satisfactory correlation between the strip widths, thickness to the diameter of steel pipe. The work has been focused to investigate the variation in strip thickness, while forming the strip in a rolling mill for constant roller loads and constant line velocity. It was found that there is negligible change in the thickness of the strip while ...

A 10 mm thick plate is rolled to 7 mm thickness in a rolling mill using 1000 mm diameter rigid rolls. The neutral point is located at an angle of 0.3 times the bite angle from the exit. The thickness (in mm, up to two decimal places) of the plate at the neutral point is _______. This question was previously asked in. GATE PI 2018 Official Paper.

Flat rollers are used for reducing the thickness of sheet metal and imprinting patterns into the metal. Wire rollers are used for rolling and reducing the diameter of a wire. Combination rolling mills come with a roller that has a flat and groovy surface. Although more convenient, they sacrifice the width of the flat surface.

II. ROLLING MILL: Various rolling mill configurations are available: 1. Two-high rolling mill: consists of two opposing rolls. These rolls may rotate only in one direction (no reversing) or in two directions (reversing). 2. Three-high rolling mill: allows a series of reductions without the need to change the rotational direction of the rolls. 3.

But "cold rolled strip" is rolled in "strip mills" that are narrow cold mills. The raw material for it is generally "hot rolled sheet" that has been pickled and slit into narrow widths. The end product has thickness variation which is less than sheet mill industry tolerances and is often produced to custom characteristics.

Each heavy-plate mill features its own individual layout. That depends on the product mix, the product geometries, and the installation site. Common to all mills are the main process sections: reheating furnaces, mill area with one or two reversing 4-high stands, plate cooling and hot plate leveler, cooling beds, shearing line, finishing line, heavy plate line, and heat treatment line.
