What are the materials of the cutting teeth of the rotary excavator?
Rotary excavator teeth are mechanical equipment used in earthwork engineering to drill holes, excavate, and break rocks in soil. The material of the cutting teeth of a rotary excavator has a significant impact on its working performance and service life. The following are several common cutting tooth materials and their characteristics of rotary excavators.
High manganese alloy steel: High manganese alloy steel is a special type of steel with extremely high hardness and wear resistance. This material can effectively improve the wear resistance of the cutting teeth and extend their service life when manufacturing rotary excavator picks. The main components of high manganese alloy steel are alloy elements such as carbon, manganese, silicon, sulfur, and phosphorus, which have good toughness and pressure resistance and can be used in harsh soil environments.
High speed steel: High speed steel is a specially treated tool steel with extremely high hardness, heat resistance, and wear resistance. Due to its excellent cutting performance, high-speed steel cutting teeth are widely used in the construction of rotary excavators. The main components of high-speed steel are alloy elements such as carbon, tungsten, molybdenum, and cobalt, which can maintain good blade stiffness and are not easily deformed under high-speed rotation and high temperature, making it suitable for high-strength rock excavation operations.
Hard alloy: Hard alloy is a metal material with high hardness and wear resistance, commonly used in the manufacturing of rotary excavator cutting teeth. The main components of hard alloys are metal hard compounds such as tungsten carbide and titanium carbide, with a hardness of over 1800 degrees Celsius. Hard alloy cutting teeth not only have good wear resistance and impact resistance, but also can adapt to various soil and rocks, and are widely used in earthwork engineering.
High hardness wear-resistant steel: High hardness wear-resistant steel is a specially treated wear-resistant material with excellent wear resistance, impact resistance, and crack resistance. High hardness wear-resistant steel can greatly improve the hardness and wear resistance of the cutting teeth when manufacturing rotary excavators, thereby extending their service life. This material has high strength and hardness, and can adapt to high-density, hard soil and rock working environments.
Cast steel: Cast steel is a high-strength and wear-resistant casting material commonly used to manufacture the cutting teeth of large rotary excavators. Cast steel has excellent mechanical and wear properties, can withstand high loads and impact loads, and is suitable for heavy-duty excavation and crushing operations. At the same time, cast steel has good plasticity and can produce complex shaped cutting teeth through casting technology, providing greater design flexibility.
In short, the material selection of the cutting teeth of the rotary excavator depends on the specific construction environment and work requirements. When selecting materials, it is necessary to consider factors such as the hardness, wear resistance, toughness, and machinability of the cutting teeth, in order to improve the service life and work efficiency of the cutting teeth. Different materials of cutting teeth have different adaptability and advantages in different soil and rocks, and the construction unit can choose the appropriate cutting material according to the actual situation.
