The alloy wear-resistant hammer head is formed in one step using the leading two-liquid composite lost foam vacuum suction casting process. It is matched with a variety of alloys and loaded with precious elements such as molybdenum, vanadium, titanium, and niobium. The Rockwell hardness reaches 62-65, and it has high wear resistance and high Excellent hardness and toughness, the service life is more than 3 times that of traditional high manganese steel hammer heads; the hammer head part is made of high wear-resistant high chromium alloy, and the hammer handle is made of manganese alloy steel with strong toughness. The hydrothermal composite production process is used to infiltrate and combine the two liquids, and the internal structure is dense, which is both wear-resistant and non-breaking, so that the hammer head meets the requirements of toughness and wear resistance at the same time.
The alloy wear-resistant hammer head is used in building materials industries such as brick factories and stone factories. It is widely used for crushing granite, cobblestone, limestone, bauxite and other minerals. The alloy wear-resistant hammer head is especially suitable for crushing materials with high silicon content and easy to break. Materials such as highly abrasive limestone with poor performance are highly praised by many users of large-scale cement production lines and sand and gravel fields.
Strict quality control
1. The casting temperature and heat treatment time of the hammer head of the crusher are precisely controlled, and high-quality high-chromium alloy raw materials are selected. The procurement cost is 20% higher than that of the same industry.
2. Every aspect of the production of cast wear-resistant parts is monitored by 24-hour cameras. Before leaving the factory, it must be inspected one by one by the laboratory, quality inspection department and other departments, and monitored at all levels to eliminate pores and cracks and ensure the quality of each batch of hammer heads.
3. The accessories department strictly controls the quality, inspects the hammer heads leaving the factory one by one, and tests the hardness, strength and toughness of the finished wear-resistant parts. Products with a hardness less than 60 cannot leave the factory.
Advantages of alloy wear-resistant hammer head
1. Special composite casting process
The head of the dual-alloy wear-resistant hammer produced by our company 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 a liquid state. As one body, the composite area can reach 100%, which completely solves the problems of easy breakage, falling pieces, and U-turns of alloy-inlaid and twice-composite casting 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, the casting hammer head also adds 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 the wear-resistant hammer head is to heat it to 1100°C and keep it warm, then come out of the furnace, undergo chemical water toughening treatment, and then perform low-temperature tempering at 600°C. Finally, it is air-cooled out of the oven. The hardness can reach 62HRC-65HRC. The process is mature, and the hammer head hardness and Resilience requirements are very high, and being responsible to our customers is our mission.
4. Reliable performance and wide application range
The wear-resistant alloy hammer head has high anti-wear efficacy and safety performance, effectively solving the contradiction between hardness and toughness. It is a wear-resistant hammer head developed for the crushing of abnormal limestone containing SiO2. It is especially suitable for crushing hard, High SiO2, highly abrasive limestone is suitable for working under severe abrasive wear conditions, and has a service life that is more than 50% longer than ordinary high manganese steel hammer heads.
5. Good economic benefits
The hammer head is not easy to break, and its service life is more than three times that of 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 strong economic benefits.
6. Provide humanized services
The hammer head used can be customized according to the drawing. If there is no drawing, we have professional surveying and mapping personnel to help you customize it after surveying and mapping.
