氢原因有：原辅材料及合金水分、系统耐材水分、耐材化学成分分解的碳氢化合物、钢液二次氧化导致钢水增[H]。分析影响钢液增氢的主要因素及环节．并提出了改进措施。

The resource of hydrogen during process-- steel-making with conventer＋LF furnace＋continuous casting was researched by using hydrogen instrument. The results show that hydrogen increased among conventer, LF furnace and casting, the reasons as follows： water and hydrocarbon of materials, alloy and refactory materials and oxidation of steel smelting. In order to solve the problem, improving mesures were put forward.
