The impact of the material of the hammer on the service life of the high manganese hammer

 The impact of the material of the hammer on the service life of the high manganese hammer

 

Generally speaking, the greater the hardness of the hammer, the greater the wear resistance. To improve the wear resistance of the hammer, it is necessary to increase its hardness, but as the hardness increases, the impact toughness of the hammer will decrease. Therefore, how to balance the appropriate hardness and good impact toughness of the hammer is the key to improving the wear resistance of the hammer.

Commonly used materials for hammers are: high manganese steel, high chromium cast iron, and TiC inserted high manganese steel.

 

High manganese steel has good toughness, good manufacturability and low price. Its main feature is that under the action of greater impact or contact stress, the surface layer will quickly produce work hardening, and its work hardening index is 5 to 7 times higher than other materials. The wear resistance is greatly improved. However, if the impact force is not enough or the contact stress is small in use, the surface cannot be quickly worked hardened, and the wear resistance of high manganese steel cannot be fully exerted.

 

The TiC inserted high manganese steel hammer is made by inserting and casting Titanium carbide cermet rods or alloy blocks on the working surface of the hammer by a special process method. It has high anti-wear effect and Have reliable safety performance. Effectively solve the contradiction between hardness and toughness, so that it can adapt to various complex and harsh working conditions.

 

the characteristics of TiC inserted high manganese steel hammer

1. The TiC inserted high manganese steel hammer adopts the technology of out-furnace refining and integral pressure casting, and the matrix is more compact, which is especially suitable for working under severe abrasive wear conditions.

2. The TiC inserted high manganese steel hammer is especially suitable for crushing hard, high SiO2 and strong abrasive limestone. The life of the hammer is 50-100% longer than that of the ordinary high manganese steel hammer, and the use is safer and more reliable.

3. The TiC inserted high manganese steel hammer has super wear resistance, which is especially suitable for industries with harsh rock conditions such as cement plants and sand and gravel plants.
