As a manufacturer specializing in carbide brazing for many years, we have achieved high quality and high working performance of carbide brazing hammers and breaking heads with our excellent carbide and welding production technology. Carbide welding products used in crushing, mining, recycling and conveying systems have becoming a market trend these days, so we believe to build partnerships under the base of "Customers First". ODM and OEM are both welcomed.
Today let me introduce you the comparison of several hammer materials in the market.
According to the material, crusher hammers can be divided into the following types: high manganese steel hammers, bimetal hammers, composite hammers, big gold teeth hammers, medium chrome alloy hammers, carbide hammers, etc. The main factor is silicon dioxide content. Modern industry shows that the use of cemented carbide hammers is more excellent in wear resistance.
Forged hammer
The hammer head of the forging crusher is suitable for crushing pebbles, coal gangue, limestone, etc. The hammer head of the forging crusher is made of high-quality train wheel hub steel (material 65Mn, good impact resistance, strong toughness, good wear resistance, not easy to break). The metal blank is repeatedly forged by forging machinery to deform it to obtain certain mechanical properties. , A certain shape and size, after a special quenching heat treatment method, to ensure that the working area of the hammer head has high hardness and high wear resistance. Through forging, defects such as as-cast looseness generated in the metal smelting process can be eliminated, and the microstructure can be optimized. At the same time, due to the preservation of the complete metal streamline, the mechanical properties of forgings are generally better than those of castings. Forging hammers are favored by the majority of users because of their low price, economical and durable features.
High manganese steel hammer
The alloyed high-manganese steel wear-resistant hammer has reliable quality and three times the wear resistance of traditional high-manganese steel.
With the continuous development of wear-resistant materials, high manganese steel has gradually become unsuitable for the development of modern foundry industry. Replaced by chromium molybdenum alloy steel, high chromium cast iron and nickel hard cast iron. However, the high toughness of high manganese steel is unmatched by other wear-resistant materials.
The high manganese steel crusher hammer has high requirements on the overall performance of the crusher. If the physical impact force is not enough or the contact stress is small in actual work, the surface cannot be work hardened quickly, so that it cannot exert its due wear resistance. .
High chrome alloy hammer
The high-gold alloy crusher has excellent hardness and is a high-quality wear-resistant material. It has been widely used in crushers with supporting hammer frames, but high-chromium alloys have poor toughness and are prone to occur without the support of hammer frames. fracture. High-chromium composite hammer, that is, high-manganese steel is used for the hammer handle, and high-chromium alloy is used for the working area of the hammer. The two are combined to make the hammer head have high hardness, while the hammer handle has high toughness, giving full play to the two The respective advantages of the material are used to overcome the shortcomings of a single material, and the performance requirements of the hammer head are met. Especially suitable for crushing high hardness materials, such as quartz stone, basalt, etc. However, its manufacturing process is complex, the process requirements are stricter, and the price is higher.
Carbide hammer
Compared with other materials, the cemented carbide hammer has higher hardness, bending strength and impact resistance, thermal fatigue resistance, good thermal hardness, cost-effectiveness, etc.
1. The ultra-high wear resistance is more than 20 times that of the high manganese steel hammer.
2. It has good resistance to mechanical shock and thermal shock.
3. Wide range of application, basically applicable to all crushing industries.
4. After suitable welding with steel or other materials, the working and cost performance of carbide hammer have achieved highly, so it has gradually become a hot demand in the market.
