Hot Rolling Production Line for Wire Rod, Rebar Production Integrated

1. The block mill group adopts the top 45° crossing arrangement, which reduces the height of the long axis, not only increases the stability of the unit, but also reduces the equipment weight. The operation and maintenance are also more convenient.

2. Adjacent racks are arranged at 90° to achieve non-twisting.

3. Roll box and panel of wire rod mill adopt integral structure, with cantilever roller rings. Eccentric bushings are mounted in the roller box to adjust roller gap. Oil-film bearing and roll shaft are installed inside eccentric bushings. For roller at the cantilever, cone type sleeve is used for fixing the roll ring at the end of the roller.

4. The bevel gear box consists of box body, drive shaft, spiral bevel gear pair, and synchronous gear pair. All gears are of hard tooth surface grinding gear, spiral bevel gear accuracy of grade 6, cylindrical helical gear accuracy of grade 5, fully meeting the need for high speed and smooth operation of the roll shaft;

5. The roll box and the bevel gear box are connected directly by bolt. When assembling, the roll box body extends into the bevel gear box, so that the roller shaft gears are respectively engaged with two synchronous gears in the bevel gear box. The roll box and bevel gear box are positioned by two locating pins, and roll box of the same specifications can be interchangeable.
