Balasen can undertake various engineering machinery industry components, not limited to engine components (such as cylinder blocks, cylinder heads, flywheels, etc.), working device components (such as buckets, boom arms, etc.), chassis components (such as track shoes, drive wheels, support wheels, etc.), hydraulic system components (such as hydraulic motors, hydraulic cylinder blocks, multi way valves, etc.).
Key Points in Production of Construction Machinery Castings
Hardness Requirements:
The hardness of engineering machinery castings usually needs to meet certain standards. For example, the hardness range of gray cast iron is generally Brinell hardness HB 100-220, and after quenching treatment, the hardness can reach Rockwell hardness HRC 48.
Tensile Strength and Elongation:
The tensile strength and elongation of castings are also important quality indicators. For example, the empirical relationship between the tensile strength and hardness of gray cast iron is: when σb ≥ 196 N/mm², HB = RH(100 + 0.438σb); when σb ≥ 796 N/mm², HB = RH(44 + 0.724σb).
Chemical Composition Requirements:
The chemical composition of castings has an important impact on their performance. For example, ductile iron castings need to meet specific chemical composition requirements, including the contents of elements such as carbon, silicon, manganese, phosphorus, and sulfur.
