Tungsten Carbide Rings are a type of tool material composed of tungsten carbide and cobalt, known for their high hardness and wear resistance. These rings are used as work rings in stands of pre-finishing rolling mills, finishing rolling mills, and reducing sizing mills.
Usage Instructions
1. Choose the appropriate rings that match your rolling mill requirements.
2. When installing the rings, follow the instructions precisely. Incorrect installation, such as improper fit between the ring and arbor or spacing, can lead to malfunction. It is crucial to ensure the rings meet technical specifications and clean them along with the arbor and spacer rings before use. Avoid hitting the rings with hammers or hard objects during assembly.
3. Cooling is essential to reduce thermal corrosion, fatigue, and stress on the roll rings during operation. This helps maintain optimal performance. Recommended cooling parameters include water temperature below 25°C, pressure between 5-6 bar, and a flow rate of 24-30 m³/hr per stand. Water should be jetted radially at an angle of 15-30 degrees relative to the rotation direction of the rings. The water column width should be twice the groove width, and it must be directed directly into the grooves without scattering or misting.
Water Quality Requirements
For YGH series: pH 7.2 medium or weak alkali water
For YGR series: pH 7.2 or weak acid water
The solid particle content in the water should be less than 15 mg/L.
Even under ideal cooling conditions, fatigue cracks may develop. To prevent further growth, re-machine the pass when the crack depth reaches 0.2 mm. Otherwise, the growing crack could cause sudden failure.
Recommended Pass Life
Pre-finishing Rolling Mill Stands: 3500-4000 tons
Finishing Rolling Mill Stands (1-2): 1800-2500 tons
Finishing Rolling Mill Stands (3-4): 1800-2500 tons
Finishing Rolling Mill Stands (5-6): 1500-2000 tons
Finishing Rolling Mill Stands (7-8): 1500-2000 tons
Finishing Rolling Mill Stands (9-10): 600-1200 tons
Reducing Sizing Mill Stands: 600-1200 tons
Groove Repair
To completely remove fatigue cracks, the groove must be re-dressed deeply. Checking for remaining cracks is challenging and inconvenient. Here are recommended re-dressing depths:
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-finishing stands: 1.2-2.0 mm
