Tungsten Carbide Button for Rotary Drilling Rig

Introduction

Rotary drilling rig is a construction machine suitable for hole forming in building foundation engineering. It is mainly suitable for soil layer construction such as sand, cohesive soil and silty soil. It is widely used in various foundation construction such as cast-in-place pile, continuous wall and foundation reinforcement. The rated power of rotary drilling rig is generally 125-450kW. The output torque is 120-400kN·m, the maximum hole diameter can reach 1.5~4m, and the maximum hole depth is 60-90m, which can meet the requirements of various large-scale foundation construction.

Tungsten carbide button for rotary drilling rig use raw and auxiliary materials such as primary saturated tungsten carbide, high-purity ultra-fine cobalt powder, precise carbon formulation, tilting ball mill, vacuum stirring and drying, precision pressing, digital degreasing sintering and pressure sintering. Advanced powder metallurgy process, such as treatment, has good hardness, high hardness, good wear resistance, high elastic modulus, high compressive strength and good chemical stability, low impact toughness, low expansion coefficient and other characteristics.
