Eccentric Bottom Tapping (EBT) EAF prevents flow of slag into the ladle while tapping. A fresh slag with proper basicity ratio is again created in the ladle for further refining of the steel in LRF. Double slag process is practiced for removing P2O5 and CaS from slag. Fig Furnace for Refining Steel. Slag free tapping from EAF

EAF slag is removed from the furnace and is not allowed to enter the ladle during tapping. Eccentric Bottom Tapping (EBT) EAF prevents flow of slag into the ladle while tapping. A fresh slag with proper basicity ratio is again created in the ladle for further refining of the steel in LRF.

Steel making Technology EAF EAF is widely used in USA. The capital cost is lower as compared to BOF (also known as LD). EAF process uses predominantly scrap. DRI is an alternate iron ore bearing material, which is used when the scrap is not available. A new process, which is known as 'CONARC' has been developed by SMS DEMAG.

Here, pellets are formed through the rotation of the disc in the presence of a binding agent (in this case water) in a process referred to as coalescence. Ideal pellet size range for the EAF dust recycling process is typically around 1/6" to ¼". Once pellets have reached the desired size,...
