Tapping Hole Fillers

What is Tapping Hole Fillers?

Tap hole filling mass is used in the EAF tap hole to prevent molten steel from flowing into tap hole before tapping. On the exposed surface of the filling mass produces a sintered layer thick enough to prevent molten-steel penetration, at the same time, thin enough to allow it to break out under the pressure of the molten-steel when the tap hole is opened and filling mass beneath the sintered layer flows can come out freely.
Changxing series of tap hole filling mass features easy installation, safe application, non-floating, high self-opening rate and non-pollution etc.

EBT Filling Mass is used in Electric Arc Furnace ( EAF ) for smooth and easy operation. Being free flowing in nature it ensures trouble free opening of tap hole. High sintering point, low thermal conductivity and well balanced granule size is the key to successful product performance of NozzoFill – EBT Filling Mass.

Site of use: center bottom and eccentric bottom outlet of EAF
