High Temperature High-Purity Graphite Fused Large-Crystal Magnesia Resistance Tapholes for Eaf Tap

High Temperature High-Purity Graphite Fused Large-Crystal Magnesia Resistance Tapholes for Eaf Tap. High Temperature Resistance Tapholes for EAF Tap is manufactured with fused large-crystal magnesia as the main raw material, combined with high-purity graphite and metallic anti-oxidants. Phenolic resin is adopted as the binder. It is formed by cold isostatic pressing for monolithic tap holes or mechanical pressing for split-type tap holes. The product features excellent oxidation resistance, high strength, superior slag erosion resistance, easy installation and replacement, and long service life. High Temperature Resistance Tapholes for EAF Tap is a core component for electric arc furnace steelmaking. It precisely controls molten steel outflow, realizes slag-free or low-slag tapping, protects the furnace body and ladle, and ensures molten steel quality and production efficiency. As the only passage for molten steel flowing from the furnace to the ladle, it regulates flow velocity and capacity accurately via its dimension. angle and opening-closing mechanism, preventing splashing, turbulent flow and reoxidation.It also cuts down furnace tilting angle, lowering stress on the furnace body and load on the water cooling sys. Eccentric Bottom Tapping (EBT) is the mainstream technology currently applied. It separates slag from steel by retaining residual molten steel. greatly limiting slag entry into the ladle and laying a foundation for secondary refining. Our EAF tap hole adopts optimized flow channel design to reduce eddy current erosion of molten steel, extending the service life of both the tap hole and ladle lining.
