Details Description
The pre-finishing mill is the pre-rolling section for the 45° non-twist heavy-duty high-speed wire finishing mill. The drawings are completed by domestic design conversion.
The rolled piece is rolled into the required size and accuracy that meets the requirements of the finishing rolling mill by means of a two-strands, non-twisted and tension-free continuous rolling (with a looper between the racks).
The finishing mill adopts the Morgan Five-generation top-crossing 45° top-crossing torsion-free heavy-duty unit. Φ230 (8′′)×5+ Φ170 (5′′) 10 units are arranged, and the main motor is used to drive 10 sets of configurations for torsional rolling.

Laying Head of Wire Rod Mill
Laying head is used to fix spinning pipe and hollow shaft, which is derived by bevel gear in the driving box. There is a pipe inside the bevel gear. Water-cooling drive pipe is between the pipe and hollow shaft. Water-cooling drive pipe is used for cooling the pipe and it will protected the bearings of the hollow shaft from high temperature of rolled piece.
Iran Wire Rod Production Line
The whole wire rod rolling mill line consists of 28 stands rolling mills. The 16 roughing and medium rolling mills are arranged in a single strand wire rod mill line, and the pre-finishing to the collecting station is the double-line arrangement. The 10 pre-finishing rolling mills and finishing rolling mills are all Morgan block mill, of which the finishing mills are 45° top cross no twisted wire rod mills.
