Frequently Asked Questions (FAQ)
Q1: What equipment is the square hammer head suitable for?
It is mainly suitable for hammer sand making machines, composite sand making machines and some impact crushing equipment, especially for high-wear and high-impact sand making working conditions.
Q2: What are the advantages of ZGCr28Mo3 high-chromium alloy hammer head compared with high manganese steel?
ZGCr28Mo3 high-chromium alloy has higher hardness and wear resistance. Its service life is usually more than 3 times that of ordinary high manganese steel hammer heads, and it is especially suitable for crushing high-hardness and high-abrasive materials such as granite and river pebbles.
Q3: What is the hardness range of the square hammer head?
After reasonable heat treatment, the hardness of the working part of the hammer head can reach HRC 62–65, which balances wear resistance and certain impact resistance.
Q4: Is the high-chromium alloy hammer head prone to fracture?
No. Shandong Hengtai Intelligent Manufacturing adds molybdenum, nickel and rare earth elements to ZGCr28Mo3 material, and adopts bimetallic composite structure design, which effectively improves the brittleness problem of high-chromium alloy and is not easy to fracture under normal working conditions.
Q5: What is a bimetallic composite square hammer head?
It adopts liquid-liquid composite casting process: the working part of the hammer head is high-chromium alloy for wear resistance; the hammer shank part is high-toughness low-alloy steel for impact resistance. The two materials are integrally cast, balancing wear resistance and toughness.
Q6: What materials is the square hammer head suitable for?
It is suitable for sand making and fine crushing of high-hardness and high-abrasive materials such as granite, river pebbles, basalt, quartz stone, cement clinker and high-silicon stone.
Q7: Is the performance stable under high-temperature working conditions?
Yes. ZGCr28Mo3 high-chromium alloy has slow hardness attenuation under high-speed friction and high-temperature environment, with good thermal stability and certain oxidation resistance, suitable for long-time continuous operation.
Q8: How often does the square hammer head need to be replaced?
The replacement cycle is related to material hardness, feed particle size, equipment speed and other factors. Under the same working conditions, its service life is usually more than 3 times that of ordinary high manganese steel hammer heads, which can significantly reduce the number of shutdown replacements.
Q9: Is customization available for square hammer heads?
Yes. Custom production can be carried out according to customer equipment models, dimension drawings and actual working conditions, including single-piece customization and batch processing.
Q10: How to extend the service life of the square hammer head?
Suggestions: Strictly control the feed particle size and avoid over-specification large materials; prevent metal impurities from entering the crushing chamber; ensure that the hammer heads are replaced uniformly in sets to avoid unbalanced stress; regularly check the wear condition and replace the hammer heads that reach the limit in time.
