Electric Arc Furnace Slag

The electric arc furnace (EAF) process for steelmaking of Cr and Ni high alloyed stainless steel grades differs significantly from the steelmaking process of carbon steel due to the special raw materials and generally lower oxygen consumption. The special slag chemistry in the EAF process affects slag foaming and refractory wear characteristics due to an increased content of CrOx. A special slag diagram is presented in order to improve monitoring and control of slag compositions for Cr alloyed heats, with special focus on saturation to MgO periclase and dicalcium silicate C2S in order to minimize MgO losses from the refractory lining and to improve slag refining capability by avoidance of stable C2S. With the same diagram different EAF process strategies can be efficiently monitored, either at elevated CaO and basicity with lower spinel concentration and more liquid process slags near C2S saturation or at lower CaO content and basicity with increased spinel concentration and stiffer slags at MgO saturation but certainly no C2S stability. Examples for three industrial EAFs are given.

Flow control devices made of refractories are established in the tundish to modify the flow characteristics. In practical producing, the metallurgical function of flow control devices is weakened because of refractories corrosion. In this subject, an index named refractory wear factor which is used to evaluate the refractory wear was defined at first. And then, the characteristics of molten steel flow and the distribution of temperature and the refractory wear factor in a one-strand tundish equipped with flow control devices of a turbulence inhibitor, a weir and a dam were numerically simulated using the commercial CFD software. At last, the influence on refractory wear factor was analyzed. The following results were obtained. The high-speed molten steel is mainly confined to the injecting zone, especially to the turbulence inhibitor. The walls around the entering zone tundish and the weir wall faced to the flow direction have higher temperature than other walls. The highest value of refractory wear factor is focused on the inhibitor and bottom wall near the outlet. In order to keep the synchronization for the tundish, the refractories used in those zones should have higher anti-wear properties.
