Ürün Açıklaması
The Tungsten Carbide Rings is a kind of tool material which consists of tungsten carbide and cobalt with high hardness and wear resistance.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.
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.
Water Quality Requirement
For YGH series PH 7.2 medium or weak alkali water
For YGR series PH 7.2 or PH 7.2weak acid water
The content of solid particles in the water<15 milligram/litre
Even in the perfect cooling condition, the fatigue crack will appear. To prevent it from growing, we need to re-machine the pass timely when the fatigue crack reaches 0.2mm deep. Otherwise, the growing crack may cause the roll breaking anytime.
The Regular Pass Life Is Recommended As Follows
Stands of pre-finishing rolling mill: 3500-4000 tons
1-2 Stands of finishing rolling mill: 1800-2500 tons
3-4 Stands of finishing rolling mill: 1800-2500 tons
5-6 Stands of finishing rolling mill: 1500-2000 tons
7-8 Stands of finishing rolling mill: 1500-2000 tons
9-10 Stands of finishing rolling mill: 600-1200 tons
Stands of reducing sizing mill: 600-1200 tons
Repair Of Groove
In order to remove the fatigue crack completely, we need to re-dress the pass deep enough. Actually, it is quite difficult and inconvenient to check if the fatigue crack is still there or not. Here are some suggestions of re-dressing for your reference:
Roll rings for 9-10 finishing stands : 0.4-0.6 mm
Roll rings for 1-8 finishing stands : 0.7-1.2 mm
Roll rings for pre-fiishing stands :1.2-2.0 mm
