Natural Mill Camber • Natural mill camber, which is a slight camber present in a beam when it is received from the mill, will exist in most beams • If the natural mill camber is at least 75% of the specified camber, no further cambering by the fabricator is required 34 • If camber is not specified, the beams will be fabricated and erected ...
The three high rolling mill utilizes the principle of passing the work back and forth to achieve a series of reductions. Unlike the two high reversing mill, the three high mill has three rolls that always spin in the same direction. An elevator mechanism lifts and lowers the work so that it can be passed back and forth through the rolls.
Rubber compounding was performed on a two-roll mill (Lab Walzwerk MT 6″×13″, Rubicon, Germany) in a three-stage process. In the first stage, the rubber was mixed with zinc oxide, stearic acid, CB, and Struktol or IPPD. Then the rubber/MLG masterbatch was …

Aug 16, 2001· A mill alignment usually takes one or two days and is most often done by a professional. Every day, the mill operator should use a setup chart and follow all operating procedures. The operator also should know the chemistry, Rockwell hardness, width, and thickness of the strip entering the mill and should document these values.
and compared to the center roll buildups and found to be a close match. With the machine down, the white buildup was found to be a filler material. Two contributing factors combined to create this quality problem. First, the filler streaking on the center roll would not be a problem if the center roll doctor was working properly.
