چکیده انگلیسی
Targeted at the 3000Â kVA and 1500Â kVA electric arc furnaces for MgO production, 3D models are developed to characterize the thermal behavior in the furnaces. The electromagnetic stirring effect of the molten bath is studied respectively with a rated current, and its influence on the temperature field is predicted by the model in FLUENT. Some calculated results are proved reliable by comparison with the measurements. It can be seen that a stronger stirring effect leads to a higher average flow velocity in the 3000Â kVA furnace, and the size of its molten bath is much larger than that in the 1500Â kVA furnace. The appropriate location of the three electrodes can help to maintain a homogenous bath temperature distribution. The comparison between the calculated results and the measurements proves that the dimensional designs of the two furnaces are acceptable for the prevention of the local overheating or overcooling. Large-capacity electric arc furnaces are qualified with significant advantages in energy conserving and increase of productivity.
