Rolling Mill Stand slab mill rebar mill wire rod mill plate mill
Steel grade: Carbon steel, Alloy steel
Thickness: 6-45mm
Width : 1200~2600mm
Length: Max 18000mm
Unit plate: 4.6 ton Max.
Screw-down has the electrical APC；
The precision of the rolling control depend on hydraulic AGC；
The mill has the section cooling of the roll, high pressure water descaling and the dust cleaning.
It has the roll gap meter and rolling pressure meter. These signal can be used as the feedback of the pressure and position.
The work roll bearing was four row tapered roller bearing. The backup roll bearing was dynamic pressure oil film bearing.
The material of the work roll was indefinite chill cast iron. The material of the backuproll was special alloyed forged steel.
The bottom of the mill has the device of ladder cushion. The height of the lower roller can be adjust automaticly.
The final mill has the function of working roll bending.
It reserved the Vertical Edger after the roughing mill stand. This vertical Edger has the AWC system. It can control the width of the plate. It also can control the shape of the head and tail of the plate. The yield rate can be improved accordingly.
The work roll assemble and the backup roll assemble can be changed quickly. The working roll and the backup roll can be send to the roll grinding shop directly and be regrinded and assembled there.
Rebar Hot rolling mill
Materials Specifications
Continuous casting square billet size is 150mm x 150mm; the length of the continuous casting billets inside the furnace need to be controlled around 6000 ~ 12000mm. Optimizing and length requirements are based on product specifications, with a predetermined length of the continuous casting billets putting into the furnace.
