What are the main categories of hammer crusher hammer head of Sanxiang stone crusher machine factory?

The hammer head of the hammer crusher is more and more widely used, and is one of the core parts of the machine. The relative weight is arranged on the hammer shaft of the crusher rotor, and the material is broken by direct impact when the rotor is running at high speed. According to the different nature of the material to be crushed, the types of crusher hammer used are not the same. So the crusher hammer produced by Shandong Sanxiang Heavy Industry Co., Ltd. can be divided into what categories? Let me briefly introduce to you the classification and characteristics of the crusher hammer produced by my company.
One: forging crusher hammer head
The forged hammer head used in the hammer crusher is suitable for crushing pebbles, coal gangue, limestone, etc. The train wheel steel (material 65Mn, good impact resistance, strong toughness, good wear resistance, not easy to break) is used to forge the metal billet repeatedly with forging machinery, so that it has a certain mechanical properties, a certain shape and size, after a special quenching heat treatment method, to ensure that the hammer working area to get high hardness, high wear resistance.
Through forging, the defects such as as-cast loose produced in the smelting process of metal can be eliminated, and the microstructure can be optimized. At the same time, the mechanical properties of forgings are generally better than those of castings because the complete metal flow line is preserved. Forging hammer head is favored by the majority of users because of its cheap price, economic and durable characteristics.
Two: high steel crusher hammer head
Shandong Sanxiang Heavy Industry Co., Ltd. production of alloyed high manganese steel wear-resistant hammer, reliable quality, wear resistance of traditional high manganese steel three times, the crusher hammer is widely used in a variety of soft rock crushing stone production line. With the continuous development of wear-resistant materials, high manganese steel has gradually become unsuitable for the development of modern casting industry. With the birth of chrome-molybdenum alloy steel, high-chromium cast iron and nickel hard cast iron material hammer, high manganese steel hammer has a trend of being gradually replaced, but the high toughness of high manganese steel is not comparable to other wear-resistant materials hammer, and its stability is also a big selling point. High manganese steel crusher hammer toughness is good, good process, low price, its main feature is that under the action of greater impact or contact stress, the surface layer will rapidly produce work hardening, its work hardening index is 2-3 times higher than other materials, wear resistance is greatly improved.
Three: high chromium alloy rock crusher hammer head
High chromium alloy crusher hammer head hardness is good, is an ideal wear-resistant material hammer head, but the toughness of high chromium alloy steel part is poor, in the absence of hammer support is easy to break, so the hammer handle part is generally high manganese material, the overall casting process is bimetal composite technology. However, the traditional manufacturing process is complicated, the process requirements are more strict, and the price is higher.
Four: carbide stone crusher machine hammer head
Carbide hammer that we often say wear-resistant steel hammer, compared with other materials, has higher hardness, bending strength and impact, thermal fatigue resistance, good thermal hardness, low cost and other characteristics, to solve the high manganese material prone to crack, welding, crack, falling and so on. For coal gangue and other impurities such as iron and other impurities to be crushed materials, the use effect has improved significantly.
Carbide hammer advantages:
1, ultra-high wear resistance, is more than 2 times of high manganese steel hammer head.
2, with good resistance to mechanical shock, thermal shock performance.
3, a wide range of application, basically can be adapted to all crushing industry.
Five: bimetal alloy crusher hammer head
The crusher hammer with two different metal liquid pouring is a bimetal hammer, and the bimetal hammer has hardness and wear resistance while ensuring the toughness of the hammer handle.
The temperature of hammer head quenching is crucial, generally according to the thickness of the parts wall to choose the appropriate quenching temperature, the higher the quenching temperature, the higher the hardenability, so in the hammer head production must develop a reasonable casting and heat treatment process.
If the crusher hammer head casting is not proper, it will cause defects such as pores. When the casting system of the hammer head of the crusher is not designed correctly, the metal liquid will be swirled into the gas, resulting in the formation of pores. When casting hammer exhaust is poor, the gas can not be discharged from the mold will also lead to the generation of pores, which requires us to strictly control the pouring temperature when pouring, and can not be interrupted evenly when pouring, in order to facilitate the casting exhaust, you can use inclined pouring.
To sum up: Shandong Sanxiang Heavy Industry Co., Ltd. production of stone crusher hammer head through the company's technical department and casting workshop workers continuous research and development and practice, the formation of forging hammer, high manganese steel hammer, high chromium alloy hammer, wear-resistant steel hammer as the representative of the product series, customers can be purchased according to their actual production situation. In the next step, Shandong Sanxiang stone crusher machine factory will continue to adhere to the research and development of wear-resistant products for the crusher, and strive to come up with more suitable products for our customers.
