The dual-fluid dual-metal hammerhead is a wear-resistant component that is formed by metallurgical bonding of high-hardness wear-resistant alloys (such as high-chromium cast iron) and high-toughness alloy steel. It is mainly used in high-wear scenarios such as mining crushing and cement production. The dual-fluid dual-metal hammerhead achieves a balance of "hardness without brittleness, toughness and wear resistance" through liquid-liquid composite casting. The key lies in precisely controlling the pouring sequence, interface reactions, and heat treatment processes. With the application of technologies such as lost foam vacuum casting and alloy composition optimization (such as adding Nb/V to refine grains), this process is evolving towards higher reliability and customization.
Products Description
The double liquid bimetal hammer is combined with high hardness wear-resistant alloy and high toughness steel through metallurgical composite process, which takes into account impact resistance and wear resistance, and its core advantages are obvious.
1. Performance advantages
Ultra high wear resistance
The working part of the hammer head is made of high chromium cast iron (Cr 15%-28%), and the hardness can reach HRC 58-65. The wear resistance is 3-5 times higher than that of traditional high manganese steel, which greatly extends the replacement cycle.
Strong impact resistance
The hammer handle uses low carbon steel or low alloy steel (such as ZG270-500,42CrMo), impact toughness αku ≥50J/cm², effectively resist the high strength impact force in the operation of crusher.
High reliability of composite interface
Through liquid-liquid thermal composite casting (such as quantitative pouring and partition method), a metallurgical bonding transition layer is formed at the interface, and the bonding strength is far higher than that of mechanical embedding, completely solving the risk of "dropping head" and "breaking head".
2. Economic benefits
Life cost is higher than optimization
Although the initial cost is higher than ordinary hammer (about 20%-30%), but because the life is more than three times longer, the unit crushing cost can be reduced by more than 20%.
Maintenance costs are reduced
Reduce the frequency of downtime replacement and improve the continuous operation efficiency of equipment, especially suitable for high wear material crushing scenarios such as high silicon limestone and granite.
3.Process & Design Innovations Metallurgical Bonding Technology:
Metallurgical bonding technology
Hot composite casting: two kinds of metal liquid are cast in one time at high temperature and melt to solve the problem of delamination at the bonding surface. Swallowtail lock structure: mechanical bonding is added to increase the shear strength by more than 30%.
Heat treatment intensification
The double process of overall quenching (960-1010℃) and low temperature tempering (200-500℃) can simultaneously optimize the wear resistance of hammer head and toughness of hammer handle.
Biluble bimetal hammer is often used in: high hardness material crushing (granite, quartz), cement clinker, metallurgical slag treatment, continuous mining crushing line and other industrial operations.
