Down Coiler Pinch Rolls.
Many hot strip steel mills around the world are realizing the benefits of the Xtek Bemcalloy™ Pinch Rolls. The inherent lubrication property of the graphitic constituent in the Bemcalloy™ material, along with the natural resistance to adhesion of dissimilar metals, is the basis of the pickup resistance of the material. This resistance to pickup of the Bemcalloy™ material has proven to eliminate the rejection of coils due to poor surface quality that is attributable to adhered debris on the pinch roll working surface.
The metallurgical attributes of the Bemcalloy™ material promote resistance to both adhesive and abrasive wear. This wear resistance allows for extended campaign lengths, and uniform and predictable wear throughout each campaign that the pinch roll is in service. The Xtek Bemcalloy™ Pinch Rolls also require less stock removal during regrinding, maximizing the stock available throughout the entire life cycle of the pinch roll.
Xtek Pinch Rolls are engineered for optimal performance and a value-added solution to the demanding needs of the hot steel strip coiling application.
The top pinch rolls are supplied as an assembly comprising a forged alloy steel through-shaft, two forged alloy steel hubs, the Bemcalloy™ sleeve, and associated hardware.
The bottom pinch rolls are supplied as an assembly comprising a forged alloy steel through-shaft, the Bemcalloy™ sleeve, and associated hardware. In both the top and bottom pinch rolls, the sleeve is a horizontally, centrifugally cast, thick-walled piece with a specific Bemcalloy™ chemistry that has been tailored to meet the specific needs of the application.
