EAF Tap Hole Filling mass

Tap hole mass is used in the EAF nozzle during the smelting process to prevent the molten metal from entering the nozzle. The exposed surface of the sand produces a sintered layer thick enough to prevent molten metal penetration yet thin enough to allow it to break under the pressure of the molten metal when the nozzle is opened and the free flowing sand beneath the sintered layer flows out of the open nozzle. SG series of tap hole mass has the characteristics of easy to install, non-floating, high free open rate, safe to use and non-polluting.
