Announcements For Use
1.You should select the appropriate rings to meet the rolling mills.
2.For installing the rings, you must be exactly according to the instructions. Any incorrect operation, for example, the fitting between ring and arbor or the space rings is too tight or too loose, may cause the roll failing to work. It is also very important to check if the rings confirm to the technical requirements and clean the rings, arbor and spacer rings prior to rolling. It is strictly prohibited to hit the rings with hammer or other hard objects while assembling.
3.Cooling is intended to reduce the influence on roll rings thermal corrosion, fatigue and stress during milling. It can prevent optimizing the performances of roll rings. The reference data for cooling are as follows: The temperature of cooling water is below 25ºC, pressure of cooling water is 5-6 bar with a water volume of 24-30m/hr/stand. The water is jetted in a radial direction and the angle between the water jet and the rotating direction of roll rings is 15-30 degrees. The width of the water column is 2 times that of the groove and the water should be jetted directly into the grooves and the water should not be scattering or misty.
This kind of rings are used as work rings in stands of pre-finishing rolling mills, stands of finishing rolling mills and stands of reducing sizing mills.
