Function
- Reshape and trim tap hole profile: Remove accreted cold steel, slag and worn refractory, restore standard round bore for smooth molten steel tapping.
- Unclog blocked tap hole: Break solidified steel and slag blockage without manual jackhammer work.
- Reaming for new tap hole sleeve brick: Prepare standard diameter for tight installation of new sleeve brick and reduce steel leakage risk.
- Continuous slag removal: Three spiral flutes discharge refractory chips and slag during reaming to avoid bit jamming.
Advantage
- Excellent chip / slag discharge by triple‑helix design, low risk of bit stuck.
- Cemented carbide cutting plates, high temperature resistance, impact & wear resistance.
- Balanced cutting force, good concentricity, straight and round finished tap hole.
- High strength alloy steel body, re‑hardfacing or replaceable cutter tips available, low operation cost.
- Fast reaming speed, reduce converter downtime and improve mill productivity.
- Customized diameter according to tap hole dimension.
