1 Based on a 2001 survey of 40 worldwide hot strip steel mills. Two grades of the material are used in the pinch roll application. The grades are both hypoeutectic alloy gray cast irons, quenched and tempered to the range of 60-70 HSC. The standard material is alloyed with nickel, chromium, and molybdenum.

Coiler pinch roll is one of the most important key components in hot rolling line [1].The quality and wear rate of the pinch roll surface determined the quality of the strip steel and the service life of the pinch roll [2], [3], [4].Since the rolling temperature of high-strength steel is obviously higher than that of low-strength steel, the temperature of high …

Initial Pinch, Three Roll. One of the most common plate rolling configurations, the initial-pinch system entails introducing the plate to the rolls so that roll A and B grip the part, while roll C performs the first prebend. Next, you turn the material 180 degrees and insert the plate to prebend the other edge.

4-Roll: The 4-Roll plate roll design is by far the most popular as it allows rolling to be accomplished in a single setup and keeps the material clamped tightly during the entire operation. Designed with 2 rolls vertically stacked in the middle to "pinch" the material the remaining 2 rolls move laterally to prebend the leading and trailing ...
