• Roll Drive Design Considerations for Steel Mill Rolling Operations (.pdf)
  The conveying system that links one process to another is the lifeblood of any rolling mill. Lose this ability to move product and you lose production. As anyone in the steel industry knows, if a single component can shut down production of a multi-million dollar steel mill, this component...
• Biodegradable Lube for Metalworking Operations
  In aluminum rolling mill operations like this one, Alcoa, Inc., tested ARS's new biobased metalworking fluid and preferred it to the petroleum-based lubricants. A new metalworking fluid derived from soybean oil rather than petroleum is proving a smashing success in trial runs by Alcoa, Inc...
• Plastic Bearings
  and electrical switch-gear, rolling-mill, and water-turbine bearings. In small instruments and clock motors, laminated phenolics serve as structural members as well as a bearing material. They have excellent strength and shock resistance coupled with resistance to water, acid, and alkali solutions...
• Supergrinders boost productivity, profit
  of a button. A complete machining cycle takes just 12.5 min. This doubled the productivity in the roll shop, indicates Klenner, and the quality of the ground rolls improved. “The rolling mill now runs considerably smoother and our error rate decreased significantly,” he adds, “which results in a dramatically...
• Large-Diameter Bearings
  Large-diameter bearings have no precise definition. But a bore diameter of 12 in. or greater is used to define the size range that distinguishes large bearings from small ones. Some large bearings, such as steel-mill roll-neck bearings, are manufactured, selected, and mounted in the same way...
• Bearings take the heat
  for lubrication obviously cannot use conventional lubricants. Particulates Mill scale, silica dust, sawdust, kaolin, coal, fly ash, talc, flour, grain dust, and similar particles are typically small enough to breach bearing seals. In lubricated bearings, particulates can combine with grease or oil to form...
• Bronze and Copper-Alloy Bearings
  , good alignment, and a minimum Brinell shaft hardness of 300 to 400. They are used in high-load, low-speed applications such as trunnion bearings, gear bushings for off-road vehicles, rolling-mill bearings, and in internal combustion engines for connecting-rod bearings, valve guides, and starters...
• Barely scratching the engineered surface
  delivery in high-pressure diesel-engine injectors needs a 1-m m-thick coating, while a roller in a steel mill may use a 3-m m coating, for example. Coatings are also tailored to the application and use different process conditions. Components typified by rolling contact such as bearing races generally use...
• Glossary of Forging Terms
  in the regular processing operation. Axial rolls In ring rolling, vertically displaceable, tapered rolls, mounted in a horizontally displaceable frame opposite from but on the same centerline as the main roll and rolling mandrel. The axial rolls control the ring height during the rolling process...
