Forged Intermediate Roll for 8hi Mill
Forged Steel Rolls for Rolling Mill
1. Description
    The forged rolls are widely used on some tough stands of hot rolling mill, such as BD stand and blooming stand to perform with excellent strength to avoid some rolling accidents. Meanwhile, it is also a good choice to work on the cold rolling mill as backup roll and work roll. The whole process form melting, casting, forging, heat treatment to final machining and packing is under control of TANGSHAN WEILANG quality system.

7. The Operation of Rolls
1.) Clean off grease, dust and rust from roll surface before taking regular inspection, pay special attention to roll surface, there should be no marks, bruises,rust or cracks on roll surface, do not use the roll on mill with surface cracks.
2.) Before rolling starts, check carefully the surface quality, material and hardness of steel strips to be rolled, strips joint areas should be smooth and without bumps.
3.) For high speed, wide range and large reduction rolling practice, or when environment temperature is low, carry out pre-heating practice to the roll before rolling starts. Under normal rolling condition, run the mill in low speed for re-heating before rolling starts.
4.) Carry out re-grinding practice strictly according to roll management regulation, do not wait until surface defects are found before re-grinding. For each time of re-grinding, make sure to remove completely the fatigue layer and re-hardening layer from the rolls.
5.) Make sure to spray cooling water onto the rolls evenly and fully during rolling, so as to avoid hardness drops or cracks generation of rolls due to high working temperature or regional high temperature.
6.) Roll journal should be properly lubricated and cooled, so as to avoid excessive heat which may damage roll journal surface. Bearing should be fully lubricated and cooled as well to avoid journal break down.
7.) Rolling environment and strip surface should beclean, falling of foreign matters or ply rolling are not allowed.
8.) Avoid rolling accidents caused by sticking, chew-up, strip break or skidding, in case these accidents occurs, replace the work rolls, intermediate rolls and back-up rolls immediately, and carry out inspection and re-grinding accordingly.
