Wear Resistance Cemented Carbide Tool / Roll Rings For Ribbed Steel Bars

YGH20,YGH25,YGH30,YGH40 ROLL RINGS FOR HIGH SPEED ROLLING OF RIBBED STEEL BARS

1. Description

Cemented carbide roll ring is a lind of tool material which consists of tungsten carbide and cobalt with high hardness and wear resistance.

2. Applications

YGH20: Maximum hardness, excellent wear resistance in the series. Used in the last -2 stans of god high speed finishing mills for rolling common and hard steel bar.

YGH25: Higher wear resistance, moderate impact resistance in the series. Used in the last 1-3 stands of good high speed finishing mills for rollin common and hard steel bars.

YGH30: Moderate wear resistance and impact resistance, good for general purposed. Used in the last 1-4 stands or all stands of finishing mills.

YGH40: Best for general purposes. Used in the front stands of good mills and in the rear stands of common mills.

YGH45: Used in the first and second stands of finishing mills and in the stands of pre-finishing rolling mills. For every stand of rolling lines for low speed rolling, low precision and unstable operation.

3. Specifications

YGH55: Maximum binder content in YGH series, ood toughness and thermal crack resistance. Used in the stands of pre-finishing rolling mills and for roll rins for hot rolling of ribbed steel.
