The main steel types are spring steel, cold heading steel, and free-cutting steel. For high-end products such as steel and tool steel, the product specification has been expanded from φ5.5～φ16mm to φ5.5～φ40mm, and the coil weight has increased from 1.7 tons to more than 2.1 tons (the coil weight has increased by more than 20% on the original basis).

The P/F line is an important part of the high-speed wire rod production line, and its important functions are to complete the process of wire coil accumulation, transportation, cooling, packaging, weighing, and coil unloading.

The existing bearing rail is a 16# heavy-duty flanging groove Steel, 16Mn material. With the increase of the high wire coil weight, the bearing capacity of the track is obviously insufficient, and problems such as wear and clamping often occur during use; especially at corners, because of the long accumulation track and many bends, overload often occurs , Frequent equipment failures in which the traction chain, drive chain and output shaft of the reducer are pulled off, which not only affects the conveying process, but also affects the subsequent processing speed and the production efficiency of the entire production line.
