为了解决非金属夹杂物对钢力学性能的破坏问题，开发了电渣重熔（ESR）技术（1 - 6）。如今，电力、航空、冶金、机械等领域对钢材的要求越来越高，电渣重熔工艺变得越来越重要。从动力学角度看，金属与渣的界面面积越大，夹杂物的去除效率越高。Li et al.7)进行了电渣重熔实验，从耗材电极、电极尖端熔膜、炉渣中的金属液滴和最终钢锭中采集了样品。采用金相法、化学法和放射性同位素法对样品中的夹杂物进行了定量测定。结果表明，在电极的耗材端部清洗次数最多。耗材电极端液滴的演化行为是影响金属与渣界面面积的关键因素之一。横向静磁场对低频电渣重熔过程中熔滴演化行为的影响
To settle the problem of nonmetallic inclusions damaging the mechanical properties of steels, electroslag remelting (ESR) technology1–6) was developed for its excellent purification efficiency. Nowadays, the ESR process has become more and more important for the increasingly high requirements of the steels in areas such as electricity, aviation, metallurgy, machinery and so on. From a dynamic view, a larger interfacial area between metal and slag leads to a better removal efficiency of the inclusions. Li et al.7) conducted the ESR experiments and took the samples from the consumable electrode, the molten film on the electrode tip, metal droplets in the slag and the final ingot. The quantitative determination of inclusions in the samples were made by metallographic, chemical and radioisotopic methods. The results showed that the cleaning happened the most at the consumable electrode tip. The droplet evolution behavior at the consumable electrode tip is one of the key points in influencing the interfacial area between metal and slag.
