Rolling mills are not a standard machine tool, nor are they built for stock. They are designed and built-to-order to specifically accomplish an end product or process. At one point during the industrial revolution in America, the United States led the world in hot and cold rolling, plate mills, slabbing mills and blooming mills.

- Hot Rolling is done in the 2-High Roll stands. Theory of Rolling Angle of Bite Top Roll Bottom Roll Input H0 Output H1 Theory of Rolling Angle of bite is 25-30 Degrees in case of Continuos Mills and a max of 20 Degrees in case of Cross-country Mills. The picture also indicates that the more the Roll Dia the more is the spread.
Rolling is one of the key processes in metal manufacturing, but there are two ways to 'roll' steel: hot rolling and cold rolling. It is a common misconception that these processes relate to a metal's specification or grade; instead they refer to how a metal is processed at the mill.. Hot rolling
Outline of reversing cold rolling mill and rolling method As illustrated in Figure 1, a reversing cold rolling mill is structured mainly of a mill proper, a winding machine (pay-off ree l), an entry winding machine (tension reel) and a delivery-winding machine (tension reel).

Jun 18, 2014· Roll pass design is an essential part of long product rolling process, since the long products are rolled between the shaped rolls in the long product rolling mills. Roll pass design generally means the cutting of grooves in the roll body through which steel to be rolled is made to pass sequentially to get the desired contour and size.
NOTE: Hot-rolling and cold-rolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hot-rolled or cold-rolled. HOT-ROLLED STEEL. Hot-rolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000° F.

The vibration demolding of the crystallizer leads to slab thickness deviation in continuous casting processes. Therefore, in this paper, the dynamic model of the hot strip rolling mill vibration resulting from entry thickness deviation is proposed and its dynamic characteristics are studied. First, the dynamic model of vertical vibration in the hot strip rolling mill is established based on ...
Severe vibrations, known as chatter, occur often in both hot and cold rolling of steel. A recent chatter outbreak at the second stand of hot strip mill in Hastings, Australia, prompted an investigation into the causes of chatter by a literature review, the development and deployment of mathematical models, and a rigorous analysis of plant observations.
In this paper, a real application of opti- mal control of a hot rolling mill is presented. It is used the state space model formulation in the minimization of the strip thickness variations.
