Product Introduction
Hot‑rolled compression springs are heavy‑duty springs manufactured by heating metal bar stock to high temperatures, coiling it, and then subjecting it to quenching and tempering. The underlying principle is to reduce the material’s hardness at elevated temperatures for easier forming, followed by heat treatment to restore strength and elasticity, enabling these springs to withstand extremely high loads.
Applicable Scenarios and Typical Size Ranges As follows, particularly suitable for heavy-duty equipment with stringent requirements for strength and durability:
-
Engineering and Mining Machinery: vibration screen springs, crusher springs, etc.; typical wire diameters range from 8 mm to 60 mm, with a coil ratio of 3 to 12 and an mean diameter not exceeding 460 mm.
-
Railways and Transportation: freight car springs, suspension springs, etc., with a free height ≤ 900 mm and a height-to-diameter ratio of 0.8–4.
-
High-voltage switchgear: Specialized springs for the power industry, with wire diameters typically ranging from 16 mm to 40 mm and mean diameters ≤ 400 mm.
-
General-purpose heavy industry: shipbuilding, bulldozers, excavator springs, and more.
Core Parameters and Process Standards The following specifications shall be referenced:
-
End treatment: Typically, tapered, closed, and ground‑smooth ends are used to ensure perpendicularity and stable load-bearing.
-
Applicable standards: Chinese national standard GB/T 23934-2015 or U.S. standard ASTM A125-24.
Special Reminder : These products are typically non‑standard customizations; when placing an order, please be sure to provide drawings or detailed specifications (material, wire diameter, dimensions, load capacity, and operating environment).
