The traditional high manganese steel hammer head has poor wear resistance, short service life and large consumption of materials. To this end, we use a bimetal composite hammer produced by bimetal technology to integrate the wear resistance of high chromium cast iron and the toughness of steel, opening up a new field of application of anti-wear cast iron. The first choice for grinding parts. The bimetallic composite hammers of crushers and fine crushers produced by our company are combined with various alloy elements according to different materials and different service conditions. Through special purification treatment in front of the furnace and interface treatment of liquids of different materials, the hammers can be improved service life purpose. The wear-resistant part of the hammer head has a hardness of HRC60-65, and the connection with the hammer handle is made of high-strength structural steel.
Features of Huishun composite hammer head
The hammer head is made of high-wear-resistant high-chromium alloy and has good wear resistance. The hammer handle is made of tough manganese alloy steel, which has good toughness and is not easy to break. The two are organically combined using a bi-metal composite production process. Together, the composite hammer head integrates toughness and wear resistance, making the product both wear-resistant and non-breaking. It is a combination of the advantages of steel and iron. Jiutai dual-liquid bimetal composite hammer head has good wear resistance, impact resistance, safety and reliability and other comprehensive performance.
The dual-liquid dual-metal composite hammer is suitable for stone production in building materials industries such as brick factories, large and small stone factories, steel plants, coking plants, machine-made sand, cement plants, etc. It is used for crushing limestone, granite crushing, cobblestones, and coal gangue hard materials. The use results show that the bimetal wear-resistant hammer head has improved wear resistance than ordinary high-manganese steel hammer heads. It is especially suitable for highly abrasive limestone and other materials with high silicon content and poor breakability. It is used by many large-scale cement production lines, sand and gravel Respected by users.
Advantages of Huishun Hammer Breaking Composite Hammer Head
1. Special composite casting process
The head of the dual-liquid bimetal composite hammer produced by Jiutai is made of high-chromium alloy material, and the hammer handle is made of low-alloy steel material with good toughness. Thermal compounding is used to melt two materials with different properties and functions in the liquid state. As a whole, it solves the problems of easy breakage, falling pieces, and U-turns of the alloy-inlaid and twice-composite-cast hammer heads, and improves the safety of the hammer head.
2. Special element ratio
In addition to carbon, chromium, silicon, manganese, copper, molybdenum and other elements, Jiutai casting hammers also add vanadium, titanium, antimony, rare earth and other elements to refine the grains and improve wear resistance.
3. Optimize heat treatment process
The heat treatment process of Jiutai composite hammer head is to heat to 1100℃ for heat preservation, then come out of the furnace, undergo chemical water toughening treatment, and then perform low-temperature tempering at 600℃ before being air-cooled. The hardness can reach 62HRC-65HRC. The process is mature. Jiutai has the best hammer head hardness. and toughness requirements are very high, and being responsible to our customers is our mission.
4. Good economic benefits
The hammer head is not easy to break and has a longer service life than a forged hammer head or a high-manganese steel hammer head. It meets the demand for frequent replacement of hammer heads in sand and gravel production lines and has good economic benefits.
5. Provide measurement and customized hammer head services
The hammer head used can be customized according to the drawing. If there is no drawing, our Jiutai surveying and mapping personnel will help you customize it after surveying and mapping.
Huishun composite hammer head undergoes strict heat treatment to create a composite hammer head
The quenching and tempering heat treatment of the hammer head is very critical. The overall tensile strength is not only required to be above 85OMPa, but also requires considerable toughness and plasticity. After processing the hammer hole, surface quenching is performed on the striking area of the hammer end. Not only is the surface hardness required to reach HB410~460, but the internal hardness gradient is required to be controlled within a strict tolerance zone. Therefore, at least one hammer head is damaged in each batch. In addition to taking a test piece near the hammer hole for comprehensive mechanical testing, it is also necessary to select any piece and cut it along the symmetrical center of the hammer head, and test its hardness at equal intervals according to the specified distance from the surface. The change of the hardness gradient is within the specified distance. Within the tolerance range, the hardness of this batch of hammer heads can be considered qualified. Sonic and magnetic particle inspection are carried out one by one to ensure that there are no defects and cracks inside and outside the hammer head, ensuring the quality of the hammer head.
