Service life is 3–5 times that of ordinary high manganese steel blow bars
Impact Resistance Without Fracture
The low alloy steel buffer structure can withstand high-speed material impact of 30–40m/s
Long-Term Stable Operation
Slow hardness attenuation at high temperature
Casting deformation ≤2mm
Suitable for continuous high-intensity operations
Application Scope
- Applicable Equipment: Impact Crusher
- Applicable Materials: Granite, basalt, river pebbles, cement clinker, iron ore, quartz sand, gangue, tunnel muck, construction waste and other complex materials
Frequently Asked Questions (FAQ)
Q1: What is an ultra-high chrome alloy dual-liquid composite blow bar?
The blow bar adopts the synchronous pouring forming of two metal liquids, ultra-high chrome alloy and low alloy steel, which combines the high wear-resistant working layer and the high toughness buffer layer into one, achieving the optimal balance between wear resistance and impact resistance.
Q2: What are the advantages compared with ordinary high manganese steel blow bars?
Under the same working conditions, its service life can reach 3–5 times that of ordinary high manganese steel blow bars, and the impact resistance is significantly improved, which can effectively avoid problems such as fracture and block falling.
Q3: What equipment is suitable for this blow bar?
It is mainly suitable for various types of impact crushers, and can be used in medium crushing, fine crushing and sand making working conditions.
Q4: What material working conditions is it suitable for?
It is suitable for high abrasion and high impact working conditions, including granite, basalt, river pebbles, cement clinker, iron ore, quartz sand, gangue, tunnel muck, construction waste and other complex materials.
Q5: How does the dual-liquid composite structure prevent blow bar fracture?
The installation and stress-bearing parts adopt low alloy steel with strong toughness as the buffer layer, which can withstand high-speed material impact of 30–40m/s and significantly reduce the risk of fracture.
Q6: Is it suitable for continuous high-intensity operations?
Very suitable. The product has slow hardness attenuation in high-temperature friction environment, and the overall deformation of the casting can be controlled within ≤2mm, which can run stably for a long time.
Q7: Is the blow bar customizable?
Yes. Customized solutions for size, material ratio and structure can be provided according to crusher model, material characteristics and working condition requirements.
Q8: What maintenance matters need to be paid attention to during use?
It is recommended to regularly check the wear condition, use the blow bars in a reasonable rotation, and replace the parts that have reached the wear limit in time to ensure crushing efficiency and safe operation of the equipment.
Q9: Can selection and technical support be provided?
Yes. Shandong Hengtai Intelligent Manufacturing can provide professional selection suggestions, working condition analysis and overall solutions for wear-resistant parts to help customers reduce comprehensive use costs.
