Understanding Electric Arc Furnace Steel Making Operations

Understanding Electric Arc Furnace Steel Making Operations. It is advantageous to remove as much P into the slag as early in the heat as possible. The furnace is tilted backwards and slag is poured out of the furnace through the slag door. Removal of the slag eliminates the possibility of P reversion.
