Design & Construction
Structural Integrity
All-steel unibody forging creates uniform wall thickness, delivering exceptional strength with superior torsional and bending resistance.
Cutting Efficiency
Cross-cutting edge layout ensures smooth slag removal and minimizes drill jamming during operation.
Cooling System
Built-in four corner vents enable forced air cooling for rapid heat dissipation and reduced thermal loss.
Materials & Manufacturing
- Cutter Head: High-strength wear-resistant alloy steel with special heat treatment for high temperature resistance, impact resistance, and minimal wear
- Base Body: High-quality structural steel with integral reinforcement, balancing toughness and rigidity for high-frequency impact operations
- Welding Technology: High-frequency/shielded welding ensures strong bond between cutter head and base body, preventing high-temperature detachment
Performance Advantages
- High-Efficiency Opening: Sharp cross-blade cutting reduces drilling resistance and improves furnace operation efficiency
- Durable & Damage-Resistant: All-steel construction with air-cooled design withstands extreme blast furnace temperatures and slag abrasion
- Stable & Reliable: Optimized permeable slag discharge structure prevents overheating, softening, jamming, or chipping for continuous operation stability
- High Compatibility: R32 standard thread compatible with mainstream blast furnace taphole opening equipment and drill rods
Application Scenarios
- Blast furnace taphole opening - drilling through taphole clay and refractory material layers for safe molten iron discharge
- Metallurgical furnace maintenance - drilling operations at furnace mouths of small and medium-sized blast furnaces and ferroalloy furnaces
- Mining/metallurgical support - blasting holes and tunnel excavation in medium-hard rock (f8-f12)
