High-Performance Taphole Drill Bits for Blast Furnace
HENGLONG blast furnace tapping drill bits deliver superior quality, ensuring optimal efficiency and extended lifespan for your blast furnace and ferroalloy application equipment. Our specialized materials and manufacturing processes are engineered to enhance machine performance, stability, and reliability.
These specialized carbide drill bits are designed specifically for taphole opening operations in metallurgical blast furnaces, offering exceptional high-temperature resistance, superior wear resistance, and efficient tapping performance.
Product Specifications
Design & Construction
Main Structure: High heat-resistant steel base with cemented carbide cutting teeth composite structure
Ventilation System: Base features ventilation holes for forced air cooling and rapid heat dissipation
Drill Diameter Range: 33 mm to 65 mm
Cutting Edge: Maintains sharp cutting edge for clean material cutting rather than hammering
Material Composition
Cutting Teeth: Cemented carbide using special sintering process for high temperature, wear, and impact resistance
Base Material: Heat-treated and strengthened carbon steel with high strength and excellent toughness
Bonding: Protective welding ensures strong bond between alloy teeth and base, preventing detachment
Carbide teeth combined with air-cooled structure provide superior high-temperature resistance and thermal fatigue resistance, reducing replacement frequency and consumable costs.
Superior Stability
Optimized venting design facilitates effective slag removal and cooling, preventing drill bit overheating and softening while ensuring stable drilling and minimizing risks of jamming or tooth breakage.
Our carefully selected materials ensure minimal wear, directly impacting the overall economic benefits and operational efficiency of your plant operations.
