Product Description
Alloy Steel Rolls for Square Base Initial Rolling Mill
Centrifugal and Statical Adamite Steel Rolling Mill Rolls
1. Description
    According to different requirements the carbide contents of the adamite rolls varies. When wear resistance is required, the content of the carbide must be higher; but when the strength is the main factor, it is necessary to select the lower content of the carbide. The heat treatment is nomalized and tempered. A soft anneal will transform the pearl to nodlar form when the hardness is lower; while the strength relief anneal which has no influence on the structure must be adopted when higher. The lower hardness rolls have better strength properties and better resistance to fire cracng. The  Adamite rolls are widely used in the roughing stands of various rolliing mills. In most case, we make this type of roll by static cast. Its microstructure consists of little graphite, pearlite and fine carbide. With proper heat treatment, we can make this roll have a wear resistance close to iron rolls as well as strength & toughness close to steel rolls. Meanwhile, the low hardness drop form the body makes it workable with dep groove in the billet mills, universal mills and heavy section mills. Sometime, when it works as back-up roll on a narrow strip mill, we make it by centrifugal cast double poured with a core of nodular iron.

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.
