Molten steel/iron is transferred out using a ladle & skulls are formed in the ladle due to rapid cooling and spillage during pouring. Reducing the loss from skull formation creates benefits in output ratio and volume.
When the raw materials are loaded on to the furnace they undergo a high thermal melting process and attain the molten state. This molten steel/iron has to be transferred to different places for further processing which are usually carried out by the giant ladles. When molten steel is tapped out of the ladle they undergo rapid cooling and form skulls within the walls of the ladle. A lot of spillage also occurs when they are poured out in the pig casting molds causing the skull to be thrown away onto the floor and they pick up dust and solidify making them unusable and recyclable without reprocessing. Preventing skull formation by careful handling and maintaining the ladle temperature will increase total volume output by 1-2%.
