During scrap charging, a huge amount of hot gas and dust leave the EAF. Depending on the amount of organic impurities in the scrap, the gas emission can exceed the design throughput of the secondary exhaust gas system. In this case a cloud of dust could enter into the melt shop resulting in too high dust loads in some areas. The video shows that dust particles enter the shop next to the EAF. The hot, dust-free off-gases from the ladle heaters in the left-hand shop area drive the hot, dust-laden off-gases from the left to the right side. This undesired flow pattern can be avoided, e.g. by attaching baffles and/or curtains, and by positioning the ladle heaters in a more symmetrical arrangement.
