TMT ROLLING MILL [CODE NO. 1900] What are TMT Steel Bars: The full form of TMT is Thermo Mechanical Treatment; in this the steel bars are passed through a specially designed watercooling system. After the bars pass, the outer surface of the bars solidifies while the core remains hot. This creates a temperature gradient in the bars.

Rolling schematic view Rolling visualization. In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of is classified according to the temperature of the metal rolled.

The looper control of hot strip finishing mill is one of the most critical control items in hot strip rolling mill process. It is a highly complex nonlinear system, with strong states coupling and uncertainty that present a difficult control challenge. Loopers are placed between finishing mill stands not only to control the mass flow of the two stands but also to generate a constant specific ...

Steel factory hot rolling mill problem definition. The function of the hot rolling mill is based upon the simple mechanism of using rolls to press steel slabs and reduce their thickness, as illustrated in Fig. 3. Before slabs can be rolled into hot rolling mills, slabs should be heated to the deformation temperature using reheating furnaces.
