Product Description

60mm Diameter R32 Light Thread High Temperature Resistant Blast Furnace Drill Bit for Taphole Opening

Specialized all-steel drill bit engineered specifically for blast furnace taphole opening operations. Features R32 light thread connection, 60mm diameter, and compatibility with blast furnace taphole opening machines. Delivers stable, efficient performance under extreme conditions of high temperature, intense wear, and strong impact.

Technical Specifications

Drill Bit Diameter	60mm (suitable for standard blast furnace taphole diameter)
Connecting Thread	R32 light thread for quick connection to R32 threaded drill rods/taphole openers
Structure Type	All-steel cross-shaped design, integrally forged
Applicable Equipment	Blast furnace hydraulic taphole opener with R32 threaded drill rod system
Working Environment	High temperature (≥1200°C), high wear, and strong impact conditions

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)
