The converter tap‑hole renewal machine is special‑purpose equipment, different from the general furnace demolition machine. It is dedicated to drilling, reaming, blockage removal and sleeve brick replacement for converter tap‑holes, and is not used for large‑area refractory lining demolition.
Drilling & Reaming to Unclog Tap‑hole Drill out clogged cold steel, slag and sintered filling materials. Repair worn, eccentric and deformed tap‑hole passages, restore standard bore diameter to ensure smooth molten steel tapping, and reduce slag entrapment and eddy‑current erosion on sleeve bricks.
Removal of Worn Tap‑hole Sleeve Bricks Adopt hydraulic rotary impact drill to break and take out worn, cracked and eroded old sleeve bricks, clean residues inside the hole without damaging the surrounding seating brick base.
Precise Clamping and Compression of New Sleeve Bricks The hydraulic gripper grabs new sleeve bricks, realizes coaxial positioning and uniform compression, guarantees good concentricity and sealing, and eliminates risks of steel penetration and steel leakage.
Overall Tap‑hole Rehabilitation & Refurbishment Repair offset, enlarged and irregular hole passages, restore standard diameter, angle and depth, extend tap‑hole service life and reduce refractory consumption.
Safe & Fast Operation with Reduced Downtime Wireless remote‑control operation keeps operators away from high‑temperature splashes. The whole process including drilling, slag cleaning and sleeve brick replacement only takes 10‑20 minutes. It shortens auxiliary maintenance time of converters and increases steel‑making heat output.
