  • Rolling stocks (made popular several years ago by investor Wade Cook) are stocks that repeat a certain pattern of trading. These stocks have both a support level that they do not trade below and a resistance level that they do not trade above. When looking at a daily chart they make a roller coaster pattern between these two levels. There are really only two ways for you to find rolling stocks.

  • John G. Lenard in Primer on Flat Rolling (Second Edition) 2014. 3.5 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well but under pressure with elastic deformation the friction is much less except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).

  • rolling process consists of passing the steel between two rolls revolving at the same speed but in opposite directions. The gap between the rolls is smaller than the steel being rolled so that the steel is reduced in thickness and at the same time lengthened. Two rolls opposite to each other together are called a "stand". A rolling mill may

  • Steel PipeSteel pipes are long hollow tubes that are used for a variety of purposes. They are produced by two distinct methods which result in either a welded or seamless pipe. In both methods raw steel is first cast into a more workable starting form. It is then made into a pipe by stretching the steel out into a seamless tube or forcing the edges together and sealing them with a weld.
