This product is a tapered structural component manufactured using high-performance reaction-bonded silicon nitride ceramic, featuring a gray-black appearance with a precision-polished mirror-grade surface finish. The innovative design integrates a pointed conical top with a hexagonal base, incorporating precisely engineered micro-orifices for dual functionality in fluid guidance and mechanical fixation. Silicon nitride material, renowned for its exceptional mechanical properties and corrosion resistance, is the ideal choice for demanding operating conditions.
Superior Wear Resistance: Hardness up to Hv1500-1700, with wear resistance 5 times greater than cemented carbide
Excellent Thermal Stability: Capable of continuous operation at 1400°C, withstanding thermal shock differentials up to 900°C
Optimized Fluid Dynamics: Tapered structure ensures smooth material flow with minimal pressure loss
Anti-Jam Design: Hexagonal base facilitates tool clamping for easier installation and maintenance
Extended Service Life: 8-10 times longer lifespan compared to conventional materials under identical conditions
Surface Treatment: Sandblasting nozzle tips, shot peening flow guides
Resource Exploration: Geological drilling guide heads, oil and gas metering components
Precision Manufacturing: Wire EDM guide wheels, automated equipment positioning taper sleeves
Special Processes: Powder metallurgy feed nozzles, chemical atomization nozzles
