Today's economy dictates cost savings and rewards sustainability. Hence, it's imperative to consider refurbishing a roller instead of replacing it. This is especially the case when the roller is more complex. At C.R.E.W., we've refurbished or repaired hundreds of different rolls. Refurbishing takes into account many different things. It may be as simple as replacing a broken or worn journal, or re-grinding the O.D. to clean up. It can be as complex as re-shelling and re-journaling a double walled heat transfer roll. In any case, the decision to refurbish versus replace comes down to what is the best bang for the buck in terms of both price and lead time.  Some examples of refurbishing can be one or more of the following:
We have recently installed a special sub-arc welder that is designed to build up the outer diameter of roll bodies (either new or refurbished) by laying down a continuous circumferential weld on the roll. Overlay thicknesses that cannot be efficiently done by plating or coating are readily achieved, and adhesion (which is a problem with plating) is not an issue. We've made and refurbished carbon steel rolls used by a major film manufacturer, overlaid 1/8'-3/16' thick stainless steel on the O.D. for corrosion resistance, then ground and chrome plated the stainless steel overlay for hardness purposes. Likewise, we can overlay a carbon steel roll with an overlay of carbon steel to 'grow' a worn roll back to its original size. Sometimes stainless steel is specified on drawings of rolls for which the stainless roll body has to be made from rolled-and-welded plate because stainless pipe or tubing isn't available for that diameter. In these cases it's more economical to use carbon steel tubing with a stainless steel overlay.
